that makes all the noise? Could you maybe make an effective prop that
would be less noisy?

Get a noise ordinance passed and get it enforced. That's what we did
where I lived in Florida. No airboats before or after certain hours of
the day. We also made a stink about the damned things cruising over and
cutting swaths through the wetlands.

I think they like the noise. Same sort of guys as the ones who remove
the mufflers on their motorcycles and put straight pipes on the little
Japanese cars. Big noise, small dick.

You may be right about them liking the noise. Maybe this is a techno-
opportunity to find a way around the noise generation. A little
searching shows that major noise is from the prop although many boats
have unmuffled engines too. I wonder if putting a cowling around the
prop would work, somebody must tried this.
