Water pumps for boat motors are essential marine components that circulate cooling water to prevent engine overheating. These pumps are designed to withstand harsh saltwater and freshwater environments, ensuring reliable performance. They typically feature durable impellers and housings to handle continuous use and varying water conditions.

Size: Typically ranges from 2.5 to 6 inches in diameter.

Grade: Marine-grade, corrosion-resistant materials.

Viscosity: Compatible with fluids up to SAE 30W oil viscosity.

Buoyancy: Designed to operate in water with neutral buoyancy.

Material: Constructed from stainless steel, bronze, or reinforced thermoplastics.

Flow Rate: 500 to 5,000 gallons per hour (GPH).

Pressure Rating: 10 to 100 PSI, depending on application.

Power Source: 12V or 24V DC, or engine-driven.

Temperature Range: -20°F to 200°F (-29°C to 93°C).

Seal Type: Mechanical or lip seal for watertight operation.

Mounting: Bolt-on or flange-mounted for stability.

Impeller Type: Flexible or rigid, depending on pump design.
