I have a 1985 Hunter40.there is a shelf in the bilge about 8-10" above the area where my float switch is located.At the back end of the shelf is a fiberglass vertical bulkhead (?) with a 1 1/2" diameter opening.Water ever so gently rolls out of that hole onto the shelf. I can put my finger in and it feels like about an inch of water.Not Bay water either.I can't seem to find any leaking anywhere that would account for this standing water. Anybody have any ideas????? I am stumped as to why it is there and where it may have come from. Thanks,Alan
