425 HP Cummins QSB engine.


On the other end of the performance spectrum, WOT is 3000 RPM where the
boat makes 16.5 kt at 22.4 gph.


Who the hell runs a diesel at WOT? I'll bet at a more reasonable engine
speed, say about 2400 rpm, that 22.4 gph drops to about 10 or 11 gph.



2400 = 80% of WOT = 64% of max hp = 272 = approx 15 gph.

For some reason or another, the reading we got on the engine diagnostic
screen was 12.2 gph at 2400.
