Abstract
An engine output control device is configured to detect an actual engine speed and to determine a modified engine speed based on the actual engine speed that is more in proportion to the speed of the watercraft than the actual engine speed. The modified engine speed can be used to control the output of the engine so as to provide a more natural feeling for the operator of the watercraft. The modified engine speed can also be used as an indication of the speed of the watercraft. As such, the modified engine speed can also be used to determine the extent to which the output of the engine can be raised to provide additional thrust for steering purposes.
