(54) Controller for an electric outboard drive system for a watercraft


(57) The present invention relates to a controller for an electric outboard motor comprising an electric motor drive unit (6) for driving a propeller (33) which protects a control system of the electric outboard motor an is excellent in operating performance. The inventive controller for controlling the electric motor drive unit is provided with an electric motor current detection means (101) for detecting the current to the electric motor (31) of the electric outboard motor when the current is not less than specified value, electric motor stopping means (102) for stopping the electric motor (31) in an overcurrent state in which the current to the electric motor (31) is not less than a specified value, and electric motor control means (105) which performs the step of releasing the stop of the electric motor (103) by operating the accelerator from an overcurrent state to the mutual state, and stopping the electric motor (31) after driving the electric motor (31) for a specified period of time when the accelerator (105) is opened again.
