My boat is temporarly moored in the Port Washington area of LI Sound. Does anybody know of a marine pump-out boat that can clean out my holding tank. The boat was launched last week and the PO did not have the tank pumped prior to hauling. No ordors until the boat was launched. I also found that the head was in need of replacement. With the water inlet closed, the head keeps filling up with fuid and other stuff from the holding tank. I do not mind replacing the head and hoses, however I would rather work on an empty system. With all of the boats moored in this area, I would have to think this service is available. I am not used to this as I am planning on returning to the South Shore in the next few weeks. There the pump-out stations are on the docks.
