Your Ocean Alexander yacht is equipped with a Side-Power® Joystick Control Unit (JCU), providing intuitive and precise control of the vessel’s bow and stern thruster systems. Designed for both recreational and commercial marine applications, the JCU delivers responsive maneuvering while incorporating built-in safety features, system monitoring, and diagnostic capabilities.
The JCU serves as the primary operator interface for the thruster system, allowing controlled thrust during docking, close-quarters maneuvering, and low-speed vessel handling. Depending on your vessel’s configuration, the system may support proportional or on/off thruster operation, providing smooth and predictable control while continuously monitoring system status.
This knowledge base section provides guidance on:
- System Operation – Activating the thruster system and normal joystick operation.
- Status Indicators – Understanding the JCU display, LEDs, and operator notifications.
- Error Codes & Diagnostics – Common alarms, fault indications, and recommended corrective actions.
- Troubleshooting – Initial diagnostic procedures and operational checks before requesting service.
- Manufacturer Documentation – Original operating manuals, technical specifications, and service information.
Understanding the normal operating behavior of the JCU and recognizing system indications will help ensure safe operation, reduce the likelihood of equipment misuse, and assist in quickly identifying potential issues before they become more significant.
Important: Thrusters are designed to provide short-duration maneuvering assistance and should not be operated continuously for extended periods, as prolonged use may activate thermal or overload protection. Always verify that the thruster compartment is free of obstructions before operation and ensure adequate battery voltage is available. If the JCU displays an error code or warning indication, refer to the troubleshooting section and manufacturer documentation before continuing operation. Any electrical diagnostics, software updates, or repairs should be performed only by qualified marine service personnel.
