The Mercruiser 350 Water Pump is a marine-grade impeller pump designed for efficient water circulation in Mercruiser 350 engines. It ensures proper cooling by drawing raw water from the lake or ocean into the engine's cooling system. This durable pump is essential for preventing overheating and maintaining optimal engine performance in marine environments.

The Mercruiser 350 Water Pump is designed for marine applications with the following key specifications:

Size: Typically fits 5.7L (350 CID) engines, with a standard impeller diameter of approximately 3.5 inches.

Grade: Marine-grade construction for corrosion resistance and durability in saltwater/freshwater environments.

Viscosity: Compatible with standard marine engine coolants (ethylene or propylene glycol-based) at recommended viscosities.

Buoyancy: Not applicable (non-buoyant component).

Material: Housing is typically made of cast aluminum or stainless steel; impeller is nitrile rubber or neoprene for wear resistance.

Flow Rate: Varies by model but generally delivers 30-50 GPM (gallons per minute) at operating RPM.

Pressure Rating: Operates within 10-15 PSI under normal conditions.

Seal Type: Mechanical seal or lip seal to prevent coolant leakage.

Mounting: Bolt-on design with standard Mercruiser mounting patterns.

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