🔌 Function

The lip seal seals the pump shaft inside the sea water pump body. It helps prevent water leakage from the pump and protects the bearing / shaft area from water intrusion.

Common signs of failure:

• Water leaking from the sea water pump body

• Corrosion or staining near pump shaft

• Pump rebuilt but shaft seal was not replaced

• Seal lip hardened, torn or distorted

• Reduced pump reliability after impeller service

• Replacement required during complete raw-water pump rebuild

📦 Condition

• Genuine Quicksilver part

• Brand new

• Supplied in original or equivalent packaging
