Even if the power head bolts down you still will have other issues to resolve. Since the metal cowls of that era attached to the power head those changed a lot and even some between E and J. If you decide to try it be sure to document with pictures. You can be the NEW expert on the subject.
As an example I just swapped a ’69 25 hp power head onto a ’60 18 hp. Both have fiberglass tops and free standing belly pans. Should be a piece of cake. Except the exhaust section of the 25 is much different plus it was the newer design that didn’t need the baffle under the powerhead. At least I got to closely inspect all my rubber mounts. And now I have the World’s Fastest Evinrude 18 hp.
