The Outboard Water Impeller is a crucial component in marine pumps, responsible for circulating cooling water to prevent engine overheating. It features flexible rubber vanes that rotate to draw water into the pump and push it through the cooling system. Regular inspection and replacement are essential to ensure optimal performance and avoid engine damage.

Size: Typically ranges from 1.5 to 4 inches in diameter.

Grade: Marine-grade materials, often compliant with ASTM or ISO standards.

Viscosity: Suitable for low to medium viscosity fluids (water, light oils).

Buoyancy: Neutral buoyancy in water, depending on material density.

Material: Nitrile rubber (NBR), neoprene, or EPDM for corrosion and wear resistance.

Operating Temperature: -20°C to 100°C (-4°F to 212°F), depending on material.

Pressure Rating: Typically 10-50 PSI, varies by design.

Flow Rate: 5-50 GPM (gallons per minute), depending on impeller size and pump design.

Compatibility: Resistant to saltwater, freshwater, and mild chemicals.

Lifespan: 1-3 years, depending on usage and maintenance.
