Fuel that isn’t perfectly clean shows up as rough idle, lazy hole-shots, and clogged injectors. Swap in Mercury’s 35-8M0134466 fuel filter and let your Verado, FourStroke, or Pro XS breathe nothing but good gas. This OEM spin-on can replaces 8M0060041 and fits the standard Mercury/Quicksilver mounting heads found on most 75 hp–300 hp outboards.

• 10-micron, multi-layer media captures rust, varnish, and fine sand without starving the high-pressure pump.

• Built-in water trap collects droplets at the base; just crack the drain and keep fishing.

• Corrosion-proof nylon end caps handle 90 psi and 200 °F hot-soak temps.

• Comes with a new Viton® O-ring—no hunting for extra parts at service time.

Spin off the old can, wet the gasket, thread this one on hand-tight, prime the bulb, and you’re done. You’ll notice quicker starts, steadier mid-range pull, and the peace of mind that every gallon of 87 octane is reaching the rail clean and water-free—exactly how Mercury’s engineers planned it.
