Seepage around keel bolts
i am looking for some ideas regarding our newly aquired sailboat. I have noticed water seepage near the aft pair of keel bolts. When the boat was purchased, she was on the hard and the bilge was spotless, all painted nice and white. After a month in the water, around July, i noticed the iron oxide forming on the washers of the keel bolts. The washers and nuts appear to have corroded the most from the brackish waters of the chesapeake. There was some sealant under the washers and the bolts look clean. All of the sealant / caulking was removed and was used to fill in a small void aft of the bolts. The bolts appear to be installed through a wooden block, because in removing the caulking, wood fibers were identified adhered to the caulk. is this cause for alarm and should the keel be dropped and bolts replaced?
The boat was pulled recently and she has flush / countersunk thru hull fittings, of which two are suspected to be leaking and in need of rebedding. One thru-hull is used for the flush water in the head and the other is used as a drain for the galley sink. The brass ball valves attached to the thru-hulls are very green, and one of the thru-hulls is less than 12-inchs from the water seep in the bilge.
i am suspecting the thru-hulls as the source of the small seep next to the keel bolts, however, i do not detect any holidays / delam in the fiberglass. Is it posible for the thru-hull to leak and "drain" into the bilge area without causing any delaminations in the fiberglass?
My plan is to rebed the thru-hulls and was wondering on what sealant to rebed.
Thanks for the help!
