2005 Seadoo challenger couples seized

I am at the end of my rope at this point. Coupler that sits over the lock ring won’t budge. Trying to swap out the shaft and replace the carbon. Any ideas to get that off would be helpful otherwise I am cutting it out.

I had a similar issue. I used a pry bar braces against a wood block on the engine on the inside to push back the coupler, while my kiddo used a rubber mallet on the outside. About 6-7 hits later it finally moved and revealed the c clip. Was a pain in the arse.

I just did mine a few weeks ago. The supercharger is in the way. If you remove it you can get more leverage. BTW, I used a pickle fork for removing ball joints/tie rods on a truck as the pry bar. 3ftdeep has a good video, its done on a ski but thats where I got the pickle fork idea from.

I've had this tool for about 5 years. It's my go to when pushing the collar back on all 4tecs and no need to remove the supercharger...

The key is getting it to spin first. Have had to grab with vice grips, put a wooden stick in the impeller, and break it loose on a few. Sometimes saltwater ones are really bad and have to be cut off.
