Hello all,
Have a window with a gasket that is coming undone in one corner. Picture does not do it justice but hoping someone has experience with these windows. The gasket piece has to be inserted into a channel…… can’t figure it out. A special tool?
thanks
Greg

You might try warming it (agressively) with a hair dryer. Once it is soft, you may be able to pry it in with the flat blade of a screw driver.

That is a Portal and not considered a window.

A Portal is "Water Tight" like your hull.

Is the Portal leaking?

Sorry for the lack of proper verbiage...... Yes the gasket for the portal is coming undone in the corner

Thats a good idea with the hair dryer, Thanks! Its such a strange design.... the slot where the gasket is suppose to slip in is in a strange place.... mid gasket. I'll try and get a better picture but in the second picture you can see the slot. The gasket has a small lip mid gasket that goes inside.

A "portal?" I have never heard that term in the context of boats. Do you have a reference?

I think you have to push it in with a plastic roller tool but be sure not to puncture the gasket. A screwdriver is discouraged if it is sharp enough to damage the gasket. I'd guess that if the gasket has come out, it is damaged and can't be re-installed. I just bought a new gasket. Good luck! I have one to replace, too.

It is probably one of those autocorrect issues. The word is porthole (PORT-HOLE)...

It's funny that when correcting someone else's terminology, the correction is incorrect. :)

Autocorrect... it can be your worst enema. :poop:

(I know.... I know... I over use (or is that overuse) that one but... I can't help it.)

You may be right….. these are original from 2005……. Another job, but thank goodness this porthole is in the cockpit under canvas. Gives me time….

I had the same issues and you can fix this too. Go to the auto parts store and ask for 1/8 inch silicone vacuum hose, about 4 -6 feet cost you about $5-6 dollars. Cut to size with about 1/8 inch extra to fit the channel. add a little RTV sealant to provide a seal between the two ends. and you're done. I did this to all my portlights about five years ago and not a single drip or leak since. I'll try to take a pic of the port and a picture of the vacuum hose later today.
