Engine Compatibility
Compatibility should be confirmed by the exact engine model, drive model, and serial number before ordering. Relay assemblies are commonly application-specific within the electrical system, and exact part-number matching is the safest approach.
Serial Number Fitment Notice
Confirm fitment in the Mercury Parts Catalog by exact serial number before purchase. This is especially important with electrical components, where similar-looking relays may differ by circuit role, connector style, or mounting configuration.
When This Part Needs Replacement
Replace this relay assembly when the original unit is faulty, intermittent, corroded, heat-damaged, or no longer switching the circuit correctly during normal operation.
Installation Notes
Install only the exact relay assembly specified for the application being serviced. Electrical components should be matched by part number and serial-based diagram, not by appearance alone.
