I am trying to find out what the clearance should be between wear ring/impeller housing and the impeller should be. It’s a 1991 Yamaha Waverunner 3 650. I have searched the web and can’t find an answer for that particular ski. Anyone happen to know? It won’t plain out and impeller looks good. There is what seems to be a pretty big gap from what I’ve read about other clearance specifications.
