I have a 20 x 22.3 inch 5-bladed prop in my 2004 Pilot 30. Previous owner had it "tuned" or balanced at a prop shop before I purchased it this year. During the Sea Trial part of the survey, the boat reached 3825 rpms and around 25 mph average of 2 directions. Power is Yanmar 370 hp 6LPA STP2. No vibrations were noticed.

My mistake, thanks for noticing that. The model number (6LPA-STP2) is what I have written correctly above, but the horsepower is 315 and not 370. My transmission is ZF Hurth, ZF 63A-25. Ratio is 2.5
