I have the same port lights, if I'm understanding your description correctly, on my 1968 Pearson. I re-bedded two of them that were leaking, using butyl tape, after reading all of Maine Sail's excellent tutorials. The previous owner had bedded them in BoatLife stinky caulk. What a stink that made, scraping all that crud off!
Anyhow, it worked extremely well. Nary a drop since.

"Twenty years from now you will be more disappointed by the things you didn't do, than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover."
