I was thinking more about reliability, low-end torque, and fuel consumption, but that's a whole other level of issue. With such a big boat, It just seemed like a bad idea from the start.

Honestly, i haven't watched in a while. But going back to the boat is different from the 10 million other car channels on utube. So personally, i jazzed to see you work on the boat.

A lot of talk about fixing the diesel's or buying new ones, but I'd love to see the cost breakdown on those motors plus all the fab work you had to do. It really can't be that much more expensive to just have done it right the first time.
Main issue with using gas motors in a boat this size is the fuel consumption for what he saved with these he'll pay for in fuel any experienced boat knows this thats why once you reach around 40 feet you rarely see gas engines
Recommendation for the Ocean water heat exchanger, get a plastic container that works and soak the whole thing in muriatic acid, get all the grime out of there so you start fresh! Muriatic acid is hardcore stuff so use proper ventilation and do not touch it with bare skin.
You got that backwards, Chris. Horsepower is a calculation of Torque and RPM. Torque x RPM / 5250. That's why on a dyno curve the 2 numbers always crossover at 5250 rpms
If the equation for horsepower is: Hp = (Tq * RPM) / 5250, then mathematically, you can isolate the equation for Torque as: Tq = (5250 * Hp) / RPM If I'm missing contextual understanding as to why you'd only use one calculation and not the other, I apologize.

You build and work on all kinds of cool things, but the boat is my favorite so far. Its so different and you guys are doing everything live and just figuring things out as you go.

Gonna be a lot fun for a little bit. This is going to have a predictable end but I am going to enjoy watching. I’d love to see DeBoss garage do something like this with some old school bus engines.
bruh, how many miles do nascar engines get at wide open throttle?? How many miles do trophy trucks get out of their engines? Both of these classes of racing put down 900hp with big v8's for 2000+ miles before rebuilds. If he runs these engines not at wide open throttle he can increase the life of them. If he got the gearing correct, and can get the prop correct, theres no reason he cant use these engines for a few years with how few hours he'll really put on them per year. obviously gearing and prop selection has to match. Lots of factors to get right or wrong, but texas speed builds good engines and these are running at half the power they were designed for. Cleetus runs similar engines pushing 2000hp and he makes them last all year in his drag car. either way it'll be good for us to watch.
@@user-zj2mb3sp3x which car from cleetus has been running 2000hp for years? Ruby and Leroy make low 1000's. The el camino will be able to reach 2000hp but i doubt that they'll max it out all the time.
@@user-zj2mb3sp3x I’m not disagreeing at all! 100% on board for this, I’m just saying that Diesel engines meant for maritime applications last a lot longer.

@@joshkiej6601 the fact you can call these random dorks by their names and know all their horsepowers by heart is disgusting. Find something better to do nerd.
Toured Texas speeds so back in November. I was able to see the work being done to these motors, amazing shop, amazing guys. If you've never been and are in the area please stop by.
if the gearing in the tyranny is right so that they can cruise comfortably at say 30 mph while the engines maintain only say 4500 rpm, then they will work out ok for a while. But if they try to run the engines rpm tapped out, they will last like a week
I don't think power and performance is the issue here. Its MPG. These engines will eat fuel. Its the reason why you don't see Semis using gas engines. This boat will not have the range it did before.
I love engines so, to see different applications, having worked BOTH boats, and cars, I LOVE this! Had my own engine shop, since retired, but I worked in a shipyard too, I have worked from making 15 ft bass boats, to offshore supply rigs, over 100 ft long with anything from I/O, to turbine engines along with EMD engines (locomotive type diesel engines). I loved it all! Even worked refitting some notable boats, like Jacques Cousteau;s old boat. I will keep on watching, regardless WHAT you build!
