I'm curious as to how much weight change will do to the balance of your boat. I wonder if it will plow or sit proudly out of the water. Weight shift is a big problem with remotoring a boat.

I'm not sure what you're thinking, but what happens if the water in the bottom of the boat freezes?

Fun content to watch but the Rube Goldberg approach raises questions of long term reliability. They are going to learn that BOAT stands for, "Break Out Another Thousand".

EXCUSE MY IGNORANCE....Can you put the intake facing foward ??? Or does it go facing backwards only ??? 🤔🤔🤔🤔🤔🤔🤔

This is the train wreck I can't stop watching. I've had a 100 ton USCG license for 45 years and owned several large diesel boats.... I just can't get over the amount of time, money and talent that is being wasted on this project. Cheaper would have been to just take a used Cat 966 frontend loader and put the LS in it.... see how that works! Time and effort saved!

Now that you've converted from diesel to gas, everything in that engine room needs to be ignition protected. Examples, alternator, starter, fuel pump, all AC and DC electrical devices in that engine room. You don't want gas fumes ignited by any of those non-ignition protected devices! Check the USCG regs and ABYC recommendations. Good luck.

Put a filter on the air line to your plasma torch and you'll get a much cleaner cut. Like your fancy spray paint machine, any debris, especially water and / or oil, in the air line will make for less than desirable results.

In the yacht world we would normally install an aqualift & separator into the exhaust system which keeps the height/noise levels to safe limits!

I’m guessing the generator is diesel since the engines were, and he will have to build a separate fuel tank for the generator.

@BisforBuild YOU GUYS DIDNT BACKPURGE WELD ANY OF YOUR STAINLESS THAT LOOKS LIKE 304. STAINLESS WELDS NEED BACK PURGE WELDING. YOUR WELDS WITH NO BACK PURGE WELDING WILL LOOK LIKE CRYSTALLINE SUGAR, AND WILL NOT BE RUST RESISTANT, IT WILL BE EXTREMELY POROUS AND A SPOT FOR CORROSION TO EAT AWAY AT THE METAL MORE QUICKLY THAN JUST THE 304. ON A SECOND NOTE, 304 IS USELESS IN THE MARINE ENVIRONMENT, YOU NEED MINIMUM 316L. LASTLY, I BELIEVE THAT THE 1/16" WALL TUBING YOU HAVE CHOSEN IS FAR TOO THIN FOR THE ABUSE THAT A BOAT SMACKING WAVES REPEATEDLY WILL SEE OVER ITS LIFE SPAN. IF A WATER JACKETED EXHAUST PIPE WERE TO CRACK OPEN YOUD BE PUMPING THE JACKETED WATER INTO YOUR BOATS HULL AT A VERY HIGH RATE. PLEASE SIMPLY LOOK AT THE PART YOU'RE REPLACING AND THINK TO YOURSELF, WAS THERE A REASON THEY USED SUCH A THICK MATERIAL IN THE FIRST PLACE. SECOND GET A SECOND REGULATOR, AND SOME TIN FOIL AND LEARN TO BACK PURGE YOUR STAINLESS FOR WELDING, ITS REALLY SIMPLE STEPS YOU FOLLOW, AND COST YOU A FEW DOLLARS, LITERALLY ALL YOU NEED IS AN EXTRA REGULATOR AND ARGON TANK.... NO EXCUSE NOT TO BACK PURGE STAINLESS. PERIOD. FOOD FOR THOUGHT. IF YOU SINK THIS BOAT BECAUSE OF A FRAGILE PART YOU BUILT INCOMPETENTLY, THIS VIDEO WILL BE ALL THE EVIDENCE YOUR INSURANCE COMPANY NEEDS TO DENY YOUR CLAIM.

Maybe someone suggested this, but it was too much to scroll through the comments, but what if you angle milled the manifold so it sits away from the valve covers, then mill the elbow surface to have it sitting vertically plumb. Cool video BTW, Dundee, Or here!

I keep wondering why you didn't get the boat towed back to it's berth in your local marina when its engine popped? I'm assuming you still have a space allocated there (And you're still paying for it), so wouldn't it have been cheaper in the long run, and WAY more convenient to have kept it in the water until you were 100% ready to do the engine swaps, and THEN get it lifted? Doesn't your local marina have a crane and a work yard ? Or was this one of those occasions where things needed to happen fast and you had to take the choices that were immediately available at that time? I'm still a bit dubious about going for a petrol (Gas) swap, but it's your project, so your choice. You seem to have been doing your homework, so hopefully it will all turn out well for you.

With your spacing issues, have you investigated making exhaust port spacers to move the headers away from the engine thus giving you more clearance around the intake and rocker covers? Though it may necessitate moving the alternator again (maybe rotate them 180 degrees so the connectors are on the top?)...

I'm thinking if it's expensive to keep the boat out the water and there why don't you get it transported to your shop also its right outside so no 4 hour round trip for 10 min measurement ect I'm unsure where your are but in UK would be cheaper to move it rather then store it either way looking forward to see how this all comes together and I absolutely love the boat it's self looks so nice

I know nothing about boats. It sounded like he said the exhaust gets mixed with water then dumped out the back? Not filtered, nothing? So just burnt fuel mixed with water being dumped directly into the water? Not saying that's his fault, seems like that'd be common practice if that's how he's doing it. Not cool tho...

Everybody thats knocking your decision to go gasoline based vs diesel based dont realize that a shit load of boats had and still have massive gasoline engines and do just fine. I have twin 454 Crusader CID gasoline engines in my 32’ Tiara which push out ~700 crank HP and are super powerful (low end). Gasoline engines can absolutely do the job. Diesel might be a lil more suited for marine applications but regardless gasoline engines do just fine in boats so this is exciting actually for me to see. Boat engines are absolutely massive so its going to be interesting to see how these engines hold out. My biggest concern is not blowing a head gasket while running under prolonged high RPMS (they seem to want to go fast but that bot wasnt really build for speed).

O2 sensors don't function below 600 degrees Fahrenheit. Water cooled exhaust manifolds don't retain enough heat, and when I left the marine mechanics trade the ecm's all ran GM controllers in open loop, primarily on S/D, and alpha/N tables.

I can hardly wait to see what prop(s) he tries. They’ll run about $1,200 each and have to be spot on matched to boat hull, weight and engine/final drive output to prop diameter, pitch, blade count and blade style. Boat builders will try about 6 before they settle on the right one. It’s not just top speed but just getting there. If that motor is all top end, it may lug or hurt it’s self trying to get there. It’s not like you have different gears to shift or a clutch to slip. Too small of prop and he can’t use full throttle because it’ll over rev. Online boat propeller calculators only get you in the “ball park” with a known marine engine torque curve. Not a “built” performance motor. I hope he gets lucky. On a prop selection only once did I get lucky, and I had a reference prop. Oh, than there’s the haul out fees of 10-15 dollars a foot each time. B.O.A.T. = Break Out Another Thousand. Definition of a boat? A hole in the water in which you pour money into. Good name for a boat? Money Vortex.
