I think the drives have something to do with it but also only getting slightly over 5000 rpm and one motor is only getting to around 4600 rpm.

I run Bravo drives 1,5 with Bravo 4 Blade 30's I can get 4650 to 4750 RMP I don't think I would get any more speed propping to 28's and the RPM would be tougher on the motors. It jumps up on plane with no problems and this is heavy with fuel. I can probably get 4800 light and cold weather.

Can any of you 28 Saber owner's help a brotha out and let me know the max height the boat is on a trailer. Also, please state whether or not your trailer has torsion axles or not.
