Be sure to add a piece of wood on the inside big enough for the control box to screw into.
Make certain the back 18 inches of the bottom are perfect or boat will hobby- horse.
The transom bracing is not sufficient, so leave the screws in the bottom and in the transom: Use lots of filler in the transom angle and add 1 3/4 inch aluminum vertical supports in the verticle angle.
Don’t carry the motor on trips attached to the transom.
