Don't use Carly, they are dodgy AF and have tons to hidden fees and will not refund.
@@kevinmatthews3282really wish I would’ve seen this prior to purchasing one. I was under the impression it was a one time fee to get the device and begin using the app. I’m an idiot for not reading the fine print or investigating further but I didn’t hear him say anything about a subscription in his ad nor did I see anything obvious on their website that stated that. Now I’m fucked cause they consider you buying the product a binding agreement that forfeits your right to a refund. @Bisforbuild please let us know all the details of the products you endorse on here. I’m out $70 now and I’m expecting to be charged more for a subscription if I ever want to use the device.
i would recommend a Promariner ProSafe FS Galvanic Isolator 30A for shore power connection
My comment got deleted for complaining about this product I think. They don’t tell you you have to subscribe to continue using it and then the company doesn’t accept returns when you figure out you’ve been shafted.
Some of this plug in devices say you got forty codes when really it's just one issue
As a former Mercury Marine employee, there is a very high probability that I made several components on these engines. Also, the oil is absolutely worth the money to use the specified Mercury Racing oil. Don't cheap out on your engines blood. Those oils were specifically designed bespoke for not only a Marine application...but for Mercury engines specifically.
He’ll never read this… he doesn’t care about doing anything the right way if it’s more expensive or harder… did you see his oil filter wrench?
Hi Chris,
I hope you’re doing well. I had a chance to review your pontoon designs, and I wanted to share some feedback on a couple of points that might help enhance the stability and performance of the structure.
Firstly, regarding the structural issue with the second deck, I noticed that you’ve done a great job over-engineering the beams to handle the expected load. The materials and strength of the beams are certainly not in question. However, I’ve observed that the bottom part of the truss has two points of attachment, which indeed provide excellent rigidity. The concern arises with the single point of attachment you’ve used for the second deck. While it’s not exactly a ball joint, this single point can potentially behave like one, allowing rotational movement that might lead to unwanted sway and instability, especially under dynamic loads.
To mitigate this, I would recommend adding a second attachment point for the truss on the second deck. This additional point of attachment will significantly enhance stability by preventing the rotational movement that a single point can permit. This change should provide a more robust and stable support system for the second deck, reducing deflection and improving overall structural integrity.
Regarding the water pool issue, I noticed something with the design that might be contributing to a fluid dynamics problem. The incorporation of a hot tub at the front of the pontoon has created a boxy frame at the bow. However, the termination of this section with wide angles in the sheet metal is creating an area of significantly low pressure behind the hot tub. This low-pressure zone is problematic, especially given its location at the front of the boat.
This low-pressure area can lead to instability, particularly since the boat has large engines that will generate substantial force. The shape at the front of the boat needs careful consideration because the forces generated by water can be quite significant and are not to be underestimated. The current design could potentially destabilize the boat, making it difficult to control at higher speeds or in turbulent water conditions.
To address this, I suggest redesigning the front section to ensure smoother water flow and reduce the creation of low-pressure zones. A more streamlined approach to the front design can help manage water flow more effectively, improving stability and performance. Incorporating flow control devices such as fins or strakes might also help in managing the water dynamics better.
I’ve tried to illustrate these issues with a diagram. If it’s helpful, I can email it to you for a clearer understanding.
I hope this feedback is helpful. Let me know if you have any questions or need further clarification on any of these points. Looking forward to seeing the final product!
Best regards,
Camilo
Sadly, he'll never actually admit he's wrong on any of this, like he always does. In two months you'd see a video titled "My $40,000 DIY Yacht Broke in Half!" or something
That's some great feedback Mr! I hope they read your comment carefully and take some notes and make some changed NOW so they don't have to do it twice😄
I thank you for your very clear and elaborate explanation👌
Very interesting insights
Extremely good comment! However this is the very definition of tldr. 😅
What about adding a half oval to the back of the hot tub. Would that reduce the low pressure problem?
29:40 Nothing is more permanent then a temporary fix that works.
Hey brother, you need to buy a set of ears that attach to your water hose and slide over the water intake vents on the lower unit. 90% of your cooling water goes in the vents on the lower unit and out the center of the propeller. The flush hose you are using is for running fresh water through the top half of your engine to clean out the salt water (with the engine off), and is not a sufficient cooling source. The water shooting out of the starboard side of the engine is an indicator letting you know your impeller is working properly. Thank you for all the awesome content.
