I do not see the need. I have an enclosed transom on a 1984 23' CC, has a bracket with a 225 2stroke and is rock solid. If you plan on adding more weight to the transom, it could effect the self bailing, especially with a heavier 4stroke, that is unless you are going to raise the floor. The floor in mine is about 2.5/2.75 inches higher that factory. Every little bit of weight here and there adds up. With three guys and a 65gal tank in the rear full mine stills bails pretty good.
