Re: how often do you change your impeller?
I've changed mine 3 times in 30yrs, I didn't know your supposed to change them every year until I joined this forum, I guess I got lucky, always in fresh water and seldom in any mud or sand, I think that makes a big difference, the old impellers have always looked good besides a little curvature of the wipers. I just put a new one in last week so I'm good for a few years.
