Quicksilver High Performance Gear Lube for marine outboards and Mercruiser Sterndrive engines with gear cases above 75HP. This kit includes a reusable pump kit. Fits any outboard or stern drive with a 3/8"-16 drain screw. Note: not to be mixed 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 salt water 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.

The benefits of High Performance Gear Lube include:

Engineered to provide maximum protection for Sterndrive and outboard lower units.
Exclusive formula is engineered to provide extended gear life in extreme conditions including high-speed and high-horsepower applications.
Extensively tested to provide excellent protection against corrosion and excessive wear.
Specifically formulated to help prevent failures due to water entering the gear housing.
Extreme pressure synthetic additives protect gears from metal to metal contact.
Since no industry-wide standards exist concerning marine gear oils, it is essential to use products such as Mercury High-Performance Gear Lube which has been specifically designed and tested for marine applications.

Provides warranty protection for all Mercury Mercruiser Sterndrive and Mercury, Mariner and Force outboard lower units.

It is recommended that you change your gear lube at 50 hours for salt water use and at least once a year to ensure that the gearbox is free of water. If the prop seal has failed, water will enter the gear housing and cause fatal damage if lefty to stand during the winter.
