Abstract:
1. An electronic remote control system of an internal combustion engine for a watercraft including an engine electronic control unit for controlling an operating state of the engine and a remote controller having a control lever capable of transmitting a control signal to the engine electronic control unit to achieve a target operating state, the system comprising: an operating state determination subsystem that is capable of determining whether the engine is in an operating state; a shift actuator capable of driving a shifting component according to a target shift position set with the control lever; a shift position detector for detecting whether the shifting component is in neutral; and a lever position detector for detecting whether the control lever is in a neutral position, and wherein the shift actuator drives the shifting component to neutral when a main switch that was previously switched on is switched off while the control lever is in a position other than the neutral position and wherein the shift actuator maintains the shifting component in neutral when an engine rotational speed is lower than a predefined rotational speed after the main switch that was previously switched on is switched off while the control lever is in a position other than the neutral position.
