The older M17's and newer ones do not have the same port windows. The older ones used two piece aluminum frames. One piece had a channel that held the glass in place with a piece of rubber channel gasket. If memory serves, those frames were made from several pieces, which were either riveted or soldered together. It went on the outside. Inside was the second piece, which screwed to the outside piece. The cabin itself is flush, with a port window sized cutout. The newer boats do away with the frame and simply screw the plexiglass to the side of the cabin, but inset into an indention that is formed into the cabin. I ran into all kinds of trouble replacing my side lights, as I could not find the rubber channel gasket. So I did a "modern" replacement: http://audasea.montgomeryowners.com/?p=20 In retrospect, you might also go with a thicker plexi or lexan to fill the gap in the metal frames and use silicone or bed them using the same black sealant glazing compound the car guys use with windshields.

SWEET PEA spent most of her 'before me' life on-buoy 1/2 the year. the usual orientation in her anchorage was port side facing the afternoon and evening sun. the starboard faced a tree-covered shore.

Neil....
Why Lexan..?..Lexan cannot be tinted and it scratches easily.
We use ACRYLIC smoke tinted windows on the production M Boats and they are 1/4 inch thick.
Why spend the money $ on a Router Bit and a half sheet of Lexan or Acrylic when you can buy new windows already to install for $20 each from us...?
They come cut out and all you would have to do is have someone hold them in place while you back drill the new holes. We use Marine Silicon (no mold issues).

Jerry,
Thanks for the reply. Hope yourTucson trip was enjoyable. Can the Lexan cutting be done with a dremmel tool and the appropriate disc?

They are undercut at 45 degrees, which we did on a router. If you have and are familiar with routers, get a carbide 45 degree bit and carefully make a pattern off the old one. I don't think you could cut one with a bandsaw; it would chip and fuzz up too much.. Have fun!

I would like to redo my M15 port lights with new Lexan and was thinking I could use the existing ones as a template for the new ones. But I can't tell for sure until I remove them if they would actually lay flat or are slightly concave.
It looks like what's entailed is removing all the screws and I suppose there is some silicone caulking / adhesive sealant underneath...
Anyone know, or attempted this?
thanks, Neil
