The WR014H driveshaft holding tool fits onto the end of the Yamaha driveshaft within the pump of the 155mm pumps with the 25mm driveshaft. This size shaft is commonly used on the Yamaha SHO, FZR, FZS and similar models made.

We use this tool to hold the shaft while tightening/loosening the impeller from the shaft. We also suggest buying the WR014 impeller tool for Solas impellers to remove/install the impeller to/from the shaft.
