I try to not mind other peoples business but wonder if I should in this
case. I didn't ask what you wanted to do with the dimensions. The board
isn't a simple rectangle: it is cut out on the bottom to accommodate the
engine "box" so if I were replacing the board I would use the size I
measured. It will not fit as-is and if you wanted to fit an electrical
panel larger than what you have now it may not fit. I'll be glad to
provide more: dimensions and location of the cut-out, a photo, etc. Just
ask. The boat is ~30 feet from my front door.
