Engine Compatibility
This screw is listed across a broad range of 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, 5.7L MPI, 6.2L MPI, MX 6.2L MPI, and certain later crate and performance packages. Because Mercury uses the same hardware across many assemblies, exact fitment should still be confirmed by engine model and serial number.
Serial Number Fitment Notice
Please confirm compatibility by your exact Mercury MerCruiser serial number in the Mercury Parts Catalog before ordering. Mercury’s official catalog is organized by model and serial number for accurate parts lookup.
When This Part Needs Replacement
This screw is typically replaced when the original hardware is corroded, stripped, damaged during service, or missing during reassembly. Since it appears in many MPI and sterndrive-related engine applications, exact replacement with the correct OEM hardware helps maintain proper clamping and assembly fit. This is a practical service inference based on its broad OEM usage.
Installation Notes
Install only the exact Mercury screw specified for the assembly being serviced. With general hardware parts like this, thread, length, and application matter, so matching by part number and serial-number-based diagram is the safest approach.

Parts Desk Insight
Small OEM screws can look interchangeable, but on MerCruiser engines they are often reused across many different assemblies for a reason. Matching the exact Mercury number helps avoid thread mismatch, incorrect grip length, or hardware that looks close but does not seat quite right.
