Bob-
Yes, the screw holes may be the same, but it is all in the orientation of the pump housing. Most of the little OMC pumps have a raised indicator saying "up", this indicator must be facing upward in order for the pump to work right. The fuel pump mounting holes are oriented differently on different engines. So, I am thinking that the orientation of the inner workings is different on the two pumps you are looking at.
