"Bawoosh Effect" I love it, we have definitely added a much needed new phrase to our collective Hatteras language.
It is, as described the build up of cooling water in the vernas. Vessel trim, list and loading can impact this as well. increased back pressure of a more deeply laden vessel could decrease the Bawooosh-es.
Im still chuckling at the bawooshes, I may start mine up just to hear them Bawoosh.

Re: Muffler orientation
Because of this, before firing em up I check to be sure no one is behind the boat dockside. A really good BAWOOSH sends water clear across the dock.

Re: Muffler orientation
The flow direction on mine is fine. But according to the instructions for the late model Vernatones, the label is supposed to be on top AND they're supposed to be oriented horizontally (on a boat?) or tipped slightly down toward the outlet.
I think if I did that, though, I'd have no BAWOOSH.
To BAWOOSH or not to BAWOOSH, that is the question:
Whether 'tis nobler on the docks to smoothly flow
The rumbles and raw water of two-stroke power,
Or to rotate one's Vernatones against a sea of backpressure...

Re: Muffler orientation
I've got the same symptom. Only one side sneezes at idle. Been that way for years and hasn't affected performance. When we push the throttle over idle, while in neutral, that other one will eventually sneeze, but not as often as the other one does.

Re: Muffler orientation
FWIW (which is nothing!) I could not personally deal with one side acting differently than the other side...
