The Mercruiser Gear Lube Pump is a marine pump designed to circulate lubricant in sterndrive systems. It ensures smooth operation and longevity of gears by maintaining proper lubrication. This pump is essential for preventing wear and overheating in marine engines.

The Mercruiser Gear Lube Pump is designed for marine applications with the following key specifications:

Size: Typically compact, with dimensions varying by model (e.g., 4-6 inches in length, 2-3 inches in width).

Grade: Marine-grade lubricant compatible with SAE 90 or SAE 80W-90 gear oil.

Viscosity: Optimized for high-pressure environments, typically 75W-90 or 80W-90 for smooth operation.

Buoyancy: Non-buoyant, designed for submerged or enclosed marine gear systems.

Material: Constructed from corrosion-resistant materials such as aluminum housing, stainless steel shafts, and nitrile rubber seals.

Flow Rate: Varies by model, typically between 1-3 gallons per minute (GPM).

Pressure Rating: Operates under moderate pressure, usually 10-30 PSI depending on application.

Compatibility: Suitable for Mercruiser sterndrive and inboard marine propulsion systems.
