This is a Johnson Pump nitrile impeller kit for the F4 pump, part 09-810B-9. It has 6 blades, measures 2.00 in across and 0.87 in wide, and fits a 0.47 in shaft. Nitrile is the oil-resistant material in this range, while the cooling impellers are made from MC97/EPDM and Neoprene. The 0.47 in shaft sets it apart from the 0.50 in version of the same F4 kit.
Our take
The 0.47 in shaft is what separates this F4 kit from the 0.50 in one, so measuring the old shaft matters. The nitrile compound is the oil-resistant choice in the range, with 6 blades on a 2.00 in by 0.87 in body.
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.
