Also, the propeller noise is heard from a lot of distance, even from outside the water. You should only hear it when you are very close to it when you are outside of the water.

Yes, this really needs to be fixed. I am currently building a superyacht and I can hear the propellers all the way from the bridge; in fact, I can hear them from 200+ meters away. I would feel very bad for the guests on this creation. I believe that if the engines/propellers are in an isolated environment then they should produce far less sounds, ex. engine being in an engine room or the propellers being under the water's surface.

Guys could you please remove the medium water propeller sounds. They are EXTREMELY annoying while playing for few hours. This is an easy fix ,,,just remove these until they are fixed. They are driving everyone nuts. I do have a boat and no way you can hear the propeller sound when the engine is running.

I agree. Ship propellers volume level is way to high compared to other sounds. When my engine revs on low RPS the only thing I can hear are the propellers.
