Bearing noise?.......
If it sounds a bit like bearing noise, that's fine. If seems all the older seadoo's have this sound. They sell a kit that is suppose to stop it but don't waste your money on it. Mine worked for about 1 hour. ......now it's back to the same sound.
If it's really bad, then you may have a bad bearing. If this has been sat up for a while, have you checked the pump oil?:cheers:
