DUCT TAPE.Really don't want to have to take windows completely out.
I just can't figure out how you'll fix leaks without at least pulling the external frame away from the house.... and if the leaking is in the glazing, you definitely must remove the window. The good news.... it's easy... for safety, tape the outside frame to the cabin so it doesn't accidently pop out too explosively when you break the caulk seal.Really don't want to have to take windows completely out.
I think the butyl tape may be the best bet for me. I went through this last fall and reinstalled using "LifeSeal" caulk. This time, I'll try the butyl tape.Depending on how your port is configured, there are a number of solutions from butyl tape to a number of suitable sealants. for sealants you may want to think about how large the faying (contact) surface is. The stronger the sealant the more difficult to remove it to fix it next time.
If it's an opening port leaking at the opening, look for a bulb seal that will fit. They usually work better than foam seals. Don't overlook the regular home improvement stores for this.

The leaks that I did have came from between the frame and the fiberglass. Those I removed and cleaned and re-bedded with butyl tape I have not had a leak since then.What is the best method when the outdated seals are no longer available?
That is a good lead. Thanks.Never used it but I fink I would try Cap Trolley's. He may look like a nut but others here swear by it.

Easy yes but we had several tries before getting it right, still waiting now for a bad rainstorm to test the very latest attempt. We have also bought a set of portlight visors which should allow use of the portlights in rain but we don't want to fit them until ewe are sure we do not need to do the join seal job again. Lewmar portlights made between 1980 and 1998 were made with a design error and had extra and unused screw holes where water could get below via the frame joins and into the hollow extrusion behind. The portlight visors will also help keep some of the heavy rain off the joins hopefully reducing the pressure on the new sealant as well as allowing the port to be open for ventilation in rainIf your ports are Lewmar, and have a gap between the upper and lower aluminum frames (on the outside) then simply cleaning out the caulk in that gap as best you can, and then re calking will often fix leaks without removing the frames. It is pretty easy and cheap, so I'd try that first.

Uh... what about a garden hose?Easy yes but we had several tries before getting it right, still waiting now for a bad rainstorm to test the very latest attempt.
That's good stuff for deck cracks where a penetrating epoxy is needed. Not sure I would use it in this application.That is a good lead. Thanks.
Of course, why didn't I think of that!. I want the real deal not a simulated hurricane. I'm not sure if a constant gentle drizzle is worse or the shorter lived but horizontal wind driven tropical storm rains, Once we fit our new visors access with a sealant tube or caulking gun will be difficult and those visors are designed to stick on once and stay put!Uh... what about a garden hose?.

In one of those videos they show him using it on trailer windows.That's good stuff for deck cracks where a penetrating epoxy is needed. Not sure I would use it in this application.
