hi, im new to the forum and live in the UK, ive read alot about the supercharger washers here, mine were replaced along along with a rebuild before i bought the boat. But im not sure how many hours they have now done.
Ive tried to turn the impeller on the SC by hand and it only moves 1/4 turn so im thinking the clutch is ok still?
Im thinking of having the unit serviced and the washers replaced or do i change the uint for a brand new X supercharger, if i did what would the benefits be?? if any performance wise and is it a direct replacement or do i need to do other mods ??

many thanks Barry
