Just tried out a new Solas in 9.25x8 yesterday; standard prop is 9.25x9. I went lower to gain better holeshot and to help when I raised motor higher. Boat runs great....except, my revs are too high. On second hole/trim position, I averaged 22 mph at 5900 rpms and on third hole/trim position, I averaged 22.8 at 6150 rpms. Both of these rpms are outside of 5300-5800 specs. I didn't cavitate or porpoise so I'm thinking homemade JP can go 1.5" higher. Will that make rpms even higher? Thoughts?
