I don't think everyone realizes how big and heavy this boat really is! Its awesome how nice everything is working together and I'm dying to see this boat when it had the original 4.3 V6 in it! The 5.3 literally transformed this boat into something special. You have got to share the update when you install the bigger flexfuel injectors.
In the bowrider world, this boat is actually not big (this is a pretty small vessel) or heavy. This boat is light, like light-light. In fact, a bayliner/maxum is of the lightest bowriders out there, purely due to thinner (and fewer) materials. I don't say that to bash it, but to rather make a point that the power/weight ratio of this boat would be better than something more substantial (a FourWinns, Regal, Cobalt etc for instance). When you're looking for speed, power/weight is what you want. So not a 'bad' decision in that regard. But an odd one given the relatively lower "perceived value" of bayliner/maxum. I guess that might add to the "cool factor" though.
@@savage6394 True but there's 0 way that's flying by a 200k powerboat lol! (ok I guess it depends on the TYPE of boat lol). It's a cool swap sure, but, lots of 70-80mph boats out there every day at the lake. They'll definitely be King of the family bowrider class though :)
Reality is there are actually not that many 70-80mph boats out there. And very few 80+ mph boats out there. Depends on the lake tho, up where I'm at nothing beat me when I was a 68mph boat, and nothing could touch me after the build when it was an 83mph boat!
@@yoster77 I think he meant compared to a car on the size aspect. but About the power to weight its not sooo important on a boat that size if your just a normal boater you really want the torque that a marine engine is designed to put out but yes taking it to that extreme with the 5.3 tuned LS its bound to be quick. I've got a cuddy cabin boat similar size with the vortex 4.3 and she does 44mph which for boat standards is quick! so 70+ mph in that is ridiculous.
I love the sound of that engine at idle and on the fly by runs. 70 m.p.h. ain’t too shabby. Quite the step up from the old 4.3 V6 for sure. Nice swap.👍👍🇨🇦
keep it in the water if you junp waves or run an alpha like an offshore race boat thats when they fail ...from loading and unloading the prop ... go easy on holeshots also .
@@mken4740 3000 lb hull is alot of stress with 500 hp i have been racing and building offshore boats and outboard drag boats for 25 years i have wrecked more alpha and bravo drives from load stress and shock than you will ever see.
A client of mine gave me a Yamaha AR230 jet boat. Like the one in the video with that group. Both MR1 engines are about gone. There is TONS of open room for a LS swap in the engine compartment! Tuff part is getting creative with a single jet pump outlet.
That's a pretty cool swap with a solid engine without adding a ton of weight. 70mph with an I/O is impressive. I'd stay away from the E85 though if you plan on using it regularly. You might get a few more HP but with a big loss on fuel economy, and you'll burn through fuel like a jet ski. I did a 6 month experiment with E85 in my Yukon when gas prices were almost $7.00 per gallon for premium and E85 cost 30% less. My overall cost per mile was still a little better on the premium just because my fuel efficiency dropped by roughly the same % as my cost for fuel did. So it wound up being a wash and I had to fill up more often and I didn't get any noticeable performance gains.
@@sirsneakybeaky The computer systems in FFV's are already designed to make their own performance adjustments based on sensing the amount of ethanol in the fuel being used, so you don't really need to tune for it. They will generally get a few more hp and some torque, which makes towing easier. People who do specifically tune for using E85 are generally trying to achieve max power in custom-built setups, not efficiency.
7:50 - That thing sounds HELLA! I had a Crownline 210 CCR with the lil cabin on it.. It only had a 5.0 in it. I really wanted to take a fully built LS and throw it in there. I would be interested to see how you ran your exhaust on this... So its above water .
This is so cool. What a sleeper. I'll bet it is going to surprise a lot of boaters out there. I've always wanted to find a clean old '60s runabout and do a swap like this. What lake are you on?
Awesome boat, if you’d be willing to shoot me a couple tips on what it takes to get it done I would appreciate it, I’m in the process of swapping my boat over to an LS and any advice and suggestions would for sure help me out !
