This is the Johnson Pump 09-812B-1 impeller, supplied here as a bulk pack of 20. Each impeller has 12 blades and a 2.25 inch outside diameter, which are the figures to check against your pump before you buy. Johnson Pump recommends replacing the impeller every year with a genuine Johnson Pump part so it matches the pump exactly. The old one can be pulled with slip joint pliers or an impeller puller.
Our take
With 12 blades on a 2.25 inch diameter, the 09-812B-1 is a specific fit, so measure your old impeller first. Johnson Pump says to swap it yearly, and a 20 pack means you carry plenty of spares for that routine job.
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.
