Mercury 889706 is a genuine OEM washer used in select Mercury MerCruiser applications. Mercury parts sources identify it simply as WASHER, and the clearest application reference places it in a 400 Verado (4-Stroke, 6-cylinder) schematic at the lower adaptor plate. It should be matched by exact application rather than by appearance alone.

Engine Compatibility
The strongest fitment trail available ties 889706 to 400 Verado (4-Stroke, 6-cylinder) applications, specifically in the adaptor plate-lower area on engines 2B141124 and up. Because hardware items like washers can appear in multiple assemblies, fitment should still be confirmed by the exact engine model and serial number before ordering.
Serial Number Fitment Notice
Please confirm fitment by engine model and serial number before ordering. Mercury’s online parts catalog is the safest way to verify the exact diagram and callout for this washer.
When This Part Needs Replacement
Replace this washer when the original is damaged, distorted, corroded, worn, or missing, or anytime service work shows the hardware stack-up is no longer correct. This guidance follows the part’s role as an OEM hardware washer.
Installation Notes
Install only on the correct Mercury application and verify the removed part against the part number, serial number, and assembly location before ordering. Matching the original hardware exactly is the safest approach.
