Attwood Gear Lube Pump For 32 oz Bottles is a hand-operated pump designed to transfer gear lubricant from a 32 oz (946 ml) bottle into the gearcase of a compatible outboard motor or sterndrive. It is used during lower unit gear oil changes, when fresh lubricant needs to be delivered from its bottle to the engine’s fill opening. The pump provides a way to move the oil through a hose instead of attempting to pour it into a small opening. For boat owners and marine technicians, it is a useful addition to the tools kept for routine engine maintenance.

The Attwood gear lube pump is designed for broad compatibility with outboards and sterndrives. Attwood describes it as a universal-fit pump intended to work with nearly any outboard or sterndrive, and the package includes one Yamaha adapter. This makes it relevant to buyers who maintain different types of marine engines or need an adapter for a compatible Yamaha application. Because gearcase connections can vary by engine model, check the fitting required by your specific outboard or sterndrive before use. The product packaging shows a pump assembly with a hose and a separate Yamaha adapter.

This marine gear oil pump is intended for 32 oz gear lube bottles, a size also commonly labelled as approximately 946 ml. That figure refers to the bottle the pump is designed to use; it does not indicate the oil capacity of your engine’s lower unit. Before servicing an engine, consult its manual for the correct gear lubricant, the required quantity and the recommended filling procedure. Gear lubricant is selected for the engine separately. The Attwood pump is the transfer tool used with the suitable bottle and engine connection.

During an oil change, a lower unit gear oil pump helps deliver lubricant from the bottle to the gearcase through its hose. This is particularly useful when the fill opening is positioned where pouring directly from a bottle would be awkward. The pump is described as easy to install, and its purpose is straightforward: connect the appropriate fitting, use it with a suitable 32 oz bottle and follow the engine manufacturer’s service instructions. It can be kept with other outboard or sterndrive maintenance supplies so it is available when the next gear oil change is due.

The Attwood Gear Lube Pump For 32 oz Bottles, model 11891D7, is intended for buyers looking for an outboard gear oil pump, sterndrive gear lube pump or lower unit gear oil pump. Its main purchasing points are the specified 32 oz bottle size, broad intended engine fit and included Yamaha adapter. If you already have the correct gear lubricant for your engine, check that its bottle and your gearcase connection suit this pump before starting the job.
