Genuine OEM Stainless Steel Washer — Part 8M0204648
This genuine OEM stainless steel washer is built to the exact Mercury specification — 1.5 mm ID × 3.05 mm OD × 0.13 mm thick — ensuring the correct load distribution and corrosion resistance wherever part 8M0204648 is called out in your Mercury parts diagram. Stainless construction makes it the right choice for wet, saltwater, and high-vibration environments where standard steel hardware would corrode and fail.

Fitment
Match this washer to your Mercury parts diagram using your engine model, serial number, and assembly location. Always confirm the part number before ordering — washer dimensions vary across Mercury assemblies.
When to Replace
Replace when the washer shows signs of corrosion, deformation, or cracking, or whenever it is disturbed during disassembly and cannot be reliably reused to spec.
Installation
Clean the mating surfaces before installation. Follow the Mercury service manual for correct torque, orientation, and reuse limits. For the correct fastener to pair with this washer, see compatible nuts and screws in the same assembly diagram.
Parts Desk Insights
Best use case: This washer is most commonly needed during fuel system, carburetor, and throttle body service on MerCruiser inboard and stern drive engines — anywhere a small-diameter stainless washer is required to seat a fastener against a soft or precision-machined surface without corrosion risk. Always replace with the OEM stainless specification rather than substituting a generic hardware-store washer.
