I have a 1982 Hunter 22. Love the boat, which I've had for 4 years, but hate the constant worry about a leak I can't find. I know the swing-keel Hunters are notorious for leaks around the through-hull bolts holding the keel pivot brackets. I've reworked this area every year when I pull it out of the water. Remove the old 5200 calking and put copious amounts of new calking under, and around the brackets. I also fill the bolt holes before inserting the bolts.I just can't believe I'm still getting water in the bilge from around those bolts. I've tried reversing the process when I have the boat pulled out of the water. Filling the bilge with water and looking for leaks underneath. However, I realize the water in the bilge is not under pressure and does not perform the same way as water being forced up from the bottom while she is sitting at dock.What else can I check and how do I go about it? Anyone have any secrets for locating leaks... I'd love to hear them.
