Anyone who has spent long days on the water knows that trust in your engine is built on the small things — the parts you rarely think about but rely on every mile.

Performance & Practical Benefits

With an oil tank, reliability matters just as much as capacity. This Mercury tank is built to stay secure, resist cracking, and maintain a tight seal even in rough chop or extended periods of high-rpm running. You’ll notice the difference in how steady your engine feels — smooth acceleration, consistent lubrication delivery, and fewer fluctuations in oil levels during long days on the water.

The integrated low-level sensor is a real advantage. Instead of guessing or waiting for performance dips, you get clear warning when it’s time to refill. That kind of early alert helps protect the heart of your engine, preventing wear and extending its life. The tank’s material has been tested against moisture, vibration, and chemical exposure, which means it resists degradation better than generic options. Installation is straightforward, and once it’s in place, it becomes one of those components you depend on without thinking twice — a secure, steady part of your engine’s daily rhythm.

Why Buy OEM

Genuine Mercury Marine parts aren’t just built to fit — they’re engineered for the realities of marine life. This oil tank is designed around the exact specifications of Mercury Diesel and OptiMax engines, providing the correct fit, the correct sensor output, and the correct durability. Aftermarket tanks often miss one of those details, leading to leaks, poor sensor function, or premature failure. With OEM parts, you get reliability that pays off for years. You install it once, and it works the way it should, every time you head off the dock.
