The compressor intakes were stub tubes that extended up under the shroud. The flagpole was a tube within a tube. The inner tube was the exhaust, which exercises out the top. The outer tube was a "shroud", open at the top and bottom. The carb intake was attached with a rubber hose to the side of this shroud, which would scavenge any possible exhaust leak.
Aquanaut – exhaust exits high, fresh air to diver enters low.
Brownie- exhaust exits low, fresh air enters top of flagstaff to diver. (High)
I think CO is heavier than air, thus the possible problem, especially in a restricted air space, such as the cockpit deck of a sportfisherman on a calm, no breeze day.
Neither unit required cooling water, so they didn’t "have to" be used while floating.
