If you don't trust the reliability of diesel engines you haven't done enough research for this swap. Diesels, especially these older, simpler, emissions free ones, are the absolute best choice for this application.
Robert Wiersema lol yeah because you don’t operate a boat the same way as a car, you don’t rev a LS motor to damn near it’s max rpm for 3 hours straight but you can do that with a diesel. That LS motor will have to be pushed to its max and even then I won’t come close to the torque and reliably of a diesel motor
He's going to ruin the boat for the content lol. Whatever, it pays his bills. But you're 100% correct. There's only 1 correct answer, and it's another diesel swap.
I am Team Diesel. They have less issues, and heartaches if you maintain it annually, and properly. Diesel Engines are like the dog that’s always loyal to you. You just have to stay on top of the maintenance schedule. I am currently a Diesel Mechanic trust me that they are worth the investment. You should have just bought a couple of wrecked Dodge Ram 3500HDs with the 6.7L Cummins Turbo-Diesel. You would have had a better power to weight ratio with twin inline 6s. Than you would have with the GM LSX engines. I love the GM Performance LS Motors but, the 6.7L Cummins I6 has way better Power, and Torque.
That’s his concern. He is going to lose a lot of money when he sells the boat if he buys expensive diesels. Gas engines are cheaper. But I agree, diesel is better. If only money wasn’t an option.
Bang out another thousand in fuel if you gas I have seen both diesel and gas in boat your double Or triple the fuel. as long as the diesel is turbo fix it and keep it. There is something call low rolling resistant and gas cars do good but under full load diesel push through water and burn less
Him going to gas is a massive mistake. He will definitely regret it later. I am also a heavy diesel mechanic and there is a reason why with such a large boat you have diesel engines.
I am strongly against any pickup engine in an yacht, there is a reason why it’s 14L of engine, it’s to be able to run hard for hours like 90 to 100 percent hard. No truck engine can handle that stress. Smaller engines are capable of big power numbers but for a Very small amount of time.
and gas engines cant run at full power for that long .. a gas engine will die under 30min if u run at full load and open throttle ... lcos , boats and gensets use diesel cuz u can run them for really long time without any problem ... here in my country some trains travel a 1000km and one emd pulls them from start to end continuously running for 2 days and only stopping for refuel and 20min station stops.. try that with your petrol engine lol. ships travel from country to country for 30days or more and they run these engines close to their full speed and yet have little to no problems .. a day or two trip to the sea will kill those ls engines!
6.7 cummins make 300hp at 3300rpm weigh about 1000lb and cost $4-8kish out of a generator and are meant to run at peak power for long periods of time. Gas engines in yatch are stupid and you will burn them out in your first trip.
Bang out another thousand in fuel if you gas I have seen both diesel and gas in boat your double Or triple the fuel. as long as the diesel is turbo fix it and keep it. There is something call low rolling resistant and gas cars do good but under full load diesel push through water and burn less
Average life of a marine application of an automotive engine is 750 hours, an outboard engine 1500 hours, Diesel engine 10,000 hours. You need an industrial engine, not a race car engine. A car can never put a load on an engine like pushing something heavy fast through the water. Good luck keeping good fuel in your tanks. Diesel fuel has a much better shelf life and has about 30% more heat value by volume. Chief Engineer Paul Haugan
He will find that out when he has to rebuild those gas engines every 500 hours!!! Ask ANY offshore high performance boat owner how much those engines really cost!!!
You haven't been here long have you. Chris usually makes the wrong decision on everything. With something like this he should consult with a few experts who know what they are doing. Anyone involved in boats or the marine business would tell him this is a terrible idea.
Comment update : i was talking to my uncle which is a marine engineer because i was curious. He actually knows that boat very well, he's master was actually about that same boat here in italy, he confirmed what my doubt was even though you'll loose weight dropping the old engines you will have to restore the weight you loose due to buoiancy or had a ballasting sistem which is almost impossible and not cost efficient. Also the weight would have to be distributed as in origin to keep the stability of the boat ok
I bet it doesnt effect it as much as you think, Your probably in the neighborhood of a couple hundred pounds per engine weight savings. Thats equivalent to like 1 1/2 fat guys. In that size boat its moot, Shit my lil 23 foot center console was made for twin engine and single engine outboards and thats a 400 lb + hanging off the back of the transom aka the most leverage possible. Being that those engines sit almost mid ship a 500lb weight difference isnt really a big deal imo.
Bizarre decision considering the amount of great Diesel engines builders you have at your disposal. Those marine engines are big for a reason! You don’t see tanks with LS’s in 🤷🏻♂️🤦🏻♂️
Once you strip out the entire interior and replace it with a petrol tank you should be fine for short voyages . Having destroyed the yachts equilibrium you will need to compensate with a mountain of lead ballast aft , excellent project . You should call it Dog,s Dinner . It will be worth about that much . Please continue , highly entertaining . Good luck.
I worked for Cummins in Southern Indiana for a number of years as an assembly engineer. One of my areas of responsibility was the V903 assembly line. The V903 engine has been in production in on form or another since the 1960s, so there are parts available. There are a number of parts on the engine that contain oil passages. The V903 is exclusively produced now for military application only now.
i have seen a couple 903's in highway trucks back in the early 80's, i drove one for a short time, they were kinda here today, gone tomorrow, the 400 big cam 3 will get a page in trucking history.
painful watching a newb take apart a marine engine and be confused by a destroyed impeller. Literally the most common failure in a marine engine. Right there. Its great to learn.
This guy is an absolute tool. Diesels are meant to run at low rpm and high torque for literally days on end. Those ls engines will be scrap in a couple of years, if he is lucky.
@@llaughton69 yeah, and he keeps comparing modern light-weight aluminum engines to old cast iron marine 454s 🤣 Theres a reason GM still uses cast iron blocks for their heavy duty 6.0 engines. The LSXs hes going with are an extremely poor choice for that massive vessel, the only modern gas GM engines I'd even remotely consider would be 6.0s or 8.1s.
@@llaughton69 weeks, at best. he couldnt even maintain a fucking diesel in his boat, he will NEVER stay after all the bullshit a gasser needs to live in that environment. never mind the fact that if he doesnt change the props the boat will likely never get on plane, the engines will overheat and thatll be all she wrote.
Chris really needs to take the time to read all the solid info in the comments, people are disappointed in this choice for multiple (very good) reasons. Ditching the Diesel engines in a boat of this size is not a good idea, and he is going to be essentially lighting a pile of cash on fire to find that out the hard way.
oh man this is gonna be fun to watch the gas motors struggle to push that heavy beast, and fail to last because they're not designed to run at sustained RPMs under heavy load.
@@phonzy Your right and wrong with that. They were designed with endurance racing in mind but, they were thinking along the lines of a 5K lbs vehicle at max; Not a several TONS of weight. He'll blow the motors in 10 trips to the ocean or shorter.
phonzy Endurance racing in cars doesn’t generally last longer than 24hrs, most teams would expect to rebuild the engine after a 24hr race. Boats have to put out huge amounts of torque for thousands if not tens of thousands of hours. This is nearly as dumb as building a mustang fastback and calling it Eleanor and is likely to lead to a similar financial situation.
"Kinda the b is for build way" translates to ignore all advice and do an engine swap that will never get finished or work correctly. Not one of the engine swaps on this channel is a success. It would nice if Chris did something properly for a change.
Lol I was thinking the same thing, when has B is for Build ever made a reliable vehicle that is finished. He doesn’t take the time like other channels such as Rob Dahm who spends 4 years work on and perfecting just 1 car. They build it for content and move on. A boat is the last thing you want to have problems on.
@@OccasionalBoss I agree with the both of you. I think he gets off on building rather than using. It's quite the flip from how I would do it in the same situation, but oh well. His boat and channel.
@@justsomeguy6550 Oh shit I forgot about that one too, it reminds me of Top Gear, Jeremy's Toybota (the first one) had too much weight in the front because, well, pickup truck engine, so it kept nosediving and taking on water.
Well I believe rebuilding these diesels and and putting them in is the best option these type of boats have gas Motors all over the place even bigger boats than this have dual gas powered 4 cylinders
With the RPM, torque, prices, and properly building a matching/mating set, yes. I wouldn't trade my diesel for anything due to the capability and cheaper running costs.
I guess we all get to see exactly why an LS swap is a bad idea... huge amount of modification required, no performance improvement, reduced reliability, higher risk, higher cost... with that said I love the channel and I get that some people just need to figure it out themselves.
Surely Banks Power would have some engine packages you could use? If it HAS to be a new powertrain. The LS option is going to be like having a couple of drag engines howling away under the floor, DRINKING gas.
Correct. This is NOT going to end well. Those engines are not built to push this much weight. Not to mention Chris puts this boat in salt water. That’s why marine engines are set apart from street engines. They can handle the salt water. If this was a fresh water speed boat yes.
A couple of episodes ago when you dry docked the boat 🚢 you clearly stated that there was a repair shop down the street who repairs these engines and you was going to be taking the engines to them for rebuild... what happened to doing that???
It's a sponsored build. I wouldn't be surprised if they bought the boat knowing the engine was on the way out. Either way, in 6 months, the boat will be sold or returned back to stock.
Retired cummins 903 tech. For future reference : You did the first thing you should have done last no mater the the make or type engine,cut open and check the oil filter. Crank case was already contaminated and you were going to have to change oil and filters regardless of what you found.
The boat won't plane right, it's going to either create a cavitation issue, or it will nose dive on plane if it can get there. Either one will be disastrous. A boat of this size needs the weight distributed properly, and low slung to perform and have the hull achieve proper lift.
“A decision has been made and I know it’s not going to be a popular one”... that would be because it’s absolutely the stupidest decision possible. You are making a terrible mistake.
He's a nice guy, but he's got no idea what he's doing. He talks to the camera describing how he's going to take this "stuff" off, and unbolt "these guys" so we can "lift this unit out" etc. It's just painful to watch. I appreciate his ambition, but for God's sake learn the correct terminology and apply some critical thinking to a build.
@@Bread996 You seem to be a decent mechanic knowing even Your terminology. He is a TH-camr. Given his 1.3 million subbies and the chicks-for-free deals he gets on a regular basis, he is even a *_successful_* TH-camr. Being a decent mechanic does bring You subs in the higher four to mid fife digits, with some even in the six. So it doesn't matter calling stuff "these guys" and "that stuff", obviously in contrary: He'll just get a bigger boat when "content" requires it, or starts still another project, additionally to the seven unfinished ones, because people like the drama, they like the rushing into projects, obviously, they even seem to like the sloppy research ("parts availability ...") and his lack of knowledge or education. So it could turn out counterproductive should he start doing proper research and using terminology too specialized for the buncha 1.3+ million subbies he weighs into stupid deals ....

