Hi I just purchased a ’91 23 Open and the macerator was missing from the forward fish box plumbing. The boatyard I used ran the hose from the foward fish box drain to the macerator/pump and the outlet of the macerator pump to the portside above waterline drain. I do not have a switch position for the macerator and they disconnected my lights to power the pump (nice huh?). I am trying to figure out how to fix that.

My live/baitwell drain goes to a below waterline thru-hull seacock. I only have one bilge pump so can’t help you there.
