I have most of the paperwork for this (including the Yanmar manual), but no owners manual for the vessel. Most immediately, I would most like to know where drainage from the ice box and kitchen sink goes. The starboard bathroom sink drains directly overboard through a port on the starboard side. Do the ice chest and kitchen sink *both* drain into the bilge? Or do they have another drain path? I am concerned because my starboard side waste port has been blocked, and the pump-out waste system rendered inoperative (replaced with a Portapotty). I'm worried that the kitchen and ice liquid wastes may be going to a tank that I cannot pump out.
