Bow Thruster problem
We have a Lewnar 185tt bowthruster in our Beneteau Oceanis 36cc. The thrust has suddenly become poor, is hardly able to push to either side and motor is having a " new" sound.
What I have checked so far is
1. Voltage on motor (13V when idle and 10V when running)
2. Propeller for debris ( no debris, all blades are intact and the propeller is easily turned by hand)
3. Brushes (managed to get one out of the housing. It had required length and was in ok shape)
Anybody with similar experiences and/or an idea of what can be wrong
