Minn Kota PowerDrive Prop WONT SPIN!!!

So the last time I was out fishing I ran my trolling motor into the mud. The prop would not work so I put the boat on the trailer and was done. I was upset because this was literally the 4th time using my new Minn Kota! Thankfully after doing some digging though I was able to figure out the problem and it turned into a quick fix that didn't cost me a thing!
