propshaft seal

PROPSHAFT SEALS act as a barrier keeping water from getting into the gear chamber. During regular maintenance,

inspect the drained oil for signs of water that might have leaked in through a damaged prop shaft seal. If the drain oil is contaminated, you must repair the prop shaft seal before

launching the boat.
