Hello,Our 1982 Y33 has had her windows replaced a few years ago (before we purchased her). It was done by a local boatyard. The windows are Lexan glued in with 3M5200, no screws. The 3M5200 is starting to look a little worse for exposure to sunlight, and there's a bit of leakage in rain. One of the windows was actually coming away from the coachroof when I pulled at a corner of the window. I temporarilly glued down the corner again with 3m5200. When I did so I could see under the new windows that there are holes in the window recesses in the coachroof sides for screws to hold the windows in. I didn't realise before that the windows originally came fromt eh factory with screws in the windows, but sure enough, when I look at the brochure there are the screws. My question to the forum is can someone describe the screws and washers I should use: Length, type, guage etc. I'm guessing the screws are not recessed into the Lexan because tightening them up could crack the Lexan. I would think the screws and washers are similar to the ones that hold the wood panels in place inside the cabin above the sinks and quarter berth covering the backs of the compasses?Thanks all.TimY33 Miranda II
