Good afternoon all,<br /><br />So the Lower the pitch number on the prop, the lower the top speed right? If i have a 13-3/4x 15 now, but i want more hole shot for pulling, i just go down to an 11 or maybe a 13, but keep the same diamater right? Its kind of like downshifting to a lower gear in your car right?<br />For a guy that doesn't care about top speed all that much, and wants to be able to pull skiers out quicker, it would probably be worth the loss in top end to have the punch on the bottom right?<br /><br />Thank you

Re: Very Basic Prop Question

Sounds logical, Maz, but it isn't that simple.<br /><br />Either overpropping your engine (can't reach top of operating rpm range) or underpropping it (over-revs at WOT) can lead to destruction.<br /><br />It is like selecting another gear in your car, but you have to stay there all the time. That can break your car, too.<br /><br />Gonna move this to Outboards
