    They are ABEC 1

    For those that don't know about ABEC ratings, ABEC 1 is a standard precision bearing.
    The higher the # the higher the precision. All this means absolutely nothing in the ceramic bearing world. People have a lot of wrong information on what is better. An ABEC 7 high precision bearing in the same size i'm having made for our superchargers would be over $200.00 in ceramic per bearing ($400 per set) and be no better. Higher ABEC rated bearings are used in CNC machines where run out tolerances have to be held tighter because it will affect the part being made on the other end. Also,higher ABEC bearings only work when mated parts are of equal precision too.

    My bearing manufacturer has tested so many different types over the years and and told me there is no gain to making my supercharger bearings a higher ABEC except costing the consumer more. Hope this helps!

    The superchargers have stock ceramic clutches.......not bearings.

    They have ceramic clutch washers!!! and no, the 04's are not better than the new ones. The 06 and up are the best.

    All sea doo supercharged watercraft have metal ball bearings in the sc, including 07.

    Fortunately, we have available to us improved metal clutch washers and improved ceramic bearings.

    Hope this helps

    At what point do you recommend to change out those parts?

    I do not use the ski heavily, as you see, and dont have higher than Stage I right now.... I dont plan on this going in the ocean either....
    The max I plan to invest is Stage II, well close to stage 3 minus the ECU and valve spring upgrades.

    thanks...

    I would suggest getting rid of the ceramic clutches as soon as possible. If you send the charger to Greenhulk he can install the metal clutches, while he has it spend the extra for the new bearings. Probably doesn't need bearings yet, but you will have a dependable supercharger.
