Help for winterizing 2008yamaha SHO supercharger
 

I understand you have to drain water and run in upright position for 30 seconds.
Put stabilizer in gas.
Then Take off air cleaner and fog engine until it stops.
The store said you also have to fog the supercharger. How do you do that?

I am no expert on your pwc but a supercharger normally compresses intake air so if your spraying to fog the engine through the air inlet the supercharger would be fogged. Now there may be other maintanence that it needs which you could call a dealer to check on. I would call Brian @ Hudson Cycle and ask him.
