The Mercruiser 5.7 Circulating Water Pump is designed for marine applications with the following key specifications and technical properties:
Size: Typically fits 5.7L (350ci) Mercruiser engines, with mounting dimensions specific to OEM configurations.
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 viscosity levels (typically 50/50 mix with water).
Buoyancy: Not applicable (non-buoyant component).
Material: Housing is typically cast aluminum or stainless steel; impeller is made of neoprene, rubber, or composite materials for wear resistance.
Flow Rate: Designed to circulate coolant at a rate suitable for engine cooling (varies by model and RPM).
Seals: Utilizes high-quality lip seals or mechanical seals to prevent leaks.
Operating Temperature: Rated for standard marine engine operating ranges (up to 200°F/93°C).
Compatibility: Works with Mercruiser 5.7L engines and compatible cooling systems.