As a person with over 10 years mechanical experience and terminology. I enjoy his methods lol. I have even learned some custom fab knowledge from oscar cool channel.
@@DaveyLuckky I was a petrolhead ever since, but I'm a (racer's sailing yachts) boatbuilder by profession. I did (and do, given customers are able and prepared to afford it) my share of vintage ply Riva runabouts, too, and I think there actually *_are_* Riva boats suited for big twin gas V8s, or V12s even, like Ferruccio Lamborghini's legendary Aquarama. Chris' Riva yacht though - not so much. But we'll see I reckon.
Engine overheated when first impeller failed. Bore scoring occurred due to overheating and it got progressively worse. You burned the oil due to the bore scoring. Oil gets sloshed into the score marks and burned on the combustion stroke. That's where the oil went and why you can't find it. It went out the exhaust.
'The goal is to replace this boat' If you fix it properly and put it all back to stock you should be able to sell it for what you bought it for, it is a Riva after all. But I can already tell it's going to be in dry dock with a couple blown gas engines and sold for scrap value. Fix the Riva and buy a cheap small boat to modify.
@@Grumpy_old_Boot Very common to rebuild a diesel. A boat with engines that need rebuilding is far from scrap. Getting rid of the engines and putting Corvette engines in it does make it scrap.
@@BobWiersema You missed the part about the wait and rarity of parts right? He has no way to fix the engines him self, so he has to rely on a shop to do it for him which will not be cheap and once again you are at the mercy of the shop being able to get the parts to the engine. also the 454 was not a stock option in any GM car.
I love all the marine engineers screaming at their monitors when you said diesels in a boat are unreliable. Bro whats goin on, you have content for the next year if you decide to finish properly all the projects you got. Ive watched literally every video you put out for years and years but its starting to get really hard lately.
@@martinwink2063 I know, but im pretty sure theres a big part of the audience that wants to see the Ls Lambo absolutely destroy on a drag strip, and the one seater, and the 240z bmw build that looks probably the scariest of em all. Properly tuned and finished (yes i know custom cars are never done) But we prolly wont. I like the guys and the "fuck it we can do it ourselves" mentality they have, thats the reason ive stuck with the channel since the brzs. I dont really mind the boat swap cuz im sure theyve done a bit more research than ppl give em credit for and it wont be all that bad. Theyve got so many great projects like 3/4 done not because they cant finish them but because of the next big thing they start.
You said it - no idea what Chris is playing at. 5 years to build a channel and 5 weeks to destroy it. As he said he's really getting into the "boating lifestyle" in 2021 we're making this boat and in 2022 we're making that boat. Sad to say but I'm a car guy, if this channel becomes a boat channel I am out.
I got a 42’ Regal it used to have twin 454. I found 2 300hr Cummins isl9 450hp military surplus. It originally used as a generator only paid $12000 for them. $5000 extra for all the marine conversion parts and I did everything myself. The boat cruising at 32 knots now 10knot faster and paid 60% cheaper than gas engine. You don’t have to break your wallet if you know what you doings.
@@adamvu119 if he were smart, then he wouldn't be building high performance small cube engines for his boat. He also wouldn't be using a racing engine builder who knows very little about marine products. If he were smart, then he would be looking for reman or used diesel engines. If he had any brains at all, and knew anything about marine anything, then he would have called all those chunks of rubber from the pump Impeller Vanes. If he were not an ignorant dumbass, he would have known what those set screws did on the 'shaft stabilizer' as he called it. If he weren't a complete moron, he would know how anodes work, and to NOT paint them, or the shafts of the trim tab rams. So, tell me again how smart this complete idiot is? He painted the fucking props on the damn boat, like he is going to be able to use them! He doesn't even understand that new transmissions and props will need to be installed with those stupid ass motors! He also expects to sell the boat in the future, but still does stupid shit like this! No one will ever buy this boat, since he will completely ruin it with the modifications he is making.
@@thomask.8533 I'm probably ignorant but why not just buy a pair of used diesel truck motors. They'd be smaller but I mean, probably would work better than a gasser.
Did you even try to find another 903? I'm finding dozens of vendors close to you with remanufactured 903 marine engines in crates ready to install for 6K. Wow.
@Lassi Kinnunen Yeah from what I'm reading on their website that's at least 12k each, for just a long block, not including any of the adapters, fuel injection, misc.
You can also get 903 engines from AAVs that just need a turbo. When the turbos go out, instead of just replacing the turbo, they replace the whole engine.
thats Cummins`s fault.. it takes longer to get a couple of gaskets for those diesels as the guys over at Texas Speed need to build him 2 complete new engines with everything on them. Dont forget: that marina where its now charges him a fortune in storage fees. So waiting for the rebuild of those diesels will probably cost him triple of what 2 new TSP engines do..
You can get complete remanufactured vta 903 500 hp for 5000 each they were in bradley fighting vehicles and they are nearly bulletproof it would have to be easier and better than going gas to get the torque you would need would take putting turbos on those 454s and making 1000 hp then those engines will loose their reliability
It's not taking a month to get gaskets from Cummins Maybe a month from the cheapest seller on eBay If he looked hard enough he could get parts same day or overnight A commercial boat or machine isn't sitting around for a month waiting
You dont buy a boat like that because "youll get your money back out of it" That boat isn't going to be worth much in resale without diesel power. Good luck.
Anyone who invests in a hobby knows that they never "make" money. On the other hand, no one wants to take a bath on it, either. I agree with the LSX engine choice.
Powerboats/Yacths generally depreciate a lot. They are luxury items, that become outdated, real quick. Same goes for Super Sports cars, and Super Luxury Cars.
The boat with the current engines condition is about worthless. Swapping to gas just brings all the baggage of making sure everything is marine/explosion proof rated. I understand he wants to build the engines, be far simpler to buy an 8.2l crate engine from Mercury in reality. Go for their 9.0l at 1350hp.
@@TheBeingReal those gas crate engines will not provide enough torque at the right RPM range to move the boat which is down low. That means he is going to have to buy new marine transmissions to match those higher rpm gas engines as well. talk about throwing fking money down the drain - wow.
Just looked for giggles. Diesel parts direct has all of the seals, bearings etc, in stock with a 1 to 4 day arrival time. Month long wait huh? This is a train wreck waiting to happen.
Yup, he never had any intention of repairing the diesels other than of morbid curiosity of seeing what failed. He could have easily found the parts or found a proper marine engine repair shop that would allow him to film the rebuild process. He’s doing this because the TSP engines are free and it’s TH-cam algorithm friendly, the boat will never work properly and hurt the channel in the long run as just another project that’s not finished or working right. Much like the LS Lamborghini.
@@adamgeorge8327 True, but he can get 2 texas speed HP engines at no cost plus a fat check for using 2 texas speed HP engines. So the choice is either pay a shit ton for diesels or get paid to use free motors.
Sorry Chris... I agree with almost everyone.... I think you’re making a “BIG, BAD MISTAKE!”... although I am rooting for ya!!!!!… I hope all goes well.... and please don’t take it in open water, I like your channel and would miss you a lot!
Hmm... Love the channel and love watching you guys push your limits, and to be honest I got hooked on TH-cam about a year ago partly based on this channel. I'm a fan, so it pains me to say this, but before LS swapping a yacht, how about you get the LS swapped Lamborghini drivable first? Hate to be so negative, but if you can't engineer an LS to be able to propel a Lamborghini at more than quarter throttle, how do you expect to make this work in a boat? Figure out all the things you didn't account for in that situation (like gearing to match the engine curve and tuning the engine to get the full potential out of it) and fix them, then take your new found knowledge and move on to new builds that push you further. I live by the rule of "If you're going to do it, then at least do it right." I'm starting to see this pattern where you try something cool, get it 90% done, put some lipstick on it, declare it done, then move on to the next project while the last one never really worked. It's a bit of a disappointment.
Have you taken into account that those heavy diesel engines are factored into the boats ballast ? I mean those gas engines don't even come close to the weight of one of those diesels you pulled out.
yeah he is going to be turning a lovely high speed plaining boat into a slow, loud, unreliable boat that has the bow buried so deep into the water they may as well have just got into a bath
Why exactly are you and others saying a gas engine is bound to fail in short order? Most boats (non-commercial) use gas engines and almost all outboard engines are gas. What makes this situation so much different?
Noah Ferrari I understand it’s a large boat, but what difference does that make exactly? 25 foot CC boats are running 110 hp yami outboards no problem. Why would twin small block chevys have an issue with this boat?
@@Dentistresponds a 903 makes over 2300 ft pounds of torque per engine thats the working load a engine produces the move a boat. i worked on tons of marine boats from skiffs to 100+ foot pleasure ships tbh 903is no where near as good as the inline cummins . Personally id repower with equiv Scania
@@Dentistresponds Marine grade engines are way different than car grade engines... Cars are expected to just use 100% power for a few minutes and then go light on the throttle, marine grade engines are 100% power for hours... That's ONE of many reasons.
You do wonder what he spends his money on with the subscribers and his views you would think he invest some back into his channel just seem to go cheap in just about everything he does.
Hard to get parts? People in the comment sections doesn't agree with that. Going for a gas on a marine application just to save couple of grands uh.. The value of a boat will go down more than you "save" with this setup + the money spent on gas. LS swap interesting? Yeah right.. you still have some unfinished LS project. Diesels are not reliable? If so then why diesels are used where continuosly high torque is needed. "Engines are pretty heavy and they need space". Of course they are! Thats why the boat is actually working properly. You could've gone to the interesting way by repairing those diesels but you took the boring usual way which is LS. I really liked this boat series until now =S.
"Diesels are unreliable", said no one ever. There's a reason why the some of the most in-demand engines are the 5.9L cummins, and it ain't because their unreliable, it's because they're the definition of reliable. A million miles?? No problem on a diesel, but rare on a gasoline engine. Diesels run cooler, are less complex, and more robust for prolonged max-load applications
Which is why second hand Cummings engines like the ones he's about to scrap are so expensive to buy, they're reliable and last forever if you maintain them properly. Personally I think he's making a big mistake but it'll be amusing watching him find out the hard way.
Imagine the conversation after the conversation. Hello, parts company counter guy, I need a part for a 468 big block that has been highly modified with xzy and blah blah blah. Do you have the part in stock for it? That will be fun for whoever buys this PoS down the road. Blaahaahaahaa
Top Tip: If you don't have an allen key the right size find a bolt head that fits into the allen socket, two nuts on the bolt thread and you are in business.
John not to mention he made a big deal about gaskets taking a month when it’s probably gonna take a year to swap those gassers in. Dude has no idea lol
He explained why it’s not more sensible lmao. Did you even listen. And obviously you didn’t watch him build his huracan for sema. Wayyyyyy more in depth and he got it done in time. If he didn’t have to pay to store the boat and had better equipment to work on giant diesels he would have rebuilt them. There’s a lot of variables you seem to have missed in the video. There’s many reasons those clapped out diesels aren’t going back in
odysseyrider1 there’s a lot of variables you seem to not get also like taking 6 tons out of a bottom of a boat and replacing it with maybe 1500 to a ton. Big issues.
I disagree, last video I would’ve agreed but after seeing the condition of them now no way, both motors require a full rebuild and that would run probably $30k (nzd) each providing you can find the parts. I still think diesel is the way to go but he’s gonna do what he wants to do lol
Chris I love the content but you still haven’t made ONE all out pass in your LS Lambo. If diesels aren’t your thing, pay someone to fix it correctly. You’ve got no less than 6 months of content with the projects you already have. You will 1000% regret going LS . They didn’t put those engines in there by mistake.
except when the boat was built... they didnt have the LS.. they had carbed old school big blocks... technology has come a long way since this boat came about. not saying i would have gone gas but.... i think the gas wont be this huge mistake everyone is saying it is...
@@MrDiva480 I’m an LS guy all day, but they don’t belong in boats this big, if they did, manufacturers would use them in new boats of this size, which they don’t, they use diesels
Just from reading the comments, with no boat or diesel experience, I've learnt so much...such as : ○Those shredded bits were from the impellor ○those metal bits are most likely from the oil cooler ○ weight distribution plays a big role ○fuel tank size needs to be increased ○you can get away with just replacing the liner, gaskets , bearings. ○torque and reliability of a diesel out weighs horsepower of a petrol engine ○ increase in fuel price... ○needs to make contact with a naval architect what else have I missed? Typing this out, so I can go to one comment if I ever require this knowledge. ..
@Kentucky Hillboy Because he thinks he using his $$$ well because Texas Speed is providing the engines... He hasn't considered things like how do I add 3600lbs of fixed/static ballast in the same location as the engines were. Or how am I going to add enough fuel capacity to keep my range while still having the rest of the comforts of the boat. He hasn't thought about over the horizon reliability... because he thinks of it as a lake queen not a blue water capable vessel. Basically he's treating this like its no big deal if the engines fail because they were free, not thinking it could cost him and anyone on board their lives if they fail. He wants a play toy and this boat is not one. If he wants a play toy build something to blow the jet off Finnegan's jet boat, don't screw with a blue water craft this way. Not without consulting a naval architect / marine engineer and following their advice completely.
"needs to make contact with a naval architect" Dude, he said in this video he is going to build a "really big boat" that is "his design" in 6 months in 2021/22. He clearly has never talked to a naval architect.
@@TheM750 , I was talking in the manner of weight distribution for this boat. ..basically, the buoyancy. ..the placement of the tank, the way the waves will hit the boat with lighter engines. ..etc
@Kentucky Hillboy I get it, I am neither a mechanic or engineer, but I am really interested the sciences behind how and why things work the way they do. Especially, when it comes to vehicles of any kind. My point really is that his decisions are going to backfire, cost him a boat load of money, and could kill someone. Do I know the answers. Not really other than the marine engineers / naval architects choose a pair of heavy ass diesels for some reason, and I can only infer from my research that they did so for many different reasons. The Original Comment lists them out pretty well. They are all things that B is for build will have to figure out handle and manage. Or he could have ordered the parts to repair it and done the over hauls either himself for youtube content or taken them to a diesel shop where they would have been ready to drop back into the boat probably within 2 weeks. Shops generally have some really good people to track down and get parts. So that's not really an excuse. I don't know what the cost of a rebuild would be on those engines but I would say it's probably less than the cost to make the modifications to have a pair of heavily tuned engines, and the associated changes to ballast, electrical, fuel, cooling and props.
