Have you tried swapping the prop rotation?
That will affect the stern lift.
I think 3 blades will be faster on top if that is your ultimate goal.
I've been told to prop for peek HP +200 -0.

I just spoke w hydromotive and they think 4-blade is the way to go, either 21 or 22p. I'm going to flinch when they quote me, I may go for some used bravo 4 blades

the boat has so much traction I'm not worried about the mid range, I mean it planes at 2100.... I am aiming for 80mph, if you think a 3 blade cleaver is right... hydromotive may just be selling what they have on the shelf, he was pushing rough water, riding on the "tops" performance, no worry with this boat either. I have done some nuts rides, catching the tops in sick conditions. ive got my gps working so will have baseline numbers tomorrow

Bravo 4 blades will not give you the stern lift of the hydros. they are 2 very different prop designs.

Search for a set of used hydros. they're on ebay all the time.

I like the layout of the superboat too it seems conducive to intimate positions with its low profile. You guys are gonna hate this I have water in one crankcase, Ill be posting over somewhere this ones a stumper it holds 15 lbs in the crankcase cant figure where its coming in not the oil cooler
