A well-sealed cooling system is the key to keeping an outboard engine running at peak performance, and the Mercury Water Seal (26-884462) ensures just that. Designed to maintain a tight, leak-proof seal in Mercury and Mariner outboard engines, this OEM component prevents water from escaping where it shouldn’t, helping regulate engine temperature and protect critical components.

Crafted from high-quality, marine-grade materials, this seal is built to endure the relentless exposure to water, pressure, and temperature changes. Whether you're replacing a worn-out seal or tackling routine cooling system maintenance, ensuring a proper fit is essential to prevent overheating and long-term engine damage.

Key Benefits:

• Prevents Leaks & Overheating – Maintains a reliable seal, keeping the cooling system functioning efficiently.
• OEM Precision Fit – Manufactured to Mercury’s exact standards for seamless installation.
• Built for Durability – Resists wear, water intrusion, and temperature fluctuations.

Ignoring a worn water seal can lead to serious cooling system failures. Swapping it out as part of regular maintenance helps ensure smooth operation and extends the life of your engine, keeping you on the water longer.
