Mercury – Timing Belt | 15–20 HP Four-Stroke Series | Reinforced Marine Composite | 895120002

Overview
There’s something reassuring about a small outboard that runs clean and steady. You hear it in the smooth thrum at idle, that soft heartbeat of a motor that’s perfectly in sync. When you’re running a fifteen or twenty horsepower Mercury, the timing belt becomes one of those quiet heroes—working behind the scenes to keep everything aligned and predictable. A dependable belt gives you the comfort of knowing the engine will respond the same way every time you throttle up, whether you’re easing a skiff through mangroves at sunrise or shuttling family across calm afternoon water.

Performance & Practical Benefits
A strong timing belt changes the feel of your engine in ways you might not expect. You’ll notice smoother transitions from idle to midrange, more controlled acceleration, and a steady, predictable tone as the motor settles into its rhythm. This belt’s marine composite material resists stretching and moisture breakdown, keeping the timing tight even after long seasons of use.

For smaller outboards that spend their lives close to the waterline, durability matters. The reinforced teeth maintain their grip under heat and load, ensuring the camshaft turns exactly as it should. That precision means better efficiency, cleaner combustion, and fewer vibrations. It also protects the engine from the kind of mistiming issues that can shorten its life.

Installation is straightforward. Once the belt is tensioned correctly and seated on its pulleys, it locks into place with a secure feel. Routine replacement becomes one of those maintenance tasks that pays you back instantly—the moment you start the motor and hear it settle into a smooth, confident idle.

Why Buy OEM
A timing belt is not the place to experiment with aftermarket parts. Tooth spacing, material composition, tension limits—these details matter far more than most boaters realize. A genuine Mercury Marine part is engineered specifically for the 15–20 horsepower outboards, tested for long-term durability, and built to protect the engine from misfires or valve timing issues.

An OEM belt ensures proper synchronization, better longevity, and fewer surprises. If someone asked for advice dockside, you’d tell them the same—stick with the original design. It’s the safest and smartest choice.