Holly crap! That pretty awsome but I can’t believe the alpha1 out drive holding up. He should look into swapping to the bravo out drive that handle way more horse power and torq.
Wow. I have 96 Maxum 19’ and swapped the 4.3 for a 5.7. Captains call with through hull. It’s fast enough but of course I’m looking at vortec head swap. Not sure how it will run with that compression though… anyways, I love what you did!
Run 93 octane. An flat top pistons should be ok. Very popular swap. Offshore powerboats has a lot of info on this. Will need intake manifold change as well. If your running a merc. Also look at a HEI swap as well an did the the coil. Can be done on an OMC but takes a bit more work.
Great tuner one if the best going from a 4.3 what had to be changed on the back end of the motor were hooks to drive did you have to move the mounts up some. Been wanting to do this if motor ever goes did you go with marine cam
That boat is awesome! I have a 20' searay open bow with the 4.3 carb merc. I am now gonna do a 5.3 or 6.2 fuel injected swap with a truck norris cam after seeing this. Only problem is the alpha outdrive is typically only good for 350hp "ish". I will find out....
Love the build, what a sleeper. I have a 6.0LS swapped 1981 glastron cvx18 and am in the final stages of restoration / final touches. What are the cam specs, any issues with reversion? Dry or wet exhaust? I am running a BTR stage 2 truck cam Who makes that 25P prop? I have a 21P with that same Alpha gen2 drive and it seems like it could use alot more prop
Hey man love the swap!! Just a heads up I think your exhaust riser run is too short for the cam you have in there. You might be reverting water back into your exhaust when running. Just be careful.
Ive got a stovebolt 6 in my boat. Was thinking of going v8, BUT, ended up finding a 68 firebird sprint motor, PMD OHC. Boats got a 165 hp, the pmd is rated for 215. In time...
Remember back in the day a good friend of ours supercharged the stock 6.2 truck engine and did some stuff with the fuel and tuning in his 23ft Sea Ray and that thing would run about 70-75 at almost 5k lbs, so I just KNOW that boats fast a fk.
I am planning on changing my 5.0 Mercruiser with an 2004 LS6 all aluminum. Any advice and tips are welcome. I am building a “Sleeper Sea Ray 200 Select.”
That alpha one out drive is getting tested and is about at or over what it's designed to handle as far as HP goes for sure and upgrading is certainly not an easy task I don't think you can just bolt a bravo one on there but it's really what it needs they handle big block power maybe with real good maintenance synthetic oil the alpha might live for a good while that boat is badass as well you know damn that's awsome
Does Holley have the shift interrupt switch for the alpha drive when going in and out of gear. I ended up doing a bad ass 383 Stroker sbc 8 years ago instead of an LS1 Stroker for that reason. You’ve got me thinking! :)
Yes I'm away I watched but there more to them then that. How he got the water to flow how the outlets are made. I'm telling you if you make a video it will get views lol
@travtech1 Quick question, are you just using this raw water pump from the alpha drive to feed the engine water, or did you add a sea pump to the front of the motor, or are you using both methods?
Nice build. I appreciate the cockpit interior and overall appearance in addition to a respectable 70 mph ls swap. Looks like ca registration. What lake was that.
I have a 6.0 im about to put in. What are the specs on this cam? I want top end speed without water coming back especially at idle. My exhast are wet/dry out of the lower side. Do you travel to tune? Im located in Ft. Myer Florida
The new LV3 V6s in the 2014+ trucks are based on LS instead of gen 1/2 350 chevy architecture. As such, stock for stock they make as much power as an NNBS (07-13) 5.3. Richard Holdener tested one with a single big turbo and stage 2 cams and it make over 700lb-ft safely but ran out of injector overhead before even 4500rpm with that much boost. A normal LS swap is cool, but replacing the old 4.3 with a better 4.3 would've been more unique. Even just the stage 2 cam and full bolt-ons bring the LV3 up to 375HP.
