🔌 Function

Seals a rotating shaft, its flexible lip riding on the shaft surface to keep oil in and water out.

⚠️ Common Signs of Failure

• Water ingress into the drive oil, showing as a milky appearance
• Oil loss past the seal
• Seal lip hardened, cracked or worn flat
• Groove worn into the shaft where the lip runs
• Fishing line cut into the seal area

🛠️ Service Notes

• Check the shaft for a groove where the lip runs — a worn track will defeat a new seal immediately
• Fit the correct way round; a lip seal reversed will not hold pressure
• Fishing line wrapped behind a propeller is a common cause of failure here
