[C320-list] lewmar portlights

[Warren Updike]

I can second this approach, except that I didn't bother with the inside. I
just picked the gasket from the outside, taped off the hull, frame, and
gasket, then filled the space with black LifeCaulk. I used a plastic scraper
to remove excess caulk and let it cure. The tape came off easily and, as JJ
says, from 10' or even 3' away you wouldn't know the difference.

If the Lewmar port-lights are just leaking then I wouldn't replace them. All
4 of mine were leaking and I fixed them and haven't had a problem in the 4
years since. What you need to do is remove the inside plastic frame to
expose the innards of the port-light. You then need to remove all of the old
calk in that split in the port-light frame, a dental pick works best for
this. You will discover that the material is an "S" shaped gasket and it
takes a bit of picking to get it out...both from inside and outside of the
boat. Once all of the old stuff has been removed tape off the edges on the
outside of the port-light frames. I filled the gap with black 3M5200 but any
high quality calk would work. The calk will ooze to the inside of the frames
so a bit of masking tape on the inside will prevent it from dripping. Once
the calk has cured remove the tape and from 10' looks just like a factory
job! Evidently it is not the bedding which leaks at the port-lights but that
pesky seal between the gap which deteriorates over time. I got this from
Lewmar. It worked on my boat and I know others have done it. Worth a try if
you're looking at a few $Gs to replace them.Cheers and good
luck.JohnM1999#574

butyl tape to rebed them. Easy to work with and now used by many
manufacturers instead of calk. Check out several youtube videos and one
Compass Marine and Sail Rite for instructions on how to use it. I haven't
used Bomar hatch tape but haven't heard any negatives so that is also a no
caulk option.