@@travtech1 The point is they have much nicer heads and higher potential. There should be DI block-offs and port injection intake manifolds already available.
what was maximum wide open rpm?? anything more than 5000 for extended runs will heat that alpha up too much... ..you need drive cooler and watch the rpm and she may survive.
Wired it to spare input on holley set it up to trigger 2 step limiter at 400rpm. Gets it to dip rpm to come out of gear smooth but not stall out the engine
At about the 5min mark, you mentioned that a marine Tstat needs to be on the outlet side, but the LS is on the inlet side. Can you elaborate, because I can't figure out why it would matter. I had planned to use stock LS pump/Tstat with my closed cooling system.
It sounds like the gear ratio is off from the actual standard sets .maybe try out the upper gear set of 1:50:1 with the lower of 17/28 for a bit more speed 😈😏😎🙊
I have a factory LS 5.3 gen v that’s in my boat. It’s a Volvo penta that they de-tune to 300 hp. I wonder if I could unlock my ecu and have the power pumped up?
When you add the nitrous, don’t for get to let us know what the dimensions and type of prop you’re running. “A 25 pitch stainless 3 blade” is pretty generic. What’s the diameter, brand, and style? Different props will affect your boat differently and you can gain 3-5mph just in a style change.
@@Dardantuned for the next video can you cover; motor mounts, fuel pickup, add ethanol content sensor, raw water pump, closed water cooling setup, the oil cooler how it's plumed, oil filter stock or remote position, show the wet exhaust setup! tuning side, how to save the outdrive!
Michigan wheel xhs 14.25 dia 25p 3 blade Motor mounts are steel plates 3/8 thick that adapt the 3 bolt mounts from v6 to the 4 bolt ls block. Raw water pump is stock inside the out drive pushes water thru p/s cooler then oil cooler then to exchanger then to headers out the exhaust exits. Steam ports on engine plumb back to water pump outlet. Has 170 deg t stat.
Oil filter is in stock location with sandwich plate to feed to cooler. I added to the truck oil pan sump by welding a bigger box to it to add capacity it holds 11 quarts of oil now.

That boat sounds badass and looks like it handles speed very well for a hull that did 45mph max on the original 262?
Sick!
Bad ass ❤
I have a factory LS 5.3 gen v that’s in my boat. It’s a Volvo penta that they de-tune to 300 hp. I wonder if I could unlock my ecu and have the power pumped up?
Is it running gm ecu?
@@Dardantuned I believe it is but Volvo puts there own sticker and part number on it
And the fuel pump?
Quick question when you’re running 70 mile an hour what is your RPMs at and how long can it hold it there?
Its like 6200 i think
6k
Looking to dude the same to my boat if there there is a break down for the build or if you can get in touch with me that would be very appreciated
Do you have any problems with high temps with intake air since your right above the motor and being closed in the engine bay?
Iats don’t really get over 120
When you add the nitrous, don’t for get to let us know what the dimensions and type of prop you’re running. “A 25 pitch stainless 3 blade” is pretty generic. What’s the diameter, brand, and style? Different props will affect your boat differently and you can gain 3-5mph just in a style change.
I’ll have all that info on the next vid! Anything else you guys want to know respond with comments
@@Dardantuned for the next video can you cover; motor mounts, fuel pickup, add ethanol content sensor, raw water pump, closed water cooling setup, the oil cooler how it's plumed, oil filter stock or remote position, show the wet exhaust setup!
tuning side, how to save the outdrive!
Michigan wheel xhs 14.25 dia 25p 3 blade
Motor mounts are steel plates 3/8 thick that adapt the 3 bolt mounts from v6 to the 4 bolt ls block.
Raw water pump is stock inside the out drive pushes water thru p/s cooler then oil cooler then to exchanger then to headers out the exhaust exits. Steam ports on engine plumb back to water pump outlet. Has 170 deg t stat.
Oil filter is in stock location with sandwich plate to feed to cooler. I added to the truck oil pan sump by welding a bigger box to it to add capacity it holds 11 quarts of oil now.
