Fitment & Application
Use this washer where the Mercury or MerCruiser parts diagram specifies part number 20572 or 12-20572. Fitment varies by engine model, drive type, and serial number range — always confirm against your specific parts diagram before ordering.
When to Replace
Replace during disassembly or resealing work, or whenever the washer is crushed, deformed, corroded, or no longer providing a proper seating surface. Washers in high-load or water-exposed positions should be replaced rather than reused during service.
Installation Notes
Clean mating surfaces before installation. Replace any related seals or gaskets disturbed during disassembly. Follow the Mercury service manual for correct orientation, lubrication, tightening sequence, and torque specifications.

Parts Desk Insights
Best use case: This washer is the right choice when the Mercury or MerCruiser parts diagram calls out 12-20572 specifically and an OEM-spec fit is required. The 12- prefix in Mercury’s numbering system typically indicates a sealing or load-bearing washer — dimensions matter here, and a generic flat washer that is close but not exact in ID, OD, or thickness can affect clamp load or sealing in the assembly. Order by diagram position and confirm all three dimensions before substituting.
