What This Shift Shaft Seal is Used For
This shift shaft seal is installed in the lower unit to seal around the shift shaft where it passes through the gearcase housing or seal carrier.
A properly sealing shift shaft seal helps keep water out of the lower unit and helps keep gear lubricant inside the gearcase during operation.
Shift shaft seals are commonly replaced during lower unit resealing, water intrusion repair, shift shaft service, or complete gearcase rebuilds.
Replacing worn, hardened, or leaking seals can help protect internal gears, bearings, and shafts from water-contaminated gear lube.
