    No it isn't the wheel is always balanced by itself . The whole supercharger kit has no any dinamic balance . The bearing has been broken for other reasons .

    yes, it’s the 2019 and older 230’s use the exact same rebuild kit as 2008 and newer 255 and 260 skis. This is the rebuild kit you need

    If you're only adjusting torque slip, no you don't need to balance it.

    just wanted to add if not mentioned. I have installed many 137+ wheels on these chargers...ET or Riva. Never had one fail...we rev them to 9200 with no issues....NEVER BALANCED ONE YET

    How much boost do those wheels make at that RPM?

    I recently calculated the supercharger wheel RPM ratio to crankshaft RPM. *

    Seadoo (recent model years) supercharger gear has 16 teeth
    Seadoo flywheel drive gear has 87 teeth
    87/16 = 5.438 overdrive drive ratio
    So 9200 engine RPM becomes 50,030 RPM at the supercharger wheel

    For contrast, the Yamaha SVHO supercharger turns at 9.897 times * the engine crankshaft RPM.
    Which means the SVHO wheel is turning 91,050 RPM when the SVHO engine reaches 9200.


    * If my math is incorrect, let me know.
