This ski was run's fine about 3or 4weeks ago, since then the ski was sitting in a garage.
Now supercharger is seized and won't turn.
When engine started it had squeaky noise and smoke came out from cover. Motor was keep run but very poor feeling when open throttle. It found belt of supercharger was broken.

Supercharger belt was damaged because supercharger pulley didn't turn and cut by friction burned.
I checked supercharger pulley, it won't turn,
