This is a Johnson Pump flexible impeller kit for the F4 pump, made of polyurethane with six blades. It measures 2" across and 0.87" wide and fits a 0.31" flatted shaft. Johnson gives it as a replacement for Jabsco 6303-0007, and describes its impellers as built for maximum flow and long life.
Our take
Johnson gives this F4 impeller as a replacement for Jabsco 6303-0007, so the 2" x 0.87" six-blade size is what to match against your pump. The 0.31" flatted shaft is a second dimension to confirm.
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.
