Hi All, We just purchased a 1997 Doral 270 SC and I'm trying to figure out how to empty the grey and black tanks. It looks like they both have to be sucked out but I was told by the someone that the grey can be emptied into the water, not sure how to do that. There is also a macerator but I don't know how to use it, any help would be greatly appreciated.
