Say I run a 28 pitch prop that slips 15% at 7000 RPM and I go 84 MPH. Then I try a 25 pitch prop that slips 5% and goes 84 MPH at 7000 RPM but is a dog out of the hole because it doesnt spool up fast enough I havent really gained anything by slipping less.

Re: prop advice please, 50hp Johnson 2 stroke on a 17' aluminum bass boat I figure your at about 1600 lbs. I wonder if your ventilation may be prop related more than motor height.
