The dates these portlights were used by Catalina on each model were not recorded. We know that Lewmar produced the Old Standard portlights from 1982 through 1999.

Refer to the additional images at the left for a photo of the Old Standard style portlight to ensure this kit is correct for your boat.
1) Don't assume your boat uses these portlights based only on the year of your boat. Catalina might have had a different brand of portlight on the shelf which they used until their supply was exhausted at a later date than the manufacture date indicated.

2) Kit includes a length of gasket that is trimmed to fit the specific portlight on which it is being installed along with the glue to glue the finished ends together.

3) Careful attention must be paid to how the gasket is installed in the frame. There is a definite cotrect orientation as the gasket has a high density and a low density side.