I lived on a 65 foot boat for 7 years that traveled in salt and fresh water. It was powered by twin mercruiser 454s, although it had big trs stern drives it did just fine, it was a planing hull and at planing speed it burned 40 gal per hour. However one day one of our aluminum tanks sprung a pinhole leak, we found out only after it began to smell like gas in the cabin very dangerous, engine room blowers helped but didn’t keep fumes out of main cabin, any spark from water heater, oven, etc. and boom. Had to drain starboard tank and seal with epoxy until replacement. Of course tank remained empty.
I love this boat project. I just replaced the fuel pump in our families 24ft with a Mercruiser MPI 350 last summer. It runs great now. It is cool to see a project like this come together.
Really happy to see this back on the channel , been waiting to see how it turns out , keep moving on the project and get the boat running . As stated already . Bilge blowers to get fresh air in and keep it cleared out of any fumes .
You guys are incredible young men....Amazing! Love your work...you always make it come out right...I am an old guy who never saw guys back in my time as capable as you three are! Good luck on the boat...wish you nothing but the best!
You have done a nice job sourcing marine stuff, but make sure the alternators and starter as well as all other elwcteonics are approved for use in a marine application. They make special electrical parts that are shielded to minimize the risk of sparks specifically for marine application.
@@BrianNavalinsky What are you talking about? There are boats for sale right now that you can buy that are 90 foot mega yacht that are powered by inboard gas engines. Mick is right this is not the first time this has been done.
@@mcgee6177 And you rebuild at 200 hours. You are talking to the wrong guy. I owned a boatyard for ten years, surveyed boats internationally for another twenty and have owned Cigarettes and surveyed Rivas. What the man is doing is fine if he wants huge fuel bills and low engine life. I have liked my engine rebuilders, but I didn't want them as mates. This guy will be lucky to get 100 hours out of a 454 ls in a 13 ton boat with a performance deep vee hull. My 35 Cafe Racer had twin, blueprinted, fully forged, marinized 454's but weighed only 5 tons.
Oscar is a treasure. I wish I had a personal fabricator lol make sure you make some sort of drip tray system underneath so that when you do an oil change on it its not sitting on the bottom of the boat. Maybe a tray system that isn't level and it runs somewhere you can remove the oil.
Yeah... he was joking about his mistake but, he probably should have said "even accidentally protecting..." people misunderstand jokes like that all the time. But meh.
looks like a nice solution. we use a car derived/marinised engine in our boat and it makes spares super simple, and without the "marine" additional price tags...
Most smaller ribs, especially the ones used as tenders, all run on gas. Also, he clearly isn't going to take this thing out into the middle of the ocean. And all of that is assuming that for some reason a senior software engineer is unable to calculate how much fuel he needs when he goes somewhere. I'm a little over all these negative comments. The guy clearly isn't an idiot.
@@jwalster9412 No worries. I might've mistaken your comment for being more negative than it was. A RIB is basically one of those smaller boats with the inflatable tubes around them. You often see them as small dinghies hanging off the back of larger boats. The outboard motors on those are almost always gasoline engines until you get to the pretty high powered ones. With the small dinghies the owners often have one or two jerry cans on board with a couple of gallons of gasoline in them. It won't run those two LSX engines for long, but it'll get them to shore of they run out.
@@jwalster9412 You're right. Basically all boats this size with inboards run Diesel engines. Everything bigger than this uses big Diesel engines. Going with gas on a boat this size seems like a huge mistake to me. Diesels have way better low end torque, a better powerband for marine use, better efficiency and are a lot more reliable. IIRC basically everyone was telling him this when he announced he was going to repower it but I guess he didn't listen.
@@go2yanks plenty of boats this size running gas outboards these days, a high end gas inboard not much different. Really not a big deal if done properly, the majority of pleasure boats run on gas. He's using it inshore, he'll be fine.
Oscar's fabrication skills are beyond compare. He did a great job on the mounting. Those engines are beautiful monsters. Texas Speed does beautiful work. Can't wait to see them in place.
