I am currently running a 26 bravo..stock prop..I was wondering if I switch to a 24 maxium 5 blade will that give me any performance gains? OR will it actually slow me down on the top end becuse of more blade serface??

It depends on the boat. With a deep X dim, it will most likely cost you some top end speed.

i have a 24 outlaw..mild built 502..x dem been raised 3 inches..

Baja's like bow lift and the Bravo 1 will have more bow lift than a Maximus.
