Marine Gear & Lower Unit Accessories

Proper marine lower unit maintenance requires the right fluids and tools to make gear oil changes clean, efficient, and hassle-free. Regularly servicing your outboard or sterndrive lower unit helps protect critical internal gears and bearings from corrosion, friction, wear, and water intrusion.

At US Boating Marine Supplies, you'll find the marine gear lube pumps, pump adapters, and lower unit accessories you need to simplify routine boat maintenance and keep your drivetrain properly lubricated.

Gear Lube Pumps

Marine gear lube pumps make changing outboard and sterndrive gear oil faster and cleaner. These convenient hand-operated pumps attach directly to standard quart or gallon gear-lube bottles and allow you to pump lubricant into the lower unit through the bottom drain/fill opening.

A quality lower unit oil pump helps reduce spills and mess while providing better control during gearcase servicing. Keep one in your boat maintenance toolbox for convenient, routine lower unit oil changes.

Pump Adapters

Lower unit pump adapters provide the proper connection between your gear lube pump and the drain/fill port on your outboard or sterndrive. Because drain plug and fill port threads can vary between manufacturers and models, selecting the correct adapter is essential for a secure connection and leak-free service.

Many American-made outboards use a 3/8"-16 threaded connection, while some Japanese outboard manufacturers use metric threads. Always verify the correct thread size and application for your specific engine before purchasing an adapter.
