The SeaStar (now Dometic) Optimus Joystick, when part of a quad-engine system, provides intuitive 360-degree maneuvering by integrating with the boat’s Electronic Power Steering (EPS) and Electronic Shift and Throttle (EST) systems.
Functionality: Provides intuitive joystick control for low-speed maneuvering, including moving forward, backward, sideways, diagonally, and rotation on the boat’s axis.
Engine Compatibility: Designed for powerboats with quad (four) engines that have electronic shift and throttle (EST) controls (compatible with major brands like Yamaha, Mercury, Suzuki, Honda, BRP).
Integration: Built upon the existing Optimus Electronic Power Steering (EPS) system, sharing components like the electronic helm, SmartCylinders, hydraulic steering pumps, Pump Control Module (PCM), and CANtrak display.
Redundancy: Features dual independent sensors and circuits, dual CAN bus outputs, and redundant power supplies for reliable operation and safety.
Autopilot: Autopilot ready; compatible with third-party systems from Garmin, Simrad, and Raymarine without needing an additional autopilot pump or rudder feedback unit (RFU).
Safety & Compliance: Meets or exceeds ABYC, ISO, SAE electrical and environmental requirements, and is CE certified.

Key System Components (for Quad Engine configuration)
The full system requires several integrated components beyond just the joystick controller unit:
Optimus Electronic Helm: Electronically controls steering and adjusts wheel resistance based on speed (no oil at the helm).
Optimus SmartCylinders: Hydraulic steering cylinders with integrated position sensors (RFU).
Optimus Hydraulic Steering Pumps: On-demand pumps that supply fluid to the cylinders, minimizing power consumption.
Optimus Pump Control Module (PCM): The central “brain” that monitors sensors and controls steering.
CANtrak Display: A color digital display for setup, system status monitoring, real-time data (RPMs, gear selection), and alarm information.
Gateway: Required to interface with the engine manufacturer’s specific electronic shift and throttle system.
Wiring Harnesses: A comprehensive set of sealed, locking CANbus network harnesses connecting all components.
The OEM-Yamaha 6X6-c single-engine digital control (DEC) is a fly-by-wire remote control system that works with compatible Yamaha DEC motors, offering a streamlined installation with effortless throttle and shift control. Key specifications include its part numbers (such as 6X6-48205-73-00), compatibility with DEC engines, and features like plug-and-play dual station setup and an included ECU for each outboard
