Small leak of water in our bedroom , any ideas?

scousine

We just bough a month ago this boat and as any boat of that many years there is always little things that comes up (hoping they are all little ) We noticed the rug in our bed room, small spot was wet and dried but still a small wet spot bottom right of this picture in front of the cabinet. As there is a sink in the cabinet with water coming in through pipes ,our only thought is may be a leak there. Anyone ever had this situation .

Check the sealant around the port lights on the boat. If you have any gaps between the white plastic and the stainless beauty ring, water can get in there.

 I spent a year on this. I didn't listen to everyone else. Here's my advice.

1. Sit in the boat with nothing else on and listen to hear if the fresh water pump kicks on.   - My hot water fitting in the bathroom was leaking.  Inspect EVERY hose fitting at the sinks and see if there's a leak. If the pump does not kick on at all, then it probably isn't it. 

Then:

2. One or two at a time, seal EVERY SINGLE SCREW on the outside, windows and rub rail.

If it's not fixed continue.

3. Reseal windows.

If still not fixed, the last thing is the bow rail screws.. hopefully it isn't that because they are pretty impossible to get in and out as one of them always ends up spinning in its hole.

Lets just hope it's fixed by #2.

x2 on what @J3ff said but would add the windshield screws under the vinyl covers, any snaps screwed into the deck to re-sealing list. I also sealed the three hatches with butyl tape. I did all those over the off season and no water this year.

I think i might have found where the water is coming , even in my engine room above water line where there is the gen i can see water after it has rained . What sealant would you recommend, i think i have a silicone job needed here

4000 UV. Remove as much of the old caulk as you can. Use masking tape to get a nice result.

Use 3m4000uv to rebed that area. Do not use silicone. It will make a mess and you will not be happy with it pealing in a few years. Be sure to tape the area off with painters tape so your job looks professional when finished. The covers for the vents do come off. Take out the screws and slowly work it up. There will be sealant underneath, but the job will turn out better if you remove and reseal it. Just my 2 cents worth.

I redid that exact same area on mine last with  4000UV and I'm not happy with it.  I need to redo it.  I did not remove it first as Greg suggested, so maybe I'll have to try that.  Although I do not think water can come into cabin from that area, it just keeps it from entering the blower vent area (not always a good job of that either).

The 4200UV is not really a ‘caulk’ per se. Been there too. lol. Be better off with a true marine caulk like boatlife. You can get it UV resistant too. 

I did my blower vent covers with butyl tape finally.

The only other item i would suggest that hasn't been mentioned here is to fill that sink with water. Open and or remove all the drawers and then let it drain.  See if you have a leak around your sink drain fittings or through hull.

Ok bit of a surprise last night it had not been raining for several days and while today I planned to seal as much as i can,  notice the small area in front in the cabinet in our room was wet again? Could the AC in the bed room have anything to do with this. ( still will seal what i can because there was also water when it rained in the engine room where the generator is above the water line (stbd)

It’s possible that the drain for the ac pan is clogged and is overflowing. Not sure if that water can get to the carpet though.

Correct, no entry to the cabin.  Here's what it looks like (on a 370).  Solid fiberglass except for the two blower hoses.
