Performance & Practical Benefits

A dependable oil filter makes a noticeable difference, even if you don’t always see it. With this filter in place, you’ll keep your engine oil cleaner longer—something you’ll feel in smoother operation, better throttle response, and reduced internal wear. Its fine 20-micron media captures smaller particles that can quietly grind away at bearings and internal surfaces if left unchecked.

The construction is solid and marine-ready, built for environments where humidity, vibration, and temperature swings are part of everyday life. Installation is simple and doesn’t require any specialized tools—just remove the old filter, seat the new gasket, and you’re back in business. It’s one of those small maintenance jobs that pays off through longer engine life and fewer surprises on the water.

Why Buy OEM

There’s a good reason seasoned boaters stick with OEM-grade parts, especially when it comes to filtration:

• Designed to meet Mercury Marine’s exacting specifications.
• More consistent filtration performance compared to many aftermarket filters.
• Better long-term protection against wear and oil degradation.
• Manufactured to handle marine-specific heat and vibration demands.
• Fits correctly the first time—no leaks, no misalignment, no headaches.

In short, you’re investing in the ongoing health of your engine, not just swapping a part.
