Hi all,

We've been battling leaks on our Old Standard Lewmar ports. I was thinking that it was perhaps worn gaskets -- which lead to the discovery that the only company making the older gaskets is Eagle Boat Windows in the UK.

As I was perusing their site I found that they have a number of good write ups around repairing and maintaining Lewmar ports. One of the articles mentioned cleaning and re-sealing the frame joints.

We gave this a shot this weekend, and for the first time in the 3 seasons we've owned our boat we had a soaking rain and no port leaks!

In case this is beneficial for anyone searching for similar fixes the article referenced is here:


After getting these resealed we had a nice (albeit cold -- Lake Superior waters still haven't warmed up) shakedown cruise. The 2024 sailing season on the Great Lakes has commenced!

Doug

I removed the o ring and cut a 1/16" thick neoprine rubber washer as large as the head of the outside mushroom and placed lanoline on both sides of the custom washer and reassembled. No more leaking.
