ABSTRACT:
An engine control system for a watercraft includes a throttle valve or other engine output adjustment device. A control device controls the a state of the adjustment device (e.g., controls the position of the throttle valve). A controller is located remotely from the engine and provides the control device with an initial control amount to apply to the adjustment device. The control device determines an amount of engine load, preferably based upon signals from an adjustment device sensor (e.g., a throttle position sensor) that detects the state of the adjustment device (e.g., the position of the throttle valve) and an engine speed sensor. The control device stores a control map that has control amounts versus the initial control amounts and the engine load. The control device selects one of the control amounts using one of the initial control amounts and one of the engine loads.