Yes 100%! Don’t run off the flush port. Need to run with muffs
Yep was about to comment this same thing!!! Don’t run with that flushing port, best thing you can do it get a big bin or bucket and run the engine in that!
I disagree with this comment, although the addition of the "muffs" is fine, running off the flush port on a Verado is just fine if only for a couple minutes. I've been running Verado's for years (though they do build oil if idled to long), not all manufacturers recommend this but on these motors, its fine for a short period.
It was not a waste of 90 minutes to figure out how to install the lanyard switch, because you succeeded in the end. Perseverance! Well done!
You should absolutely be using "tinned" marine wire for ANYTHING on a boat.
I really enjoy the B is for BOAT content, and I hope you still plan on doing more content on the Riva yacht as well!
Yeah... That power cable is not long for this world. Well, to be fair... It's probably a high percentage of aluminum in the lat harbor freight junk.
knukonceptz ofc tinned copper power cables is what I used on my boat build.
I was just coming to say the same thing. Using harbor freight jumper cable wires really shows he knows nothing about boats. That wire is going to be corroded and causing issues in no time.
I also guarantee that insulation isn't rated for use in an engine compartment even if by some miracle it's truly 2GA copper.
Can’t believe you’re working in those crispy white fresh kicks. Brave.
I don't know if anyone pointed this out yet, but the upper water discharge on the starboard engine is very weak. Knowing you just replaced the impeller I would suspect a blockage somewhere. It's very worth looking into.
Often at the thermostat. I'd go ahead and replace both thermostats as well cause they're cheap and easy.
With how he was talking about how to replace the impeller, I wonder if he didn't put the new ones in the same direction as the old one, since that would cause the fins to be in the wrong direction, thus, weak stream.
@@tylershaw5528 bingo!
@@joeburns91 Replacing the thermostats is a good idea. However, I was just comparing the flow between the two. The port engine had a much stronger flow than the starboard engine.
@@tylershaw5528 Not a bad thought, but In my experience it doesn't matter which way the impeller is put in. It will always correct itself to the rotation of the shaft.
Epic project!! Can’t wait to see it finished
It will be fun to see if waves flex the thin frame structure enough for metal fatigue to set in. The pontoons might roll out from under it.
Galvanic corrosion is a serious thing I assure you. Engines should have an passive anode on them or a mercathode electronic system. You will need anodes for the pontoons, especially if this will be left in the water.
He said "we will have anodes on these anyway" why comment?
@@kiesh.exactly. What a nerd
Watch the yacht series, I am certain Chris is well aware of galvanic corrosion and anodes 🙈
Water cuffs, dry starts kill the water pump
You are correct but Usually running it for a couple seconds Usually won't hurt them as long as it's not longer than 1-3 seconds any longer then you are running the risk of damage
He has them on. 22:50.
@@TheBCninja he started at first without water but shut them down after a sec
@HackeryX
He started the boat engines with the old impellers, without water. Then, he put water into the system and started the engines with the new impellers.
It's fine.
@@kerryclark1926 He ran the water through the upper flush, not the lower unit. That is not fine. He needs to run muffs with the hose. The saltwater cleanout is not sufficient enough to run the engine.
16:12 famous last words my man
Ya know one should listen to a guy that can’t keep a bout alive for one year
This is a trash project that won't last long enough or be used long enough for corrosion to matter.
Any wiring that you use should be tinned to resist corrosion Marine grade wire will survive even fresh water boating better than plain copper.
Not a bad idea to change the lower unit lube and always check and make sure that fishing line doesn’t get between the prop and the lower unit !
With that much HP and weight definitely go stainless when you find the right pitch. Aluminum flex alot.
Be cautious about filling the hot tub with water from the Willamette River because it's been pretty toxic and unsanitary in the past
Did you change the oil in the foot
Pretty sure that you should not run engine using flush port as there is no water getting to the impellor that you just replaced, I damaged my 225 Yamaha doing this, You need the lower leg in a tank or use wet muffs. A dry impeller will last about 30 seconds.
