Thanks Phil,

Still not sure? I would think if my prop is slipping (spinning too fast or not gripping the water effectively) that my WOT would be higher than required with my current prop. My WOT now is only about 4000-4200 rpm's. I'm concerned this is too low.



Since you already have a prop that is not particularly aggressive (13 3/4" diameter x 17" pitch), it seems to me the issue could be fuel delivery more so than prop size/pitch.

Is your engine able to rev any higher when it is in neutral?
