- Remove the old filter and allow residual oil to drain. Clean the filter mounting surface with a lint-free cloth.
- Apply a thin film of clean engine oil to the gasket of the new filter.
- Thread the new filter onto the mounting base by hand. Tighten only according to the engine manufacturer's specified procedure; do not overtighten.

- Start the engine, inspect the filter area for leaks, and stop the engine immediately if leakage occurs.
- Dispose of the used oil and filter in accordance with local environmental regulations.
Troubleshooting & FAQ
How do I confirm this filter fits my engine?
Compare your engine's complete model designation, horsepower, stroke, year, and serial-number range with the compatibility information and service manual. The part number on the filter currently installed on your engine is also useful for comparison. Contact support with the full engine identification if you are uncertain.
Is this an OEM filter?
No. This listing is for an aftermarket replacement filter. Mercury, Yamaha, and other manufacturer names and part numbers are used only to identify compatible references and applications.
How often should the filter be replaced?
Follow the maintenance interval specified in your engine owner's or service manual. Filter replacement is normally performed as part of an engine-oil service, but the correct interval varies by engine model and operating conditions.
Can this filter be used with synthetic oil?
Use only the oil type and viscosity approved for your specific engine. Filter compatibility should be confirmed by the part number and application, not by oil type alone.
Do I need a special tool?
A filter wrench may be useful for removing a tight old filter. Install the new filter by hand unless the engine manufacturer's instructions specify a particular tool or tightening method.
What should I do if the new filter leaks?
Stop the engine immediately. Check that the old gasket was removed, the mounting surface is clean, and the new filter is correctly seated and tightened according to the service manual. Do not operate the engine until the leak is resolved.
