If you have a 2007 motor guide trolling motor you may want to call motor guide service dept and see if you have one with a defective part in it. I lost 1&2 speed on mine i thought it was the roller switch. wrong! MG told me that they had a new supplyer for a part in the motor and that a small amount of motors got out the door before they caught the problem of a bad soider conectiion that causes the motor to run hotand burn up the contacts.
