The Mercruiser 888 water pump is a marine pump designed for engine cooling systems. It ensures efficient water circulation to prevent overheating in marine engines. This durable pump is commonly used in Mercruiser sterndrive applications.

The Mercruiser 888 Water Pump is designed for marine applications with the following key specifications and technical properties:

Size: Typically fits Mercruiser 5.7L and 7.4L engines, with a standard impeller diameter of approximately 3.5 inches.

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

Viscosity: Compatible with standard marine engine coolants and water, no specific viscosity requirement for the pump itself.

Buoyancy: Not applicable, as the pump is a fixed component within the engine cooling system.

Material: Housing is typically made of corrosion-resistant aluminum or stainless steel, with a nitrile or neoprene impeller for wear resistance.

Flow Rate: Approximately 30-35 gallons per minute (GPM) at standard operating RPM.

Pressure Rating: Designed to handle standard marine cooling system pressures (typically 10-15 PSI).

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

Mounting: Bolt-on design compatible with Mercruiser stern drive systems.

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