    Pitch perfect

    Update, I purchased a spitfire 15 4 blade. First run with the new prop I can hit 21 mph with 25 gallons of fuel and 3 adults. 5600 rpms. My rpm range is 5000 to 6000. I think I found the right prop. No cavitation and I can hold a tight turn at 20 mph.

    Any adjustment to the trim causes blow out. I have to keep the trim all the way down. The cavitation is a known problem with the boat manufacturer. The manufacturers suggested fix is a 4 blade prop and a hydrofoil on the motor. I'm just trying to decide if I want to try a 13.4 x 15 spitefire or...
