ELECTRONIC REMOTE CONTROL SYSTEM OF A PROPULSION SYSTEM FOR A WATERCRAFT AND A WATERCRAFT
First Claim
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.

Abstract
An engine electronic remote control system is provided that can include 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 can comprise an operating state determination subsystem, a shift actuator, a shift position detector, and a lever position detector. In an embodiment, the shift actuator can drive a shiftable component to a neutral when a main switch being switched on is switched off while the control lever is in a position other than a neutral position.
