Lubricate front bearings every 50 hours or twice a year at minimum. The bearings are
lubricated through the hose in the engine room.
The boat should be lifted out of water when lubricating the rear bearings. It is advisable
to add grease to the rear bearings whenever the boat is lifted out of water. At minimum,
however, this should be done every 100 hours or twice a year.
