Serial Number Fitment Notice

Oil filter fitment can vary by engine model, production year, adapter style, and serial number. Always confirm 8M0116378 against your MerCruiser engine serial number, original filter, or Mercury parts diagram before ordering.

When This Part Needs Replacement

Replace the oil filter during scheduled oil changes, seasonal service, winterization, or any time the filter is damaged, corroded, leaking, restricted, or overdue for maintenance. A clean oil filter helps reduce abrasive contaminants in the lubrication system and supports longer engine life.

Installation Notes

Lightly oil the new filter gasket before installation, spin the filter on until the gasket contacts the sealing surface, then tighten according to the engine service manual. After installation, run the engine, inspect carefully for leaks, shut down, and recheck the oil level before returning the engine to service.

Parts Desk Insight

This filter is tied to Ford-based MerCruiser inboard and sterndrive engines, so the safest match is by engine serial number and original filter reference rather than engine displacement alone. Many Ford marine V8 applications look similar, but adapter style and production details can still affect the correct filter choice.
