If you need to know for sure, Send it to Materials Technology in Totton.
They can have a proper look at it.

Fast fracture - probably caused by the rope.
Fatigue failure - possibly initiated by out of balance / damaged propeller over time.
Friction weld failure - maybe down to manufacturing defect.

From my perspective the rusty middle part had been severed before this event. Maybe this is not the first prop strike, or maybe it is just a failure of the metal? Doesn't really matter it just needs a new shaft installed. To a pro it shouldn't be too bad of a job, unless there is a lot of corrosion in which case it could get ugly.

Is that 'old' corrosion in the centre, or corrosion that occurred between the time the shaft broke and the picture was take?
