Leaking port lights in Lavezzi 40

After days on starboard tack in pretty big seas, both of the oval port lights on the starboard side began to weep. It is obvious that they (and, while we're at it, the ones on the port side) need to be re-bedded

It looks to me that the lens is held in with puttied over screws from the outside. Once the screws are exposed and extracted, does anyone have any experience removing the plastic without destroying it? Heat? Pushing from inside? anything else? The lenses themselves seem to be in good shape and I would rather not replace them.

Thanks for help from anyone who't been there or done that on this model.

There are no screws the screws where used to hold them until the adhesive dried. The plastic expands and contracts with tempeature and would crack if left in.

You will have to cut the glue between the hull and the lens. A hacksaw blade with a handle made of tape or seizing wit run through with one person inside and one out pulling back and forth will get them out.

Once out you will need to clean up both surfaces. Take the time to polish the lens as well.

FP used a thin weatherstrip on the inside to keep the adhesive from leaking out on the inside. Tape off the outside around the lens. You can temporarily screw it in place for this. You may want to add a couple more screw holes prior to reinstalling.

Put a liberal amount of adhesive on the window screw it in place and let it dry for a couple of days. Dress the caulk outside while it's still wet and remove the tape after about an hour. Clean up any excess.

Use a good adhesive, we usually use life seal I beleive. I think 3m 4000 uv would work as well. Dow has an OEM product that sucks.

Remove the screws after two days and fill those holes.

Can't edit on the phone ment to type seizing wire to cut.

Re: Leaking port lights in Lavezzi 40

Hi Grateful and captainjay!

We are having the same leaks our on Lavezzi and are looking to re-bed our windows too. Unfortunately, our leak has let in some water behind the wood panel wall in the aft cabin, so we are hoping to remove the white plastic window cover and wooden panels to allow everything to dry out. We removed the screws in the "chair rail" that is placed over the point where the lower leather meets the upper wood paneling, but before removing with force, were hoping you might have some advice on removing it as it is still stuck to the wall (maybe it was glued by FP)!? Any tips on removing the white inner window cover would also be appreciated as it doesn't want to pull off very easily, are there locking snaps or tabs inside it somewhere, or maybe you can remove it after taking the window out???

Would love any other tips you might have on this project!

Re: Leaking port lights in Lavezzi 40

Both pieces are likely glued with sikkens. The French equivalent of 4200. The trim ring will likely be easier to get out after you take the window out. You will be able t see behind it from the outside and cut away the glue. It is not likely that you will get the plywood paneling down without destroying it. If it's not badly stained then I would just put a dehumidifier in the room for a day or two and leave it alone.