Smart pick on those engines. You decided to get the best engine tried and true, without bringing them to their limits, their gonna run smooth & cool with enough torque. 👍🏻
@@MaximKilligan yes, in the same way that large motor boats running petrol exist. But we all know that diesel engines are the best engine for the application
I know this is a surprise to everyone, since it's never happened before, but Oscar did a great job on that jig... :-) Also, those motors look like they could use an oil filter relocation kit. It would be much easier to service.
I personally would have rebuilt those diesels. HOWEVER, plenty of boats are equipped with twin gas engines for cruising. They’re cheaper to replace, and cleaner running when putting around on a booze cruise, which is the primary purpose of an express cruiser like this. They don’t handle extended range cruising as well as diesel, but this ain’t a trawler. Good luck Chris.
You need to vent the engine compartment with intake and exhaust FANS and Ignition proof Battery Switches, Chargers, EVERYTHING! Install your inverter in the cabin while you're at it!
For starters . 1. Check if your boat can handle that much power , would be bad if your shaft cracks your boat 2. Don't forget to paint the engine , it will last much less if you hold it bare metal 3. Make sure that you have good ventilation at the engine cabinet , so that the fumes don't blow.
So many people still don't realize the real reason he went with these LS engines is VIEWS, his vehicles are a big part of this, and going with something radical for the boat, is far more interesting than something regular, doesn't matter if the end result is good or bad
Correct....its all about the views...we will see one, may two videos of the boat in action and then it will be left to rot away like all the other b is for bodged projects.
Interesting project and I think it's marvelous challenge to make it fully operational with gas engines. Keep at it! Hope she is on the open waters cruising soon.
To make all that torque, they are going to be eating gas like crazy. Yes, gas can make torque, but diesel does it more efficiently. I am super interested to see how this comes out.
Glad to see the boat back. Can't wait for another trip out into the ocean. Don't know what you'd do for fuel but with turbskis probably could set an LS record for US to Japan.
I hope you get your 454 LSX in and working safely including venting, when you pull away from the dock with your boat done, slap your back side, meaning KMA to all your distractors
@@douglasm3310 its a good engine for a smaller boat, but when your talking large boats like he has there is a reason that almost all of them are diesle
Oh and by the way, several boats come stock with 454’s (7.4L) and newer ones even come with 8.1 L engines, all gas. Not unusual at all for a 36-40 footer on plane
Oscar is an absolute weapon every time I was him do this, I am a machinist by trade so I can appreciate most of what he does and he still blows me away
I am surprisingly impressed on the engine build. Someone realized you need to cam the engine for marine duty, a “street” cam would not cut it. Good job.
Ooooh man im excited for this. Perfect timing because I actually forgot about this project but was reminded of it last episode when you revisited the boat hahah. Looking forward to it!
"Were dealing with boats, so we wanted to get the most torque we could" *ditches the diesel engines and buys gasoline v8s..* didn't even have us in the first half chief.
@@rsdna9698 as they say buy once, cry once. A well built marine diesel will outlive 20 of those lsx v8, produce less heat in the engine room, and be significantly better on fuel and reliability costs.

Going with gas on a boat this size seems like a huge mistake to me. Diesels have way better low end torque, a better powerband for marine use, better efficiency and are a lot more reliable. IIRC basically everyone was telling him this when he announced he was going to repower it but I guess he didn't listen.
@@go2yanks plenty of boats this size running gas outboards these days, a high end gas inboard not much different. Really not a big deal if done properly, the majority of pleasure boats run on gas. He's using it inshore, he'll be fine.
Oscar's fabrication skills are beyond compare. He did a great job on the mounting. Those engines are beautiful monsters. Texas Speed does beautiful work. Can't wait to see them in place.
I have my thoughts but will wait to see how they actually perform but, what I think is more importantl, how long they last....
Long.
@@ernestsjansons6705 not as long as those diesels though
If funny that he talks about reliability, but chose to go with gas over diesel...
@@davidfernandez3554 it’s funny you talk about either when you’re likely riding a bike to school
@@桜島芽衣さくらじまめい how sweet, how many custom built motors have you got from Texas speed and what was their lifespan. Don’t comment on what you don’t have
I love the jumps back and forth to the boat and car! Refreshing to see multi-projects going on at the same time!
