Attwood Gear Lube Pump

The Attwood Gear Lube Pump is a purpose-built maintenance tool designed for boaters and anglers who understand that proper gearcase lubrication is non-negotiable for long-term engine reliability. Whether you're running a saltwater charter, maintaining a bass boat, or keeping a cruiser ready for weekend expeditions, this pump eliminates the mess and guesswork of manual gear lube application. It's engineered specifically to work with 32-ounce gear lube bottles, the standard size used across the majority of outboard and sterndrive engines.

This universal-fit pump design accommodates nearly any outboard or sterndrive configuration, making it invaluable for multi-engine operations or those with older equipment lacking modern quick-fill systems. The included Yamaha adapter ensures compatibility with Yamaha powerheads while the universal housing works across Mercury, Honda, Suzuki, and other leading marine manufacturers. At just 1 pound, it's compact enough to stow in your engine compartment or tackle locker, yet robust enough to handle the viscosity demands of modern synthetic and conventional gear lubes without clogging or stalling mid-application.

Service intervals become faster and more thorough when you eliminate hand-pumping fatigue and bottle spillage. Serious anglers and commercial operators benefit most from this pump's consistency—every fill delivers the correct volume without air gaps or overflow. Installation takes seconds; simply attach the appropriate adapter, insert into your gearcase vent, and dispense. For anyone serious about preserving their investment in marine engines, the Attwood Gear Lube Pump is standard maintenance equipment that pays dividends in reliability and resale value.
