macerator is a device that chops up the poop before dumping it ooverboard (illegal in most places)
sump pump I dunno
As for pumping overboard, I know its banned almost everywhere, I don't know what your location is, but I mean really, a 30 dollar pump out is alot nicer investment than your poop in the ocean for everyone to swim in... just a thought
Email glastron and they will send you an owners manual for the boat that will have all the instructions.
