  • Patent number: 10279880
    Abstract: Disclosed is an control device of an outboard motor, including: a computation unit configured to set, as a starting point, a timing before a gearshift mechanism is shifted from forward to neutral after an accelerator opening level is fully closed in a case where an operator's manipulation is performed from forward to neutral, and compute a time-series change of an engine rotation speed as a simulated ship speed on the basis of the engine rotation speed detected by an engine rotation speed detector at the starting point; and a control unit configured to control an actuator such that, in a case where the operator's manipulation is performed from forward to reverse through neutral, the gearshift mechanism is maintained in the neutral position until the simulated ship speed estimated by the computation unit becomes a predetermined threshold value or lower, and is then shifted to reverse.
