I am in the process of re-powering my 17ft. Renegade Skate. (has a tunnel) I blew up my super-reliable ;D 50 Force motor about a month ago. A friend from church had an old bass boat lying around with a 1994 Johnson 90. It has an old aluminum prop on it. I'm thinking I want to get a 4 blade prop that will bite better when the motor is jacked up. I don't know where to start with pitch, etc. Any suggestions? I was thinking of a Renegade 4 blade prop. I think I could get one for about 100- if I look around some, but I dunno if that's a good idea or not. Thanks, any help is appreciated.
