Type: Sealing Washer

Genuine Mercury Marine OEM sealing washer used in selected Mercury and MerCruiser control and shift-cable assemblies. Mercury parts diagrams identify this component as a "Washer – Sealing," installed alongside shift-cable hardware, cable guide, retaining nut, and related control components.
Compatible Applications
- Selected Mercury Marine and MerCruiser control / shift-cable assemblies
- Applications using guide kit 43433A01 and associated cable hardware
- Exact fitment must be confirmed against the correct model and serial-number parts diagram
System
Control / Shift-Cable Assembly — installed at the cable-to-helm or cable-to-drive interface to provide a seal at the assembly joint. Refer to the applicable Mercury parts diagram for exact position.
When to Replace
- Washer is flattened, distorted, cracked, or corroded
- Washer no longer seats or seals properly
- Any time the associated shift-cable or control assembly is disassembled for service
Service Interval
Inspect at every shift-cable or control-assembly service. Replace whenever the assembly is disassembled or if the washer shows any sign of deformation or damage.
Installation Notes
- Clean mating surfaces before installing the new washer
- Position the washer exactly as shown in the applicable Mercury parts diagram
- Inspect adjacent nut, guide, cable, and retaining hardware while the assembly is apart
- Fitment must be matched by part number and diagram location — not by appearance alone, as similar-looking washers are used across multiple marine assemblies

Parts Desk Insights
Best use case: This washer is the correct choice when servicing any Mercury or MerCruiser shift-cable or control-cable assembly where part number 8M0214950 (or its predecessor 815472) appears in the official parts diagram. It is a low-cost consumable that should be replaced as a matter of course any time the assembly is opened — skipping it is rarely worth the labor cost of a return visit.
Most common mistake: Ordering by appearance rather than part number. Similar-looking sealing washers appear in many different Mercury assemblies and are not interchangeable. Always verify the part number against your model's diagram before ordering.
Fitment guidance: If you are unsure whether 8M0214950 is the correct washer for your assembly, cross-reference the part number in the Mercury parts diagram for your specific model and serial number. If the diagram shows 815472, this current part (8M0214950) is the direct replacement.
