Abstract
A boat propulsion apparatus is constructed such that an operation mode can be switched to a reverse mode and an amount of an output can be set by an easy operation without a complicated structure and further in which a main body of the propulsion apparatus can be locked to a hull. The boat propulsion apparatus is provided with a main body and a locking mechanism. The main body of the propulsion apparatus is provided with an electric motor, a throttle grip, a potentiometer arranged to detect an indication by the throttle grip, a first controller arranged to control an operation mode and an output of the electric motor depending on an output of the potentiometer, and second controller arranged to control the locking mechanism depending on an indication provided by the throttle grip. According to an operation for turning the throttle grip to a reverse mode area, the controller switches the electric motor to the reverse mode, and the second controller operates the locking mechanism to lock the main body of the propulsion apparatus to a hull.
