The Johnson Pump 09-812BT-1 is an F6 impeller kit made from MC97 material, with 12 blades and a spline drive. The outside diameter is 2.25 inches and the width is 1.90 inches. It is meant for compatible marine raw water pumps, with Volvo Penta given as the application. Its job is to keep cooling water moving through the engine cooling system, so the blade count, size and drive all have to match the pump it goes into.
Our take
Twelve blades on a 2.25 inch outside diameter with a 1.90 inch width and a spline drive: those figures define which pump housing this impeller belongs in, and Volvo Penta is the application named.
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.
