    what was the reason that BRP used ceramic washers?

    Does anyone know why BRP used the ceramic washers in the supercharger in the first place? Do they bit better then steel?, did they think they would wear better?

    Ceramic disappates heat better
    Heat/friction has little affect on the characteristics of ceramic.

    In many cases and applications ceramics are better than metals. In theory the ceramic clutch washers are better than the metal. Real world they are not as we have seen.

    In the service manual, Sea-Doo states in the supercharger section "Note: Ceramic washers are not affected by wear". They wouldn't have been able to say that with metal (of course, there are many other parts on the SC shaft that do wear). They made them a little thicker starting in '06 to try and remedy the breakage problem, but it seemed to only make it worse.

    It was a good idea/it was a bad idea.

    The first 4-tec SC had metal washers I'm pretty sure. BRP used synthetic in these skis in the SC started to slip badly. Then they switched over.

    I could have this slightly wrong, so correct me if I'm wrong.

    03 had metal on metal contact surfaces that acted as the clutch... but there were no clutch washers... no ceramic or metal, there just were not clutch disks at all... thicker lock washer took up the difference and the drive gear would slip against a metal locked surface...
