If the exterior frames are in good condition (no kinks, minimal corrosion), it’s definitely worth doing. Pull out the grey gasket and the lens just comes out. Drill out the rivets, undo the bolts, remove the frames and clean them up. You can throw out the interior rings if you decide to fill the gap. Since the space in yours is greater than mine was, you might consider epoxying splines of appropriate thickness in the gap all around. This will give the consistent thickness you want and straight edges as well. Sail batten material stacked to be thick enough might be the answer. Clamp them in place so you don’t lose them! Use the original lenses as patterns for the new ones. Lexan isn’t great in UV, so they sell it with one side treated. Make sure that you install it with that side out! You’ll need to obtain new gasket material. I remember a post a few months ago where someone had a source for gasket other than buying some of the original stuff.
Before reinstalling the frames, you have the opportunity to make the holes really nice and neat and paint the areas. When I reinstalled my frames, I decided that using screws only along with sealant was strong enough to suit my taste, so I have nothing showing on the inside of the boat. You could through-bolt the corners and maybe the center holes if you aren’t sure. It’s a very satisfying and not-too-difficult job if you commit. Have fun! Rich Klajnscek, P.Eng.
