This ensures a care-free propeller shaft sealing.Being almost maintenance free the bearing takes care of a dry bilge for many, many years to come.
Water lubrication is provided by means of the exhaust water coming from the engine or through a separate water scoop. The unit is supplied complete with high quality silicone grease for the seals.
