This Quicksilver High-Performance Gear Lube with pump kit contains improved emulsifiers to help protect gears should water enter the gear housing and tackifiers to improve oil film adhesion to gears and internal components. For use with all Mercruiser Sterndrives and all outboard models.

Quicksilver High-Performance Gear Lube is designed for marine outboards and Mercruiser Sterndrive engines with gear cases above 20hp. Do not mix with Quicksilver Premium Gear Lube or any other gear lubricants.

It is always strongly recommended that the Gear Oil be checked and replaced after every 50 hours of saltwater use and before storage at the end of each season to prevent damage to the gearbox through water ingress through the propeller seal, should it have failed during the season.

Maximum protection for Sterndrive and outboard lower units.
Provides extended gear life in extreme conditions including high-speed and high-horsepower applications.
Excellent protection against corrosion and excessive wear.
