Mercury Premium Gear Lube
For the gearboxes of all Mercury, Mariner and Force outboards. Do not use this product for OMC electric gear cases.
Mercury Premium Gear Lube is a proprietary formula designed to provide excellent lubrication and corrosion protection for lower gears in high and low horsepower engines under a variety of conditions.
- Improved emulsifiers for gear protection in the event of water entering the gearbox.
- Sticking agents improving the adhesion of the oil film to gears and internal components.
- Gear protection additives against metal-to-metal contact and excessive wear.
Changing the lubricant annually (before wintering) or every 100 hours of operation under normal use (50 hours in seawater) is recommended. Please refer to the owner’s manual.
