    F90 shaft swap

    You can't bolt a 25" lower unit onto a 20" midsection.-----This requires major work whichever way you look at it.----If you need a 20" motor for your boat than have a shop change out driveshaft and shift rod from 20" lower to the 25" lower.-----Time to look at the parts and think this over..
