Quicksilver Nut 8267139 (2-Pack)
This 2-pack of genuine OEM nuts covers the most common scenario in marine service: you pull one fastener and realize you need a spare. These precision-threaded nuts are used throughout Mercury and MerCruiser engine and drive assemblies to secure critical components under vibration, heat, and load. Getting the right nut — correct thread pitch, material, and finish — matters in a marine environment where corrosion and fatigue are constant factors.

Common Applications
Use these nuts wherever the Mercury or MerCruiser parts diagram specifies part number 8267139. They appear across multiple engine families and drive configurations — always verify against your model’s current parts diagram, serial number, and assembly location before ordering.
When to Replace
Replace any time a nut shows signs of corrosion, thread damage, rounding, or deformation, or whenever it is removed from a critical fastened joint during service. In saltwater environments, it’s good practice to replace nuts any time they’re removed rather than reusing them.
Installation Notes
Follow the Mercury service manual for the correct torque specification and tightening sequence for the assembly you’re working on. Use appropriate tools to avoid over-tightening or thread damage. Apply anti-seize or locking compound only where specified by the service manual.

Parts Desk Insights
Best used as a direct OEM replacement during engine, drive, or powerhead service where the parts diagram calls for 8267139. The 2-pack format is ideal for service jobs where you’re replacing fasteners in pairs or want a backup on hand. Always order by part number from the diagram — nuts that look identical can differ in thread pitch, grade, or coating and may not provide the same clamping performance. If your assembly has been repowered or updated, cross-reference the current diagram to confirm this number hasn’t been superseded.
