Part #: Z3787
$65.99
This gasket fits the Lewmar 7-1/2" x 16-3/4" stainless steel opening port. Catalina started using these ports in April of 2006. They replaced the older aluminum framed ports and use a different style gasket. New Standard ports secure closed with two dogs which close by pushing them toward the lens with your thumbs.
Known Usage:
• (4 ea) Catalina 315 and Catalina 355
• (6 ea) Catalina 350, 400 and Catalina 42
• (8 ea) Catalina 375, Catalina 385 and Catalina 445
• (9 ea) Catalina Morgan 440
• (10 ea) Catalina 470

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")
