Hi everyone! I am sure somewhere back in time this has been covered. I am new on here and we just got an E27. The portlights have corrosion and have been dripping for quite some time. I have seen conversation on just about every model but the 27 specifically. The owner's manual says they are "floating windows." We have removed them but where do we get the replacement gaskets? What is the best procedure for doing this correctly? We are thinking they are Lewmar portlights.
