I have a V hull 16" G3 with a 50 HP Yamaha 2 stroke. According to my instruments at wide open throttle I'm going 30 mph and revving at 4400 rpm. That's with the trim adjusted for maximum plane. I don't know the pitch of my prop, but 4400 rpm makes me think I might need a slightly different prop pitch to get the most out of this boat/motor combo. Am I right about that?
