    Bomar Deck Hatch.....-gctid376267

    So Im having some leak problems in the master state room from the rear corners of the bomar hatches.

    I know that sometimes it is leaking under the flange where the hatch meets the deck, but after inspecting them, i can see no cracks in the caulking.

    So first i'm replacing the rubber gasket and also re-bedding the lexan. i would really like an alternative to the black embedding (tar like) material to set the glass into.

    Has anyone ever used marine silicon??? The black stuff is so messy and down here in the baking sun, it constantly eeks out and makes a mess.

    Any suggestions would be appreciated!

    I have the same issues with all three of my hatches on my 38. Next week I will make the trip to home depot to replace the weather stripping but I suspect I will have to re-seat all three of them as-well. I was planning on using marine silicon so I will be very interested in what others have done as well. Good-luck..

      I think you should remove the hatch frame and re-bed the frame. Life caulk and west Marine have poly sulfide caulking that is better than silicone for both the plastic and the frame. There is wood backing in the deck that can get water saturated and rot. If your experiencing leaks now wait until the backing rots and you're into major work replacing the deck coring. Re-beding the hatch is fairly simple.

        I would not recommend silicon. Use something like 3m 4200 or 5200. This stuff works much better and lasts much longer!

        If you contact Bomar they sell the material they use in the original installation.

          5200 to embed the glass, really? I thought it hardens too much to float the glass, but maybe not. i just dont want to use the black tar stuff since it melts so much.

            I heard about life caulk on some internet searches. its good to embed the glass too?

            If I can get the hatches up off the deck, I will rebed them also. Just really wanted to seal the top and the glass first to see if thats where its leaking.

            thanks!

                For the flange to deck try Captain Tollys Crack sealer. Can buy at West Marine. It will seal any small cracks in the caulking.

                    bought some Life Caulk today and going to give it a try tomorrow! I'm also going to get some of that Capt. Tollys crack sealer.

                    it just sounds like something i can try instead of pulling up the hatches, which after 8 weeks of boat projects, i'm just not up to right now!

                    Thanks to all for the tips!!!

                    Let you know how it turns out!

                      So I took out the black gaskets and removed the lexan and spent a whole day getting the black tar stuff off the gaskets and lexan.

                      Another few hours getting it off the frames.

                      I decided to use the Life caulk as a few of you recommended. I super glued the gasket back on the frame, as i saw recommended on a few web sites.

                      I put a heavy bead of the Life Caulk around the top at the gap between the glass and the alum. frame.

                      I cant believe this is the only thing that holds the glass in the frame?

                      As soon as i finished the first hatch it started raining, not hard but i will see what happens.

                      Tomorrow i will test it out for leaks and hopefully be finishing the other hatch!

                      Thanks for all the suggestions!

                        Tested the hatches and everything seems to be waterfroof! The Life Seal has a good seal and seems to be holding the glass to the frame.

                        Thanks for all the help and to Scary for suggesting the Life Caulk!

                        Hope i dont have to mess with the hatches for a couple of years!

                        Cheers!

                          Thanks for the update ED. This is on my short list for the very near future.

                            Where did you find the rubber seal? I have a 3388 bow hatch seal that ripped and needs replacing.

                            Thx
