ottwaybass Posted September 21, 2010 Report Share Posted September 21, 2010 It would definately lower your RPM's. Link to comment Share on other sites More sharing options...
softbaitmaker Posted September 21, 2010 Report Share Posted September 21, 2010 And probably push the boat a little faster with less effort too... Link to comment Share on other sites More sharing options...

softbaitmaker Posted September 22, 2010 Report Share Posted September 22, 2010 Thanks for info, didnt want to get a prop to big so it want be to hard on the engine I don't know about up that way but down here most of us go to Performance Propeller and Jim will let us borrow props to try on our boats to see if it is what we want before we have to buy it and find out it's not what we want. You might see if you can do that up there. They may want you to post a deposit or something like that but I bet they will let you borrow a few different props and even make some suggestions on different pitches of props to try......just my worth Link to comment Share on other sites More sharing options...
