Impeller-Free Gear Pump for Clean, Reliable Oil Changes
The GP8-19 is a compact, battery-powered gear pump designed specifically for oil changes on marine engines. Unlike impeller-based pumps, it has no impellers to burn out or replace — the PTFE pump body and gears are built for long-term durability and resist degradation from oil and fuel contact. The pump is self-priming up to 3.2 ft., so it draws fluid without manual priming or suction assistance.
Everything needed for a clean oil change is included in the kit: dipstick extraction tubes in two sizes fit most engine dipstick tubes, and the 70″ power cable with battery clamps connects directly to your boat’s 12V battery.

Parts Desk Insights
Best Use Case: The GP8-19 is the right choice for boaters who want a dedicated, reusable gear pump for engine oil extraction — particularly those with inboard or stern-drive engines where dipstick-tube access is the only practical way to remove oil. The PTFE construction makes it suitable for repeated use with hot oil without degradation. For a complete kit that includes a collection pail, see the Johnson Pump 65000 12V Complete Oil Change Kit with Pail. For a 24V electric option, see the Jabsco 24V Electric Oil Change Pump. For manual extraction without battery power, consider the Panther Pro Series Manual Fluid Extractor or the Panther Pro Series Heavy Duty Manual Fluid Extractor.
