There may be other uses we are not aware of. They may also not have been used every year the boat was produced.

Port Identification Information:
• Outside of mounting flange (measured on the outside of the boat): 425mm x 191mm (about 16-3/4" x 7-11/16")
• Cut out size: 405mm x 171mm (about 15-15/16" x 6-3/4")

Please note that these ports are built in England and made to metric system standard dimensions. All Imperial equivalents are approximate.

1) Boats built before 2006 used several different aluminum framed versions.

2) Depending on the size of the port, may include tape to install between the frame and the gasket as shown in the attached installation drawing in "Technical Support" below.

3) The related installation instruction drawing shows protrusions in the gasket where it interfaces with the lens and appears to be for an earlier version of the gaskets as the currently supplied replacement gaskets do not include those features. Lewmar Size 7RE Stainless Steel
