Hi Giovanni.  On SM 243 the portlights were sealed with a LOT of clear silicone caulk.  That made removing the wooden panels inside very difficult.  If you use anything stronger than that you will never get the panels off without destroying them.

Duane,

I second Craig's suggestion.  Plus, if it fails in less than 50 years Craig will come and personally fix it for you. ;)

3M 5200 is known as "The Devil's Glue" and should really only be used on things that you never, ever, want to take apart again.  Offhand, I can't think of a single place on my SM that I would use it in place of something that is almost as strong but way more removable like 3M 4200. 

Here's a pretty good article on marine adhesives from Practical Sailor:  https://www.practical-sailor.com/issues/36_8/features/Marine-Adhesives-Caulks_5953-1.html
