This is a Johnson Pump replacement impeller kit, part 09-702B-1, made of the maker's MC97 rubber. The material is described as durable, as keeping pressure steady over time, and as limiting both fatigue failure and swelling of the impeller. Johnson Pump says its original impellers are engineered for more than 2,000 hours. The kit is listed for use with a long run of engine and pump brands.
Our take
MC97 rubber is the selling point here: Johnson Pump says it keeps pressure stable over time and limits swelling and fatigue failure. The 2,000 hour engineering figure is the maker's own claim, so treat it as a design target and not a service interval.
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.
