I think what you need, to pump water are a gasket and impeller. The gasket should be 324901. The impeller, I suspect is the same as a 9.9/15, which is 386084. If you need a cup, that’s a little more speculative but it is probably also a 9.9/15, which is 324091. Pics below, I hope….First is the 6 hp impeller next to the 9.9/15 impeller. Same outside dimensions. Second picture is of the 9.9/15 impeller in the same housing the OP has. The 9.9/15 has a half inch shaft. My bet is that it is the same as this Worktwin.
Long live American manufacturing!
