Hi all,  
One of my vertical trusters stopped working today. It tries to rotate, but stops and start in small spurts. I removed propeller and everything is clean. when you rotate by hand you can feel as if something is catching. I disassembled motor by removing collars, everything is clean?  
As mentioned it tries to turn?

hey @spudder

I had almost the same problem, Did you remove the magnetic coupling to check it inside? something could be stuck inside or the coupling could be corroded.

I changed out the T200 Thruster.  
Alls good know.  
Still would like to know why the thruster packed it in as there wasn’t much dive time on it?
