Abstract
A throttle valve opening control device for a watercraft engine includes a control section for controlling a valve drive section that drives the throttle valve based upon a signal from a remote controller operating position detecting means. The control section determines whether the operating position is in a trolling range or in a propelling range by the signal from the remote controller operating position detecting means. When the control section determines that the operating position is in the trolling range, the control section adjusts the throttle valve opening by an amount, relative to an operational amount of the remote controller, smaller than when the operating position is in the propelling range.
