Mercury Quicksilver Two-Wire Retainer – Part No. 54676
This is a genuine OEM Mercury Marine / Quicksilver two-wire retainer clip used to secure and route pairs of wires within MerCruiser engine and sterndrive wiring harnesses. These small retention clips keep wiring organized, prevent chafing against hot or moving components, and maintain the factory harness routing that Mercury engineers for reliable long-term operation. Replace any retainer that is broken, missing, or deformed during engine service or harness repair.
Part Details
- Part Number: 54676
- Brand: Mercury Marine / Quicksilver
- Official Product Type: Two-Wire Retainer / Wiring Harness Clip
- System: Electrical / Wiring Harness — confirm diagram position for your application
- Condition: New OEM
Compatible Applications
- MerCruiser engine and sterndrive assemblies — specific harness position varies by model and serial number range
- Used wherever the Mercury parts diagram calls for a two-wire retainer at this part number
- Verify fitment using the Mercury parts diagram, engine model, and serial number before ordering
Installation Notes
- Route wires through the retainer following the original factory harness path
- Ensure the clip seats fully and locks securely — a loose retainer will allow wires to chafe or contact hot surfaces
- Replace all damaged or missing retainers in the harness during service — do not leave wires unsecured
- Refer to the Mercury service manual wiring diagram for correct routing and clip positions
Service Interval
Inspect wiring retainers during annual engine service or any time the harness is disturbed. Replace immediately if a retainer is cracked, broken, or missing. Unsecured wiring is a common source of intermittent electrical faults and chafe damage in marine engines.
Parts Desk Insights
Best use case: Harness repair, engine overhaul, or any service where wiring is disturbed and retainers are found broken or missing. Ordering a few extras is worthwhile — these clips are inexpensive and having spares on hand avoids a return trip for a small part that holds up a larger job.
Common mistakes: Skipping retainer replacement during harness work and leaving wires loose — this is a frequent cause of chafe faults and intermittent electrical issues that are difficult to diagnose later. Also confirm the part number from the diagram: Mercury uses several wire retainer styles (single-wire, two-wire, and multi-wire) that look similar but are not interchangeable.
