🔌 Function

Threads into the impeller hub and is tightened against the pump face to draw the impeller off its shaft under controlled load. It is the clean way to get an impeller out of a seawater pump, with none of the risk of damaging the pump housing that levering brings.

⚠️ Common Signs of Failure

• Thread on the screw stripped or galled
• Screw bent or the drive on the head rounded off
• Screw seized in the component it was left in
• Tip mushroomed or peened over from use

🛠️ Service Notes

• Order the screw against the impeller number rather than the engine, since the three sizes are matched to three different impellers
• Grease the thread and work the screw evenly, because snatching load onto a puller screw is what bends them
• Always refer to the operator's manual for the recommended maintenance and service intervals for your engine and drive
