Engineered Marine Products 47-47273 Water Pump Impeller Impellers

The Engineered Marine Products 47-47273 is a replacement water pump impeller designed for marine cooling system applications. Impellers are a critical component of raw-water cooling systems found on inboard and sterndrive engines, circulating water through the engine to prevent overheating.

Key Features:

• Direct-fit replacement impeller engineered to OEM specifications
• Flexible rubber vanes designed to move water efficiently through the pump housing
• Corrosion-resistant construction suited for freshwater and saltwater environments
• Maintains proper coolant flow to protect engine components from heat damage
• Manufactured by Engineered Marine Products, a trusted supplier of marine cooling system components

Regular impeller replacement is essential preventive maintenance for any marine engine. Over time, rubber vanes can crack, stiffen, or break — especially after dry running — leading to loss of cooling flow and potential engine damage. The 47-47273 impeller is built to restore proper pump performance and keep your engine running at safe operating temperatures.
