Danny, you have put it as it happened. I know that maneuvering to port side propeller is pushing towards the body of bow thruster and when maundering to starboard side propeller is pulling and all force is on nylon screws. Maybe the hub is the problem, I do not know. I need to order new propellers, hub and nylon screws. When I order a propeller Amel send hub and screws as well or I have to order that as well.
It is interesting that after I did last repair all worked well in my boat berth. After I lost first propeller I did not change hub. Maybe that was my fault.
