RXP Supercharger failure. What to do next?
While riding the RXP last weekend, I heard a high pitch squeal so I slowed down and shut it off. I checked everything I could on the water and didn't see anything wrong. I tried to restart it, but it wouldn't turn over so I had to be towed back to the ramp. After a brief check at home I found no metal flakes in the oil, the coolant level was correct, the oil level was correct, and the plugs looked fine. Today I pulled the pump and then the supercharger. After pulling the supercharger I was able to turn the engine over by hand. The supercharger would not spin easily out of the ski and squealed when it did turn. The supercharger fins looked fine, but there was a fine silver dust in the hose from supercharger to the throttle body. I know I'm looking at a minimum of a supercharger rebuild, but based on the pictures below, what else should I look for? Would sending it to Jerry for a rebuild be the right way to go or would it be better to get a new supercharger? My current supercharger is an X-Charger with about 60 hrs on it. I'm not sure how much damage was caused, but I don't want to miss anything and have other problems down the road. Any help is appreciated. Thanks!

Split the SC. Sounds like you may of had a touchdown.

if you haven't lost and clutch parts or needle bearings consider this your lucky day!
Chances are the bearings failed allowing the impeller to grind into the housing (touch down). Typically the charger is toast and needs a replacement.
Some times the damage is minor and can be reused. ( I don't recommend reuse after touch down like this)
If any parts of the charger clutches or needle bearings are gone, your life now sucks as the engine needs to be pulled and gone through, along with needing a new charger.

Replace both bearing ... You must have too much horizontal play ...

yes very very very lucky.
New charger for sure.
try to clean up any aluminum dust that might be sitting in the manifolds.
you don't want to cheap out on a bit that spins 25,000 rpm a sneeze away from your pistons
and since you are so lucky..bonus...you can get a better charger with the cash you didn't spend fixing your engine

If you like the X charger , get an ET 127 made up ... They are bullet proof and more boost than a X wheel ..
