ok so I was wiring my boat for electrical downriggers, taking the plunge from manuals finally, all went well then I put a second battery in the rear battery compartment. Then I noticed under the new battery a slight puncture thru the floor, about the size of a quarter. If I push down there is some moisture, this area is grey not the white fiberglas like the main floor is and to me the floor seems thin there. The boat is a campion 185. Not sure if I should worry or how to repair it, for now I put some eternabond waterproof tape on it. Is that enough? Should I worry about the moisture? The boat seems totally solid otherwise. Should I lay marintex over it or horse someone.? How urgent is this? Thanks for your help!
