I have a Suzuki 20 motor with a 10" pitch prop. My dad an ole boater from way back went for a ride with me and we had trouble planing. We are at 5200 altitude and lose HP here. He immediately said you need a prop. Went into his days what he did to get his to plane. Well for my birthday he bought me a 8" prop, which I'm thinking is just right. Is the RPM change the same on all boats regardless of HP? My motor max rated is 5300-6300 RPM. We just barely hit 5300 when we were out. Alone I plane ok and can just get 6000 at times.
