Installation Notes

  1. Prepare the engine by running it for a few minutes to warm the oil, then shut it off.
  2. Place a drain pan under the old filter to catch any spills.
  3. Unscrew the old filter using an oil filter wrench. It will be full of oil, so handle carefully.
  4. Wipe the filter mounting surface on the engine clean with a lint-free rag.
  5. Apply a thin film of new engine oil to the gasket of the new filter.
  6. Screw the new filter on by hand until the gasket makes contact with the mounting surface.
  7. Tighten the filter an additional 3/4 to one full turn according to manufacturer specifications. Do not over-tighten.
  8. Refill the engine with the correct type and amount of new oil.
  9. Start the engine and check for leaks around the new filter. Shut off the engine and re-check the oil level, topping off if necessary.

Troubleshooting & FAQ

How do I find the right filter for my motor?

To ensure a perfect fit, check the part number on your current filter or in your engine’s service manual. You can also use the compatibility chart on this page by matching your engine's brand, model, horsepower, and year.

What is the difference between Mercury part 35-883701K01 and 35-877769K01?

The part number 35-877769K01 is the official superseded (replacement) part for the older 35-883701K01. They are functionally identical and fully interchangeable. This listing is compatible with both.

How often should this oil filter be replaced?

It is recommended to replace the oil filter every 100 hours of operation or at least once a year, whichever comes first. This should always be done as part of a complete oil change.

What are the symptoms of a clogged or failing oil filter?

Signs may include low oil pressure warnings, a decrease in engine performance, or unusually dirty/gritty oil during a change. A severely clogged filter can bypass unfiltered oil, leading to accelerated engine wear.

Is this filter for 4-stroke or 2-stroke engines?

This oil filter is specifically designed for 4-stroke outboard engines. It is not compatible with 2-stroke models.

OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
