Outboard Engine Cooling System – Impeller, Water Pump & Thermostat
Cooling System for Outboard Engines – Impeller, Housing, Water Pump & Thermostat
A properly functioning cooling system is essential for optimal performance and to prevent overheating of your outboard engine. In our outboard engine cooling system category, you’ll find all essential components to keep your engine cool and safe: impellers, impeller housings, water pump repair kits, and thermostats.
The impeller pumps water through the engine to ensure correct cooling. The impeller housing holds the impeller in place and directs water efficiently through the engine. Water pump repair kits often include impeller, gaskets, and seals for easy and complete service. The thermostat regulates the engine’s operating temperature for optimal performance and long engine life. All parts are available for popular brands such as Suzuki, Yamaha, Mercury, Honda, Tohatsu, and Evinrude.
