Engine Compatibility
Published public listings for this part are light on full model-by-model fitment. The strongest supportable description is that 18323 is a Mercury MerCruiser keyed washer used in compatible assemblies that call for part 14-18323, including at least one application using carrier 73020C1. Because washer fitment is assembly-specific, the safest match is by exact Mercury or MerCruiser serial number and parts diagram rather than by engine family name alone.
Serial Number Fitment Notice
Mercury MerCruiser washer fitment can vary by assembly, production range, and component revision. Confirm part number 18323 against your exact engine or drive serial number in the Mercury Parts Catalog before ordering.
When This Part Needs Replacement
Replace this keyed washer when the original is bent, fatigued, damaged, corroded, or removed during service and no longer provides dependable locking or retention. It is also smart to replace it anytime the associated assembly is apart and the original tab washer has already been staked or reused.
Installation Notes
Install only after confirming the exact application by serial number and schematic. Because this is a keyed locking-style washer, orientation and fit against the related shaft, carrier, or retaining component matter. Reuse is not ideal if the original washer has been deformed during prior service. The cleanest approach is to match by the diagram for the exact assembly being repaired. This guidance is an inference based on the part’s keyed/tab washer function and Mercury’s serial-number catalog workflow.
Alternate/Superseded Part Numbers
Current public listings commonly show this part as 18323 or 14-18323. The clearest ordering reference remains Mercury MerCruiser Quicksilver 18323 / 14-18323.
Parts Desk Insight
Small locking washers like this are easy to overlook, but they often matter because the surrounding assembly depends on them to keep components from loosening in service. For older Mercury and MerCruiser repairs, matching the washer by the exact diagram is usually safer than ordering by appearance alone, especially when several similar keyed washers exist across nearby assemblies.
