Are you thinking of running the bolts from the motor all the way through the bracket then into the transom with one continous rod? If so you may want to make up a sleeve for the inside part so it does not "squish" the whole bracket. Or maybe just nuts and washers on the inside between the transom and bracket and the motor and the bracket. Just a thought.
Nice work so far. Can't wait to see it in the water.
