I am running a 13.25 17P SS powertech prop. I run about 31-32 MPH. When I trim up about half way between fill down and 3/4 of the way up on my trim gauge the boat wants to porpoise. would anyone recommend a 4 blade aluminum prop. I want to maybe find a 15P. My old 15P 3 blade aluminum prop I was turning 5850 rpm. I want to try and find a 4 blade prop that is a 15P or smaller. Max RPM is 6000 for my 01 2 stroke
Anyone have an suggestions