Ballast I know I said this last time. The lighter engine means less ballast. Do your research on how much ballast/weight is needed to keep the boat upright. You don’t want to be in light waves and all the sudden the boat capsizes. You might have to add lead or something in the bottom of the hull.
Forgot I had a boat for a year. Suddenly needs content. Remembers he has boat. Breaks boat because previous owner sold it cheap because knew engine was coming out. B is for blowhard click baiting for views. I’m only watching this channel now for the epic fail of this boat. I have little to no respect for Chris and the gang. I’d be loyal follower and view all his videos if he went for doing things right. He is showing everyone how to not do it.
He didn't say how much time. Maybe two weeks or less? Besides, he did tell us what the downsides of repaired diesels, like weight, their inefficiencies, and their limits. The cost of rebuilding those engines making ever recover any money invested in the boat.
Ron LHeureux He’s lying about everything. You can get rebuild kits for that motor in 1-3 days. It’s also the most efficient and has been fine for 35 years in that boat. Properly rebuilt and it will last another 35 years. He could pull both motors and rebuild them both and that boat would be great. He wants to build a death trap that’s going to put not only his life at risk but anyone who steps on board including his girlfriend. This isn’t a car and when shot goes wrong on a boat out at sea things can go bad real quick.
26:50 it blows my mind how there are so many comments, arguments, advice from people with actual experience... and yet this is the choice. Absolutely mind boggling. Like I feel dumb for watching this but don't want to unsub so I can see the inevitable results. Hopefully you prove them wrong.
@@xenuno The majority rules if people don't watch anymore, just look at half of the TH-camrs from a decade ago that pull in a fraction of the views now because they didn't adapt to their viewer base.
I feel the engine swap was already decided on long ago, he is doing this for views and to get people to watch the next episode etc. The time it takes for parts and shipping is just an excuse. A deal has been made previously with an engine provider. A shame the old diesels wont get a chance to power the boat again, they really are the best option.(20 + years in the Navy and Rail locomotive world working on all sizes of diesel engines. They are suited for these purposes). I still like to watch and see the success and failures of the projects they attempt. I give it 6 months at least before they get all the systems sorted in the boat powering under its own engines.
I agree with you, I still find it intersting to watch. Its something different. There is a reason why all heavy equipment, semis, trains, ships everything that has a lot of weight uses a diesel engine.
@gary Fox thast 20th century thinking. Overhere in Europe the days of the diesel engines are numbered, 2030 may be the last year they are roadlegal.. after that they are outlawed in most cities. All the older cars, trucks and vans have already been hit with increasing environmental taxes, and because of that diesel sales have dropped significantly. Same goes for agricultural/building equipment, the emissions regulations on those make them so much more expensive is becoming more economically viable to not buy diesels anymore. (ps Im no diesel hater, just realistical. I recently scrapped my perfectly safe and reliable 1996 diesel van because of all the extra taxes and exclusion zones around here..)
@Lassi Kinnunen Not overhere.. diesels are OUTLAWED for commercial use in every major city by then.. If I had to guess: hybrid battery/hydrogen fuelcell powered trucks will be the future
You never get back what you put in a boat... Welcome to boat life... Personally I would stay with Diesel/ Also, boats have a "hull speed" put as much power as you want, you'll struggle to get past the hull speed of the hull design.
....."to much time to wait for parts for the diesels" ....orders custom built LSXs from Texas speed that still need to be marinised. Anyone else think it was always going to be a gas conversion no matter what?
Yea cause all the "cool" kids has an LS. Literally every comment I've read on this was reasion not to go gas and keep diesel but nope he wants an LS cause Cleetus McFarland has a few and he cool.
You are going to regret this choice. Might as well name the boat Bob, because that is all it is going to do. Bob around while tied to the dock unable to move under it own power.
“Putting money into thIs boat that we’re never gonna get back”. . . . . . Too Right. Seems right on course with gas engines. This boat will be a hole in the water into which sponsor money will flow unhindered. Underestimating the issues with this conversion will be interesting to watch. The diesel crowd feels like it’ll be watching a train wreck.
I don't think it's "the diesel crowd" as much as "the marine crowd" expecting a train wreck. Marine-rated engines have a lot of factors to deal with that don't come into play (as much) with a land-based vehicle. For one example, removing weight as he's doing will change how high the boat floats on the water. That reduces drag, sure, but if that boat isn't a planing hull, he's asking to capsize and sink, especially since he's looking to move fast. Then there's the problem of gas fumes. Marine gas engines have flame arrestors all over air intakes and exhaust to prevent fire and explosion. Chris touched on a few other points himself in the previous video, as well. This will definitely be interesting to watch, and it could work; I just hope he doesn't manage to get himself or someone else killed in this experiment.
He could, even without just the switch will cost more then fixing the old engines. He hasn't figured out he will have to redesgin the boat due to new engines/gas tanks (since he can use the old ones) all the supporting mods. /it will be like the lambo with two gas engines on temp 5 gallon tanks for a quick speed lap with the boat (25% done but pretending it is nearly done) just to upload a video and pretend it is done and move on. Honestly, he lost his ass on the boat and is scared of admitting his 30k saving he sunk into that boat is gone and will have to pay 5k more just to hual/dump it. However, he should admit it and move onto the powerboat, much more realistic for his small brain and ls engine idea.
And I am pretty sure he has to do that USCG inspection because he is a monetized TH-camr and makes money from his channel and sponsorships, and gets the more rigorous one for commercial vessels...
Hey Chris, love the channel. I think you really should save those LS engines for another project with Texas speed and wait to rebuild those engines. Remount them for proper ballast and get seatow to bring you to wet storage somewhere cheaper while you wait. I was so jealous when I saw that boat and pictured you taking it for long trips, overnighting, hell even taking it down to MX from where you are. Going with Gas motors are going to neuter that boat of everything that makes it amazing in my opinion. Just fix it the right way, keep diesel in it, and enjoy the adventure that comes with it. Put those two engines in some stupid speedboat build or something. Huge long-time fan, but I think you need to have a talk with some people that have a lot of experience in this field.
@@lawnmowerdude ...he's already agreed that diesel engines are the best option for this boat in the previous video, the proposed LS swap is clearly not about making the right choice...the fictitious 1 month time and expense for parts is just mental gymnastics to shoehorn the LS swap into this project...
All we can do now is trust that texas speed can come through with at least a somewhat competent marine LS conversion. (for the record, I don't think its possible)
Please! Rebuild those engines! Here in Brazil we have hundreds of those on marine applications running on the Amazon River and people love it! They are powerful and reliable. Thats the best option!
Ovcourse them engines are fitted for that specific boat he just thinks because its old thats how they worked back then leaving no room, when infact they are that size to balance that ocean worthy vessel. He cuts out at sea and a wave hits it, its good bye Chris and who ever else is silly enough to get on a gas powered yacht if it doesn't blow into a fireball it will probably capsize.
I'd be ok with new engines... if they were diesel. This boat will not run well or for long. Diesels are made to last, gas engines are made to blast. This all might sound cool and I admire your enthusiasm, but this is a bad idea.
Everywhere is full of rubber, "very bizarre" I'm laughing my ass off! PLESE consult a marine mechanic if you are this unexperienced in marine engines and boats (because this isn't a yacht in my view)...
Lol, I am a marine diesel mechanic, and I’m laughing at everything. The liners are probably leaking, through the o-rings. Also, those veins on the salt water impeller frequently go bad. Get jobs all the time like that.
Oh dude 100% I can't tell you how many I've done my first year at a full service shop. And the engine costing more than the boat is also a really common thing with boats like he's going to ruin this boat. Its designed to have big heavy engines astern of the mid point. That thing isn't gonna plane, handle, turn or even fuckin float right unless he puts 3000lbs of concrete in the rear. Dumb
Seriously how hard is it to replace a couple of liners? I’ve never worked on marine engines like this but have worked on industrial engines with wet liners and I don’t think it could be more simple. It’s easier than having the block bored out and honed when it reaches its service limit. How does he think he can replace a 14 liter engine with an ls?? This is like putting an LS into a semi and expecting it to haul a full load over a mountain pass because it has more horsepower lol.
The crank is also bad, seems like bearing material in the oil filter, who knows what they'd find at the bottom of the pan. But putting a car motor into a boat is almost as bad of an idea as putting one in an airplane. At least the boat keeps floating.
They have not indeed, i commented it a few times already, he needs to go with marine engines, texas speed does not have that kind of experience! Going with joh boomer or nelson racing or something that has experience is just a better overall idea.
Why y’all gotta hate? Like cmon man just respect the dudes decision. I don’t think y’all realize that not all TH-camrs have a lot of money. You have to realize that even tho TH-cam is an okay source of income, with all the cars he has, this makes it harder on his pockets. I am sure he wanted to repair the Diesel engines but with the cost to keep the boat out of the water plus at the dock where he lives is just a lot for him. He made a decision based on what he felt is right. I completely respect his decision and I will continue to watch his amazing content.
B is for bad decisions for the sake of content! 1. those gas engines wont last in that boat 2. the value of the boat is going to decrease significantly because of the gas engine fuckery (for someone whos concerned with ROI this is counter intuitive for sure) 3. petrol + boat with engines its not designed for can quite possibly = big fire/ big explosion 4. BALLAST?!?!?! do you not respect marine engineers or??? 5. did you really use reliability as an argument AGAINST diesels??? I could keep going but I wont... You lost me on this one. i was very much looking forward to some diesel content. instead we get ANOTHER LS swap somewhere it has absolutely no place being. Its the youtuber way I guess.
For real. This guy is killing me. On nearly every build there are a bunch of people in the comments who actually know their shit and are telling him the proper thing to do and he ignores all of it.
As soon as I saw the blue/black color of the water pump cover plate. Before they found the bits. I thought burned impeller. Someone ran the engine without raw water supply.
Yeah didn't that thing like catch fire or something not long after it was built. And I remember he took it to a show of some kind and it broke down on him and he had to spend half the time fixing it.
Two things: 1. You are seriously going to be missing the diesel torque. Good luck. 2. When you go to build your jet boat, talk to Mike Finnegan. A crossover video between you two would be awesome.
This could have been a great diesel engine rebuild series which I would have loved to see. We would have happily waited a month or more for parts and it would have cost alot less.
Even though you can get the parts next day from a number of online places. Including full overhaul kits with pistons, sleeves, bearings, gaskets etc. for less than $3000 for the pair of engines. What this is is a sponsorship deal from texas speed. and it is going to be a really lovely fireball that everyone can have a look at in about 3 months
You had a base explosion due to being overheated i bet it blew the oil out the path of least resistance aka the water pump seal. You could have also been experiencing blowby because oil does not normally come out of the water pump. That hole in the water pump is a weep hole for the coolant seal not the oil seal
Water pumps that bolt into the oil space (area where oil is?) have a seal for the oil on one side and coolant on the other side the space is to let either of them excape if they fail. Water cooled motorcycles are like this on there water pump as they dont drive the water pump off a belt either.
This is the right decision for more TH-cam content. Rebuilding the Diesel engines would’ve been boring, he’s trying something different and I think it’s great !
@@cleatusjr6063 Homeboy he legit asked for opinions and then fucking went stevie wonder CaUse OH LS swAPEd ITALIAN YATCH coNteNt dumbass is gonna get stuck in the middle of the ocean and good for him SMH
If you don't trust the reliability of diesel engines you haven't done enough research for this swap. Diesels, especially these older, simpler, emissions free ones, are the absolute best choice for this application.
I think he was questing the reliability of his current engines if he rebuilt them, not of diesels in general.
Are you saying that a LS engine won't operate reliably at full load for hours on end? :-)
Robert Wiersema lol yeah because you don’t operate a boat the same way as a car, you don’t rev a LS motor to damn near it’s max rpm for 3 hours straight but you can do that with a diesel. That LS motor will have to be pushed to its max and even then I won’t come close to the torque and reliably of a diesel motor
He's going to ruin the boat for the content lol. Whatever, it pays his bills. But you're 100% correct. There's only 1 correct answer, and it's another diesel swap.
Dale you are dead on! Going LS is really stupid quite frankly. This boat will be ruined with the swap.
I am Team Diesel. They have less issues, and heartaches if you maintain it annually, and properly. Diesel Engines are like the dog that’s always loyal to you. You just have to stay on top of the maintenance schedule. I am currently a Diesel Mechanic trust me that they are worth the investment.
You should have just bought a couple of wrecked Dodge Ram 3500HDs with the 6.7L Cummins Turbo-Diesel. You would have had a better power to weight ratio with twin inline 6s. Than you would have with the GM LSX engines. I love the GM Performance LS Motors but, the 6.7L Cummins I6 has way better Power, and Torque.
That’s his concern. He is going to lose a lot of money when he sells the boat if he buys expensive diesels. Gas engines are cheaper. But I agree, diesel is better. If only money wasn’t an option.
Bang out another thousand in fuel if you gas
I have seen both diesel and gas in boat your double Or triple the fuel. as long as the diesel is turbo fix it and keep it.
There is something call low rolling resistant and gas cars do good but under full load diesel push through water and burn less
Him going to gas is a massive mistake. He will definitely regret it later. I am also a heavy diesel mechanic and there is a reason why with such a large boat you have diesel engines.
I am strongly against any pickup engine in an yacht, there is a reason why it’s 14L of engine, it’s to be able to run hard for hours like 90 to 100 percent hard. No truck engine can handle that stress. Smaller engines are capable of big power numbers but for a Very small amount of time.
and gas engines cant run at full power for that long .. a gas engine will die under 30min if u run at full load and open throttle ... lcos , boats and gensets use diesel cuz u can run them for really long time without any problem ... here in my country some trains travel a 1000km and one emd pulls them from start to end continuously running for 2 days and only stopping for refuel and 20min station stops.. try that with your petrol engine lol. ships travel from country to country for 30days or more and they run these engines close to their full speed and yet have little to no problems .. a day or two trip to the sea will kill those ls engines!
6.7 cummins make 300hp at 3300rpm weigh about 1000lb and cost $4-8kish out of a generator and are meant to run at peak power for long periods of time. Gas engines in yatch are stupid and you will burn them out in your first trip.
Agree ^^ ...though I wish it wasn’t true

