The Mercruiser Engine Water Pump is a critical marine component designed to circulate coolant and maintain optimal engine temperature. It ensures efficient cooling by drawing raw or freshwater through the engine's cooling system. Built for durability, it withstands harsh marine environments to prevent overheating and engine damage.

The Mercruiser Engine Water Pump and Marine Pumps typically feature the following key specifications and technical properties:

Size: Varies by model (commonly 3.5" to 5" diameter impeller).

Grade: Marine-grade components for corrosion resistance.

Viscosity: Compatible with standard marine engine coolants (ethylene/propylene glycol-based).

Buoyancy: N/A (not applicable for water pumps).

Material: Stainless steel, bronze, or composite housing; nitrile or neoprene impeller.

Flow Rate: 20-60 GPM (varies by engine size).

Pressure Rating: 10-30 PSI (depending on application).

Seal Type: Mechanical or lip seal for watertight operation.

Mounting: Bolt-on or direct drive (varies by engine model).

Compatibility: Designed for Mercruiser sterndrive and inboard engines.
