We are in the process of replacing the fixed ports on our 1983 Hunter 31. We got the first one out and I have learned a few things I want to share and want to get some guidance. First, on some archived posts about replacing fixed ports on older Hunter 31's there was some indication that you can't just simply replace with a new Lexan piece cut to size. I called Mark with Mark Plastics in Ca. some previous posts recommended him. He asked me if my frame was plastic or aluminum. They are aluminum, he indicated those windows predate his involvement. He did say that he could sell me a new fixed port frame and all that would be plastic and fit. But the aluminum frames are good, plus I would always prefer aluminum over plastic.
Upon getting it completely apart what I found was that the whole thing sets in from the outside. the inside trim is only cosmetic. We can cut a new piece of Lexan bed it in then place the whole frame and glass in from the outside. See Pictures.
So my questions are two.
One. Acrylic vs Lexan? Lexan is more expensive with fewer color options. Acrylic has more color options and UV protection (for the inside).
Two: Bed it into the frame with Boat Life Caulk or Butyl Tape? I would use the Life caulk to bed it in then come back and caulk it in around the frame. For sure I will use Butyl tape when putting the frame in against the boat exterior and screws. The life caulk seems like it would be easier to get into the gap between the glass and the inside of the frame. See the last picture, with existing glass in silicone scraped out, the gap to fill between glass and frame is pretty significant. Your experience would be appreciated.
