This washer is used in the water pump and driveshaft area of the lower unit. It helps maintain the correct stack-up of components in the pump assembly, supporting proper fitment of the housing, plate, impeller, and related hardware.

Because the washer is small and inexpensive, many technicians inspect or replace it during water pump service instead of reusing a worn, corroded, or distorted washer.
