2012 Coastal 290 - Overboard Discharge Y-Valve location
2012 Coastal 290 here. Attempted an overboard discharge recently (20 miles out) and it failed with the pump triggering the breaker in the switch. Got some feedback over at the TheHullTruth that the boat should in fact have a Y-Valve somewhere that needs to be set to enable the overboard discharge.
I have invested a good amount of time looking for said valve behind every hatch and access cover to no avail. Does anyone have experience with this particular boat around this model year? Any idea whether the boat in fact has said valve and if so where it is located?
Thank you!

Re: 2012 Coastal 290 - Overboard Discharge Y-Valve location
I located what appears to be the discharge pump. It's a Sealand TW pump located on the starboard side under the live well. I haven't been able to trace where the outgoing hose routes to. I did find a Wellcraft owners manual that indicates that the discharge outlet is on the port side. That would seem very odd.
Unfortunately the Achilles heel of this boat is the very limited access to anything in the bilge. It makes some basic things like tracing a house overly difficult. I'm planning on another attempt at tracking the outlet house from that pump with an endoscope camera.
Thanks for the tip on the slot at the bottom of the pump. Will give that a try as well.

The toilet itself works completely as expected. It is able to generate, keep vacuum and flush. I have also successfully utilized a pump out station. The part that doesn't work as described in the original post is the overboard discharge.
Now better understanding the setup, it is looking more like the issue is with the discharge pump itself.

In this particular case, the TW discharge pump was seized which explains the triggering of the breaker. Replacing with a new pump addressed the issue. The pump is on the starboard side of the boat under the livewell. Access to it required removal of the livewell.
