Quicksilver Gear Lube & Oil Pumps

Quicksilver Gear Lube & Oil Pumps: OEM-Grade Protection for Your Marine Drive

When it comes to protecting the lower unit of an outboard motor or sterndrive, few names carry as much authority as Quicksilver. As the parts and accessories arm of Mercury Marine, Quicksilver products are manufactured by Mercury Marine and come from the P&A side of the company — meaning when you buy Quicksilver gear lube or an oil pump, you are getting genuine OEM-grade chemistry engineered by the same team that builds the engines themselves.

Why the Lower Unit Demands the Right Gear Lube

The gear case of an outboard or sterndrive is one of the most mechanically stressed areas on any boat. Submerged in water while spinning at high RPM and bearing full propeller loads, the gears inside are constantly fighting heat, friction, and potential water intrusion. Clean oil is essential in reducing friction and preventing damage to internal components, and Quicksilver's high-performance SAE 90 gear lube has been extensively tested to ensure impressive protection against corrosion and wear. It is specifically formulated to help prevent failures due to water entering the gear housing — one of the leading causes of costly lower unit damage.

Quicksilver High Performance Gear Lube SAE 90 is a synthetic blend formula designed for marine sterndrive and outboard lower unit gear cases. It works effectively in both freshwater and saltwater conditions, providing protection against metal-on-metal wear and water infiltration, with corrosion-resistant additives that handle harsh marine environments while maintaining performance in high-speed and high-horsepower applications rated 75 HP and above.

For applications requiring even greater performance, Quicksilver's 85W-90 Extreme Performance Gear Lube was designed for outboard and sterndrive racing applications. This makes the Quicksilver lineup suitable for everything from weekend cruisers to high-performance race boats.

The Quicksilver Gear Lube Pump: A Purpose-Built Service Tool

Changing gear lube is straightforward with the right tool, and that is exactly what the Quicksilver Gear Lube Pump delivers. The Quicksilver Gear Lube Pump is a tool designed to facilitate the process of adding or changing gear lube in boat lower units, particularly for outboard motors and sterndrives. It fits any outboard or sterndrive with a 3/8-16 drain plug, making it a nearly universal solution for DIY marine maintenance.

The Quicksilver lube pump is designed to fit a wide range of outboard and stern drive legs, including those manufactured by Mercury, Mariner, Honda, Johnson, Evinrude, Yamaha, Suzuki, and more. For added convenience, Quicksilver also offers a combination kit that bundles the gear lube and pump together — the Quicksilver 8M0222069 High Performance Gear Lube & Pump Kit includes a quart of Mercury Quicksilver High Performance Gear Lube and a gear lube pump, conveniently packaged together.

Cross-Brand Compatibility & Warranty Protection

Vessels with sterndrives from MerCruiser and outboard lower units from Mercury, Mariner, and Force can use Quicksilver premium gear lube to maintain their warranty coverage. Beyond those brands, Quicksilver marine lubricants are certified for use in all major marine engine brands. This broad compatibility means a single product can serve a mixed fleet or be used confidently on virtually any outboard at the dock.

Changing the gear lube at least once per season or every 100 hours of operation is recommended, whichever comes first. Keeping up with this interval — and using the correct lube — is one of the simplest ways to protect a significant mechanical investment.
