- Type: Washer
- Dimensions: .328 in. ID × .750 in. OD × .060 in. thick

What This Part Does
This genuine OEM washer provides load distribution, spacing, and fastener support in compatible Mercury outboard and MerCruiser sterndrive assemblies. At .328 in. ID × .750 in. OD × .060 in. thick, it appears across a wide range of diagram locations — from steering and control linkages to engine mounting, exhaust, and cooling system hardware.
The correct washer thickness and diameter directly affect clamping force and alignment in the assembly it supports. A washer that is slightly thicker, thinner, or narrower than specified can alter clamping load and affect how the assembly seats — use the OEM part rather than substituting a generic washer by appearance alone.
Compatible Applications
- Classic Mercury and Mariner outboard assemblies
- Early MerCruiser sterndrive assemblies
- Alpha and Bravo sterndrive applications
- Steering and remote control component groups
- Fuel, cooling, and exhaust component groups
- Engine mounting and bracket hardware
- Any Mercury or MerCruiser assembly where the parts diagram specifies 26825 / 12-26825
Always confirm the exact diagram location using your engine or drive serial number before ordering — this washer appears in many different assemblies.
Fitment Notice
Match part number 26825 / 12-26825 to the specific position in the Mercury or MerCruiser parts diagram for your engine or drive serial number. If the engine or drive has been repowered or updated, cross-reference the current diagram to confirm this number has not been superseded for your application.
When to Replace
- Washer is missing from the assembly
- Corrosion, bending, flattening, or distortion visible
- Washer no longer seats correctly in the fastener stack
- Assembly is being disassembled for service and hardware renewal is specified
Installation Notes
- Confirm the washer’s exact position in the Mercury parts diagram before installation
- Match with the correct screw, bolt, or nut for the assembly being serviced
- Tighten related fasteners to the torque specification in the Mercury service manual for your application

Parts Desk Insights
This washer has an unusually wide application range across Mercury and MerCruiser — the safest match is always the exact diagram location for your serial number rather than engine family alone. The most common issue is substituting a generic washer by visual size: dimensions matter in precision fastener stacks, and the .060 in. thickness is specific. If the diagram calls for 12-26825, use it as specified.
