Size: Compact design, typically with a 1.5-inch inlet/outlet diameter.

Grade: Marine-grade construction for saltwater and freshwater applications.

Viscosity: Suitable for low-viscosity fluids like seawater or freshwater.

Buoyancy: Not applicable (non-buoyant component).

Material: Housing made of corrosion-resistant materials like bronze or stainless steel; impeller often made of neoprene or nitrile rubber.

Flow Rate: Approximately 4-6 gallons per minute (GPM) at standard operating conditions.

Pressure Rating: Typically operates at low pressure (10-15 psi).

Compatibility: Designed for Yanmar 2GM marine diesel engines.

Seals/Gaskets: Viton or nitrile seals for durability in marine environments.

Maintenance: Requires periodic impeller replacement (every 1-2 years).
