There's plenty of room back there so if you're prepared to drill the mounting plate, I guess almost anything could be made to fit.
A 2hp in a non-standard shaft size (should be 24mm x 50mm if its a 90 frame).

Looks like I'll have to take this one off and measure it properly, then put it back so i can use it to make the mounting for the new one... then take it off again...
