Gear & Lower Unit Lubes

Marine Gear & Lower Unit Lubes

Marine gear and lower unit lubes are specially formulated lubricants designed to protect the gears, bearings, shafts, and other critical components inside outboard motors and sterndrives. These marine-grade lubricants are engineered for the demanding conditions found in boat gearcases, where water exposure, pressure, heat, and heavy loads can accelerate wear.

Unlike standard automotive gear oils, marine lower unit oils contain specialized additives that help maintain lubrication and film strength while providing protection against corrosion, wear, and water intrusion. Using the correct outboard lower unit lubricant helps keep your gearcase operating smoothly and can extend the service life of expensive internal components.

At US Boating Marine Supplies, you can find quality marine gear oil, lower unit lube, and sterndrive lubricants to help protect your boat's drivetrain and keep your motor performing reliably on the water.
