Installation Guide
- Ensure the engine is off and the water intake seacock is closed.
- Remove the screws holding the water pump's cover plate and set the plate aside.
- Carefully thread the impeller puller into the internal threads of the exposed impeller until it is snug.
- Hold the outer body of the puller steady with a wrench or by hand.
- Turn the central bolt/handle clockwise. This action will press against the pump shaft, safely drawing the impeller out of the housing.
- Once the impeller is free, remove the puller from the old impeller.
- Clean and inspect the pump housing before installing the new impeller.
Troubleshooting & FAQ
Q: How do I use this tool to remove my impeller?
A: This tool is designed for impellers with internal threads. Simply thread the body of the puller into the impeller, then tighten the center bolt. This will push against the pump shaft and safely extract the impeller from the housing without causing damage.
Q: Will this puller work on any marine impeller?
A: No. This tool is specifically designed with a 3/4"-16 thread to fit certain Sherwood impellers, including the 17000K, 18000K, 22000K, 26000K, 29000K, and 30000K series. Always confirm your impeller has matching threads before ordering.
Q: Why should I use a puller instead of pliers?
A: Using pliers or screwdrivers can damage the impeller, the pump housing, or both, leading to costly repairs. An impeller puller provides even, steady pressure for a safe and clean removal, preserving the integrity of your pump.
