Sorry to hear about your experience with your Minkota power drive trolling motor.
In the winter of 2003 when I got my boat I had a Minkota 12 volt power drive on it and did not like it from the git go. I didn't like having to first look a which direction the arrow was pointing to see which way to move it. I had previously learned on a cable steer and one didn't have to look to see which direction to turn it you could tell just by the position of the pedal. Also I realized that I wouldn't be able to easily and efficiently use that foot control in the winter time with my heavy pac boots on. I didn't like the sound of the electric motor as it changed directions and discovered the 12 volt wasn't going to be enough to handle the aluminum sails on my deep v boat in the wind. I changed it out for a 24 volt Minkota Maxxum with cable steer and have continually considered it the cat's meow.
One time I smacked the dickens out of it on something and bent/cracked the shaft on it. Jerry's Trolling Motor Repair said they could cut a couple inches off the shaft and reuse it if I thought the remaining length would be long enough and save ordering a new 62 inch shaft to repair it which is what was done. I also did have to take it in one time when something electrical fried in the foot control.
After my seven years of use of my Minkota I will definitely be going back with Minkota should I need another.
