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!!

what gear ratio? I would try 32' 4 Blade bravo's for starters, should be close if your a 1:36 are you running 2'" shorty lowers?

it is 1:36 ratio and I am not sure if they are shorties, the Imco lowers - I am gonna try the 32 four blades- will advise results and thanks-

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.

I ran about 40 minuits before starbord motor shut down. Lake was very rough and went to intercostal for run to slidell. ran the 4 blade 30 inch props and was gps 82 mph at about 4400 rpm. never got to wot as was trying out all new gear after 3 yeat restoration. beleve there is fuel blockage issue and boat is going back to houston for repairs. will keep trying and thanks for advice- will post pictures soon-
