Stock SC very loud. What gives?
I have a ski that has a louder than normal SC whine. The SC is stock and the bearings are in good shape and have fresh washers. For some reason it whines louder than normal and when the SC is bolted in you can't feel any lash in the drive gear. I know that neither of these is normal. I talked to a few people and tried shimming the SC away from the PTO by 2mm. No luck. I don't feel comfortable letting this ski go knowing there's something wrong. Any ideas?

How many teeth are on the SC drive gear? Could you have an 185-hp gear by mistake? It's 1 tooth larger... Ron

This is the original charger and flywheel. It's the stock 16 tooth gear.

Sounds like possibly a SC bearing... how many hours on it???

i think around 60 hours. The bearings look good. I tried another stock 06 SC and same results. The whine on this thing would make a Rude sound quiet.

Pulled the SC and held my hand over the SC hole to cacth oil spray. Fired it up and the sound was gone. I promise you i'm not going crazy! it's WAY louder than it should be and there's no lash in the gears whatsoever. I'm about to pull the engine and pto cover. I think if i let this thing go something spinning very fast is going to find it's way out of the PTO cover.
