After almost a year of use we replace the prop and the lower skeg on our Power Pole Move PV trolling motor. You can see the damage we've accumulated during approximately 400 hours of use in extremely shallow salt water. I think the ability to replace these plastic parts and save the powder coating on the motor body is a great feature of this new TM.
