The SI-TEX SP-120C brings full-color autopilot capability to small vessels under 38 feet, supporting hydraulic, mechanical, and solenoid steering systems without requiring a separate junction box. A high-performance 9-axis rate gyro compass, GPS SOG/COG input integration, and a compact splash-proof color LCD head make this a capable and straightforward upgrade for 1994+ Mercury I/O and Volvo Gas inboard/outboard applications.

Features:

• Compatible with hydraulic steering, mechanical steering, and solenoid control
• No separate junction box needed — all connections route directly to the rear of the control head
• Suited for vessels under 38 feet
• Operates in Virtual Rudder Feedback mode for outboards; a separate rudder feedback unit can be added for inboard installations
• Simultaneously displays actual compass heading, selected heading, and rudder angle
• Compact 4.1" x 4.1" splash-proof control head with large, easy-to-read color LCD
• User-friendly software simplifies heading selection, operation, and setup
• 9-axis rate gyro compass delivers precise steering response
• Accepts GPS Speed Over Ground (SOG) and Course Over Ground (COG) input to improve steering performance
• NMEA-0183 GPS interface accepts input from most chartplotters for waypoint and route steering
• NMEA-0183 compass heading output at 10 kHz for MFD chart/radar overlay interface
• Steering modes: Manual (Power Steer), Auto (maintains selected magnetic course), GPS (steers to waypoint or route), and Wind (steers to wind angle when connected to a wind sensor)
• Backed by a 2-year SI-TEX warranty
