ABSTRACT OF DISCLOSURE Disclosed herein is an outboard motor having a control circuit for a permanent magent, direct current motor, which circuit comprises a source of direct current, a permanent magnet motor including an armature winding having opposed terminals, control means including a first resistor connected between one of the armature winding terminals and the direct current source, a second resistor connected to the one armature winding terminal, a shunt lead connected to the one armature winding terminal, and a speed control switch connected to the direct current source and selectively operable between a first position connecting the direct current source to the shunt lead in parallel with the first resistor and disconnected from the second resistor, a second position connecting the direct current source to the second resistor in parallel with the first resistor and disconnected from the shunt lead, and a third position disconnected from both of the shunt lead and the second resistor, whereby current flow from the current source to the armature winding is solely through the first resistor, and a thermal cut-out switch connected between the one armature winding terminal and the first and second resistors.
