Size: 3.0 Mercruiser impeller typically measures 3.5 inches in diameter.
Grade: Marine-grade rubber or neoprene material.
Viscosity: Designed for use with marine engine coolant or raw water, viscosity varies based on operating temperature.
Buoyancy: Not applicable, as impellers are submerged and non-buoyant.
Material: Nitrile rubber (NBR) or ethylene propylene diene monomer (EPDM) for corrosion resistance.
Blade Count: Typically 6-12 flexible vanes for optimal water flow.
Operating Temperature Range: -20°F to 250°F (-29°C to 121°C).
Compatibility: Fits 3.0L Mercruiser stern drive and inboard marine engines.
Rotation: Clockwise or counterclockwise, depending on pump design.
Pressure Rating: Handles up to 30 PSI in standard marine cooling systems.