You don’t want tanks of petrol on a boat
Hell two bone stock 12 valves would be a better option then LSX's
Average life of a marine application of an automotive engine is 750 hours, an outboard engine 1500 hours, Diesel engine 10,000 hours. You need an industrial engine, not a race car engine. A car can never put a load on an engine like pushing something heavy fast through the water. Good luck keeping good fuel in your tanks. Diesel fuel has a much better shelf life and has about 30% more heat value by volume. Chief Engineer Paul Haugan
He will find that out when he has to rebuild those gas engines every 500 hours!!! Ask ANY offshore high performance boat owner how much those engines really cost!!!
I don't get it... That engine lasted for 30 years, would've lasted even more if properly maintained, but waiting a month for parts is too long?
It's business. Time = money when it comes to making TH-cam content. (plus boat dock fees etc.)
You haven't been here long have you. Chris usually makes the wrong decision on everything. With something like this he should consult with a few experts who know what they are doing. Anyone involved in boats or the marine business would tell him this is a terrible idea.

Comment update : i was talking to my uncle which is a marine engineer because i was curious. He actually knows that boat very well, he's master was actually about that same boat here in italy, he confirmed what my doubt was even though you'll loose weight dropping the old engines you will have to restore the weight you loose due to buoiancy or had a ballasting sistem which is almost impossible and not cost efficient. Also the weight would have to be distributed as in origin to keep the stability of the boat ok
I was wondering about this, thank you for explaining!
interesting. never thought of needing weight.
These guys are going to learn
I bet it doesnt effect it as much as you think, Your probably in the neighborhood of a couple hundred pounds per engine weight savings. Thats equivalent to like 1 1/2 fat guys. In that size boat its moot, Shit my lil 23 foot center console was made for twin engine and single engine outboards and thats a 400 lb + hanging off the back of the transom aka the most leverage possible. Being that those engines sit almost mid ship a 500lb weight difference isnt really a big deal imo.
@@Cameron-ur2tk the old motors are 2k lbs ea. new ones probably 5-600

