The Mercruiser 3.0 Raw Water Pump is a marine-grade impeller pump designed for raw water cooling systems. Key specifications include:
Size: Typically fits 3.0L Mercruiser engines, with a housing diameter of approximately 4-5 inches.
Grade: Marine-grade construction for saltwater and freshwater use.
Viscosity: Compatible with standard marine cooling water viscosity; not designed for high-viscosity fluids.
Buoyancy: N/A (non-buoyant component).
Material: Housing made of corrosion-resistant aluminum or stainless steel; impeller typically composed of neoprene or nitrile rubber.
Flow Rate: Approximately 20-30 gallons per minute (GPM) depending on engine RPM.
Pressure Rating: Operates at low to moderate pressure (10-15 PSI).
Seals: Viton or silicone seals for durability in marine environments.
Mounting: Bolt-on design with standard Mercruiser mounting patterns.
Impeller Type: Flexible rubber vanes for self-priming and debris resistance.
