A well-maintained cooling system is essential for any outboard motor, and the Mercury Outboard Water Pump Impeller (47-19453T) is built to keep things running smoothly. Designed for 30-60 HP four-stroke Mercury engines, this impeller ensures a steady flow of water to prevent overheating and maintain peak efficiency.

Constructed from high-quality elastomers, this impeller is designed to withstand constant use, flexing and adapting to maintain optimal water circulation. Over time, impellers wear down due to friction and debris, reducing their ability to pump water effectively. Replacing it at regular intervals helps prevent costly engine damage and keeps performance consistent.

Key Advantages:

• Optimized for Mercury 30-60 HP Engines – Precision fit for efficient cooling and reliable operation.
• Durable, Marine-Grade Construction – Made from flexible, long-lasting elastomers that resist wear and environmental stress.
• Prevents Overheating – Maintains a consistent flow of water to regulate engine temperature.
• Straightforward Installation – Designed for easy replacement, keeping maintenance simple.

An overheating engine is never a good sign, and an old impeller is often the culprit. Regular replacements keep your outboard performing at its best, ensuring trouble-free days on the water.
