Installation Notes

  1. Place a suitable drain pan beneath the existing oil filter to catch any spills.
  2. Using an oil filter wrench, turn the old filter counter-clockwise to loosen and remove it.
  3. Wipe the filter mounting base on the engine clean with a lint-free rag.
  4. Lightly lubricate the rubber gasket on the new filter with a thin film of clean engine oil.
  5. Carefully thread the new filter onto the mounting base. Spin it on by hand until the gasket makes contact.
  6. Tighten the filter an additional 3/4 to one full turn by hand. Do not use a wrench or overtighten.
  7. After installation, top off the engine oil, run the engine for a minute, and inspect for any leaks around the filter.

Troubleshooting & FAQ

How do I know if this oil filter fits my engine?

This filter is specifically for Mercury/Mariner 4-Stroke outboards (25-115 HP), primarily from years 1998–2008. The best way to ensure a match is to verify your engine model and year against our compatibility table and cross-reference your current filter's part number with the ones listed in our Part Number Matrix.

What is the difference between this filter and an OEM part?

This is an aftermarket filter engineered to meet or exceed original equipment manufacturer (OEM) specifications for fit, filtration, and performance. It provides a reliable, cost-effective alternative to the OEM-branded part.

How often should I replace my outboard oil filter?

Always follow the service intervals recommended by your engine's manufacturer. A general guideline for 4-stroke outboards is to replace the oil filter every 100 hours of operation or at least once a year, whichever occurs first.

What are signs of a clogged or failing oil filter?

Common symptoms include a low oil pressure alarm, a noticeable drop in engine performance, or engine oil that appears unusually dirty shortly after being changed. If you notice these signs, inspect and replace the filter promptly.

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.

Shipping speed & cost?

We ship worldwide quickly—typical transit 5–15 days. Standard shipping is free; expedited options appear at checkout where available.

Warranty & returns?

Covered by a 1-year warranty against manufacturing defects under normal use. If issues arise, contact support with your order details. Returns are accepted within our standard window (unused & in original condition). See our policy page or reach out for instructions.

Safety & Important Info

  • Verify images/specifications vs your original part. If anything differs—even if your model appears compatible—do not purchase.
