A buddy has a late 80's 85 hp force engine. Its a 20 inch shaft. I have a 125 force with 25" shaft. Can i swap the lower units? Put the 25" shaft on the 85 hp motor?

Re: quick lower unit question

From what i understand about the lower units for this motor. If the bolt patterns are the same it should work but you will have to disassemble both units and switch out the shafts. He will probable also have to change to a different prop. I would just suggest finding a lower unit of the same year and shaft length.
