I am looking for some info to help with a project of mine. I need to know if the shaft on a xl1200 will fit in a waveraider 1100 coupler/midshaft, like is that shaft diameter the same and are the splines the same I can't seem to find any info on it. I am building a boat and want to adapt a xl1200 pump to a waveraider 1100 motor. Just seeing what my options are. I have the 1100 waveraider coupler and bearing housing installed and am looking for info before I purchase a pump and shaft assembly. Any info would be greatly apreciated
