The Jabsco 6303-0007-P is a six-blade urethane impeller kit that includes an O-ring and lubrication. The green polyurethane impeller is 2 inches in diameter and 7/8 inch deep. It fits a 5/16-inch shaft and uses a single flat D drive. Measure your existing impeller against those figures before ordering. The impeller is compatible with some wakeboard and ski boat ballast pumps, including the Jabsco 18220 Series and the Johnson Ultra Ballast pump.

Our take

This suits owners of a Jabsco 18220 Series or Johnson Ultra Ballast pump, or another wakeboard or ski boat ballast pump that this kit is compatible with. If your pump is not one of those, look for a different kit. The main limit is compatibility: the kit works with some ballast pumps, not all of them, so check your pump model first.

From our buying guide

The impeller depends on the pump, so find it by the pump's model number. Makers' schedules differ, with some saying every year and others every 300 hours or three years, so go by the one for your engine.

Check before you buy:

  • It matches your old one on blade count, shaft diameter, outside diameter, material, drive type and depth.
  • You've checked any substitute against the pump housing, since cross-references are the makers' own claims.
  • The material suits the job. Jabsco recommends neoprene for engine cooling, and nitrile for bilge pumping and water with oil or diesel.
