just pulled the ride shoe... it has a crack in it, does anyone know where i can find a new one? Maybe aftermarket?

impeller is clean with no nicks or cracks

still cavitating, the old wear ring was worn only on the top and bottom if this helps at all. I'm running out of ideas here.

I have only run it out of water... weather has been pretty terrible here in Michigan lately

This is a great thread! I used this info, as well as the shop manual, and things went smoothly! I pressed out the wear ring with a screw driver, hammer and large bench vise to stabilize everything. This took me about 20 minutes, as I was cautious not to damage the pump housing. Good luck on this for everyone who is going to attempt. It is a very do-able event.

However... In my adventure I found more problems that I didn't know about. Who ever worked on my boat before hand didn't replace the impeller boot and my carbon ring was TOAST! so I'll be waiting a few days for parts so I can finish the job.

Also, I found a "RAVE" valve that had broken off in the cylinder. After inspection I have found everything to be still within tolerances. Are broken RAVE valves normal? What are the symptoms of valves going bad and what should I gain when I replace it?
