Leaking portlights

I recently purchased my first boat. A 1985 Catalina 25.
The port lights are leaking and I would like to do the full re-seal kit from Catalina direct but winter has descended VERY quickly where we are and I would like a quick easy solution to keep it dry over winter until I can do kit.
Is there something I can use to temporarily seal around where the glass and frame meet that will not make my life misery in the spring when it warms up again?
The boat is not covered and is not likely to be either.

Re: Leaking portlights

Whatever you do be sure NOT to use silicone.
Don't temporary seal, will be just more residue to remove.

Short of covering even portion of boat where ports are leaking (recommended)
If quick n easy your looking for...just seal around ports with robust tape and discarded shrink wrap or other.

Re: Leaking portlights

Glad I asked as silicone was what I was thinking.
Thanks for the advice.

Re: Leaking portlights

As Hugosalt said. That's not a big boat, a 6x8 tarp is probably enough. Lay the tarp right on the cabin top and a bungee cord at each corner running to a hole in the toe rail or stanchion base. Alternatively, cut plastic pieces slightly larger than the ports and tape them in place.

Blue painters tape can be a good temporary water stop for this kind of leak also, and fairly easy to remove in the spring.

Re: Leaking portlights

cbutty...highly recommended by all not to use silicone anywhere on boat as leaves residue that nothing will adhere to
including new silicone, and extremely difficult to remove. Much has been written on the evils of silicone on boats.
(except for very specific plastic ports/Beckson ports come to mind.)
Many experienced pros recommend using Buytl tape, again much written about benefits of using Butyl,
but needs to be used with mechanical fasteners.

Re: Leaking portlights

I use "Bed It" butyl tape. You'll have to remove the frames and panes to install it. As HUGOSALT notes above, the mating surfaces must be squeezed with fasteners. It seems the reason many use silicon or 5200 is the expedience of just gobbing it on from the outside without removing the fixtures, but those "solutions" are only temporary. And 5200 eventually turns to powder. Butyl seems to last a very very long time, and it's resilient enough to maintain a seal with flexing and thermal expansion. I've used it to seal small cracks in my hull-to-deck joint sealing (compressed by a rub rail), chainplate deck penetrations, and port lights -- all areas that undergo a lot of flexing -- without further leakage. I've pulled stainless hardware off that I bedded 10 years ago, and the butyl was still hanging on tenaciously.

Being fully aware of the drawbacks, I have used Dow 795 construction silicon in a few places where I could easily abrade it off later.

Re: Leaking portlights

Tape A sheet of plastic over your ports using a good tape. Yes, tape will leave residue but you can clean it off later. It’s usually a better solution than taping the port light fixture Itself. Or do both.

Look for a Whizzy Wheel - or similar - to remove the adhesive in the spring.

Re: Leaking portlights

I would also use tape and plastic sheeting. The residue from the tape is a lot easier to fix than the water damage you'll have below after a winter of leaking. Goo Gone works well.
