    Yamaha 50 block Swap?

    Hey gents, tried searching through forums and I can't find a similar thread. Are the blocks on a 89' pro 50 and a 99 swappable? Minor rear end collision made my mid and lower inoperable, found a pro 50 at a decent price and would like to drop my built head on it if possible. Thanks for any help and time!

    I think he's asking if the powerhead will swap mids and lower splines.
