    This is the Honda impeller that will work if you shim the bore:

    Honda 19210-ZW9-013 19210-ZW9-003

    Best way to do it is to enlarge the bore a bit with a dowel and some sandpaper, the superglue in a small length of this tubing:

    K&S #140 17/32 round brass tubing

    Then file a groove for the drive pin.
