Performance & Practical Benefits

A good seal doesn’t draw attention — it just works. The 14077 Bearing Carrier Seal provides a tight, consistent barrier against water and debris while keeping the drive’s internal components lubricated and protected. Its rubber compound is designed to hold shape under heat and pressure, maintaining the seal’s integrity through long hours of running.

Replacing this seal at service time ensures smooth operation, cleaner gear oil, and a longer-lasting drive. It’s one of those simple maintenance steps that can save you from much bigger problems down the road — no leaks, no corrosion, just reliable protection.

Why Buy OEM

Aftermarket seals might look similar, but small differences in fit or material can lead to leaks or premature wear. The Quicksilver 14077 is a genuine Mercury Marine part, molded to exact tolerances that guarantee proper compression and sealing. It’s designed to handle the same load, heat, and vibration your drive sees every trip out.

Choosing OEM isn’t just about fit — it’s about peace of mind. This seal was built for your sterndrive, tested in the same harsh marine environments it will live in, and proven to perform. When you install Mercury parts, you’re not patching things together — you’re restoring your drive to factory condition.
