I am trying to figure out where to place my batteries in the boat. I am planning on putting in two of the blue top batteries. Here is a pic of where I want to mount them, the battery box is where I would put it. I would put the other one in the same spot but on the other side of the boat. Does anyone know for sure if I can cut a hole here so that I can countersink them into the floor. I want to do this so they will fit under the seats. I obviously don't want to do this if there is going to be a problem with strength or hull integrity.
