Damaged propeller problems

It is difficult to estimate the increase, but even a small percentage of extra fuel consumption will quickly exceed the repair price of underwater propeller repair.

Several problems arise from damaged or bend propeller blades. Due to the bent section of the blade, the pitch of this blade has increased and for sure your fuel consumption will rise. Even if you don’t notice any significant vibrations, because the propeller is now running heavier.

The fact that one (1) blade has a higher pitch, results in an unevenly distributed pressure on the propeller. The shaft installation was not designed to handle this.

The engine has to work harder, which could create the risk of overloading. Due to the bent section, the water does not flow smoothly along the blade surface, so there is a chance for further damage due to cavitation.

Sometimes an indication of this phenomenon  is an increased level of propeller noise, but it is possible that you do not notice this during sailing at all, while cavitation damage still progresses.
