Marinizing GM DuraMax Diesel

Re: Marinizing GM DuraMax Diesel
Great thread guys!
I'm extremely interested in the duramax, and reckon it would be a perfect marine motor.
I currently run a pair of 6.5's in a sportsboat in the UK, which I marinized myself, they make 325hp a piece, but I think the Duramax could easily make mid 400's when sorted.
Raylar, I'll keep a look out for your posts, but would rally apreciate it if you could drop me a line (PM) or post something about this project on the forum of our British site at www.boatmad.com when things move along.
I'm sure this would be interesting to many people here due to our high fuel costs.
here's a link to some pics of my motors/boat

I'm interested in the "Duramax" engine... for use in our Hovercraft.
We don't need a marinized version for our application, just an ECU setup to run the engine outside of the truck!
Is this possible at the moment? Is there an Industrial version?
P.S. we're currently running a supposedly modified 6.5 @ 300hp in our smallest craft at the moment. It doesn't have any GUTS!!!
Thanks,

Torque converters multiply torque. It might smooth out any torsional vibrations, but it'd be increasing the overall torque number that the motor sees.

why do you think torque converters multiply torque ? all a tC does is essentially convert rotary motion thru a fluid coupling. in practice they absorb and consume torque rather than multiply it unless there is a specific gear set AFTER the conversion... and they make all the heat in the universe while doing it.

Unless input and output speeds are the same, the torque converter is muliplying torque. Oftentimes doubling the torque or more.

Depends on the gear ratios in the trans. Usually the automatic will have a higher (lower numerically) first gear than the manual. They manuals usually have higher (lower numerically) rear end ratios. Plus you have to figure that when you're engaging the clutch, the inertia of the engine rotating at a higher speed than the driveline puts an extra dose of torque into the driveline (which is why you can spin the tires in a turd if you drop the clutch at a high enough RPM).
