Performance & Practical Benefits

A fuel tank is one of those pieces of gear you don’t think much about—until it gives you problems. That’s why it’s worth choosing one that feels sturdy in your hands and stays dependable season after season. The blow-molded body of this tank has a tight, rigid feel that doesn’t flex or bow when filled, and the UV protection helps it hold up under long afternoons in direct sun.

The integrated fuel gauge offers a simple, steady readout, eliminating guesswork when you’re planning how far you can run. The fuel demand valve adds another layer of protection by preventing pressure-related flooding, keeping the engine feed smooth and controlled. You’ll notice the difference in real-world use; everything feels cleaner and more predictable. Whether you’re running a portable outboard on a quiet lake or powering a tender at the marina, the experience is consistent—secure, smooth, and reassuring.

Why Buy OEM

Choosing a genuine Mercury Marine part means you’re buying components that match the standards your engine was built around. An aftermarket tank may look similar, but the materials, caps, valves, and fittings can vary more than you think. With an OEM product, you get predictable performance, long-term durability, and safety features designed specifically for marine environments. It’s the kind of dependable choice seasoned boaters make—not because it’s flashy, but because it works right the first time and keeps working.
