Not that I can recall. I have spun props and sheered pins on other motors and sheered all the blades (pin failed to sheer) so I am familiar with hitting things haha but no on this.I was going to just remove to check for fishing line on the shaft and found it out. This particular prop is a SS prop that I have spun and had rebuilt so hoping that it should work as intended if I did hit something but I dont remember any events.
