Heurofosh Sherwood Impeller Puller 3/4"-16mm Threaded Tool — Precise OEM Fit for Marine Water Pumps

The Heurofosh SH 25105 Sherwood impeller puller is a dedicated 3/4"-16mm threaded tool designed to safely and quickly extract Sherwood impellers from marine water pump hubs.

When routine engine maintenance or impeller replacement is due, having the correct puller dramatically reduces time, prevents damage to the pump housing, and simplifies the job for boat owners and mechanics. This tool precisely matches Sherwood impeller hubs and threads into the impeller so you can pull the part straight out without prying or risking deformation.

How does the SH 25105 make impeller removal easier?

The puller screws directly into the impeller hub using the 3/4"-16mm threads, creating a central anchor point to extract the rubber rotor. Instead of working from the outside with improvised tools, this unit provides even, controlled force to remove the impeller.

• 3/4"-16mm threading matches Sherwood impeller hubs precisely
• Central threaded pull prevents off-center pulling and warping
• Saves time compared with improvised extraction methods
• Reduces risk of damaging pump housing or impeller bore

Which Sherwood impeller kits and models is this compatible with?

The puller is engineered to work with a range of Sherwood impeller kits commonly used in marine cooling systems. It fits Sherwood-model impellers that accept 3/4"-16mm threading so you can service multiple kit sizes with the same tool.

• Compatible with Sherwood kits: 17000K, 18000K, 22000K
• Also fits: 26000K, 29000K, 30000K impeller kits
• Designed to thread into original Sherwood impeller hubs

What are the practical benefits of using this manufacturer-specified tool?

Using the proper Sherwood impeller tool reduces repair time and prevents costly mistakes. The tool’s exact threading and fit mean fewer stripped threads, less corrosion-related difficulty, and a cleaner maintenance experience overall.

• Minimizes risk of thread damage or housing gouges
• Speeds up part replacement during routine service
• Compatible with OEM Sherwood parts for reliability
• Compact, easy-to-store tool for on-board toolkits
