[C320-list] Leak in bilge

[Kurt Budelmann]

Hey, I am having a slow leak in the bilge right by the bilge pump.  No collections of water fore or aft of this location.  Can water leak down from top of mast?  Can water leak from the keel bolts?  Also there is a floor joist crossing at that location but I can find no evidence of leaks from ports.  I don't think keel bolts were ever re- tightened and the boat has never been out of the water since original launch.  Can the bolts be tightened in the water or does the boat have to be on the hard?
