I have a 91 Johnson 50/35 on a 14’ river runner. It takes longer to get on a plane than I would like. At WOT it runs 5000 rpm whether accelerating or on a full plane. The throttle stop is set so the intake is wide open. I think the holeshot would be faster if I could get rpm’s up to 5300-5500 since there would be more thrust. Jets have fixed impellers so I can’t change the pitch.
Thoughts on how I can increase rpm’s?
