[C320-list] LEAKING CABIN PORTLIGHTS

[sail-ability at sympatico.ca]

Jon;

 By horizontal slots I'm assuming you mean the ones on the outside frame? Evidently
some of these had a plastic insert which deteriorated over time. Mine seem to be filled with a butyl gray putty. Do you remove the  frame to do the slots or just remove the old material and then fill in the slots?

Thanks very much for you help and interest.

Cheers

JohnM

I ended up doing an entire upgrade to 2 of the ports (re-bedding, changing the gaskets and redoing the horizontal slots. After doing 2, that way it was becoming obvious to me that the horizontal slots were in fact the problem. So on the last two I tried just redoing those before going through the hassle of doing everything--it worked! Redoing those slots takes about 30 minutes, including taping and it solves the problem.

Getting the old silicone out and fitting the new gaskets turned out to be much more difficult for me than others have experienced--so I'm elated I don't have to do this for the other two. Hope this helps and if you need more info., just let me know...
