Installation Notes
- Make sure the engine is cool and place a drain pan beneath the existing oil filter.
- Use an appropriate filter wrench to remove the old filter. Some residual oil may spill during removal.
- Clean the filter-mounting surface with a lint-free rag and confirm that the old gasket has been removed.
- Lightly lubricate the new filter gasket with clean engine oil.
- Thread the new filter onto the mounting stud by hand until the gasket contacts the mounting surface.
- Tighten according to the engine manufacturer’s service instructions. Do not overtighten or use excessive force.
- Refill the engine with the manufacturer-specified oil to the correct level.
- Run the engine briefly and inspect the filter area for leaks. Stop the engine and correct any leak before operating the boat.
Troubleshooting & FAQ
How do I confirm that this filter fits my engine?
Match the engine brand, model or application, horsepower, 4-stroke configuration, year or serial-number condition, and the number printed on your existing filter. The 20mm x 1.5 thread is a useful specification check, but thread size alone does not confirm complete fitment.
Which manufacturer references does this filter replace?
The company product record identifies 35-822626Q04 and 8M162829 as the manufacturer references for this filter. Catalog information also lists 35-822626Q2, 35-877768K01, 35-822626K04, 35-822626T2, 35-8M0064104, and 35-8M0008397 within the same replacement group.
Is this an OEM filter?
No. This listing is for an aftermarket replacement oil filter. The manufacturer numbers shown on this page are reference numbers used to identify compatible applications; the filter itself is not sold as a genuine Mercury-branded component.
Does the package include an oil filter kit or multiple filters?
No. The package contains one individual aftermarket oil filter. Oil, tools, and other service parts are not included.
How often should I replace the oil filter?
Follow the maintenance interval in your engine manufacturer’s service information. Oil and filter service is commonly performed together, but the correct interval depends on the specific engine and operating conditions.
What should I do if the replacement filter leaks?
Stop the engine immediately, allow it to cool, and check that the old gasket was removed, the new gasket is seated correctly, and the filter was tightened according to the manufacturer’s instructions. Do not operate the engine while an oil leak is present.
Safety & Important Information
- Verify the complete engine application and existing filter number before ordering.
- Do not rely on horsepower alone; model, year, configuration, and serial-number conditions may affect fitment.
- This is an aftermarket replacement, not a genuine OEM component.
- Use the engine manufacturer’s service procedures and recommended oil when performing installation.
- Professional installation is recommended if you are unfamiliar with outboard maintenance.
