Give a listen to the interview. These lads are in the final preparations to drive across Darwin Harbour. 30 meters down in pitch black conditions.
A failed attempt was made in 1983 which you can learn about with a Google search.🙂

Was the exhaust snorkel for environmental or other reasons? Would the water pressure have been higher than the exhaust pressure if they just vented it into the water?
A pretty good effort regardless!

Usually, the exhaust gases will force the water out of the way, which is why you basically never see an exhaust snorkel on a car that has an intake snorkel.
I think the question was more like “Would the increased water pressure at that depth put too much back pressure on the engine and prevent the exhaust coming out / force water into the engine?”
Either they were concerned about that, they didn’t want water to rush in immediately if the engine stopped, or they were just being on the safe side.
Yeah that’s what I was getting at, 30m is a long way down!
