Mercury – Fuel Filter Element | Inline / Under-Cowl Filtration | Two Micron Protection | 8M0122423

Overview

Every boater has felt it—the way an engine hesitates for half a second and your stomach drops right with it. Most of the time it is not something major. It is just fuel that is not as clean as your engine deserves. When you spend your weekends on the water, you learn quickly that dependable power is not just about horsepower; it is about consistency, smoothness, and trust. That is why a solid fuel filter becomes more than a maintenance item. It becomes an insurance policy for your day on the water.

The Quicksilver 8M0122423 Fuel Filter Element is designed for boaters who want their Mercury engine to breathe clean fuel every single time. Built for a long list of Mercury outboards and MerCruiser sterndrive engines, it filters out the fine particles and moisture that quietly chip away at power, efficiency, and throttle response. With this filter in place, your engine simply feels better—steady, smooth, and ready for whatever the day brings.

Performance & Practical Benefits

A clean fuel system changes the entire feel of your boat. You get sharper throttle response, smoother idle, and steadier power when climbing onto plane. This filter’s two micron element captures the tiny debris that ordinary fuel pumps and injectors simply cannot tolerate. As a result, the engine runs cleaner and stays protected—even when you encounter questionable marina gas or carry fuel for long periods in warm weather.

Because the filter sits under the cowl or inside the housing, installation stays clean and simple. The screw-in style design gives a snug, secure fit that will not rattle loose or allow bypass flow. And since the element meets Mercury’s own requirements, you can trust it to deliver the steady, reliable filtration your engine needs during long days offshore or slow trolling runs at sunset.
