How will I know when it's time to change the wear rings on my PWC?
It's never a bad idea to keep an eye on your Sea-Doo's performance. You'll also want to check the jet pump periodically. You're looking for any sign of damage and/or accumulated dirt. Take a close look at the wear ring, which is wrapped around your PWC's impeller. The surface of the wear ring should be smooth, with minimal scratches. If you notice a significant gap between the impeller and the wear ring, it's time to replace your wear ring.
