Parts Desk Insights
This is the pump to have if you're doing your own lower unit gear oil changes — trying to fill a lower unit without a proper pump is messy and imprecise. The pump threads onto standard gear lube bottles and the included adapters fit the fill port on most outboard lower units. If you're starting from scratch and need both the pump and gear lube together, the Hi-Performance Gear Lube & Pump Kit bundles everything in one box at a better value. This standalone pump is the right buy if you already have gear lube on hand or prefer to choose your lube separately. The aluminum fittings hold up significantly better than plastic alternatives over repeated use.
