+1 on Scott's post. When I bought my boat in 2018 one of the first things I did was rip out the stinky macerator that could never be pumped clean and capped off both the black tank outlet and the thru hull. No sense in replacing what I'll never use on the Chesapeake, and take a system out of the boat that has no need to be there. Simple matter to uncap and rerun a macerator if I was ever to want to go offshore (unlikely).I removed my macerator and capped the tank long time ago. The hose to the macerator was downhill so would fill and not get pumped out. Like you, on the Great Lakes so will not be used. Easy to install if ever needed in the future.
You may also want to check all your other plumbing hoses. The clear hose with black spiral galley drain started to crack so was replaced with better hose. I also replaced all the head intake and head sink drain hoses after the head intake had a leak.
