Serial Number Fitment Notice
Oil filter fitment can vary by engine family, Verado generation, horsepower, and serial number. Always confirm 877769K01 / 35-877769K01 against your Mercury engine serial number, owner's manual, original filter, or 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, or overdue for maintenance. A clean oil filter helps protect internal engine components from abrasive contaminants and supports reliable long-term engine operation.
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, check carefully for leaks, shut down, and recheck the oil level before returning the engine to service.

Parts Desk Insight
This filter is specific to Mercury's L6 Verado platform, so horsepower alone is not the safest way to match it. Confirming the engine serial number and original filter reference is the best check, especially across 200–400 HP Verado and 400R applications.
