    ### Genuine Johnson Impeller F4B

Select the genuine Johnson impeller 09-1026B for the pump application identified below. Its specific size, drive arrangement and blade count help distinguish it from similar marine pump impellers when you are planning a replacement or keeping the correct service part on hand.

Impeller F4B

Check the pump identification and the replacement reference together before ordering. Similar outside dimensions do not establish compatibility on their own; the hub, shaft connection and height also need to match the pump being serviced.

For a physical comparison, check the 50.8 mm outside diameter and 22.0 mm height against the required pump specification. Also inspect the shaft connection; a keyed, pin, flat or spline drive must match the installation rather than simply fitting within the housing.

Follow the pump or engine service instructions for removal, installation and checking the completed work. Assess any separately required seals, gaskets or other service components for that installation before beginning the job. Keep this product code with your maintenance records to make the next like-for-like replacement easier to identify.

### Choosing and using this product

After installation, verify the completed system in accordance with the equipment instructions. The new impeller is one component of the cooling or pumping arrangement; hoses, connections and the pump housing still need to be in suitable condition.

If keeping an impeller aboard as a spare, label it with the compatible pump and part reference. Store it according to the manufacturer’s guidance so it remains easy to identify when needed. A spare is most useful when its fit has been checked before a service is due.

Check the outside diameter, width and shaft or hub arrangement wherever those details are listed. Blade count and drive style can also distinguish parts that appear similar in a photograph. Compare the removed component carefully if its original part number is unavailable.
