Fitment
Match this nut to your Mercury parts diagram using your engine model, serial number, and assembly location. Thread pitch, diameter, and finish vary across Mercury hardware — always confirm the part number before ordering.
When to Replace
Replace when the nut shows signs of corrosion, thread damage, or rounding, or when it has been removed during service and cannot be reliably retorqued to specification.
Installation
Clean threads on both the fastener and mating stud before installation. Follow the Mercury service manual for correct torque values, locking compound requirements, and reuse limits. Pair with the correct washer — see the Mercury MerCruiser Quicksilver Washer 12-8M0207778 for compatible hardware used in the same assemblies.
Parts Desk Insights
Best use case: This stainless nut is the go-to replacement during exhaust manifold, transom bracket, and stern drive mounting service on MerCruiser inboard and stern drive engines — anywhere corrosion resistance is non-negotiable and standard steel hardware would fail prematurely in saltwater or high-moisture conditions. Always replace with the OEM stainless specification rather than substituting generic hardware.
