Engine Compatibility
This washer is primarily bell-housing and trim-sender configuration specific, rather than engine-displacement specific. Mercury and MerCruiser parts diagrams show it in select Bravo-style bell housing assemblies, including references where the washer is used with trim sender setups and where 8M0204685 replaces 806241.
Serial Number Fitment Notice
Bell housing hardware fitment depends on the exact drive model, transom assembly, trim sender configuration, bell housing version, and serial number range. Always confirm compatibility using the MerCruiser engine or drive serial number before ordering, especially where older 12-806241 has been replaced by 12-8M0204685.
When This Part Needs Replacement
Replace this washer if it is missing, corroded, distorted, worn, or damaged during bell housing, transom, trim sender, bellows, or related drive service. Small bell housing hardware should be replaced when condition is questionable to help avoid loose or uneven assembly fitment.
Installation Notes
Confirm the washer’s exact position in the bell housing diagram before installation. Many MerCruiser bell housing diagrams show this washer used in pairs, so check the required quantity for the specific assembly. Inspect related studs, inserts, O-rings, nuts, trim sender hardware, and bellows components while the area is apart.
