The Inboard Boat Impeller is a crucial component of marine pumps, designed to move water efficiently through the engine cooling system. It features a durable rubber or neoprene design with flexible vanes to ensure consistent water flow. Regular inspection and replacement are essential to prevent overheating and maintain optimal engine performance.

Size: Typically ranges from 3 to 12 inches in diameter.

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

Viscosity: Suitable for fluids with viscosities up to 500 cSt (centistokes).

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

Material: Commonly made from bronze, stainless steel, or composite polymers.

Operating Pressure: 50 to 150 PSI, depending on pump design.

Flow Rate: 50 to 1,500 GPM (gallons per minute).

Temperature Range: -20°F to 250°F (-29°C to 121°C).

Corrosion Resistance: High, especially in saltwater environments.

Impeller Type: Open, semi-open, or closed design for varying applications.

Shaft Compatibility: Standardized to fit marine engine or pump shafts.

Weight: Varies by size and material, typically 2 to 20 lbs.

Certifications: Often meets ABYC, USCG, or DNV standards.
