Josh,

Pull your chainplates and check that the area around them in the deck has been epoxy sealed (e.g. no way for water to get to the core). Once that has been done, you can reinstall them. Use a good expandable caulk to fill the void between the plates and the deck with polyvinylsulfide or butyl caulk such as Boatlife, Sikaflex, etc. (not adhesive like 4200).
