So I clawed out a fair amount of the foam via the rod box. Except for maybe a 1/4 cup of wet foam (by an inside crack under the damaged strake) it was dry. I cut a hole under the helm pedestal and it was dry too. Can't think of any other phantom weights so I'm gonna try moving the batteries forward as was the original plan. The cable run is 14' for three conductors (the selector switch will stay by the transom). Gonna use 1/0.
I'm torn on battery trays vs boxes. There's not going to be much activity in their new home so terminal covers should be fine for shorts/sparks. The Internet says that boxes are good if a battery cracks and spills acid. Realistically how often does that happen? This is two group 24 batteries mounted amidship with a 57 year old pilot - this isn't the x-games. Not sure I want to deal with the PIA of boxes for something that is unlikely to happen. Thoughts?
BTW, thanks for the tip on the rod holder caps D. - Home Depot is just down the block..
The batteries new home - approximately where the ammo boxes are...
