Performance & Practical Benefits

Changing an oil filter isn’t glamorous, but the results are unmistakable. With the 8M0116378, the oil flows clean and steady, helping your engine stay cool, quiet, and protected. The thicker metal shell adds reassuring strength, especially if your boat lives in rough water or high-humidity conditions. You’ll notice smoother startups thanks to the anti-drain-back valve, which keeps the oil where it needs to be instead of letting it drain back into the pan. And because the filtration media is designed to trap more contaminants without restricting flow, your engine gets a steady supply of clean oil—tight, consistent, and reliable.

This all adds up to longer engine life, fewer surprises, and easier maintenance. The installation couldn’t be simpler: screw it on, tighten it down, and you’re back on the water with confidence.

Why Buy OEM

Choosing a Mercury OEM filter isn’t about brand loyalty—it’s about protecting the heart of your boat. Aftermarket options can miss the mark on filtration quality or shell thickness, and that can cost you far more in the long run. With this Mercury Marine part, you’re getting a filter designed specifically for your engine’s needs, tested in marine-grade conditions, and built for long-term reliability. It fits right the first time, removes contaminants efficiently, and gives you consistent performance season after season.

If you ask any seasoned boater, they'll tell you—some parts you don’t gamble on. Your oil filter is one of them.
