Performance & Practical Benefits

A dependable oil cooler may not be glamorous, but its impact is undeniable.

The 8M0107033 maintains consistent oil cooling, helping reduce thermal stress on your engine and preventing the kinds of temperature swings that can shorten component life.

Its black anodized housing is more than just good-looking—it resists corrosion far better than untreated metals. Whether you boat in brackish marshes, freshwater lakes or open saltwater, the cooler stands up to harsh conditions without losing integrity. Fitment is precise and installation is straightforward when replacing the factory unit, making routine maintenance far less of a headache.

When your oil stays at the right temperature, the whole engine benefits. Lubrication stays reliable. Bearings stay protected. Performance stays crisp. You feel the engine respond the way it was meant to—smooth, predictable and ready for every push of the throttle.

Why Buy OEM

Boaters who know their engines stick with Mercury parts for a reason. An oil cooler is not the place to experiment with aftermarket shortcuts. Mercury’s engineering team builds each cooler to match the exact flow requirements and thermal characteristics of their engines. That means perfect fitment, proper temperature control and long-term durability. You won’t chase down leaks or odd heat fluctuations because the cooler wasn’t designed for your setup. With an OEM Mercury Marine part, you get reliability from the moment you bolt it in—and peace of mind every time you turn the key.
