This is a Johnson Pump nitrile impeller kit for the F4 pump, part 09-1026B-9. It has 6 blades, measures 2.00 in across and 0.87 in wide, and fits a 0.50 in shaft. Nitrile is the oil-resistant material in this range, while the cooling impellers are made from MC97/EPDM and Neoprene. The maker lists it as a replacement for Jabsco 673-0003, which gives a cross-reference to an existing part.
Our take
The nitrile compound is the oil-resistant choice in this F4 range, while the cooling duty goes to the MC97 and Neoprene versions. With 6 blades on a 2.00 in by 0.87 in body and a 0.50 in shaft, it is a direct match only where the old impeller measures the same.
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.
