Mercury – Water Separating Fuel Filter | Marine Filtration Series | High-Efficiency Element | 8M0154766

Overview

There’s a certain comfort that settles in when you know your engine is running on clean, dependable fuel. It’s that quiet confidence you feel when you ease away from the dock at sunrise, or when you push the throttle a little harder heading toward open water. The Quicksilver 8M0154766 Water Separating Fuel Filter is one of those behind-the-scenes parts that keeps your time on the water smooth and predictable. You don’t notice it when it’s working — and that’s exactly the point. It protects your Yamaha outboard from the things you don’t want to think about: water in the fuel, fine debris, and the slow wear that sneaks up on engines over time.

Performance & Practical Benefits

On the water, a clean fuel system can make the difference between a good day and one cut short. The 8M0154766 filter is built with dense, high-efficiency media designed to catch the small particles that cause clogged injectors, rough running, or poor throttle response. You’ll notice smoother idle, more predictable power delivery, and fewer surprises when you shift or accelerate.

But where this filter really earns its keep is in separating water — a constant threat in marine environments. Condensation, venting, and fuel dock variability all introduce moisture into your fuel supply. This filter helps pull that water out before it ever touches your engine. That translates into steadier performance, better fuel economy, and long-term protection of your internal components.

Installation is straightforward, which makes yearly replacement simple. And because it’s designed to match OEM specifications, you get the right fit and the right flow every time.

Why Buy OEM

Choosing an OEM-grade filter is about more than convenience — it’s about protecting your investment. With a Mercury Marine part, you know:

• It’s built to strict quality and durability standards
• Fitment is consistent and reliable
• It offers long-term value through better engine protection
• You avoid the uncertainty and inconsistency of cheaper aftermarket parts
• It’s engineered to perform from the first turn of the key

This is the kind of filter seasoned boaters stick with because it removes the guesswork from an important maintenance step.
