Port hole install

[JustJeff017]

I am replacing all four of my port and starboard side windows towards the front. I am getting the plexiglass but I want or need to know how to do this and what exactly I may need. The boat is currently in the water so with any hope I won't have to haule her out. Any and all help is much appreciated. Sorry about he typos, this forum is not IPad friendly lol

I replaced all of mine...I don't know if yours are similar, pita job but they were leaking. You have to take a tool like a stiff putty knife to break the caulk seal, then take out the screws. Now mine had little tiny "nuts" that were imbeded in the caulk under the ss trim rings, and I lost a few....they are impossible to find anywhere and I had to make some new ones. clean up all the mess and rebed with 4200 or something similar. If you do this in the water, you are going to need a finger pier...I wouldn't try this off a dinghy. Hope this helps. By the way mine had a rubber gasket and I was able to buy new replacement from the manufactuer.

Make sure you use 4200 and not 5200.

Here is a fairly detailed article with advice on replacing portholes. He uses butyl rubber as the sealant. I really like butyl rubber as a sealant over a polyurethane sealant.
