Sierra

Sierra Gear & Lower Unit Lubes are marine lubricants formulated for compatible outboard and sterndrive lower unit and gearcase applications. Proper gearcase lubrication is an important part of routine marine maintenance and helps keep the applicable gear and bearing components supplied with the correct lubricant.

Sierra offers marine gear oils and lower unit lubricants in formulations and viscosities designed for specific marine applications. Choosing the correct lubricant is important because gearcase requirements can vary by engine manufacturer, model, drive system, and service specification.

Choose the Correct Lower Unit Lube

Before purchasing Sierra Gear & Lower Unit Lube, verify the manufacturer's recommended lubricant type, viscosity, application, gearcase model, and service specifications for your engine or sterndrive. Using the lubricant specified for the application is important for proper maintenance.

Keep your outboard or sterndrive gearcase properly serviced with the right marine lubricant. Shop Sierra Gear & Lower Unit Lubes at U.S. Boating & Marine Supplies.
