Mercury – Remote Water-Separating Fuel Filter Kit | Fuel System Protection | Marine-Grade Components | 8M0109543

Overview

If you spend enough time on the water, you learn quickly that fuel quality can make or break a day. A little moisture, a bit of debris — that’s all it takes to turn a smooth run into a frustrating afternoon drifting in the wind. That’s why boaters who rely on their engines trust a solid water-separating system. This Quicksilver Remote Water-Separating Fuel Filter Kit gives you that peace of mind.

Performance & Practical Benefits

Clean fuel is the heartbeat of any marine engine. When this kit is installed, you’ll notice how steady and reliable your engine feels, even after long periods between fill-ups. The 10-micron filter catches the smallest particles before they cause hesitation or rough idling, while the water-separating bowl gives you a clear, easy way to check for contamination at a glance.

Throttle response feels smoother, especially under load, because the fuel system stays free of water pockets and debris. The components mount securely, giving you a tight, confident fit that holds up against vibration and constant motion. Routine maintenance becomes easier, too — you can see changes in fuel quality before they become real problems, and replacing the filter is quick and clean. Everything about this kit is designed to protect your engine while keeping the experience of boating simple and predictable.

Why Buy OEM

When fuel quality is involved, cutting corners never pays off. Using a genuine Mercury Marine part like 8M0109543 ensures every component — from the clear bowl to the WIF sensor — is engineered specifically for your FourStroke outboard. Aftermarket kits might look similar, but they rarely offer the same precision, durability, or compatibility with Mercury’s electrical systems. With OEM, you get parts that fit right the first time, last longer, and give you fewer surprises. It’s the kind of reliability seasoned boaters swear by, because it means more time on the water and less time troubleshooting.
