Lay down plenty of new sealant (DO NOT use 4200 or 5200) and rebed the cover plate.

As far as sealant goes, I recommend 3M 101.

Also, if you have a leak, it may have compromised the core. If that's the case the job will be more difficult. While the cover plate is off, see if the core is wet or rotten. If it is, you'll need to excavate the core around the chainplate, fill with epoxy thickened with colloidal silica, and rebed as described above.
I understand what you're saying. However, the coverplate on the Caliber 40LRC is attached to the chainplate. So, there is no way to lift up the coverplate. On my previous boat, the coverplate could be lifted off of the deck, and the sealant could easily be replaced. Not so on this boat. You can visit this website to see an illustration: Caliber Multi-Bulkhead Bonding System(tm) click on "Double-Lock Chainplate System" to view. It seems as though I may have to loosen the shroud, remove all the bolts attaching the chainplate to the bulkhead, and then try to remove the chainplate and rebed it in sealant.
