Performance & Practical Benefits

Oil filtration may not be glamorous, but it’s absolutely essential—especially with engines as advanced and powerful as Mercury’s V12 Verado and 500 horsepower SeaPro. This filter provides a steady, secure and clean oil flow, helping your engine stay cool, smooth and protected through long days on the water.

You’ll notice cleaner oil between service intervals, fewer contaminants circulating through the system, and a more consistent feel at the helm. The anti-drain back valve is a small feature that makes a big difference: no more dry starts or hesitation when you first crank up. Everything stays lubricated the moment your engine turns over.

And because Mercury engineered this filter specifically for these high-output platforms, you’re not wrestling with fitment or guessing whether it’ll keep up. Installation stays simple, and the filter locks into place with the snug, precise feel you expect from genuine OEM parts.

Why Buy OEM

With an engine of this size and power, shortcuts don’t make sense. Mercury’s OEM filters are designed alongside the engines themselves, so every seal, thread and media layer lines up perfectly with factory specs. Aftermarket filters can look similar on the outside, but internal differences matter—especially when you’re dealing with high oil flow rates and extreme pressures.

Choosing Mercury OEM means long-term reliability, predictable maintenance, and the comfort of knowing your engine is protected exactly the way the manufacturer intended. It’s the kind of advice boaters pass along at the dock: buy the filter built for your engine, and don’t look back.
