I want to remove the windows in my '77 Trillium 1300, seal using butyl tape and re-install. The galley window was easy - remove outside screws and it comes right out - there is no metal frame on the inside, so nothing to stop it.
Not the case with all the other windows. There is an aluminum frame on the inside that appears to overlap the inside wall (ensolite?). The whole window frame appears to be one piece, no visible screws. After unsticking it from the fiberglass body, I pulled at it, twsited it, etc. but no go. How do you get it out?
the windows went in so they will come out. First, make sure ALL of the screws are out (including the ones hloding hte curtain rod brackets on and any other hardware especially the overhead storage. the ensolite is tucked under the aluminum frame. Use a tool (scredriver/etc.) to pull the little bit out to allow the window.
If this does not give you a little room use the screwdriver or small prybar to push the wood away from the window frame
If you did this then the only thing that is holding the window in is the old grey mastic which will come apart with a flexible putty knife.

window replacement on youtube for more details. I have all of mine out except for the galley window. Only because it is actually riveted in.
PS. if you already have the caulking loose underneath. MAKE SURE that you have someone on the other side before you pry on the wood/window frame or it WILL pop out on you when you don't want it to. And they are not easy to replaace if damaged.
It sounds like I am only about 2 days ahead of you in the restorations.
