Hey everyone, I have a great running 73 merc 650 with no tnt and a 74 merc 650 that runs rough with a good tnt. My question for anyone who has more experience workin on these thing than me is this; would it be easier to try and swap the mounting brackets on the motors so the better runner has the tnt or would it be easier to remove the power heads and lower units and just swap onto the tnt assembly?? Any help appreciated, and thanks in advance.

p.s. I am very mechanically inclined, but just looking for a little advice before I start wrenching.
