I'm sure this has been covered but I can't find it. I have 93 SN, when driving I can hear a humming noise and when I speed up it goes away. Also with the boat out of water and in nutrual the prop still spends. Any ideas. Apologies if this has been covered somewhere.

The hum noise is probably the reduction gear transmission, hard to tell without hearing it. The prop spinning in neutral is referred to as a dirty neutral. It bares no real significance until it becomes an issue with docking/picking up skiers. To fix it means you have to rebuild transmission.