Hope he at least checks the impellers again
Been there, done that... Last year I was working on my ignition system, testing timing advance was working, revved past 3k just for a test.
Collapsed garden hose, fried impeller... But ignored the smell.
Boy was that a long day at the lake, waiting for a tow boat😂
U can if it just at idle
the flush port is designed for engine off use only to flush the powerhead you dont get adequate water to the waterpump, you should use earmuffs with the blocker for the front screens when running these motors out of water
lol ok.. Chris go buy a Land Rover defender. If you think that galvanic corrosion isn’t that big of deal! My doors were paper thin, the seat box and gear box tunnel were just held together by the carpet, the floors were held together by the mats, and the rear tub arches and floor were just powdery salt!
20 years of British winter and salted roads dissolved half my car! when I restored it last year the only part that was salvaged was the roof and the windscreen frame! galvanic corrosion is real!
30:05 Once you fix that item temporarily, don't throw it away.Keep it around in the boat for a spare
I don’t know if you’ve covered it or not so don’t rip me if you did. But twins have directional spinning props and they spin opposite of each other. Double check to make sure you have that and the correct engine is on the correct side.
He did during the mounting process 😂👍
B is for Bumboclaat
Dont worry about Stainless props for this application. The performance benefit is going to be so slim you wont notice and its certainly not worth the cost difference. Those 4 blade props will do just fine.
Guys great episode of Lovett troubleshoot troubleshoot troubleshoot it always works out
Yes! Buy the inexpensive non-marinegrade cable for your boat! You will probably NOT be impacted by corrosion and electrical gremlins BEFORE you abandon the project due to all the design-faults you could have hindered by reading the comments 😂
Loving the boat series! Never been this early
“Big Mystery Box of Pain” is what I can’t bring myself to buy a boat. I’d feel like the guys in Dune that have to stick their hand in a box they know nothing about just to see if they can withstand pain. I can’t lol.
killer project, been subd since the start of the Z project. sorry to hear about the engagement bro hopefully you are doing well, know you have had a lot of crazy personnel shit going on, keep at it love watching along.
I'm loving all the boat content and I don't even care that much about boats. Hope we get plenty more episodes!
Yes you need to use boat oil. Long story short it has more additives in the oil. That what it’s 4 times the amount.
The oil is designed with those engines in mind. I would absolutely spend the extra money to ensure that I had oil formulated specifically for my engine. It would probably be just fine with regular oil of the same weight and viscosity but the fact that someone took the time to make an oil for that engine is enough for me
galvanic corrosion is a big deal when you introduce salt... look at aluminum rims in states that use salt to melt snow all year. if you are staying fresh water, you're way better off than if you are in salt water
Great episode
TESLA SWAP an OUTBOARD KINDLY as a side PROJECT 😊😊
Get a strap filter wrench. Does wonders on an oil change.
Good catch using the right fuel. Sounds like you got the beef.
How tall is the toon. My question is logistics. Build site to the port or where you can put in at. Basic bridge/overhead clearance is around 13' 6". This is going to be a bit interesting when the transport video gets made.
I was a bit disappointed when you first started this boat build as I wanted the Gallardo build but I’m really into it now, can’t wait to see it on the water.
that cybertruck part LOL
I like whatever you do brother! Inspiring me to do more! Thank you very much!
I do think you should run the recommended oil in your engines because these engines do have a high rpm at peak performance so you do want a good oil less friction
look at the mercury vessel vies bluetooth module for outboard monitoring.
I know with my boat you’re not supposed to turn on the water until the engine is started and you should turn off the water before turning off the water. It keeps water from the exhaust from entering the cylinders.
Next time 2 2' 2×4 and attach them to a table wide enough to slide the lower end into it next time.
“Our river is very deep” lol 😂
Did I miss it or was the gear oil never refilled?
Aluminum props flex but if you hit something with them most of the time you just take out the prop. Stainless not so much
Oscar needs a freaking raise. This guy is the man. Nothing more to say
I tried regular engine oil once in my big block and she didn’t like it! factory oil is best. I have owned the same boat for over 20 years and have been a aircraft mechanic over 28 years.
makes a tool for the fuel filter houseing cap but doesent have a common oil filter strap wrench and then uses old contaminated gas in a unmarked can ?
