Impeller for Honda 9.9/15 HP Outboard Engine – CEF 500328 High-Quality Water Pump Impeller

This CEF 500328 impeller is designed for Honda 9.9 HP and 15 HP outboard engines, delivering reliable cooling system performance. Built to OEM specifications, it replaces Honda OEM part 19210-ZV4-013, ensuring a perfect fit and high efficiency. With this impeller, your engine will run at optimal temperature, which is crucial for long-term durability and trouble-free operation.

• Compatibility: Fits Honda BF9.9A and BF15A outboards (AH, AK, AM, AN series from the 1990s). This includes both short and long shaft versions of these engines. It’s an exact replacement for the original Honda impeller, making it ideal for older 9.9/15 HP models in need of maintenance.
• Use Cases: Ideal for small boats (3–5 m) powered by 9.9–15 HP engines – e.g., inflatable dinghies, small fishing boats, or auxiliary outboards on sailboats. This impeller keeps your motor cool during extended trolling speeds or quick runs to shore, ensuring your small boat’s engine remains reliable on the water.
• Maintenance: It is recommended to replace the impeller yearly or every 100 hours of operation (whichever comes first). Regular replacement prevents overheating and water pump failures. Always inspect the old impeller for cracks or stiffness and replace if any wear is noticed. Keeping up with impeller maintenance is critical to avoid engine overheating.
• Quality: Made from high-grade marine neoprene rubber, the impeller is resistant to saltwater and wear. Its 6-blade construction provides a smooth, consistent flow of cooling water. This ensures reliable engine performance even at high RPM or in hot weather conditions. The precision fit of this impeller restores your cooling system to factory performance, giving you confidence in your engine’s cooling.
• Recommendation: It’s good practice to carry a spare impeller on board. Small outboards are especially dependent on a functioning water pump – having this spare part ensures peace of mind and readiness for extended trips. By using a quality replacement like this, you protect your Honda engine and keep it running cool and efficient.