I'm so glad to finally get an update. I love an average guy showing how he will replace the engines in his yacht.
Hail king Oscar the 1st. Not just talent but ability and finesse. Love your work Big O! You are second to none.
So glad for some boat contant! I wanna see how this comes out! :)
CANT WAIT! I've been waiting all winter long to see these engines come to life in this boat. This is gonna be AWESOME !
I live so close to you glad to see the progress on the boat been waiting for it
Im in PDX area too.
Smart pick on those engines. You decided to get the best engine tried and true, without bringing them to their limits, their gonna run smooth & cool with enough torque. 👍🏻
Wow. engines producing 650 ft/lbs replacing engines that made 2300 ft/lbs of torque. Each. This should be interesting.
@@Scott-gc4pt IT WILL BE SLOWER BY FAR AND PUT 10 PEOPLE ON IT WITH FULL FUEL TANKS AND WATER TANKS ...LOL IT WONT EVEN GET OUT OF ITS OWN WAY....LOL
Thank you for the update! I'm digging the boat build more than anything else!
Next project, buy a semi truck, find it has a blown engine and decide to install a LS because a big Diesel engine is obviously not the right choice
You do realise that semi trucks running on petrol exist?
@@MaximKilligan yes, in the same way that large motor boats running petrol exist. But we all know that diesel engines are the best engine for the application
I know this is a surprise to everyone, since it's never happened before, but Oscar did a great job on that jig...
:-)
Also, those motors look like they could use an oil filter relocation kit. It would be much easier to service.
Im excited for boat and jumacan content!! You guys rock!!
I personally would have rebuilt those diesels. HOWEVER, plenty of boats are equipped with twin gas engines for cruising. They’re cheaper to replace, and cleaner running when putting around on a booze cruise, which is the primary purpose of an express cruiser like this. They don’t handle extended range cruising as well as diesel, but this ain’t a trawler. Good luck Chris.
Love the boat episodes. I love my diesels. But I’m excited for this. You do you.
You should use ATF for drilling and cutting. PB blaster makes the bit slip while ATF bites and cuts faster.
I feel like at least one of his builds should be sponsored by Harbor Freight
You need to vent the engine compartment with intake and exhaust FANS and Ignition proof Battery Switches, Chargers, EVERYTHING! Install your inverter in the cabin while you're at it!
Man we love all your vids / builds! We as a group would love to see that boat on the water again to seek redemption.
Back on Boat. Love this project! Seems like alot of fun to work on.
Oscar is so talented !! Training and experience show through in aces !!
For starters .
1. Check if your boat can handle that much power , would be bad if your shaft cracks your boat
2. Don't forget to paint the engine , it will last much less if you hold it bare metal
3. Make sure that you have good ventilation at the engine cabinet , so that the fumes don't blow.
Glad to see you back on the boat.
So many people still don't realize the real reason he went with these LS engines is VIEWS, his vehicles are a big part of this, and going with something radical for the boat, is far more interesting than something regular, doesn't matter if the end result is good or bad
Correct....its all about the views...we will see one, may two videos of the boat in action and then it will be left to rot away like all the other b is for bodged projects.
😂😂😂 now don't forget to travel with Gas barrels
Rite
Interesting project and I think it's marvelous challenge to make it fully operational with gas engines. Keep at it!
Hope she is on the open waters cruising soon.
Put the diesel engine in the your camaro with crazy supercharger. That would be crazy cool 😎. Good luck in your projects
See Westen Champlain!
Well done Oscar! Looks great. He is definitely the star of this video!
To make all that torque, they are going to be eating gas like crazy. Yes, gas can make torque, but diesel does it more efficiently. I am super interested to see how this comes out.
“Super interested to see how this comes out”, you know we’re all here for the same reason 😜
Wicked I'm very cool that we get to swap around what vlogs we see all are Awesome Content thank you
I stay subscribed for the boat content.
