2005 Sea Doo Superchrger


120 hours on ski (2005 RXT) without a rebuild of supercharger. Lost hp this weekend - speed topped out at 40mph). Started researching and discovered the SC only last about 100 hours. Any chance the SC stops working without putting a bunch of metal in the engine?


Yes, it’s possible. Pull it and take a picture of the back of the assembly and I’ll let you know what’s up


Hi, Joe.

I pulled the supercharger. As an FYI, I ran into an issue with the top mount bolt. I stripped it. I used a dremel multi-max mm30, with a carbide bit, to cut the bolt head. No problem. Took about 2 minutes.

Please see attached pics and let me know your thoughts.




So hate the be the barer of bad news, but looks like ceramic washers and one is missing.

Here is a link to SeaDooForum with some more information on what comes next:


Thanks, Joe. Appreciate the follow up.
