ABSTRACT:
Steering mechanism for a boat motor having a shaft which turns to turn the boat motor. A plurality of first contacts is spaced circumferentially around the shaft. A sweep contact mounted on the shaft sequentially engages the first contacts as the shaft turns. A pivotally mounted pedal swings a contact plate. A plurality of second contacts, each of which is connected to a respective one of the first contacts, is engageable with the contact plate. Upon movement of the pedal power is supplied to the steering motor until the sweep contact engages one of the first contacts which is connected to a second contact that is free of the contact plate. The contact plate can include two contact plate portions, one of which is connected in series with the steering motor when the pedal is moved in one direction and the other of which is connected in series with the steering motor when the pedal is moved in an opposite direction. Polarity of the connection to the steering motor is reversed as the connection with contact plate portions is changed to reverse the direction of steering motor advance.
