New transom cracking in splash well

[Entourage]

He has to put a new piece of 3/4 going from side to side in side the splash well where the top bolts of the motor are. Also he is also going to put 2 braces going from front to back inside the splash well. Sounds kind of strange but he says it is the right thing to do. The cracks went from where the factory aluminum transom trim molding where placed side to side. I will post pics when i get it back.
