I have a total of 6 of the old style aluminum frame windows on my two boat, so I made sure I saved the “recipe” for resealing the portlights for future reference.
Rule 1: never touch the aluminum frame, you will create a leak Between the frame and the window you will need a seal. In 2016 the list recommended the following: Frost King V25BK EPDM weatherstripping M-D Building Products 01025 D Profile Auto and Marine Weatherstripping The MD Building Products stuff is available at Home Depot or Lowes, and a 25 foot long box is pretty cheap – maybe $10. For the window panels I went to a local shop that repairs storm doors and had them use an old window panel as s template to make new windows. I used ¼” cast plexi in a fairly dark color (bronze?) because they had several sheets in stock already and would not need to order a full sheet for a darker color. The window goes on top of the weatherstripping seal, and is held in place by a rubber strip called a spline. Spline material is available at any glass shop that fixes storm doors and/or storm windows. I took a 6” snippet of old spline to a local shop and bought 10 or 12 feet for less than a dollar a foot last time I needed some. I also found it on EBay but would have needed to buy a 100 foot roll. Cheap but who need a 3 lifetime supply of window spline? When installing the seal and the spline, start at the top center of the frame with a smooth square cut end. Go around the frame making sure you get into the corners and making sure you do not stretch the material. I use a tongue depresser/popsickle stick to push the spline into the slot between plexi and frame – pushing “back” in the direction you are coming from to help ensure not stretching the material. When you get back to the top center of the frame make a tight joint and you should never have a leak. As the spline ages and oxidizes it will shrink and eventually pull out of the corners, and you can just replace the spline.

I have new lenses from another C&C 24 owner he never used before he crushed the boat. So, I have to get all the goup and junk off the frames, get them clean. Then figure out how to install properly. We put a tarp over the cabin to keep it dry with the snow and rain. Looking at what was done by the last installer, does not look correct.
