Performance & Practical Benefits

A good portable tank should disappear into the routine—steady fuel delivery, no leaks, no swelling in the sun, no odd smells drifting around the cockpit. This Mercury Marine part checks every box. The blow-molded body feels tight and solid, even when the tank is full and the chop kicks up. The carry handle has a secure shape that makes it comfortable to move across a dock or trailer.

The integrated gauge is one of those little details you don’t realize you’ll appreciate until you have it. A quick glance tells you exactly what you’ve got left, so you aren't guessing halfway across the lake. The diurnal cap and fuel demand valve help manage pressure and prevent vapor escape, keeping everything running smoother and cleaner—especially during hot-weather outings.

Because it’s built to Mercury Marine standards, the fittings line up cleanly and the flow stays smooth, even with extended running or frequent stop-and-go operation. Simply put, it’s the kind of tank that earns your trust one trip at a time.

Why Buy OEM

There’s a big difference between a generic portable tank and one designed specifically around marine use. Mercury Marine parts are engineered for real-world boating—not lawn equipment, not general hardware shelves. You’ll get long-term durability, reliable venting, and fittings that match your fuel system the way they’re supposed to. An OEM tank saves time, avoids leaks, and won’t leave you wondering whether the issue is “just the tank.” When it comes to fuel, that peace of mind is worth every penny.
