Impeller for Honda 9.9/15 HP Outboard Engines

This impeller is designed to replace the original water pump impeller on Honda 9.9 HP and 15 HP outboard engines, helping to maintain optimal cooling. Built to Honda's specifications, it restores the water pump’s ability to circulate coolant effectively through the engine. The six-blade design, made of durable marine-grade rubber, provides a steady flow of cooling water whether you’re idling during trolling or running at open throttle. By keeping your 9.9/15HP outboard's temperature in check, this impeller contributes to smooth performance and extends the engine’s service life.

Use Cases & Recommendations:

• Perfect for small inflatable boats, compact fishing skiffs, and sailboat auxiliary motors powered by Honda 9.9HP or 15HP engines, ensuring they remain properly cooled in all conditions.
• Maintains reliable cooling during low-speed trolling as well as full-throttle bursts, preventing the engine from overheating when it’s working hard.
• Recommended to replace the impeller each year or every 100 hours of use. Regular impeller replacement is a key step in outboard maintenance that helps avoid costly engine overheating and damage.
