Abstract
A control system for a marine engine includes a control device to control the engine. A transmitter creates a command signal and sends the command signal to a receiver. The receiver receives the command signal and transfers the command signal to the control device. The control device includes memory to store the command signal. The control device determines whether the command signal is correctly transferred to the control device. The control device controls the engine in complying with the command signal transferred from the receiver when the command signal is correctly transferred. The control device controls the engine in complying with the command signal stored in the storage device when the command signal is not correctly transferred.
