OMC and Johnson powerhead question

I had just purchased a A new boat to me that came with two 1989 OMC 120 Sea Drives One running one completely dismantled my father passed away and left me his brand new Johnson 140 horse 1995 if I remember correctly my question is can I take the powerhead off of the Johnson and put it on the OMC
Here are pictures of both powerheads the first two are the OMC
Three and four are the Johnson
Please any help would be very much appreciated

That was always the problem with those sea drives once you got one you were stuck with it. One question I have, why do you call a 1995 outboard a "brand new one".? I'm sure somebody here will be able to tell you if that'll cross but not me.

They are both Loopers. However they are different HP so, that makes pairing them up iffy. A lot of Parts in/on the powerhead could be different. That includes the Block, Carbs, Induction System, Exhaust Tuning, to name a few. A very thorough look at the Parts Lists of both will need to be done

My father bought the motor brand-new and less than six months later my mother got cancer and he never got on the boat again the motor has sat in our garage for 22 years it only has 33 hours on it

From what I can tell both mid sections use the exact same bass gasket from my research the only difference in those two motors is bad the carburetors are different that is it

Oh shoot, sorry to hear that. Life throws curve balls and when stuff like that happens it effects everyone. My advice, get another boat (without or a blown motor) put that 140 on it and whenever you go full tilt remember and salut your Dad or modify the other boat to accept the old engine. With all those parts you got with the boat is enough to make it run?
Kind of a tough one, hope you figure it somehow.
