Can Oil cap cause super charger problem?
06 RXP, dealer instaled metal washers at 40 Hrs. Now at 50 hrs. Cant get above 6400 rpm.
Found oil filler cap off when I got in. Doesn't look like any oil came out or water got in.
Can this cause it to act like the supercharger is bad or is the supercharger bad?

OR, you had a washer break off the shaft
In either case just pull the hose off your supercharger and try to spin the impeller with your finger. If it spins you have work to do!

I was right! Ed, i just put new washers on your supercharger (the correct washers). You might have an 04-05 ski but this is an 06-07 clutch kit.
The 06-07 washers are thicker than 04-05.
Your dealer had installed 04-05 washers so the clutch slipped from the get go. The worst part is that a piece of washer broke off from slipping and overheating. Your dealer should be able to fish the broken piece from the front oil pump screen.
Supercharger is on it's way back to you today.

Any good quality SS screw type clamp will work perfectly.

ETA: If you have to take it somewhere take it to a specialty shop.

I still have a broken piece of the washer to find. I did searches on this site but haevn't found any tips or procedures to get at the screen in the oil pump. Any help would be appreaciated.

Ed, have a look at the exploded diagram in my OE parts store. Look under oil scavenger pump. that will give you an idea of what you are looking at.
The front screen is easy to get to on your ski. Just remove it and hope that you find the piece of washer there.
Now, i don't want to scare you but i have seen this happen. The broken piece of washer drops down between the timing chain and gear and damages the timing chain. If it were my ski i would pull the valve cover off and then rotate the engine very slowly and inspect every tooth on the chain. If that chain breaks while riding the ski you will have lots of bent valves.

Ski back Together
Thanks Jerry; Got the supercharger back today. Installation went good. Took off the valve cover like you suggested; everything looked OK. Pulled the oil pump screen and found the rest (hopefully) of the washer(pic attached). "The front screen is easy to get to on your ski" I don't think anything on my ski is "easy" I think "easy" means probably doable as compared to "hard" which would mean "not a chance in hell". All in all it went well except for the two quarts of oil I put in the bilge because I didn't have the oil screen in right and the cover leaked. Not many good riding days left. Saturday should be nice so I hope it runs well.
Thanks for everyone’s help. Ed.
