I recently bought a Minn Kotta edge from a buddy of mine. He told me it would not turn full motion. After looking at it I found the plastic heading arrow had broken off inside. I cleaned all the plastic out and checked out the ggears, cables, and foot pedal. All look great with no noticeable issues. When I go to turn the motor will not turn all the way. I have forward but will not turn only turn about 3/4 of the way back so no backing. Anyone know what I'm missing?
