Parts Desk Insights
The 850730Q1 is the right tool for anyone doing their own gear lube changes on a Mercury outboard or MerCruiser sterndrive. Trying to fill a gear case by pouring from a jug is messy and slow — this pump makes the job clean and straightforward. It’s particularly useful at winterizing time when you’re changing gear lube across multiple drives. The kit works with all grades of Quicksilver gear lube, including the Quicksilver High Performance Gear Lube (5 Gallon) and the Quicksilver High Performance Gear Lube (858058KC1). If you want gear lube and a pump together in one purchase, see the Quicksilver SAE-90 Gear Lube & Pump Kit (8M0222069). Note: Japanese-built Mercury and Mariner outboards require the metric adapter 883704Q03, sold separately.
