One of my friends had the same boat it was around 75ghr at wot

Here diesel is less than super, and he said his motors were 30K each same as Yanmars.

Might have similar mpg, but the performance would not even be close.

I get 2.0mpg running 55-57mph @ 3500rpm with my 598ci N/A, pushing about 750hp. I have no clue what it burns at WOT 6000rpms though. and I would probably cry if I did know.

Way better MPG for sure.

I dont think performance would be anywhere close.

I just saw small block but now i see the LS7, boat would probably still run 80-90 though with 6LPA's, even better with the new V8's 370 hp each.