@@supertoadhayden hopefully that someone isn't Chris
Texas Speed is a sponsor, he's going to get great support and prices on those engines - I can understand his decision.
Drop both engines at a Cummins shop. Two weeks later pickup your warrantied engines. Now you have several years of trouble free cruising.
Not that hard to rebuild. Why spend that much money when tearing it down is half the work. I would take the heads for a valve job and order 2 Ag kits
Once you strip out the entire interior and replace it with a petrol tank you should be fine for short voyages . Having destroyed the yachts equilibrium you will need to compensate with a mountain of lead ballast aft , excellent project . You should call it Dog,s Dinner . It will be worth about that much . Please continue , highly entertaining . Good luck.
I worked for Cummins in Southern Indiana for a number of years as an assembly engineer. One of my areas of responsibility was the V903 assembly line.
The V903 engine has been in production in on form or another since the 1960s, so there are parts available.
There are a number of parts on the engine that contain oil passages.
The V903 is exclusively produced now for military application only now.
i have seen a couple 903's in highway trucks back in the early 80's, i drove one for a short time, they were kinda here today, gone tomorrow, the 400 big cam 3 will get a page in trucking history.
painful watching a newb take apart a marine engine and be confused by a destroyed impeller. Literally the most common failure in a marine engine. Right there. Its great to learn.

Chris really needs to take the time to read all the solid info in the comments, people are disappointed in this choice for multiple (very good) reasons. Ditching the Diesel engines in a boat of this size is not a good idea, and he is going to be essentially lighting a pile of cash on fire to find that out the hard way.

The LS platform especially the LSX was designed with endurance racing in mind.
@@phonzy Your right and wrong with that. They were designed with endurance racing in mind but, they were thinking along the lines of a 5K lbs vehicle at max; Not a several TONS of weight. He'll blow the motors in 10 trips to the ocean or shorter.

