    They will end up about 12 newton meters after a few hours of run in. Right now you are at 17 newton meters.

    Metal washers will give you a higher slip moment than that of ceramic washers so you can't really go by stock specs.

    What type of wrench are you using? Did you squirt oil down the hollow part of the shaft before checking the slip? 17 NM is a tad bit higher than i have seen upon new assembly.

    If your SC nut is torqued to 22 ft lbs you are good to go.
    Usually if you torque higher than 22 you can get a higher than usual slip moment reading.

    If you pull your sc after 10 hours or so you will find your slip moment now at about 11-12 NM (105 inch lbs)

    I'm only getting 75 in lbs of slip on a 05 shaft. It's the same as the ceramics that came out of it? Have I done something wrong or do I need to put a washer in? Ceramic measured 1.49 and 1.50 Jerry's 1.53 and 1.545.
    POS Seadoo paper thin wrench.

    No you are doing nothing wrong. I have worked on 5 RXPs with stock reading of 75-80 inch pounds. All with low hours.
    This was with a exspensive mac tools dial torq wrench. I would say on average most stock ski's are around 80 or so inch pounds.

    Keep in mind that your ceramics are used and have worn. There are other critical places in the supercharger that can wear resulting in a low slip moment. All are easily remedied by installing a shim to increase the slip moment. Here is a very good thread showing areas of the clutch that are prone to wear:
    http://greenhulk.net/forums/showthread.php?t=15971

    I have one of the metal washers made .008 thicker than stock. .008 is the thickness of a shim

    To keep from bending your flimsy Sea Doo shaft holding tool use a propane torch to heat the nut up to break the loc tite. You will know when its hot enough as you will see the loc tite bubbling a little. The nut comes off like butter after that and doesn't harm your tool.

    Don't forget to go back with red loc tite when reassembling.
