ABSTRACT:
The present invention describes a system for controlling the planing angle of a boat powered by an outboard motor. Sensors are provided which measures the inclination of the propeller of the boat and the acceleration of the boat. An angle-changing motor is mounted between the outboard motor and the boat and a motor control means receives signals from the angle sensor and the acceleration sensor in order to control the angle between the propeller and the boat. Other sensors can be applied to detect the angle between the outboard motor and the boat in order to prevent excessive angles from occurring. A timer can also be used to nullify the effects of the acceleration sensor after a predetermined time.
