Additional Information

Why Use the Correct Impeller Puller:

Impellers that have been in service for a season or more often bond to the pump housing — heat, compression, and rubber aging all contribute to a tight fit that resists removal. Attempting to extract a bonded impeller with screwdrivers or improvised tools risks:

• Gouging or scoring the pump housing bore
• Tearing impeller vanes, leaving rubber fragments inside the cooling system
• Damaging the pump body in ways that require full pump replacement
• Extended labor time on what should be a straightforward service task

The Johnson Pump 09-47154-01 puller is designed to engage the impeller correctly and apply even extraction force — protecting the housing and getting the impeller out intact so you can inspect it properly before installing the replacement.

When You Need This Tool:

• Annual impeller replacement service on 1027BT or 812BT pumps
• Seasonal layup inspection and impeller removal
• Any time the impeller needs to come out for inspection after overheating or restricted flow
• Service shops performing routine pump maintenance on vessels equipped with Johnson Pump 1027BT or 812BT

Frequently Asked Questions

1. Which pump models does this puller fit?
The Johnson Pump 09-47154-01 impeller puller is designed specifically for the Johnson Pump 1027BT and 812BT models. It is not a universal impeller puller — confirm your pump model before ordering to ensure correct fit.

2. How often should the impeller be replaced on a Johnson Pump 1027BT or 812BT?
Johnson Pump generally recommends impeller inspection annually and replacement every 1–2 years or any time the pump shows signs of reduced flow, overheating, or impeller wear. Always replace the impeller if vanes show cracking, deformation, or permanent set — a failed impeller can leave rubber fragments in the cooling system that cause downstream damage.

3. Can I remove the impeller without this tool?
Technically yes, but it significantly increases the risk of housing damage and torn impeller vanes. On pumps where the impeller has bonded to the housing after extended service, improvised removal methods frequently result in damage that requires pump replacement. The correct puller pays for itself the first time it prevents a housing replacement.

4. Do I need any other tools for a complete impeller service?
For a complete impeller replacement on a 1027BT or 812BT, you'll also need the replacement impeller and any applicable gaskets or seals for your pump model. Contact us at MacombMarineParts.com with your pump model and we can help confirm the correct impeller and service kit parts.
