ABSTRACT:
In an outboard motor shift control system having a shift mechanism including a forward gear, a reverse gear and a clutch and an electric motor moving the clutch to engage with one of the forward and reverse gears or to disengage it therefrom, current supplied to the motor is detected, and completion of shift change is discriminated based on the detected current. With this, it becomes possible to detect completion of the shift change accurately, without being affected by shift mechanism aging and manufacturing variances.
