Installation and Maintenance Tips

• Original Quality: The SIERRA impeller is made from durable materials ensuring tightness and abrasion resistance.
• Safety: Prevents failures caused by lack of cooling, protecting the engine from costly repairs.
• Easy Installation: Simple design allows for home replacement, provided caution is exercised.
• Regulated Replacement: We recommend replacing the impeller every season or according to the engine manufacturer's guidelines.

When replacing the impeller, always check the condition of seals and the pump housing. Contaminants in the cooling system can accelerate the wear of the new impeller. After installation, test the system for leaks before heading out on the water. Remember that proper cooling function is the foundation of your engine's long lifespan.
