OK, sounds like that mystery is solved…I would have to look at it closely but I think it makes sense. Water exits powerhead adapter through that hose you had blocked off, then off to cool the exhaust elbow…
I see that the heads to this unit are vented, tied together, then exit through the elbow/muffler as well…
