What pitch prop gave you these numbers?

Yes, I tough I would get better, 3 runs on flat, trimmed in the sweet spot and 5250 to 5300 at 38-39 mph, and yes motor height is good, see the cab plate while running just skimming the water line , bit under bit over but the spray is gone, almost feel like I could go one more hole up, but in the slop I will probably cavitate, so yes I think a 15x17 would put me at about 6000, my Honda prop fits on that engine too, it’s 14-1/2” x 15 x 4 blade, it was the best on my 225, 40 mph at 5800

Got a 16x17 waiting for me at Sherwood,prop guy says it will put me 5600 , said close enough, will also order one one these, so I can play with height without pulling bolts out all the time f….

Nice jack plate - Once you start playing with mounting height, you start to realize how much of an impact it makes - and how few outboards are mounted correctly out of the box.

When I got my boat it was on the second hole, I remounted it twice and am now at the top hole and anti-cav plate is now just skimming the water. Getting your outboard mounted right makes it feel like your boat started going to the gym and went on a diet.
