Diesel powered sport boats?

But impressive performance nonetheless I agree.
The durability for a diesel is considered 15000hrs/1000000miles between overhauls.
Not 60hrs like a blower bigblock or 600hrs for a normal bread and butter marine V8.

So 440-525+ no harm done if EGTīs are kept reasonable.

Ive heard of this being done, actually came from Super T. One of the diesel guru's...500-525hp and 350 pounds less equates to performance on a diesel boat. I still prefer the electronic 480hp and am looking forward to hear what the increase in power will be. Im not into smoke, so a turned down or somewhere inbetween, possibly 525-550 hp will be enough for me, and should be enough to get close to my desired speed. Jeff

mikeyFIN... what part of the country are you in? I can't find a diesel dyno around here and hope you are in houston. it seems all of them ust some dyno that they pull the trucks onto and strap them down... Well goog luck with your project, this diesels in sport boats/cruisers seems like an alomst open frontier, if anyone can get their feet in the door.

Topspin..edited my Profile...sorry but canīt give you any immidate solution.
A diesel Dyno in Houston Area....hmmmm?
Well Anyone with an Engine dyno capable of taking what you got.
Smokey Yunick used to do just that in his Best Damn Garage in Town.
If not anyone In USA can provide heck then I might have to relocate :-)
Hereīs someone I think might help you?

If thereīs a lot of smoke it means itīs running rich... common with turbocharged diesels before they get into the boost zone.
So what to do..add a supercharger that gives enough air down low or tune tune tune with todays electronics the PPE vid was a proof of todays engine.
Volvo has done it in the smaller diesels for marine use.
Remember Smoke is a sign of unburnt fuel.

Over here people are onto tuning old Mercedes 300TDīs (now thats only a 3 liter engine) that in street trim do low 11 second times at the quarter. But to get into those numbers there has been many blowups and the engine lifes seldom go over 50th miles if you keep on punishing them at the strip and in a boat the stress is like a constant uphill run on the road.

As much as I like the C ummins inline 6(my truck is powered by one), I think the Duramax V8 would be the better choice as almost all engine compartments are configured for V8s. Jassby's 43 Nortech V had to be built with two Yanmars instead of three because of engine bay length limitations. If the Duramax had been available he probly would have put three in that boat.
Gale Banks is a well-known diesel tuner here in the States and he built a road race Chevy S10 with the Duramax/Allison and it is beating up on every truck in its class with just 650hp.
I like the SDS shiftable crash box with the ASD8/10 drive with this motor in a marine application. Now please will somebody do that??

The only way to get 3 Yanmar's in is go to the 50 Nortech which is actually 52'. It is impossible to get 3 in my 4300 which is actually 44'8" or a matter of fact any 40-47' boat with out modifying the cockpit. Even the 50 Hustler which is 49'6" had to put 2/3rds of the motor under the rear seat. They have a very deep boat and it worked. When you add the 3rd motor you add weight, and these diesels are not light, so you have to make sure the boat is capable of handling it. My boat sits great in the water, and has a level attitude. As to the Duramax diesel, I'll wait till they are out and tested. I'm glad someone is working on them. For right now, I'm liking the tried and true Yannie straight 6, for longevity. Jeff