Using that jumper cable is really questionable! The insulation on those are definitely not rated for permanent installation within an engine bay.
This Pot / Yatoon is going to be Epic!
Hogwash maybe if Valvoline makes a replacement it is better and cheaper . If not maybe not .
B is for boat!
@bisforbuild collab! With @BornAgainBoating! Much has a great channel and let the expert do it correctly and teach you how to service!
Are you going to use marine grade wire? The tin plated wire? Don't use the jump cable! Not a good place to cheep out on!
12 year marine mechanic. Definitely will ruin the impeller fast if you run it on the flush hookup and it would be the FSM (fuel supply module) and they do fail but definitely wouldn’t mess with them until they do. Also mercury designates 25-50 specifically for the verado.
still curious how the boat is going to float with the hot tub on the front
So many things, I can’t wait to see this probable spectacular fail. The engineering seems off to me I would love to be surprised. Cool idea but not sure it will get there. Subscribed to see.
The old two stroke engines were so much simpler and better.
Are you concerned with dissimilar metal corrosion? I think in a previous video you attached steel to aluminum for the upper structure.
Perfect test bed for toroidal prop experiments.
Awesome project !
I have an oil filter wrench for you. I’m in Portland.
If under warranty, I'd use the recommended oil. If not, use high quality oil of the right viscosity, any brand.
Lets go back to building cool stuff
To make it easier to cope with boat expenses i use the term "boatmoney". 1 boatmoney = 100 dollars.
i think you are going to realize that having the pontoons extending beyond the mounting point of the engines is a bad idea... if you do high speed turns or do faster acceleration those 2 are gonna take so much load. you could just have free hanging bridges going out no need for a pontoon under. If the engine would be weaker it would not be an issue but since thats 500hp.. ahh idk
Man these engines sound great is this engine in any car yet or that I don't know of? Anyone do a swop yet?
Filter pliers rule. Easy off stuck filters
I thought you were supposed to make sure water was running through it before you start it?
Chris with the freaky ahh scream 😂
Look that you a right turning outboard engine and left turning engine an that they taking water from the outside than you have more power
Remember that the engines are supposed to rotate opposite from each other
Get a stainless steel prop!!
The University of TH-cam!
If you enjoy the thrill of lighting money on fire and watching it burn then paying the premium for "Mercury Racing" oil is the only choice.
Please paint those engines, they look nasty 😂
I was told they have marine grade shrink wrap at harbor freight. Fyi
RIP the new impellers
Outstanding
All these simps worried about Chelsea 😂
Sometimes I think we need a secondary channel called "O is for Oscar" There's nothing he can't do!!!
Did he just say he was going to put the fuel tanks on the back corners..? Where boats get hit all the time?
Oil pressure alarm was the beep
I loved the cybertruck roast we got out of nowhere
Those impellers are screaming get some cuffs
Change the gear lube?? Just didn’t see that
Lol at Chris's reaction to the neighbours cybertruck 😂
That was fucking stupid.
Lowers in neutral
Don’t think u can put pressure treated board directly on the aluminum it will cause it to eat the aluminum clean out check on that I’m not 100% sure but check on it
I know what went wrong.... something about pissing into the wind and liking it.
Dude, Twin Verado's, Italian sports cars, and you were at Harbor Freight. Obviously you're not living on Blue Box and bologna (hell yea! happy for ya, for real, not a success hater) and you're filter wrench is a screwdriver hammered through the side? Bruh, they're probably hanging in the check out line where candy bars and gum would normally be. But then again, when you hit the throttles and rip the heads off those tubes and they sink, does it really matter? :D
I used the net bitd, 01' and rebuilt a Bass Tracker. Stripped it, drilled out rivets, altered it on saw horses. Repowered it with an online sale page, got a motor out of Canada from a fly-in fishing outfitter. New controls, steering gear, gauges - without the internet? neva happen. Today it's cake and way more info than when I did it. And that boat is still awesome today. Most amazing part of it, was painting it. To this day, looks like I painted last week, Imron - holy shit expensive but wow!. They don't make products like that today.
No spark plugs?
Those things need turbos!
So you're going to want to use the Mercury Racing Oil because of deez nuts
What Nikes you wearing?
