All the hinges are broken on the port lights in my 1982, 31', Open. I have part #5390050 and 6223 VASSEN OPENING PORT as information so far, but still can't locate replacements. Any clues would be greatly appreciated.
Part # 5390050 6223 VASSEN OPENING PORT W/SCREWS.
Made by Vassen, unfortunately they are out of business.
You may need to replace them with a portlight that is available today.
I started a thread for my '85 3100 with broken port hinges too. I own a wholesale/retail marine supply store so I have access to a crazy amount of catalogs to source. Lewmar has some that could be modified to work, but in the end, I took the old ones to my local machinist and had him dup them in aluminum.
