We have a 2001 Hunter 260. At the end of the season the marina's pump out was not working so, unfortunately, we had to bring the boat home with waste in the holding tank. It is probably 1/2-2/3 full, should be all liquid. We tried to pump it out ourselves at home but it doesn't seem like I can get the tubing/hose to pump it out into the holding tank. There is a good 90 degree bend in the sanitation hose right before it enters the tank. When I put the hose down from the deck there is a stopping point but then when I twist it and jiggle it around I can get it to go just a bit further so I thought I was making it around that bend but then when we started the pump we don't get any discharge. The pump is functional, we tested it pumping out a bucket of water. Is there a valve of some sort between that sanitation hose and the tank? Any other ideas how to get this emptied? I called a porta potty company to see if they could do it and they said no. I had a septic company come out and he said his minimum charge is $250 (!!) which would be okay if he could also do my septic system but he can't because of the absurd steepness of my gravel driveway. If worse comes to worse it can probably sit all winter because we keep the boat in a pole barn and it shouldn't freeze in there but obviously that's not the ideal solution here. Thoughts?
