I finally got into the gear foot of the Champion HydroDrive. Thanks to jcrigan for the lead on the HydroDrive repair / parts manual. I got the gear foot apart , cleaned up and re-assembled OK. I took several photos of the process that I hope to develop into a tech article for the “Outboarder” as I suspect that this motor is a mystery to others as it was to me. All the internals of the gear/ hydraulics look to be in good usable condition,,, except , of course the rubber water pump impellor. Unlike some of the other contemporary Champions that have metal impellors, this one has a rubber impellor. Now the search begins… I thought that I would start here. The impellor appears to be bonded to it’s tubular steel shaft. no sign of a key or pin. I tried gently pressing that shaft off and there was no movement. here is some info on the impellor … Six vanes 1-5/8 diameter X 5/8 thick, bonded on a 7/16 shaft. Much appreciate any info or leads on this one, Here are a couple of photos.
Thanks,
Joe B
