Mercury – Water Separating Fuel Filter | High-Capacity Filtration | Marine-Grade Construction | 8M0154754

Overview

Every boater knows the feeling—slipping away from the dock, hearing the engine settle into a steady rhythm, and trusting that everything under the cowling is doing its job. Clean fuel plays a huge role in that peace of mind, especially on long runs where you can’t afford hesitation or roughness. That’s why having a reliable water separating filter isn’t optional; it’s essential. With the Mercury Marine part number 8M0154754 Water Separating Fuel Filter, you’ll know your Yamaha outboard is getting clean, dry fuel every time you hit the water. It’s a small part with a big responsibility, and it delivers exactly what boaters count on—steady performance and trouble-free days on the water.

Performance & Practical Benefits

You’ll feel the value of this filter in the way your engine behaves. That steady idle after a long run? That smooth acceleration when the chop picks up and you need to power through? Clean fuel makes all of it possible. The ten-micron element traps the fine contaminants that cause hesitation, poor throttle response and long-term wear. Meanwhile, the water-separating function keeps moisture out of places it absolutely doesn’t belong.

Fuel contaminated with even a little water can cause performance loss, corrosion and injector issues. This filter protects against those headaches by catching water before it can reach your engine. And because installation is so straightforward, most boaters can swap it out in minutes. A fresh, tight filter means a secure connection and reliable fuel flow—no drama, no guesswork.

Why Buy OEM

Choosing an OEM-grade filter like this one gives you the confidence that every detail matches factory specifications:

• Consistent filtration quality and proven engineering
• Longer-lasting internal components than many aftermarket options
• Better protection for expensive parts like injectors and fuel pumps
• Designed to deliver correct flow rates and pressure stability
• Built with the same standards Mercury applies to their own engines

When you’re counting on your boat to get you home, buying OEM isn’t just smart—it’s the right call.
