We are ending our fifth year with the NFM stainless ports. They have exceeded my obscenely high standards in every regard, well, except for the screens. They look as good today as the day we installed them and have never once leaked a single drop into our boat. On our boat, not an Ericson, they added huge $$$$$$$$$ curb appeal. We get more people asking us what our boat is and telling us how beautiful she is with the NFM's than we ever did with the POS Beckson's..
BEFORE NFM:
AFTER NFM:
If you wipe the window gaskets frequently with 303 Aerospace Protectant the rubber will likely last indefinitely. Every time I open ours I wipe them with 303 before closing them, takes all of 2 minutes or less. The gaskets have NEVER once stuck to the SS and literally fly open if your not careful.
The company can be slightly "flaky" during the ordering process, though perhaps that is better today than 5 years ago, but the product is literally bomb proof....
