Mercury – Water Separating Fuel Filter | Quicksilver Filtration Series | 10-Micron Element | 8M0146203

Overview

If you spend enough Saturdays on the water, you learn pretty quickly that clean fuel is the quiet hero behind every smooth start and steady run. There is nothing flashy about a fuel filter, but when it does its job right, you feel the difference immediately. The engine fires without hesitation, the throttle responds the way it should, and you never catch that uneasy sputter that can ruin an otherwise perfect morning. The Quicksilver 8M0146203 Water Separating Fuel Filter gives you that calm sense of reliability — the confidence that your engine is breathing clean, dry fuel no matter what the lake, river, or bay throws at you.

Performance & Practical Benefits

A good fuel filter is the kind of part you do not think about until you really need it — and that is exactly how it should be. This Quicksilver element spins into place with a tight, confident feel, and once installed, it delivers a steady supply of clean fuel that keeps your engine running smooth. You will notice the difference during long idle zones, in choppy water, and when you push the throttle wide open.

The ten-micron filtration captures the fine debris that often sneaks past lesser filters, and the water-separating design adds an extra layer of protection against contamination that can rob your engine of efficiency. It stands up to heat, vibration, and constant moisture, giving you season-long reliability with minimal upkeep. A simple once-a-year replacement is usually all it takes to keep your fuel system in top shape.

Why Buy OEM

With a part as critical as a fuel filter, cutting corners rarely pays off. A genuine Mercury Marine part number 8M0146203 gives you the filtration performance your engine was designed to run with. Aftermarket versions may look similar, but they almost never match the engineering behind Quicksilver’s materials, threading, or water-separation efficiency. When you choose OEM, you are choosing fewer clogs, fewer surprises, and more days on the water that go exactly as planned. For most boaters, that peace of mind is worth every penny.
