Service Interval
Replace at every oil change — typically every 100 hours or annually, whichever comes first. Also replace during seasonal service, winterization, or any time the filter shows corrosion, leakage, or physical damage.
Installation Notes
- Lightly coat the new filter gasket with clean engine oil.
- Thread the filter on by hand until the gasket contacts the sealing surface.
- Tighten per the engine service manual specification (do not over-tighten).
- Start the engine, check for leaks, shut down, and verify oil level before returning to service.
Parts Desk Insights
Best use case: Routine oil service on L6 Verado outboards — this is the correct OEM filter for the full 200–400 HP Verado L6 range and the 400R. It is the right choice any time you want a genuine Mercury part with no fitment guesswork.
Common mistakes: Matching by horsepower alone is not reliable across the Verado lineup. The L6 Verado and V8/V10 Verado platforms use different filters. Always cross-reference the engine serial number or the original filter part number — not just the HP rating — before ordering. Also note that 883701K01 is a superseded reference; 877769K01 is the current active part number.
