🔌 Function

The seal closes the clearance between the propeller shaft and bearing carrier. It retains gear lubricant around the gears and bearings while preventing water and debris from entering through the propeller-shaft opening.

Common signs of failure:

• Gear lubricant leaking behind the propeller

• Fishing line wrapped around and damaging the seal lip

• Milky or water-contaminated drive lubricant

• Lower unit fails pressure or vacuum testing

• Gear-lubricant level drops between services
