I have the same boat with about the same hP but I got about 75 lb more tork. I am running a 26p prop @ 5400rpm. My boat is loaded with gear and with all the extras it is heavier than when I got it. I would think you should see around 75mph.

what rpm was max HP & tork????

MS 28 SCARAB I would try a 26 Bravo or a 24-25 hydromotive. We are going though the same thing now trying to get a 30p Bravo to run at 6000 rpm. with are new Richie Zul motor.
