Moving the thread from ask Mac to a more generic forum.
With my old KAMD 42 inboards I ran
22 knots/ 3100 RPM, half full - 18 GPH
20 knots/3100 RPM, full w/ canyon ice and crew load
24 knots/3300 RPM half full - 20 GPH
22 knots/3300 RPM canyon load
25 knots 3400 RPM half full - 20 GPH
23 knots 3400 RPM canyon load
30 knots 3800 WOT/ half full
26-27 knots 36-2700 RPM WOT/canyon load
Needless to say I was overloading the engines at full canyon load.
I'm repowering w/ D4-260's this winter and hoping for canyon cruise of 25-26 knots, lightly loaded cruise of 29 knots.
