This looks like a pretty inactive forum but here goes...

I need a new Supercharger and can get a rebuilt one, but can not figure out how to corollate the cast numbers on the housings of the unit.

Seadoo part catalog shows part# that aren't close in length or sequence.
My originals are 867164 and 867151 - the one I'm looking at has 6867180 and 2422-3

Make any sense to anyone?
