Going to ponchatrain this weekend for poker run. Boat will leave shop in Houston friday so no time to test. Static run with maximus 36 only got 3300 rpm. The first and only test water run with 28 4 blades got 68 MPH at 3500 before a hose came loose and had to stop..I also have some 30 inch 4 blades. Need to use something that has a chance to work. any advice helps. If you know wha another 31AQ is using would be helpful to me. have 750 HP blower motors + Bravo uppers, Imco extention boxes and lowers- HELP!!

I had a 31 AO with 750 blower motors and a 1:50 gear and ran 32's. At 3000 was about 72 and at 5800 was 106 if those #'s are any help.
