This is a Johnson Pump flexible impeller kit for the F2 pump, 1.29" in diameter and 0.50" wide, with six blades. This one is nitrile, the oil-resistant compound, rather than the MC97 or neoprene types used for cooling duty. The maker describes its impellers as built for maximum flow and long life. A worn or damaged impeller can lead to system failure or an engine breakdown, so it is a part worth keeping an eye on.
Our take
Nitrile makes this F2 impeller the oil-resistant choice, set against the MC97 and neoprene types the maker lists for cooling. Check that your pump is an F2 taking a 1.29" x 0.50" impeller before fitting it.
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.