Glad to see the boat back. Can't wait for another trip out into the ocean. Don't know what you'd do for fuel but with turbskis probably could set an LS record for US to Japan.
That sounds good to me ,I like the mix Chris🇬🇧
I hope you get your 454 LSX in and working safely including venting, when you pull away from the dock with your boat done, slap your back side, meaning KMA to all your distractors
He's gonna blow em within the first 4 trips.... fight me🗣
I’ll take that action! 1$ bet?
Why? The ls is a popular boat engine.
he's gonna blow a gasket when he sees how much fuel those two will consume.
@@douglasm3310 its a good engine for a smaller boat, but when your talking large boats like he has there is a reason that almost all of them are diesle
he'll make it out of the harbor just before he sends a piston through the transom and sinks...
Oh and by the way, several boats come stock with 454’s (7.4L) and newer ones even come with 8.1 L engines, all gas. Not unusual at all for a 36-40 footer on plane
Oh yeah the boat! "We can't let the boat sit any longer" means the storage fees are killing me. Sorry.
Oscar does amazing work, the guy is truly talented. A real artist and he doe such neat work.
B is for boat! Woohooo I can’t wait to start watching these again.
love to see another boat epside, keep going ,looking forward to the next boat episode, really like your boat and amazing engine build
Thanks for these vids. Would be handy if you had a B is for Boat playlist so not to miss any of the boat vids
I was really happy for the Single seater concept
Damn, that's some bad ass fab work with that mount. It was super cool to see built
To be reasonable, at least when it's "finished" the engines could be repurposed for a future build lol
Nice to see you back cant wait to see the progress of that project!
Oscar is a beast!!!!I hope he starts his own channel and start doing his own thing as a side hustle...
Awesome, can’t wait to see the boat come together!
Boat is awesome, engines looks great, content is amazing, great job guys!
Oscar is an absolute weapon every time I was him do this, I am a machinist by trade so I can appreciate most of what he does and he still blows me away
I love this channel, a great resource on how not to build things.
😂
The MOPAR Marine 440 was a very robust engine with heavier water jackets.
Gas engines DO have a history in marine applications.
You Do You Chris!
holy shit oscar is impressive, you guys gotta do a build just for him!
You rite
Ehhhhh, the Mustang? Did you miss that build? 😂
You must’ve missed like 8 episodes straight of him building his mustang
@@furhadnasserjah123 yeah i did, but i’m talking something insane like the huracan build
@@joealex65 i actually did yeah! let me go watch that one
I am surprisingly impressed on the engine build. Someone realized you need to cam the engine for marine duty, a “street” cam would not cut it. Good job.
09:04 today on B is for Build Chris uses a potatoes for a microphone.....
Those engines look sick! Can't wait to see them in the boat!!
In Oscar we trust!
MVP at it again, Welder Fabricator G.O.A.T. !!!!! Oscar the man, myth and legend!
"454 without power additives, and Texas Speed did the best they could with the high demand.."
[Cleetus has Entered the chat]
the old engines had nice turbos on it. this one have no turbos...
if you want tork and power. just boost the turbo a bit more.
Hahahaha next week on Cleetus’ channel: “Yee haw, I’m building a 454 Texas Speed powered yacht 🤣”
Ooooh man im excited for this. Perfect timing because I actually forgot about this project but was reminded of it last episode when you revisited the boat hahah. Looking forward to it!
"Were dealing with boats, so we wanted to get the most torque we could" *ditches the diesel engines and buys gasoline v8s..* didn't even have us in the first half chief.
I don't think he wanted to spend 60k on new diesels.
that's why he's got stroker engines
@@createachanneltopost 😂😂😂
@@rsdna9698 as they say buy once, cry once. A well built marine diesel will outlive 20 of those lsx v8, produce less heat in the engine room, and be significantly better on fuel and reliability costs.
@@createachanneltopost Explain to me how a stroked and bored out 454 cubic inch engine compares to a 903 cubic inch engine?
