Installation and Maintenance

• Original Dimensions: The impeller measures 57x31x15 mm, ensuring a perfect fit in the pump housing to prevent leaks and pressure loss.
• Durable Material: Made from high-quality rubber resistant to saltwater, freshwater, and high temperatures.
• Easy Installation: Simple replacement allows for a quick return to the water without the need for specialized tools.
• Prevent Overheating: Regular impeller replacement protects the engine from damage caused by insufficient cooling.

A properly functioning water pump is essential for maintaining optimal engine operating temperature. We recommend regular inspection of the impeller condition, especially before the boating season. A worn impeller can cause reduced cooling performance, which in extreme cases leads to engine overheating. Replacing it with a new SIERRA 118-3081 impeller is an investment in the safety and longevity of your engine.
