You screw it on, tighten it down, and forget about it until the next service interval. But the peace of mind it delivers? You’ll feel that every time your MerCruiser fires up smooth and strong.

Performance & Practical Benefits

There’s nothing quite like the steady feel of an engine that’s been well cared for. With the 8M0116379 installed, you’ll notice smoother startups thanks to the anti-drain-back valve that keeps vital oil where it belongs. No more dry, hesitant cranking—just confident, ready-to-run performance.

As you throttle up, the filter keeps contaminants from circulating through the system, maintaining tight oil pressure and helping your engine stay cool and consistent. Over time, this means less internal wear, better fuel efficiency, and an engine that feels strong even after years on the water.

The canister design makes servicing simple. Most boaters can swap the filter in minutes, and once it’s on, the corrosion-resistant shell stands up to moisture, spray, and long seasons. It’s one of those upgrades that quietly contributes to a reliable day on the water—steady, secure, and dependable.

Why Buy OEM

When it comes to filtration, shortcuts cost more than they save. Mercury OEM filters are engineered specifically for marine environments and for the oil flow demands of MerCruiser engines. Aftermarket filters may fit, but they rarely match the filtration media quality, shell strength, or valve performance.

Buying the genuine Mercury Marine part ensures you’re protecting the engine that carries you and your crew—season after season. It’s about doing the job right the first time and avoiding the headaches that come from guesswork. If you want long-term reliability and fewer surprises, OEM is the way to go.
