    what is the sc belt? this is my first jetski and just starting out

    sc belt is the supercharger belt that is connected to the engine pulley.
    Maybe the belt is worn out, proper tension is gone and needs to be tightened up, etc.
    Get a service manual.

    i changed the whole unit.. belt also. if the belt isn't slipping take the rear fat hose of the sc and dc the belt.. if it revs up high Id say u need a new supercharger.. these things are a ball ache. supercharger will be around a thousand quid mate.. how much did u pay for ur ski btw? also... isn't fuel like 1.70 a liter for high octane there? lol ouch this things going to nip ur wallet. i used to live in inverness. cold for skis there 4 sure.
