I'll probably be on most of the trips with Jason. He has probably considered this in his lay out and will be placing me in "shotgun" to ensure weight forward in seas.
On a more serious note, there is allot to be said for BIG trim tabs. Both J and I have large tabs on our boats to deal with the prevalent gulf head seas. There is no such thing as trim tabs that are to big. If they are not down and correcting trim issues, they are up and providing extra planing surface.
I really think that J has circumvented stern weight issues by not opting for a bracket. These boats where originally designed for transom mounted engines and I really feel there will be weight distribution benefits due to his choice.
I own a 23 vintage express style boat that has been equipped with a single 250 /Suzie on a long bracket. Sometimes I wonder if the benefits of a full transom and a little extra speed are worth having my boat’s center of gravity moved so far back. It really is evident when I have to use so much tab to shove my bow down in seas. If Jason’s transom works out as well as I think it will, I could see myself having a bracket for sale next year.
