Performance & Practical Benefits

The Verado platform is known for its quiet power and effortless handling, but it can only shine when the engine oil is kept clean and circulating as it should. This filter steps in as a tough, dependable gatekeeper — capturing the debris, micro-contaminants, and tiny metal particles that don’t belong anywhere near a high-performance combustion chamber.

You’ll notice smooth startups thanks to the anti-drainback valve, which keeps the oil where it needs to be overnight or during long hours at the dock. At speed, the filter maintains steady oil flow, keeping your temperatures consistent and your engine running tight and refined. Installation is straightforward, and once the filter seats, it stays firmly sealed even during long runs in rough conditions.

Why Buy OEM

Every Verado engine is engineered with incredibly tight tolerances. Aftermarket filters simply can’t promise the same quality of filtration, structural integrity, or proper flow rate. Mercury’s OEM filter gives you exactly what the engine was designed to use — nothing more to guess, nothing to adjust, and nothing that compromises reliability.

If you’re the type who takes care of your boat so your boat can take care of you, sticking with OEM filters is the smartest move you can make.
