Greetings all,
I had noticed this before and on checking it out again recently I've decided to remove and replace the mount for my bow thruster battery. As you can see from the image, there was some previous leakage and battery acid damage to the laminated plywood (marine plywood??) shelf, at each of the four battery box screw holes, predominantly in the port, aft area (the image is looking forward). One of the plastic battery strap 'hold-downs' has also failed. Easy removal of the board, and it is not too big - 9.5" x 35.5" x 1" thick.
I'm writing to ask for recommendations for replacement board/material for this shelf. I'm leaning towards StarBoard (likely same thickness to get the rigidity needed) rather than a marine plywood or solid hardwood but would love anyone's experience and thoughts on this. And if wood, how did you prep the wood for use - varnish? polyurethane? etc.
Thanks in advance!
Brian.
