Haven't had a leak yet.

However, you must be sure they are bedded properly (as with any ports). I
experienced a couple leaks even though
they were bedded in 5200.

I think my problem was the LP paint on the fiberglass surface didn't allow a
good bond for the 5200. When I reseated the leaking ports, I cleaned the
painted surface with acetone and that seems to have resolved that problem. I
also cleaned the surface of the bronze to make sure there was no
contamination there as well.

I might mention that my experience with a total of 8 NFM rectangular ports.
The over all quality was good and when I need a replacement spring for one
dog (lost), Richard provided several. He also provided a special wrench for
adjusting the hinges.

Hi Steve:

I read on a past post that you had a few NFM ports installed on your
boat.

How are they working now?
