Performance & Real-World Benefits

The 823534 filter keeps your fuel system healthy by catching contaminants before they can clog your carburetor or injectors. Even a small amount of debris can cause poor starting or fuel starvation — this simple inline filter helps prevent all that.

It’s easy to inspect, easy to replace, and built to hold up against vibration and ethanol-blended fuels. Replacing it regularly is one of the simplest ways to extend the life of your outboard.

Why Choose OEM

Mercury’s OEM filters are precision-made to flow the right amount of fuel while blocking contaminants efficiently. Aftermarket filters might restrict flow or break down faster when exposed to ethanol or water.

A genuine Quicksilver filter ensures your engine gets the clean fuel it needs, every time you squeeze the primer bulb.
