A control system for controlling the speed of a boat of the type including a motor having a throttle control lever coupled to a throttle of the motor provides for stable and predictable control of the speed of a boat The control system includes a position detector configured to detect the position of the throttle control lever and to generate a first signal representative of a target speed of the motor; a sensor which generates a second signal representative of the actual speed of the motor; an actuator adapted to control the throttle; and a servo controller, which in response to the first signal and the second signal, generates an output to adjust the position of the actuator.

1. A speed control system comprising: a first servo control loop to control the speed of a boat, the first servo control loop having a plurality of input signals and an output signal; a second servo control loop to control the speed of the motor, the second servo control loop having a plurality of input signals, one of which is the output signal from the first servo control loop. 2. The control system of claim 1 further comprising a third servo control loop to control the position of an actuator coupled to a throttle of the motor. 3. The speed control system of claim 1 wherein the first servo control loop processes the input signals digitally to generate the output signal.
