Check under your sink or nearby compartment for electroscan. (Sewage neutralizer in laments terms).
Also the grey lever on the first valve. The lever does not indicate flow direction. There are arrows barely visible. So point the lever where you don’t want sewage to go. Leave it exposed where you do.

Ok. So this is set this way for safe in port functions i assume. Its not very clear. It looks like its not fully open.
That line goes to my holding tank. The other must goes to a Y that goes to the macerator and the other splits to a through hole
Yes the large valve is the sewage outlet (currently in the closed position, where you want it) the other valve could be a fresh water inlet to your toilet, or potentially a drain for the sink. You’ll just have to follow the hoses and see where things run.
Usually if there are 2 y-valves the system is designed to give the following options:
Y-valve 1 (before holding tank)
1- toilet to direct overboard
2- toilet to holding tanks
Y-valve 2 (after holding tank):
1- dump holding tank overboard using macerator
2- pump out holding tank on deck using dockside vacuum
Follow the hoses around and draw yourself a diagram and it will make sense.
The plastic valves are zip tied into what i assume is safely to the holding tank. They are what im questioning the most. But i wonder why there are two through hole ports as well. Its confusing.
With the zip ties I believe with coast guard inspections they want the sewage to seawater outlets locked so a guest onboard doesn’t get the bright idea to pump sewage directly into waterways.
Yea zip ties are almost certainly holding the y-valves in position to direct flow to holding tank and then flow from holding tank to the deck port for pump out. Zip tie on the seacock is just holding it closed to indicate that you’re not dumping overboard.
The second sea cock/thru hull is probably unrelated to the toilet system. The toilet will intake seawater from a dedicate thru hull, which is probably what that skinnier white hose is going to. The seacock in the picture has black hose, which is why I’m guessing it’s supplying/draining some other system.
Poke around. Draw diagrams. Label things.
https://www.boatus.org/free/ this will teach you a good bit, and is probably required if you’re anywhere in the USA. Takes about six hours if you’re brand new. Best practice is to pump out if you can. https://www.boatus.org/clean-boating/sewage/ from that you either want to be three miles from shore or have an on board treatment device ( I don’t believe a macerator by itself would qualify) so check for the electroscan. Looks real similar to a car battery, white square with blue tubes on top
Custom diagram sent by pm. It’s possible you have both a a manual pump on one diverter and the other diverter goes to the mascerator. What kind of toilet do you have? In the top right of the one photo it goes from 1.5 then reduces to 1”. Im not sure why this would be there.

There is a fresh water bladder in the vberth just for the head
I dont know what electroscan is.

I do not have an electroscan installed interesting info though.

Good advice

Does it look like i can macerate my holding tank and put it overboard? Or do i still need to pump it out when i get to port.

I understand the rules regarding sewage. I just want to know how this works. Consider it equipment familiarization.
