Mercury – Water Separating Fuel Filter | Yamaha-Compatible Series | Marine-Grade Construction | 8M0154752

Overview

If you spend enough time around docks and launch ramps, you’ll hear the same truth from every seasoned boater: clean fuel is everything. You can have the strongest engine on the water, but if your fuel system takes on water or debris, the day can go downhill fast. That’s why so many boat owners stick with a filter they genuinely trust. The Mercury Marine part number 8M0154752 Water Separating Fuel Filter gives you the kind of peace of mind that makes a long run feel easy—you know your fuel is clean, your engine is protected, and your day on the water won’t be cut short by something as avoidable as contaminated fuel.

Key Features

• Ten-micron filtration designed for more than ninety percent efficiency
• Built to separate harmful water from fuel before it reaches the engine
• Helps remove debris that can clog injectors or reduce engine power
• Direct replacement for Yamaha ABA-FUELF-IL-TR and Sierra 18-7945
• Simple, straightforward installation with a clean, secure fit

Engine & Boat Compatibility

This fuel filter is designed as a replacement component for select Yamaha outboard engines and works across several common setups:

• Yamaha outboards that use filters ABA-FUELF-IL-TR or ABB-FUELF-IL-TR
• Replaces Sierra 18-7945 filters often found in small to midsize outboards
• Ideal for fishing boats, runabouts, pontoons, skiffs, and inshore rigs
• Suitable for both portable tank systems and rigged fuel systems

Its broad compatibility makes it a smart choice for owners who run Yamaha outboards but prefer the reliability of a Mercury-engineered replacement filter.

Performance & Practical Benefits

On the water, a good fuel filter doesn’t just protect your engine—it changes how your boat feels. With cleaner fuel flowing freely, throttle response becomes smoother. Acceleration feels steadier. You won’t get that sputter or hesitation that sometimes hints at water or grit sneaking through a worn filter. The ten-micron element is tight enough to capture the small stuff that can cause big problems, yet open enough to keep fuel flowing without restriction.

This filter also does the quiet, steady job of separating out water, something every boater fights sooner or later. Condensation in tanks, a bad load of fuel at a remote marina, or rough seas sloshing into vented systems—it happens. The 8M0154752 gives you a layer of insurance against all of it. And when it’s time for seasonal maintenance, the swap is quick and simple—remove the old unit, spin on the new one, and you’re ready to go.

Why Buy OEM

• Designed to meet Mercury Marine’s exacting marine-grade standards
• Offers consistent filtration and long-term reliability in real-world conditions
• Helps protect your investment by preventing costly fuel-system damage
• More dependable than generic aftermarket filters with unknown tolerances
• Fits correctly the first time, avoiding leaks or loose connections

Replacing a filter might feel small, but it’s one of the smartest habits for keeping a Yamaha outboard running like it should.
