[C320-list] Lewmar port gasket replacement

[JJ Morrison]

All four of the portlights on my 1999 320 were leaking when I purchased it. The fix (which has been previously documented) turned out to be the replacement of the gasket between the split aluminum frame. You need to take off the plastic frame on the inside of the cabin portlights so that you can see what's happening. The gasket needs to be picked out from the outside with a dental pick or some such tool the shape of this gasket is like a double S very complicated. Once the gasket is out you need to tape off the edges of the gap between the frames and proceed to fill the gap with black 3M 4200( or other similar caulking). You can have someone on the inside to indicate that the caulking is oozing through (I didn't and used a bit too much caulking). I did this in 1999 and nary a sign  of a leak to this date; from 10feet it looks like a factory job!
Good Luck
