Bow Thruster and issue with broken blade with a non-branded propeller

There could be several reasons for the propeller rubbing against the tube when bursting to Port, but remember the tolerance is very close, and bursts will cause a lateral force one way or the other...any lateral play, will temporarily relocate the propeller slightly and momentarily.
My guess in order of probability for the lateral play of the propeller:
- The pin through the hub could have worn a bigger hole in the hub
- The screws could have worked loose, or stretched
- The thruster propeller shaft bearings need replacing
And, of course, non-branded propeller may have been a little off in dimension or, flex's when lateral thrust is applied.
Good luck on your propeller replacement...service it every two years.

So Bill, I believe I know what I need to do when I haul out in 2 weeks. Wondering a) if you know of a reason why the prop is rubbing against the thruster shaft while giving port bursts? b) before I contact Maud do you know the cost of a new “Amel” thruster propeller? You did and awesome job on your last service of my thruster! She is dry as a bone and works flawlessly… obviously up until this point but I don’t consider that a bad thing considering the time between services. Also, considering 2 prop blades brought me and my family in safely, without incident while getting tossed around in 20+ knots of breeze. :) Cheers and as always thanks for your help.
