Johnson/Evinrude 10-25 HP Outboard Impeller (CEF 500351)

This water pump impeller is crucial for maintaining proper cooling in your Johnson/Evinrude outboard. Specifically designed for older 10–25 HP models, it ensures an exact fit and performance equivalent to the original part, keeping your engine at optimal temperature with no overheating risk.

Manufactured by CEF Marine – a brand known for high-quality marine spares – the impeller uses a premium rubber compound that resists wear, saltwater, and heat. Replacing a worn impeller every 1–2 seasons is a key maintenance step to prevent overheating damage and to prolong your engine’s life.

• Ideal for Vintage Models: Suited for classic Johnson/Evinrude 10–25 HP engines (circa 1950s–1978) commonly found on small fishing boats, inflatables, and other compact vessels.
• Recommended Refresh: Great for restoring full pump efficiency in engines that have sat unused, as well as during annual tune-ups.
• Reliable Cooling: Ensures steady water circulation in both freshwater and saltwater, keeping engine operating temperatures safe.
• Precise Specs: Built to OEM dimensions (approx. 12.75 mm inner hub, 6 blades) to provide the correct water flow and pressure as the original impeller.
• Easy Installation: Directly replaces the old impeller with no modifications – it fits perfectly into the pump housing, making it feasible for DIY maintenance.
• Pro Tip: For optimal reliability, keep a spare impeller on board and replace at the first sign of wear or roughly every 100 running hours.
