Propeller question

[Rick Sherman]

I have a 2026 Bennington S22 SSB model. It has a 2026 Yamaha F series 150. The current prop is a SS Yamaha Reliance ( 14.50 dis X 15P. With 2 adults the WOT is right at 6000. With 4 adults it does ok. Needs 4000 rpm to cruse oand stay on plain. With 6 adults it really struggles in the mid range to stay up on plain especially in rougher water. I have read in several places that the 4 blade Yamaha Altima works much better in the conditions I am struggling. I have also read that I should reduce the pitch from 15” down to 13”. My biggest question is will the 13 pitch 4 blade be enough pitch reduction to keep us under the 6000 max?
