I have been going over my boat and getting her ready to go this Spring and noticed the lowest plate to transom bolt on the passenger side is lose and has a water mark . It appears to have been weeping .I had plans to remove the bolt, fill the hole w silicone and reinstall the bolt. This is tough to do by myself and will have a friend help me tomorrow night ,however, how concerned should I be about the weeping?, does this mean I have a bigger issue? Thanks in advance
