WTF? Can't they put a muffler system on them, or is it the blades that
make the most noise?

Trust me. The engine is loud.
The prop is much, much, louder.

Down at Wootens the make the passengers and the drivers wear ear
protection. I don't know of anyone who doesn't.
I do know a couple guys down in Everglades City who have airboats.

So, why not put a shroud round the prop, it shoudl at least silence it
some?

No ear protection offered here. The boats are load at WOT but not
deafening.

Looks like each engine goes into a dual exhaust with some big mufflers.
When I rode, we were given ear muffs. The operator was wearing them also.
