water wicks down the wires of my deck-stepped mast. There is barely room for the wires to come through the deck so caulking from underneath is not possible. I have a couple ideas for TRYING to caulk or fill the bottom few inches with foam. But both necessitate drilling a hole in the mast. and then I can''t be sure of causing the water to run out the bottom of the mast or making a big mess. This is the only thing that is keeping my cabin bilge dry! Anyone got any suggestions.
