Engine Compatibility
This screw is listed across many Mercury MerCruiser gasoline applications, including selected 4.3L MPI Alpha/Bravo, 5.0L MPI Alpha/Bravo, 350 MAG MPI, 350 MAG MPI Horizon, 377 MAG MPI Bravo, MX 6.2L MPI, MX 6.2L MPI Horizon, Black Scorpion, and 383 Stroker Scorpion packages, depending on serial range and assembly. Exact fitment should always be confirmed by engine model and serial number before ordering.

Serial Number Fitment Notice
Please confirm compatibility by your exact Mercury MerCruiser serial number and parts diagram before purchase. Small OEM hardware can be used in many assemblies, so exact serial-based lookup is the safest way to match the correct screw.

When This Part Needs Replacement
This screw is typically replaced when the original hardware is stripped, corroded, damaged during service, or missing during reassembly. Because Mercury uses this part across multiple engine families, replacing it with the exact OEM part number helps maintain proper fit and clamp load. This is a practical service inference based on its broad OEM usage.

Installation Notes
Install only the exact Mercury screw specified in the parts diagram for the assembly being serviced. Even when hardware looks similar, thread, length, head style, and intended location can differ between applications.

Parts Desk Insight
With OEM hardware, the details matter. A screw like this may look simple, but matching the exact Mercury number helps avoid using a fastener that threads in but is not quite right for the original assembly.
