Hey Guys,
I am a huge fan of the old OMC 18hp motors. I currently have a 1971 Evinrude 18 hp with a bad crank bearing that I'm messing with. I ran across a 1970 Johnson 25hp powerhead that seems to be in good shape, and it is of the same year range. I know these two motors used the same 22 cubic inch block. Do you guys think this 25 hp powerhead will fit onto the 18 hp?
