Mercury Quicksilver Retaining Ring 27290
A genuine Quicksilver OEM retaining ring for Mercury and MerCruiser assemblies, catalogued as 53-27290. Retaining rings are precision-fit components used to secure shafts, pins, bearings, and other rotating or sliding parts within their housings — the correct part number and fit are critical to safe, reliable operation.
Key Features
- Genuine Quicksilver OEM retaining ring
- Part number: 27290 / 53-27290
- Factory-spec dimensions and material
- Direct replacement for the original assembly position
Fitment & Application
Use this retaining ring where the Mercury or MerCruiser parts diagram specifies part number 27290 or 53-27290. Fitment varies by engine model, drive type, and serial number range — always confirm against your specific parts diagram before ordering.
When to Replace
Replace when the ring is deformed, cracked, corroded, or has lost its spring tension and can no longer seat securely in its groove. Retaining rings should always be replaced — not reused — after removal from a shaft or bore, as the removal process can compromise their holding force.
Installation Notes
Use the correct internal or external snap ring pliers for the ring type and groove orientation. Confirm the ring seats fully and flush in its groove before reassembly. Follow the Mercury service manual for the specific assembly sequence and any adjacent components that should be inspected or replaced at the same time.

Parts Desk Insights
Best use case: This retaining ring is the right choice when the Mercury or MerCruiser parts diagram calls out 53-27290 specifically. Retaining rings are sized to very tight tolerances — a ring that is even slightly too large or too small will not seat correctly and can fail under load. Always order by the exact diagram part number rather than trying to match by eye or caliper measurement alone, and plan to replace the ring any time the assembly is disassembled, since reusing a removed ring is not recommended.
