This past weekend I replaced my wear ring because the old one was badly damaged (as seen below!)and I was getting pretty bad cavitation. I had no problem getting the old one off and putting the new one on. I did not remove the impeller.
I took my jet ski (1998 gti) out for a test run this weekend hoping that all my cavitation problems were solved. It wouldn't go anywhere! Come to find out the pto shaft actually went beside the impeller instead of in it! This caused a minor groove to be worn in the impeller. Do I need to replace my impeller or will it be ok?
Now when I run it, it is still cavitating terribly! It has very very little propulsion and is taking on alot of water. Searched and found that the carbon seal is the culprit. I believe the carbon seal got damaged by the pto shaft not being inserted in the impeller and therefore causing flop in the shaft and damaging the carbon seal. Here is where my questions start. How hard is it to replace? I can now take the pump off in less than 15 minutes lol due to having to take it off 3 times in the past 2 days. Does the shaft slide out of the stainless collar? Should I just get the driveline repair kit from sbt? http://www.shopsbt.com/seadoo-jet-ski-driveline-rebuild-kit/70-105B.html
Also I would appreciate any information on how the carbon seal works. It seams that it wouldn't seal much?!
Is this shaft suppose to "bubble out" on the end?
