Installation Notes

  1. Ensure the engine is off, cool, and the battery is disconnected.
  2. Close the raw water intake seacock to prevent water from entering the vessel.
  3. Remove the water pump cover plate to access the impeller.
  4. Carefully thread the impeller puller tool clockwise into the threaded center of the impeller until it is snug.
  5. Hold the outer body of the puller and tighten the central bolt clockwise. This will push against the pump shaft and gently pull the impeller straight out of the housing.
  6. Once the impeller is removed, clean and inspect the pump housing for scoring or debris before installing the new impeller.

Troubleshooting & FAQ

How do I know if this puller fits my impeller?

This tool is designed for Sherwood impellers with a 3/4"-16 internal thread. It is compatible with the 17000K, 18000K, 22000K, 26000K, 29000K, and 30000K series. Always verify your impeller has these threads before purchase, as not all impellers are designed for puller removal.

The puller isn't threading in. What's wrong?

First, confirm your impeller is the correct type that requires a threaded puller. Second, check the threads on both the tool and within the impeller for any damage, corrosion, or debris. The thread size is 3/4"-16. Do not force the tool, as this can damage the impeller or pump shaft.

Is this the same as the Sherwood 25105 tool?

Yes, this is a direct aftermarket replacement for the Sherwood 25105 puller tool and its older version, 23631. It performs the same function and is built to a comparable standard of quality and material.

What happens if I don't use a puller on a threaded impeller?

Attempting to remove a threaded impeller without the correct puller can damage the impeller, pump shaft, or the pump housing itself. Using screwdrivers or pliers for leverage often results in bent shafts or cracked pump bodies, leading to more costly repairs.
