Mercury Quicksilver Washer 20583
A genuine Quicksilver OEM washer used across a wide range of Mercury, Mariner, MerCruiser, and Bravo assemblies. Catalogued as 12-20583, this small hardware washer provides proper fastening, spacing, or load distribution at the specific diagram position where it is called out. Because it appears in many different assemblies, the parts diagram is the most reliable way to confirm you have the right part.
Key Features

Engine & Drive Compatibility
This washer appears across many Mercury and MerCruiser parts diagrams, including select older Mercury / Mariner outboards, Bravo One / Two / Three sterndrives, Bravo XR / X drives, Blackhawk applications, integrated and high-performance transom assemblies, remote controls, and several older MerCruiser engine assemblies — depending on diagram location and serial number range.
Fitment Notice
Washer fitment depends on the exact engine, drive, transom assembly, control assembly, component group, and diagram position. Always confirm using your Mercury or MerCruiser serial number and the specific parts diagram before ordering — this washer appears in many different assemblies and the diagram location is the definitive match.
When to Replace
Replace when the washer is missing, corroded, bent, distorted, worn, or damaged during removal. Small hardware in a fastener stack should also be replaced when the assembly requires even clamping across the mating surfaces.
Installation Notes
Confirm the washer's exact position in the Mercury parts diagram before installation. Match it with the correct screw, bolt, nut, bracket, or linkage component for the assembly being serviced. Tighten related hardware to the torque specification in the Mercury service manual for your specific engine or drive.

Parts Desk Insights
Best use case: This washer is the right choice when the Mercury or MerCruiser parts diagram specifically calls out 12-20583 at a fastener, bracket, or linkage position. Its wide application range is actually the reason to be precise — because it shows up in so many different assemblies, matching by diagram location rather than by engine family or appearance is the only reliable way to confirm you have the right part. If you are servicing a Bravo drive, transom assembly, or older MerCruiser engine and the diagram shows 12-20583, this is your part.
