Lewmar Ports and Parts


Lewmar ports have been the industry standard for boat builders since the early 1990's. They are divided into two models, Standard and Atlantic, and each model has two versions, simply referred to as Old and New. We carry parts only for the Standard Ports. Atlantic parts can be difficult to find and we recommend you contact Lewmar directly to determine availability.

Step 1: Identify your port

All Lewmar ports have an aluminum exterior frame. If your port has a plastic body, chances are it is a Gray or Beckson port.

There are two models of Lewmar ports: Old Standard and New Standard. Please use the photo below to identify your port.

Lewmar ports will have the dogs (knobs) show below. the dog on the right may be metal or plastic, but will flip up and down to secure or open the port.



Sizing guide

Please measure exactly as described here! From outside the boat measure the outer edge of the port frame as shown.

Complete ports

Complete ports come with everything: the port body, lens, trim ring, screen, and gasket. Installation adhesive is not included.

New-fangled screen installation instructions

The new Lewmar port screens (which really are better) seem to confuse everyone, so we prepared our own, supplemental installation instructions. Between this and the Lewmar diagram you should be all set.
