I spent a few hours one afternoon and removed the old silicone that was holding the lens in place, removed and cleaned the lens and the frame and used 3M 4000 in black inside and out. No leak since...not even last night with all the rain we had. If you haven't done so yet, have someone stand topside and run a hose over the hatch and observe where the water is entering.
Sorry, Tardis ... I didn't see your post at first. I have the Bomar High Profile hatch, Bomar is currently selling a 2000 series that looks pretty similar even 34 years later. Yup, I think that sounds like what I have to do as well. Were you able to lift out the lens simply by digging out the caulk from the outside?
