Yesterday I was mounting the transducer to the lower transom exterior. I made a couple of small drill incisions, and when i did I had some water seep out. Just a couple of drops, but it came as soon as i was through the outer layer of gelcoat/fiberglass. I am completely baffled as to how it could have gotten there. Obviously this is of concern to me. I would love any suggestions with how to proceed. Thanks, Ian
