Mercury MerCruiser Quicksilver Stainless Steel Anchor Pin Washer 89665

Mercury Marine stainless steel washer 89665 (service number 12-89665) is specified in select MerCruiser anchor-pin, trim-cylinder, and transom assemblies. Match the washer to the exact anchor-pin configuration instead of choosing a similar-looking washer by diameter alone.

Compatible Applications

  • Select MerCruiser Alpha One assemblies
  • Select Alpha One Gen II assemblies; two washers are shown in an applicable anchor-pin assembly diagram
  • Select Alpha One SS assemblies
  • Select TR and TRS sterndrive trim and transom assemblies where the diagram specifies 89665

Confirm the drive model, serial number, anchor-pin configuration, and parts diagram before ordering. Some 1.00-inch anchor-pin arrangements use different washers.

Service Guidance

Replace a washer that is bent, deeply worn, distorted, corroded, or damaged during disassembly. Inspect the associated anchor pin, bushings, and retaining hardware and follow the applicable Mercury service procedure during reassembly.

Technical FAQ

Will any washer of similar diameter fit? No. Check part number 89665, the anchor-pin arrangement, and the drive's serial-number-specific diagram.


Parts Desk Insights

Best use: Replacing the specified washer during compatible trim-cylinder or anchor-pin service. Common mistake: Assuming similar-looking trim hardware fits across drive generations. Sizing and fitment: Compare the approximate 33/64 in. inside diameter and exact part number to your drive's anchor-pin diagram before ordering.
