I remember seeing a while back a boat being rigged with Marine Duramax engines. It was yellow is about the only thing I remember.

What ever happened to this boat? did this work?? I actually thought gm was behind it.

The reason I ask is I just got a new duramax truck (my first diesel). And the torque is crazy. And you see guys getting 1200+HP out of these engines I would think it would be a good fit especially when you figure you can cool the exhaust with water.

I think Banks marinises duramaxes or they at least used to for work boats..

Yeah I searched the forum a little and found some stuff. I was more interested if someone had done a high HP version.

As said banks builds duramax motors to order, but cummins/merc offers a performance based 6.7l straight from merc.

Someone was building this (the old Tommy Bahama MTI) with a Duramax motor a while back but I never heard whatever came of it.

I built a 900hp duramax for my 2500, let's just say for a boat buy a Teague big blower motor, it will be cheaper! Pistons $3000, rods $3000, heads $5000, turbos $7500...... Etc etc adds up even faster than boat parts!

The guys at FASS fuel pumps told me that old Tommy Bahama MTI is running their pumps on the Duramaxes. That was the only marine diesel application they had done prior to mine. They didn't have any details though.

wow

Impressive

Sweet!

Anyone know what the boat was that they tested these motors in?

And can someone explain how a twin turbo'd AND supercharged motor only puts out 700hp?? Explain how 700 HP in diesel format is different from 700hp in gas format please.