I'm not even a diesel guy, but even I know diesel is much better for marine applications.
With the RPM, torque, prices, and properly building a matching/mating set, yes. I wouldn't trade my diesel for anything due to the capability and cheaper running costs.
Change the channel name to H is for Hairbrained.
I guess we all get to see exactly why an LS swap is a bad idea... huge amount of modification required, no performance improvement, reduced reliability, higher risk, higher cost... with that said I love the channel and I get that some people just need to figure it out themselves.
Less fuel efficient is big espically on a boat where dissel is cheaper than gas
Surely Banks Power would have some engine packages you could use? If it HAS to be a new powertrain. The LS option is going to be like having a couple of drag engines howling away under the floor, DRINKING gas.
Correct. This is NOT going to end well. Those engines are not built to push this much weight. Not to mention Chris puts this boat in salt water. That’s why marine engines are set apart from street engines. They can handle the salt water. If this was a fresh water speed boat yes.
A couple of episodes ago when you dry docked the boat 🚢 you clearly stated that there was a repair shop down the street who repairs these engines and you was going to be taking the engines to them for rebuild... what happened to doing that???

It's a sponsored build. I wouldn't be surprised if they bought the boat knowing the engine was on the way out. Either way, in 6 months, the boat will be sold or returned back to stock.
Retired cummins 903 tech. For future reference : You did the first thing you should have done last no mater the the make or type engine,cut open and check the oil filter. Crank case was already contaminated and you were going to have to change oil and filters regardless of what you found.
Hi Walt, for reference and to know. ¿What do you think about the price to get those engines to work again? and times to do a work like that?
The ballast should be interesting with taking out a few thousand pounds in the rear
The boat won't plane right, it's going to either create a cavitation issue, or it will nose dive on plane if it can get there. Either one will be disastrous. A boat of this size needs the weight distributed properly, and low slung to perform and have the hull achieve proper lift.
“A decision has been made and I know it’s not going to be a popular one”... that would be because it’s absolutely the stupidest decision possible. You are making a terrible mistake.

Chris' Riva yacht though - not so much. But we'll see I reckon.
Engine overheated when first impeller failed. Bore scoring occurred due to overheating and it got progressively worse. You burned the oil due to the bore scoring. Oil gets sloshed into the score marks and burned on the combustion stroke. That's where the oil went and why you can't find it. It went out the exhaust.
Exactly.
He didn't burn the oil, he removed almost all of it from the bottom of that boat in the previous video, he just can't find the source of the leak
Some oil surely went out the exhaust. But there also was gallons of oil under the engine...
Ya when they get the engine apart and don’t know what an impeller is and keep calling water intake fluid “coolent”
Yes. Nobody did the impellers. That's the first thing you do. Now you have impeller chunks and no cooling.

If you fix it properly and put it all back to stock you should be able to sell it for what you bought it for, it is a Riva after all. But I can already tell it's going to be in dry dock with a couple blown gas engines and sold for scrap value. Fix the Riva and buy a cheap small boat to modify.

also the 454 was not a stock option in any GM car.
I love all the marine engineers screaming at their monitors when you said diesels in a boat are unreliable.

@@martinwink2063 I know, but im pretty sure theres a big part of the audience that wants to see the Ls Lambo absolutely destroy on a drag strip, and the one seater, and the 240z bmw build that looks probably the scariest of em all. Properly tuned and finished (yes i know custom cars are never done) But we prolly wont. I like the guys and the "fuck it we can do it ourselves" mentality they have, thats the reason ive stuck with the channel since the brzs. I dont really mind the boat swap cuz im sure theyve done a bit more research than ppl give em credit for and it wont be all that bad. Theyve got so many great projects like 3/4 done not because they cant finish them but because of the next big thing they start.
You said it - no idea what Chris is playing at. 5 years to build a channel and 5 weeks to destroy it. As he said he's really getting into the "boating lifestyle" in 2021 we're making this boat and in 2022 we're making that boat. Sad to say but I'm a car guy, if this channel becomes a boat channel I am out.
I got a 42’ Regal it used to have twin 454. I found 2 300hr Cummins isl9 450hp military surplus. It originally used as a generator only paid $12000 for them. $5000 extra for all the marine conversion parts and I did everything myself. The boat cruising at 32 knots now 10knot faster and paid 60% cheaper than gas engine. You don’t have to break your wallet if you know what you doings.

@@charlieodom9107He very smart guy. He knows what he's doing.
" Perspective is only limited by that individual's knowledge."
@@adamvu119 if he were smart, then he wouldn't be building high performance small cube engines for his boat. He also wouldn't be using a racing engine builder who knows very little about marine products. If he were smart, then he would be looking for reman or used diesel engines. If he had any brains at all, and knew anything about marine anything, then he would have called all those chunks of rubber from the pump Impeller Vanes. If he were not an ignorant dumbass, he would have known what those set screws did on the 'shaft stabilizer' as he called it. If he weren't a complete moron, he would know how anodes work, and to NOT paint them, or the shafts of the trim tab rams.
So, tell me again how smart this complete idiot is? He painted the fucking props on the damn boat, like he is going to be able to use them! He doesn't even understand that new transmissions and props will need to be installed with those stupid ass motors! He also expects to sell the boat in the future, but still does stupid shit like this! No one will ever buy this boat, since he will completely ruin it with the modifications he is making.

Did you even try to find another 903? I'm finding dozens of vendors close to you with remanufactured 903 marine engines in crates ready to install for 6K. Wow.
@Lassi Kinnunen Yeah from what I'm reading on their website that's at least 12k each, for just a long block, not including any of the adapters, fuel injection, misc.
@@rotaryboots They're sponsoring the engines for free I believe, which is why he went with this bad decision.
and you can get full rebuild kits for $3000 total for the pair of engines
This was my thought as well sell the current engines to a rebuilder and buy rebuilt ones from the same guy. Get a better deal that way.
You can also get 903 engines from AAVs that just need a turbo. When the turbos go out, instead of just replacing the turbo, they replace the whole engine.
Chris: *does all the research to find out why diesel is more practical for a marine application*
Also Chris: huhehuehe LS go vroom vroom
thats Cummins`s fault.. it takes longer to get a couple of gaskets for those diesels as the guys over at Texas Speed need to build him 2 complete new engines with everything on them.
Dont forget: that marina where its now charges him a fortune in storage fees.
So waiting for the rebuild of those diesels will probably cost him triple of what 2 new TSP engines do..
You can get complete remanufactured vta 903 500 hp for 5000 each they were in bradley fighting vehicles and they are nearly bulletproof it would have to be easier and better than going gas to get the torque you would need would take putting turbos on those 454s and making 1000 hp then those engines will loose their reliability

Maybe a month from the cheapest seller on eBay

You dont buy a boat like that because "youll get your money back out of it" That boat isn't going to be worth much in resale without diesel power. Good luck.

Powerboats/Yacths generally depreciate a lot.
They are luxury items, that become outdated, real quick.
Same goes for Super Sports cars, and Super Luxury Cars.
This boat is about to depreciate nearly as fast as the Eleanor build did
The boat with the current engines condition is about worthless. Swapping to gas just brings all the baggage of making sure everything is marine/explosion proof rated.

@@TheBeingReal those gas crate engines will not provide enough torque at the right RPM range to move the boat which is down low. That means he is going to have to buy new marine transmissions to match those higher rpm gas engines as well. talk about throwing fking money down the drain - wow.

Yup, he never had any intention of repairing the diesels other than of morbid curiosity of seeing what failed. He could have easily found the parts or found a proper marine engine repair shop that would allow him to film the rebuild process.
He’s doing this because the TSP engines are free and it’s TH-cam algorithm friendly, the boat will never work properly and hurt the channel in the long run as just another project that’s not finished or working right. Much like the LS Lamborghini.

Hmm... Love the channel and love watching you guys push your limits, and to be honest I got hooked on TH-cam about a year ago partly based on this channel. I'm a fan, so it pains me to say this, but before LS swapping a yacht, how about you get the LS swapped Lamborghini drivable first? Hate to be so negative, but if you can't engineer an LS to be able to propel a Lamborghini at more than quarter throttle, how do you expect to make this work in a boat? Figure out all the things you didn't account for in that situation (like gearing to match the engine curve and tuning the engine to get the full potential out of it) and fix them, then take your new found knowledge and move on to new builds that push you further. I live by the rule of "If you're going to do it, then at least do it right." I'm starting to see this pattern where you try something cool, get it 90% done, put some lipstick on it, declare it done, then move on to the next project while the last one never really worked. It's a bit of a disappointment.
Have you taken into account that those heavy diesel engines are factored into the boats ballast ? I mean those gas engines don't even come close to the weight of one of those diesels you pulled out.
yeah he is going to be turning a lovely high speed plaining boat into a slow, loud, unreliable boat that has the bow buried so deep into the water they may as well have just got into a bath
The whole trim will be ruined
He can use Truly as ballast.
He can just add additional weight
It will be interesting to say the least.
I can't wait for the upcoming episodes , I've got my extra large bag of popcorn and soda and I'm ready for the shitshow!

