Overview / What Is Sitex SP120 Autopilot Rudder Feedback No Drive
The Sitex SP120 Autopilot Rudder Feedback No Drive system is an advanced autopilot unit that uses direct rudder angle feedback sensors, eliminating the need for additional drive motors. Instead of applying force directly to the steering mechanism, it monitors rudder position and commands your hydraulic or mechanical steering to adjust accordingly. This approach reduces wear on mechanical parts and simplifies installation.
Designed for 12V marine systems and tested in tough offshore environments, the Sitex SP120 Autopilot Rudder Feedback No Drive setup is compact yet powerful. It connects easily to existing hydraulic steering lines or mechanical steering feedback loops and interfaces via NMEA 0183/2000 to GPS and chartplotter systems. Its smart algorithm adapts over time to vessel dynamics, improving accuracy with usage.
How Sitex SP120 Autopilot Rudder Feedback No Drive Works
The system reads precise rudder angle feedback and cross-verifies with heading data to determine steering corrections. With no mechanical drive, it relies on your existing helm hydraulics or servo systems to execute the changes. This results in minimal installation footprint and fewer points of failure.
Its control unit houses firmware that processes incoming rudder sensor data in real-time, sending commands to the autopilot marine engine controls. The focus on rudder feedback ensures that steering is always based on actual rudder position, not inferred direction — improving reliability in demanding conditions.

Troubleshooting Common Issues
Explore Sitex SP120 Autopilot Rudder Feedback No Drive troubleshooting tips to resolve common installation and operation issues:
If the autopilot steers erratically, first verify that the rudder feedback sensor is correctly calibrated and reads true center. Loose wiring or misaligned sensor hardware can create false readings.
If course holding drifts over time, confirm the NMEA connection between your GPS/chartplotter and the control unit is stable. Firmware updates sometimes address minor connectivity bugs.
Cost and Durability Considerations
Discussing Sitex SP120 Autopilot Rudder Feedback No Drive cost and durability, the system is competitively priced in the mid-to-premium autopilot range. By eliminating a physical drive unit, installation costs drop, and long-term service requirements are lower.
Durability is strong thanks to marine-grade materials, sealed electronics, and a minimalist hardware footprint. Many customers report reliable performance across multiple seasons, with little maintenance beyond routine sensor checks and firmware updates.
Detailed FAQ Section
How accurate is the Sitex SP120 Autopilot Rudder Feedback system?
The accuracy of the Sitex SP120 Autopilot Rudder Feedback No Drive system stems from its direct rudder angle measurement. By relying on real-time feedback from the rudder shaft, the system calculates steering corrections based on actual physical position rather than estimated heading changes. This usually results in tighter course holding and reduced drift. Accuracy can reach within a few degrees of true heading, depending on installation quality and calibration precision.
Accuracy also improves over time, as the adaptive algorithm ‘learns’ vessel-specific steering dynamics. Many mariners experience smoother steering after several hours of operation, as the autopilot fine-tunes its control response. Regular recalibration and firmware updates can further enhance performance. However, a poorly aligned sensor or loose wiring may introduce erratic behavior, so quality installation is critical.
Can I install the Sitex SP120 Autopilot Rudder Feedback No Drive system on a sailboat?
Yes, the Sitex SP120 Autopilot Rudder Feedback No Drive system is well suited for sailboats, including both small keelboats and large cruising yachts. Because it doesn’t rely on a drive motor, it avoids adding weight and complexity—ideal for sailboat rigging and space-constrained helms. The rudder feedback sensor mounts easily on most rudder shafts used in sailboat steering systems.
Sailboat owners appreciate the quiet operation and minimal maintenance. Its hydraulic or mechanical feedback design integrates cleanly with existing steering systems; power draw is minimal even when running continuously. This makes it perfect for long-duration passages where efficiency and reliability matter most.
What are the best Sitex SP120 Autopilot Rudder Feedback No Drive options?
There aren’t multiple hardware variants—this model is designed to fit a wide range of marine steering setups. However, accessory options include extension cables, upgraded waterproof connectors, and enhanced battery protection modules. These additions improve installation flexibility and environmental resilience.
Choosing high-quality cables and connectors can decrease installation time and enhance waterproof integrity. Some dealers offer installation kits tuned to specific vessel types—ask about accessories that match your boat’s steering configuration and power system. That ensures you get the best Sitex SP120 Autopilot Rudder Feedback No Drive options for your needs.
How to repair or troubleshoot sensor errors on the Sitex SP120 Autopilot?
If you encounter sensor-related errors, begin by inspecting the physical alignment of the rudder feedback sensor. Mechanical wear or slight shifting over time may misalign the sensor, causing false readings. Tighten mounting hardware and ensure the sensor’s magnetic or optical reader aligns correctly with the rudder shaft.
Next, check the wiring harness for continuity and corrosion. Replace any degraded connectors and reseal with marine-grade heat-shrink tubing. Use diagnostic mode in the control unit to view raw feedback readings—this helps isolate whether the issue is mechanical or electrical.
If the unit still misbehaves, consider reloading firmware or reaching out to Sitex technical support for guidance. A consistent feedback error may indicate a sensor replacement is necessary—commonly a simple swap rather than full system replacement.
What maintenance steps should I follow regularly for this system?
Regular maintenance of the Sitex SP120 Autopilot Rudder Feedback No Drive system should include these actions:
- Seasonal sensor alignment and inspection.
- Firmware updates via manufacturer’s interface.
- Connector cleaning and corrosion prevention.
- Diagnostics check using onboard software to verify feedback accuracy.
A complete maintenance log should document usage hours and calibration history. This not only helps with troubleshooting but also extends system lifespan. Routine care like this ensures your autopilot remains precise and dependable across many marine seasons.
