supercharger gone bad
I have about 78 hours on my ultra 250x and my supercharger is putting out like 8psi. Called r-rated performance and turns out that its usual for the s/c to go out and that pulley kits just speed up the process. Has anybody else had there s/c go out if so at how many hours?

Sounds more like a belt or boost leak. My exp. with bad sc's is usually been bearing related or total crash down failure. Is it making loud noise?

You know the SC that is on this boat has its origin in "land use" on cars. Hence, I can see why the SC unit may be having a hard time in a marine application. jb

When I bought my ultra last year in april (07), The kawi tech here drilled a small whole into the air intake hose going to the S/C and it just fits a straw from lube spray in there couple of shots in there then run the boat for a few revs and S/C still strong here at 129 hours. I've been doing this religously as we have a high salt content in our air here in Hawaii. Those who have not done this are experiencing simular issues (condensation and SC failure). Just a little 2cents.
