2016 Sea Doo RXT 300 supercharger Failure

[Billpro785]

Hello, just signed up on the forum. Have 2016 Sea Doo RXT300 RS, that had a supercharger failure at 148 hours. Shaft is broken, and impeller damaged. Wondering what could be the cause ? Oil is changed every 45 hours, and at 100 hours slip was checked. was at 13nm.

Have not seen any other recent SCs failures reported on the forum. BTW the “maintenance free” did not start until 2017, yours was under the every 100 hours or 2 years interval assuming you did not have it rebuilt previously.

have a Sea Doo factory manual and stating in 2016 the only maintenance is to check the slip. Check the Sea Doo parts website, it lists no spare parts for the 2016 300 supercharger.

“Sea-Doo began marketing certain superchargers as "maintenance-free" in
2016 for their 300-horsepower models, and this change extended to all supercharged models starting in 2017.”

My mistake.

Keep the sight posted on how you proceed with the aftermarket rebuild or OEM replacement. Maybe someone with a similar failure will post.

Will do, going to do the rebuild myself. Used to be a A@P mechanic, figured If I can rebuild jet engines, should be able to rebuild a supercharger.

Replacement impeller arrived today. As you can see in the photos the ribs do not extend as far. This would be what I assume the gen 2.
Going with the WSM rebuild kit. I have used their kit for the 260 supercharger before, and had great results.
