With this being my first season as a bigger boat owner (the boat and maybe me too) I've been reading about how my AC, electric toilet, and engines, etc have access to raw water through sea cocks. The more I read, the more concerned I get about being responsible for their management and maintenance. I'm glad to check them but I don't have the slightest idea where they are. I've got a 1990 Carver Montego 3257 and would appreciate somebody telling me where to look. Any emergency prep you can offer would also help.
