I have the same issue with our 1982 N28. The portlights leak around the glass. Yes, our portlights are tempered glass in an aluminum frame. I have contacted select plastics, and his recommendation was to remove the entire portlight from the boat. cut out as much of the external portion of the rubber seal, and inject a bead of DOW 795, and carefully tool to shape. It does not look like it is going to be any fun doing that job. Fortunately, the inner ring on ours comes off easily after the screws are removed. I'm sure the frame to cabin wall seal will be a whole lot more difficult to get separated. Its getting to be winter time, so that job will have to wait until next spring/summer. I will do again what I did last winter to keep the water out. I tape a piece of plastic sheeting over the entire port assemblies on both sides. I use the clear Gorilla tape to attach it to the fiberglass above and down both sides of the ports. I leave the bottom of the plastic open so it can breath any moisture that may get into it. Not the prettiest look, but it does keep the weather out. After the spring rains, peel the tape/plastic off, and clean of the tape residue with acetone or mineral spirits.
jsailem,
Your replacement ports look great. are yours the aluminum frame with tempered glass? Sis you replace them yourself, or did you have a shop do it?
The attached pictures show the ports that are in our 1982 N28. I would really like to find the proper glass to frame seal for ours.
