I think that some models of 500EFIs had them. I know for a fact that my 00' models DO NOT have a combo, electric only.

Would you expect the same model of engine to utilize the same parts......not from Mercury!! 
That would make too much sense. 
I saw his pumps also and wondered what they were in there for..........

without the mechanical pump they have vapor lock issues and the electric is needed to provide enough pressure for EFI system. Also electric fuel pumps push much better then they pull where as mechanical diaghram pumps pull and prime better.