Cost of parking it is crazy too

LS swap is not a good idea... it's not a car, the engines will suffer and fail very soon... then you'll have a paper weight boat.
Why exactly are you and others saying a gas engine is bound to fail in short order? Most boats (non-commercial) use gas engines and almost all outboard engines are gas. What makes this situation so much different?

pimpis Maybe or some other problem
Hard to get parts? People in the comment sections doesn't agree with that. Going for a gas on a marine application just to save couple of grands uh.. The value of a boat will go down more than you "save" with this setup + the money spent on gas. LS swap interesting? Yeah right.. you still have some unfinished LS project. Diesels are not reliable? If so then why diesels are used where continuosly high torque is needed. "Engines are pretty heavy and they need space". Of course they are! Thats why the boat is actually working properly. You could've gone to the interesting way by repairing those diesels but you took the boring usual way which is LS. I really liked this boat series until now =S.
"So preoccupied with whether or not they could, they didn’t stop to think if they should." A perfect quote for this situation.
Petrol on board ! No smoking , spark suppression , gas detection and still accidents happen.
Research that.
"Diesels are unreliable", said no one ever. There's a reason why the some of the most in-demand engines are the 5.9L cummins, and it ain't because their unreliable, it's because they're the definition of reliable. A million miles?? No problem on a diesel, but rare on a gasoline engine. Diesels run cooler, are less complex, and more robust for prolonged max-load applications

He explained why it’s not more sensible lmao. Did you even listen. And obviously you didn’t watch him build his huracan for sema. Wayyyyyy more in depth and he got it done in time. If he didn’t have to pay to store the boat and had better equipment to work on giant diesels he would have rebuilt them. There’s a lot of variables you seem to have missed in the video. There’s many reasons those clapped out diesels aren’t going back in
odysseyrider1 there’s a lot of variables you seem to not get also like taking 6 tons out of a bottom of a boat and replacing it with maybe 1500 to a ton. Big issues.
I disagree, last video I would’ve agreed but after seeing the condition of them now no way, both motors require a full rebuild and that would run probably $30k (nzd) each providing you can find the parts.
I still think diesel is the way to go but he’s gonna do what he wants to do lol
Chris I love the content but you still haven’t made ONE all out pass in your LS Lambo. If diesels aren’t your thing, pay someone to fix it correctly.

Just from reading the comments, with no boat or diesel experience, I've learnt so much...such as :

○those metal bits are most likely from the oil cooler
○ weight distribution plays a big role
○fuel tank size needs to be increased
○you can get away with just replacing the liner, gaskets , bearings.
○torque and reliability of a diesel out weighs horsepower of a petrol engine
○ increase in fuel price...
○needs to make contact with a naval architect
what else have I missed?
Typing this out, so I can go to one comment if I ever require this knowledge. ..
@Kentucky Hillboy Because he thinks he using his $$$ well because Texas Speed is providing the engines... He hasn't considered things like how do I add 3600lbs of fixed/static ballast in the same location as the engines were. Or how am I going to add enough fuel capacity to keep my range while still having the rest of the comforts of the boat. He hasn't thought about over the horizon reliability... because he thinks of it as a lake queen not a blue water capable vessel. Basically he's treating this like its no big deal if the engines fail because they were free, not thinking it could cost him and anyone on board their lives if they fail. He wants a play toy and this boat is not one. If he wants a play toy build something to blow the jet off Finnegan's jet boat, don't screw with a blue water craft this way. Not without consulting a naval architect / marine engineer and following their advice completely.
"needs to make contact with a naval architect"
Dude, he said in this video he is going to build a "really big boat" that is "his design" in 6 months in 2021/22. He clearly has never talked to a naval architect.
diesel is less flammable than gasoline, which is more meaningful on a boat.
@@TheM750 , I was talking in the manner of weight distribution for this boat. ..basically, the buoyancy. ..the placement of the tank, the way the waves will hit the boat with lighter engines. ..etc
@Kentucky Hillboy I get it, I am neither a mechanic or engineer, but I am really interested the sciences behind how and why things work the way they do. Especially, when it comes to vehicles of any kind. My point really is that his decisions are going to backfire, cost him a boat load of money, and could kill someone. Do I know the answers. Not really other than the marine engineers / naval architects choose a pair of heavy ass diesels for some reason, and I can only infer from my research that they did so for many different reasons. The Original Comment lists them out pretty well. They are all things that B is for build will have to figure out handle and manage. Or he could have ordered the parts to repair it and done the over hauls either himself for youtube content or taken them to a diesel shop where they would have been ready to drop back into the boat probably within 2 weeks. Shops generally have some really good people to track down and get parts. So that's not really an excuse. I don't know what the cost of a rebuild would be on those engines but I would say it's probably less than the cost to make the modifications to have a pair of heavily tuned engines, and the associated changes to ballast, electrical, fuel, cooling and props.
Ballast
I know I said this last time. The lighter engine means less ballast. Do your research on how much ballast/weight is needed to keep the boat upright. You don’t want to be in light waves and all the sudden the boat capsizes.
You might have to add lead or something in the bottom of the hull.
or he just could to the right thing to do and fix the diesel engine
Its a planning hull ,less weight more speed,you can feell the difference on anchor probably.

Boats have diesels for a reason chris I honestly think you're going to regret this decision
I feel the engine swap was already decided on long ago, he is doing this for views and to get people to watch the next episode etc. The time it takes for parts and shipping is just an excuse. A deal has been made previously with an engine provider. A shame the old diesels wont get a chance to power the boat again, they really are the best option.(20 + years in the Navy and Rail locomotive world working on all sizes of diesel engines. They are suited for these purposes). I still like to watch and see the success and failures of the projects they attempt. I give it 6 months at least before they get all the systems sorted in the boat powering under its own engines.
I agree with you, I still find it intersting to watch. Its something different. There is a reason why all heavy equipment, semis, trains, ships everything that has a lot of weight uses a diesel engine.
@gary Fox thast 20th century thinking. Overhere in Europe the days of the diesel engines are numbered, 2030 may be the last year they are roadlegal.. after that they are outlawed in most cities.
All the older cars, trucks and vans have already been hit with increasing environmental taxes, and because of that diesel sales have dropped significantly.
Same goes for agricultural/building equipment, the emissions regulations on those make them so much more expensive is becoming more economically viable to not buy diesels anymore.
(ps Im no diesel hater, just realistical. I recently scrapped my perfectly safe and reliable 1996 diesel van because of all the extra taxes and exclusion zones around here..)
Not to get too political, but this is one reason Europe will be a bunch of failed states begging the US to bail them out.
@@billsafreed3735 like the usa can afford that.. have you looked at the debt clock recently? if theres anybody saving us it probably will be China

You never get back what you put in a boat... Welcome to boat life... Personally I would stay with Diesel/ Also, boats have a "hull speed" put as much power as you want, you'll struggle to get past the hull speed of the hull design.

“Putting money into thIs boat that we’re never gonna get back”. . . . . . Too Right. Seems right on course with gas engines. This boat will be a hole in the water into which sponsor money will flow unhindered. Underestimating the issues with this conversion will be interesting to watch. The diesel crowd feels like it’ll be watching a train wreck.
I don't think it's "the diesel crowd" as much as "the marine crowd" expecting a train wreck. Marine-rated engines have a lot of factors to deal with that don't come into play (as much) with a land-based vehicle. For one example, removing weight as he's doing will change how high the boat floats on the water. That reduces drag, sure, but if that boat isn't a planing hull, he's asking to capsize and sink, especially since he's looking to move fast. Then there's the problem of gas fumes. Marine gas engines have flame arrestors all over air intakes and exhaust to prevent fire and explosion. Chris touched on a few other points himself in the previous video, as well. This will definitely be interesting to watch, and it could work; I just hope he doesn't manage to get himself or someone else killed in this experiment.
You need to give Mike Finnegan a call. As soon as possible. This is a disaster. Finnegan can help.
I've seen some stupid moves in my time, this tops them all... combined
Guessing you haven't heard about coast guard certification. None of the modifications you mention will ever be able to pass.
And when they inevitably fail and sink the boat or heaven forbid hurt someone, insurance isn't going to cover a cent of it because of that.
He could, even without just the switch will cost more then fixing the old engines. He hasn't figured out he will have to redesgin the boat due to new engines/gas tanks (since he can use the old ones) all the supporting mods. /it will be like the lambo with two gas engines on temp 5 gallon tanks for a quick speed lap with the boat (25% done but pretending it is nearly done) just to upload a video and pretend it is done and move on. Honestly, he lost his ass on the boat and is scared of admitting his 30k saving he sunk into that boat is gone and will have to pay 5k more just to hual/dump it. However, he should admit it and move onto the powerboat, much more realistic for his small brain and ls engine idea.
And I am pretty sure he has to do that USCG inspection because he is a monetized TH-camr and makes money from his channel and sponsorships, and gets the more rigorous one for commercial vessels...
look at the last time you tried to use LSX engines, cant even get that lambo to run properly and now youre trying to do the same with the boat
Hey Chris, love the channel. I think you really should save those LS engines for another project with Texas speed and wait to rebuild those engines. Remount them for proper ballast and get seatow to bring you to wet storage somewhere cheaper while you wait. I was so jealous when I saw that boat and pictured you taking it for long trips, overnighting, hell even taking it down to MX from where you are. Going with Gas motors are going to neuter that boat of everything that makes it amazing in my opinion. Just fix it the right way, keep diesel in it, and enjoy the adventure that comes with it. Put those two engines in some stupid speedboat build or something.

