Will,

Put the keywords "A-22 water pump" in the search block above....Jack Malpass has a description of his experience in removing his impellar, it is in fact 3/8"right hand thread at the impellar end, that was the good news...The bad news is that he broke the shaft off in the impellar in removing it....May want to concider an improvement in that department.

Thank-you for the info.
Dad and I figured that it should be right hand thread but you should never assume
when dealing with something 90 plus years old and rusty.
