I recently bought a used 12' jon boat which came with a 1999 Minn Kota 765MXT trolling motor. The foot pedal starts the motor but it doesn't turn it. Before taking it apart, can someone please guide me thru the process and what to look for in repairing it. I saw a new pedal on Ebay but would like to try and fix what i have. The boat has a current registration so i assume it has been run within the past year.
