I have a 22ft Aquasport with a 1988 200 hp Evinrude on it. It currently has the original prop that came on the motor (aluminum) is there a benifit to going to a 4 blade prop? If so what is that benefit? I use the boat for offshore fishing.
Please read the stickies at the top of the prop forum and get us all the info you can.
your present prop size should be under the prop nut. we need the wot rpm and gps speed.
