CKARMA4, my 2006 350 #393 was leaking at the port light seals. I ordered new seals from Lewmar which were obviously bigger than the old seals. I found out they changed the seals in 2007 and they do not stock the old seals. They recommended that I shim out the catch block on the latch. This did not work. I recommend anyone who owns a pre 2007 boat not to waste your time and money on so called replacement seals from Lewmar. I cut out the section of the old seal that was compressed by the hinges and filled the gap with rubber compound. This stopped the leak, at least temporarily.

Hi there,
I had similar problems - also on the port side. I took a piece of the old compressed seal to West Marine, they went to their catalogue and found a close match - a little bigger -and I fitted it. Cant recall what I sealed it up with, works fine. About 5 years ago. I think you may be able to get the seal at big marine stores such as Fisheries Supplies in Seattle. Same issue with the Refrig Seals.

Ken, I replaced a couple of my Lewmar seals 2 years ago with these - https://www.defender.com/product3.jsp?p ... id=3962096. Being new rubber it took a bit of effort to close the port initially but after it compressed I've had no problems. My boat is a 2005 hull # 351.

I know this is an old posting but I've got the replacement gasket information you will need to replace the ones on the opening ports. My boat is a 2006 model year. The ports are Lewmar's "new standard". You can purchase the old style gaskets for these ports on eBay. Here is the link. They are exact replacements and sold by the foot. I replaced the gaskets on all 6 ports. I found it easiest to just remove the entire port and then remove the clear lens. I followed the directions I found on Catalina Direct. They even sale kits for the job. Their gaskets are not the correct gaskets and do not work. (I found out the hard way). But, the process they laid out was very helpful. I rebedded the ports with butyl rubber tape. Just FYI, it was a tedious job but the ports are ready for at least another ten years. Here's the link: https://ebay.io/m/CZgj3S. I wish I would have had this info before I started the project. I hope this helps someone.
