Wondering if anybody can help with this as I can't find anything in my manuals or from watching videos on you tube.
Model: 2022 Cougar 364BHL
I'm looking for the black tank flush for the rear black tank. I have one labeled tank flush, which I was told was for the front black tank. There is a similar looking port to the right of this. I'm guessing this might be the rear flush, but would love confirmation before I screw something up. Anybody out there know for sure?
The unlabeled port is in the photo below with the red arrow pointing at it.
