Yes, there are unknowns here. But based on all said I’m thinking that we have a 1969 leg, with a 1979 or later gearcase. (That based on the four screw holes, the shortened spacer/isolator, etc.) Whoever assembled it used a 3 screw metal pump housing that did not really match the gearcase or the spacer. (But I don’t seen any reason it wouldn’t pump if carefully assembled.)
So it is a matter of using the plastic pump that matches that gearcase, not of trying to use a newer pump on an older gearcase.
What are the differences in impeller key? The one that came out was plain round pin, not the type squared on one end.
What am I missing here?
There is an old-line OMC dealer 20 minutes down the road; maybe I’ll go and see if they are up for a consult.