Everywhere is full of rubber, "very bizarre" I'm laughing my ass off! PLESE consult a marine mechanic if you are this unexperienced in marine engines and boats (because this isn't a yacht in my view)...
I dont know that I've ever seen a TH-cam comment section so united, this is hilarious!
Bringing the divided country back together one bad engine decision at a time. But, it is his boat and money.
Lol, I am a marine diesel mechanic, and I’m laughing at everything. The liners are probably leaking, through the o-rings. Also, those veins on the salt water impeller frequently go bad. Get jobs all the time like that.
Oh dude 100% I can't tell you how many I've done my first year at a full service shop. And the engine costing more than the boat is also a really common thing with boats like he's going to ruin this boat. Its designed to have big heavy engines astern of the mid point. That thing isn't gonna plane, handle, turn or even fuckin float right unless he puts 3000lbs of concrete in the rear. Dumb
Seriously how hard is it to replace a couple of liners? I’ve never worked on marine engines like this but have worked on industrial engines with wet liners and I don’t think it could be more simple. It’s easier than having the block bored out and honed when it reaches its service limit. How does he think he can replace a 14 liter engine with an ls?? This is like putting an LS into a semi and expecting it to haul a full load over a mountain pass because it has more horsepower lol.
I’ve never seen people get so pissed off for something that isn’t their project lol.
@@boostedsaleen6146 and yet here you are along with 250k+ views and over 3k comments. Clearly people don't care..... lol
The crank is also bad, seems like bearing material in the oil filter, who knows what they'd find at the bottom of the pan.
But putting a car motor into a boat is almost as bad of an idea as putting one in an airplane. At least the boat keeps floating.
If texas speed hasn't built a marine engine before you need to look elsewhere
Even if they have, they specialise in race engines. They’ll not be properly geared to make the right sort of engine.
They have not indeed, i commented it a few times already, he needs to go with marine engines, texas speed does not have that kind of experience! Going with joh boomer or nelson racing or something that has experience is just a better overall idea.
@@lildane9321 It sounds like you have 0 clue of what you are talking about.
Ernests Jansons No, not really, but I do know that gas engines are a bad idea for a boat this size.
Should have went with the Mercury Racing Marine SB4 engine
Why y’all gotta hate? Like cmon man just respect the dudes decision. I don’t think y’all realize that not all TH-camrs have a lot of money. You have to realize that even tho TH-cam is an okay source of income, with all the cars he has, this makes it harder on his pockets. I am sure he wanted to repair the Diesel engines but with the cost to keep the boat out of the water plus at the dock where he lives is just a lot for him. He made a decision based on what he felt is right. I completely respect his decision and I will continue to watch his amazing content.
LS engines are far from “peak of technology”.. Using petrol engines in a boat this size will be a disaster
B is for bad decisions for the sake of content!
1. those gas engines wont last in that boat
2. the value of the boat is going to decrease significantly because of the gas engine fuckery (for someone whos concerned with ROI this is counter intuitive for sure)
3. petrol + boat with engines its not designed for can quite possibly = big fire/ big explosion
4. BALLAST?!?!?! do you not respect marine engineers or???
5. did you really use reliability as an argument AGAINST diesels???
I could keep going but I wont... You lost me on this one. i was very much looking forward to some diesel content. instead we get ANOTHER LS swap somewhere it has absolutely no place being. Its the youtuber way I guess.
I'm kinda done being interested in this channel, tbh. Good luck, I guess I'm gone. 🖐️
For real. This guy is killing me. On nearly every build there are a bunch of people in the comments who actually know their shit and are telling him the proper thing to do and he ignores all of it.
@Lassi Kinnunen Raid: Shadow Legends. Paychecks for when questionable decisions fail epically.
Let him fail... lol 😂
hand over your wallet and labor and I'm sure you can have it your way. even though he fucking owns it
did anyone else start shouting pump impellor as soon as they found the blades
Immediately
I've watched enough delos and the like to recognise that straight away.
As soon as I saw the blue/black color of the water pump cover plate. Before they found the bits. I thought burned impeller. Someone ran the engine without raw water supply.
@@PappiH yup poor or no maintenance killed another one.
Yes , I did, I've seen the aftermath of a failed impeller, it ain't pretty.
The rubber parts are from your "Jabsco raw water pump impeller".
If this is the case, your engine may have overhead previously
B is for build: where we ask your opinion and completely ignore it
@@johngillon6969 i concur....
Yep
B is for Build needs to change the name to L is for LS Swap
"We LS swapped a hurican thats what we do"
We have yet to see that project run right at all so lets just move on the the next halfass project.
Yeah didn't that thing like catch fire or something not long after it was built. And I remember he took it to a show of some kind and it broke down on him and he had to spend half the time fixing it.
Two things:
1. You are seriously going to be missing the diesel torque. Good luck.
2. When you go to build your jet boat, talk to Mike Finnegan. A crossover video between you two would be awesome.
This could have been a great diesel engine rebuild series which I would have loved to see. We would have happily waited a month or more for parts and it would have cost alot less.
Even though you can get the parts next day from a number of online places. Including full overhaul kits with pistons, sleeves, bearings, gaskets etc. for less than $3000 for the pair of engines. What this is is a sponsorship deal from texas speed. and it is going to be a really lovely fireball that everyone can have a look at in about 3 months
And we've waited months already from the very first episode of the boat being introduced to the channel.
Yep. Same old same old for this channel now. As soon as he mentioned Texas Speed in a previous episode you just knew it was coming.
You had a base explosion due to being overheated i bet it blew the oil out the path of least resistance aka the water pump seal. You could have also been experiencing blowby because oil does not normally come out of the water pump. That hole in the water pump is a weep hole for the coolant seal not the oil seal
Water pumps that bolt into the oil space (area where oil is?) have a seal for the oil on one side and coolant on the other side the space is to let either of them excape if they fail. Water cooled motorcycles are like this on there water pump as they dont drive the water pump off a belt either.
I'm only staying subscribed because I can't wait for this to fail catastrophically.
This is the right decision for more TH-cam content. Rebuilding the Diesel engines would’ve been boring, he’s trying something different and I think it’s great !
He was going gas from day one, it was obvious. Kinda bummed, but also not my boat.
he'll realise his mistake
@@Mgiles1001 Sometimes we just gotta learn the hard way...
@@dolamyte that engine spins backwards aswell so would be a pain in the ass doing it to a ls
@@Mgiles1001 naw, just swap the leads on the starter so it spins the other way, problem solved 🤣
video title 2 days after the maiden voyage: CATASTROPHIC failure on the LS swapped Riva!!! No one saw this coming!!!
I'm so tired of LS swaps....
Super popular because it’s a great engine. But content wise it’s super played out and boring now.
Dude, literally all you had to do was get the engine rebuilt and then collab with a diesel channel for power mods
Honestly
Dude all you had to do was respect the man, get your own build if you want to see that...
@@cleatusjr6063 you right, I'll unsub. I don't wanna see this
@@cleatusjr6063 Homeboy he legit asked for opinions and then fucking went stevie wonder CaUse OH LS swAPEd ITALIAN YATCH coNteNt dumbass is gonna get stuck in the middle of the ocean and good for him SMH
Wasting your breath.
Previous owner knew this was about to happen. Sold it to the unknowing. Sad.
That is why you always get a survey before purchase by a reputable marine surveyor.
Yeah the bastard
