Overview

The Attwood Marine 11891D7 is a gear lube pump for 32-ounce bottles that fits nearly any outboard or sterndrive and includes one Yamaha adapter. It is a straightforward service tool for routine gear lube changes when you need to move lubricant from the bottle into the drive without trying to pour it directly.

For boat owners who handle their own maintenance, the main fit points are simple: it is made around the common 32-ounce gear lube bottle format, and it covers a wide range of outboard and sterndrive applications. The included Yamaha adapter adds another connection option for engines that need it.

Key features

• Made for use with 32-ounce gear lube bottles
• Fits nearly any outboard or sterndrive for broad service compatibility
• Includes one Yamaha adapter for engines that use that connection style
• Easy to install for routine gear lube changes

Compatibility and fit

This pump is a good match for owners servicing outboard and sterndrive drives where a bottle-fed hand pump is the practical way to refill gear lube. Before ordering, the two checks that matter are your bottle size and whether your engine uses the included Yamaha adapter or a connection already covered by the pump.

It also makes sense for owners maintaining more than one boat or engine type, since the pump is built for near-universal fit across this category rather than a single make and model.

Routine service use

This is the kind of maintenance tool that fits seasonal service, pre-storage prep, and mid-season lower unit oil changes. It suits boaters who keep basic service supplies on board or in the workshop and want a dedicated pump matched to standard gear lube bottles.
