Sorry to come back with this issue. Today I lost propeller again when I was going stern to my berth in marina. All was ok when I was using bow truster to move boat to port side. When I tried to move bow of the boat to starboard I lost the bow thruster propeller agin. I am confused as this is the second time it happened. Can someone advise what I might be doing wrong?? This first time the plastic where the propeller is put in and then tied with plastic screws did not have any of leftovers of plastic screws. It is the same this time. I know I have tied it very solid.
Any ideas as this is getting very expensive exercise for me.

Thank you.
