ABSTRACT:
A speed control system for a small planing boat can comprise a speed sensor to detect a vessel speed of a boat body, a speed information storing unit on which data of a previously set maximum speed limit of the boat body is stored, and a speed control device for controlling the cruising speed of the boat body not to exceed the maximum speed limit based on a result of a correlation between the cruising speed and the maximum speed limit. The speed control device can comprise a revolution speed sensor, a revolution speed acquiring unit and a revolution speed control unit. The speed control device can also work in conjunction with an intake air mass amount control device which can include an electronically-controlled throttle valve, an air mass amount acquiring unit and a throttle opening degree control unit.
