Head ID
The other forum where this question was asked mentioned an old Raritan Model that may be original to the boat. There was a link to buy new parts including the plunger housing for $118. The porcelin itself looks ok. As a comparison, you can by a complete new head w/bowl for $142 (Jabsco) at West Marine. Regardless of what brand, if you decide to go new, the heads come in a box and some assembly will be required. Be prepared to drill new pilot holes if the mounting base measurements don't line up. I just did my head and there are lag bolts that bite into the fiberglass. There is no backing plate or backing nuts. Best of luck!
