Ecotech Marine MP40w ES operating noise

[stellarfly]

Hey guys,

I just love the look and simplicity and performance of the MP40's. Judging by what I have heard and seen they are awesome. But what about operating noise that the motors make when they are in operation and fully balanced and the such. Are they noisy? I have seen some videos on youtube with some people complaining that their spouses are just not happy. What are peoples thoughts on this? is that one of their drawbacks??

let me know.
