Power Head swap

New here and like to start off by saying Hi.
Heres my dilemma, i've got two 25 hp rudes, one is a mid eighties, model # is long worn off, it has a split lower unit and the kill switch is in the handle not on the front. number on the expansion plug is G2624440.
The second is a mid nineties no model # anywhere, # on the expansion plug in the block is G3265397. Can I swap power heads? The 90's had a seized piston and the 80's had a bad lower unit. ANY info would be great. Thanks.

Sorry about the double post. Well I found out that the answer yes, but you need to swap out the whole head. Which I going to do anyway.

anyone know which power heads will fit on a 1979 johnson seahorse 55hp?
sure would be nice to have ten years to play with like charger25...

go to home page and look at the parts schematic for your number and write down the # for ur crank and cylinder ass. Then go forward year by year and find a match...

I take it there's 6 bolts( 4 bolts n 2 studs) that hold the head on, got 'em all out and head still won't come off. Don't want to beat on it too much so whats the secret?
