Attwood Gear Lube Pump

Attwood Gear Lube Pump. A Simple, Universal Solution for Outboard and Sterndrive Maintenance

Changing the gear lube in an outboard or sterndrive is one of those routine maintenance tasks that makes a real difference in the long-term health of a marine drivetrain and having the right pump makes the job noticeably cleaner and easier. The Attwood Gear Lube Pump is a straightforward, affordable tool designed to fit the widest possible range of engines, so you can get the job done without hunting for a model-specific accessory.

Key Features

• Universal fit: Designed to work with nearly any outboard or sterndrive, making it a practical choice for boaters who own multiple engines or switch between brands.
• Sized for standard bottles: Built to work with a standard 32-ounce gear lube bottle which is the most common size available at marine supply stores, so there's no need to transfer fluid to a separate container.
• Yamaha adapter included: Comes with one Yamaha adapter right out of the box, extending compatibility to one of the most popular outboard brands on the water.
• Easy to install: Straightforward setup means less time preparing and more time on the water. A Quick Guide PDF is available to walk through the process.
• Affordable and practical: At a low price point, this pump is an easy addition to any onboard maintenance kit.

Who This Pump Is Best Suited For

This pump is a great fit for recreational boaters who handle their own engine maintenance and want a reliable, no-fuss tool to make gear lube changes cleaner and more controlled. Because of its near-universal compatibility, it's especially useful for marina staff, boat mechanics, or anyone servicing more than one type of engine. If the engine in question is a Yamaha outboard or any common sterndrive, this pump is very likely to work without any additional adapters.

It's worth noting that this pump is a manual hand pump intended specifically for transferring gear lube, it is not an electric bilge or ballast pump. If you're also looking to manage water aboard your vessel, Attwood makes a range of complementary products, including the Attwood Bilge Switch S3 Series and the Attwood Automatic Float Switch, which are designed for bilge water management.

What's in the Box

• 1 × Attwood Gear Lube Pump
• 1 × Yamaha adapter

The pump is sold as a single unit. If your engine requires a different brand-specific adapter, check your engine's service manual or the gear lube bottle threading before purchasing to confirm compatibility. Because the pump is designed for universal use, most standard outboard and sterndrive fittings should be accommodated without additional parts.

A Note on Safe Use

Gear lube is a chemical fluid, always follow the engine manufacturer's guidelines and the gear lube product's instructions when performing a fluid change. California residents should be aware that this product carries a Prop 65 warning; refer to the product documentation for details. Dispose of used gear lube responsibly in accordance with local regulations.
