Thanks for the input on my prior problem

I have another problem that I thought might be one someone else might have encountered. My port side interior light - over the dinette table - has been filling with water. Any idea where this leak might be originating? Where would the best place to start looking be? I didn't want to just caulk up the screw holes without fixing the source of the leak.
Any help will be greatly appreciated!

Most likely possibility would be the port side chain plates.

Chainplate entry points are on the deck.
Which are well below the ceiling light... (If it's like my light over the dinette). I'd guess the mast base fitting or perhaps hatch slides.

Water can seep into the coach roof at any point where a cleat or other hardware is mounted and can travel between the roof and the liner. The most likely culprit could be the handrail mounts on the port side. The water could find its way to the wiring and into the fixture. The solution will involve removing all that hardware and re bedding it in 4200.

I had a similar problem only with the starboard light filling up. Turned out to be a leak around the window above it. I fixed it by rebedding the window, a fairly easy task. The window is held in place by a series of self tapping screws on the inside which screw into the window flange and not the fiberglass. I removed the inside flange, used a putty knife on the outside to break the remaining caulking, cleaned up the old caulk, and replaced the window. Hope this helps...

Hi Larry,

From your description of the light, it sounds like you're talking about the light in the ceiling of the salon, about a foot away from the compression post ... right? I think the most likely source for your leak is at the base of the mast.

The mast tabernacle is attached to the cabin top with four large screws, and it is fairly common to find some leaking and/or dry rot there ... mine ripped out once when I was raising the mast. It is easy to fix in most cases. I simply drilled small holes 1" to 2" apart in the area covered by the tabernacle, saturated that area with "Git Rot," filled the mounting screw holes with epoxy so the screws would hold again, and then I rebedded the tabernacle with 3M 4200. For a really bullet-proof installation, you can through-bolt the tabernacle, but I didn't think that was necessary.

'Hope that helps ... good luck with the fix, and welcome to the group!

Buzz & Larry,

What vintage are your C25's. My 88 tall rig has the salon light under the port side weather deck near the chain plates and my mast tabernabcle is through-bolted.

Larry,

I agree with the others that something(s) on your deck need rebedding. As for<blockquote id="quote">quote:<hr height="1" noshade id="quote">What vintage are your C25's.<hr height="1" noshade id="quote"></blockquote id="quote"> Al has a good point. The C-25s were build over a period of years. There were small changes from time to time. It would help us help you if y'all would remember to include your model year and relevent factory options (rig, keel, interior type, etc.) when enquiring about a specific fix.

As you follow the discussions on these forums, you'll start to notice which features changed over the years. I think someone made up a list of features vs. production years, but I don't remember who or where right now.

I had water in the light in the V-berth. I traced it to a leak at the deck connector for the mast lights - the water was following the wire bundle to the light.
