Performance & Practical Benefits

A good water separating filter isn’t just a “nice to have.” On a working boat—or any boat that sees fuel from different sources—it’s essential. This kit keeps your motor fed with clean, steady fuel, giving you smoother throttle response and preventing that uneven sputter you get when moisture or debris sneaks into the system.

The sight bowl makes checks quick and easy. One glance and you’ll know if there’s water at the bottom or particles starting to collect. The manual drain lets you clear it out in seconds. It’s the kind of simple, hands-on maintenance that keeps a hardworking SeaPro running tight and reliable.

Because everything in the kit is built to Mercury’s original equipment specs, installation is straightforward. The bracket fits cleanly, the fittings seat securely, and once it’s bolted down you’ll know it’s ready for the long haul—no leaks, no guesswork, no surprises.

Why Buy OEM

When you’re relying on an engine that’s built for demanding, high-hour use, the fuel system is not the place to experiment:

• Mercury OEM parts ensure proper filtration and flow
• Built to withstand commercial-grade duty cycles
• Designed for long-term corrosion resistance and reliability
• Ensures maintained engine warranties and peace of mind
• Fits right the first time—no modification, no improvisation

It’s the kind of part seasoned boaters recommend because they know how much trouble it prevents.
