Every seasoned boater knows the quiet anxiety that comes from wondering what’s moving through the fuel lines.

Performance & Practical Benefits

There’s a noticeable difference when your fuel system is protected by a proper separating filter. Engines that run clean run smoother—they idle more consistently, respond better when you throttle up, and maintain power without hesitation. The 8M0154762 uses a fine 20-micron element to capture the tiny debris that can accumulate over time, while also stripping out water that could trigger corrosion or cause sputtering under load.

In practice, that means a steadier, more confident ride. You’ll feel the engine stay tight and controlled when you’re pushing against wind chop, and you’ll notice fewer hiccups when shifting from idle to cruising speed. The filter threads cleanly and removes easily for service, making yearly maintenance a simple, low-stress routine. And when the season wraps up, you can winterize with the confidence that your fuel system is protected from lingering contamination.

Why Buy OEM

If you’re relying on your engine to get you offshore, OEM filtration isn’t just a preference—it’s a necessity.

• Built to Mercury Marine’s strict durability and efficiency standards
• Offers more consistent water separation performance than generic alternatives
• Designed for maximum filtration without restricting fuel flow
• Delivers long-term reliability and helps reduce costly engine wear
• Fits correctly the first time, reducing the chance of leaks or improper sealing

You wouldn’t skip an oil change, and you shouldn’t cut corners on filtration either.
