Anyone who’s run a small propane outboard knows the simple joy of gear that just works. No fuss, no complicated fuel systems — just clean power and an easy start.

Performance & Practical Benefits

The first thing you’ll appreciate about this hose is how natural it feels to handle. It flexes easily without kinking, and the length gives you freedom to position the propane cylinder exactly where you want it — secure, stable, and out of the way. That might not sound like much, but once you’re underway, you’ll feel the difference. A good hose gives the whole setup a more balanced, steady feel.

The twist-on fittings make installation almost effortless. No wrestling with stubborn connections, no second guesses about whether it’s sealed properly. When it clicks into place, you feel that tight, confident grip that tells you the fuel connection is secure. And once your outboard is running, the hose maintains a smooth, consistent flow, helping the engine settle into its natural rhythm.

Durability matters, especially in a marine environment where sunlight, heat, and moisture test every component. This hose is built to stand up to all of it — long days on the water, repeated tank changes, and constant movement in a rocking boat. Over time, what you really notice is how little you have to think about it. No cracks, no stiffness, no leaks. Just a simple, dependable link between tank and motor.

Why Buy OEM

With fuel delivery, there’s no room for guesswork. A genuine Mercury Marine part is designed specifically for the pressure, flow, and safety requirements of the 5 horsepower propane outboard. Aftermarket hoses might look similar, but the differences in materials, fittings, and tolerances can lead to leaks, poor engine performance, or unsafe conditions.

Buying OEM means buying the exact hose Mercury engineered to run with your outboard — the right length, the right connectors, the right materials. It’s safer, more reliable, and built to last. It’s the kind of choice you make when you want your gear to work the first time, every time.
