Greetings

I have a late 80's vintage Sea Ray 300 Weekender with the long,
rectangular side windows.....Of course, there are notorious for
leaking, and mine are now leaking in the worst of places, right above
the electrical panel and A/C controls.....

Finding the source of the leak has been all but impossible so far, so
I was wondering.....Is there such a thing as a water-thin sealant that
I could pour into the window channel, let it work its way through the
leaks, cure, and eventually seal them?

The side windows likely haven't been opened for 10 years, so I'm not
concerned about their operability....I just want the leaks stopped,
and I'm tired of spreading caulk to no avail....

Thanks in advance!!

I own a tug/trawler built in Taiwan about 5 years or so prior to your
Sea Ray. Folks who own and for some weird reason love this genre of
boats have been known to call the windows "leaky teakies", as they all
eventually develop leaks around the frames. Your Sea Ray has different
framing material, but the actual solution may reside in pulling and
rebedding the windows. It's tough to get enough goop in behind the
frame with an exterior application. Maybe something like "Creeping
Crack Cure" or similar product might work- but most of the time the
only real solution for a leaky window frame on an older boat is to
pull and rebed it.

If you see "tea" colored drips coming out from the window, be prepared
to deal with some rot already promoted by the leak. The worst thing to
do in that case would be to gum it up with silicone enough to
temporarily stop or slow down the leak and then pretend you have
solved the problem.
