Hello picked up a used 1995 minkota foot control trolling motor at a rummage sale model 765 mxt 36 pounds of thrust with a 42 inch shaft. It seems to run great except. The problem i have is it runs backwards. Does anybody have any idea what would cause this? and how do i fix it? switching the leads around does not change the direction of the motor. is it possible that the wrong prop was put on? Any ideas would be greatly appreciated thank you<br />fshkpr
