SI-TEX SP-120 Color System w/Virtual Feedback & 9CI Pump
Eliminating external rudder sensor linkages on transom setups, the SI-TEX SP-120 hydraulic autopilot routes a 1.0 L/min reversing pump across 9-cubic-inch cylinders, using a 9-axis compass and virtual feedback to hold true headings at 12V or 24V.
- 1.0 L/min pump actuates 9CI steering cylinders
- Virtual Rudder Feedback eliminates mechanical linkages
- 9-axis compass prevents heading calibration drift
- Operates smoothly across 12V-24V DC networks

Description
Hydraulic pump hardware is not required for the Raymarine EV-DBW Evolution Autopilot, which controls compatible drive-by-wire steering systems through a digital interface. The package includes an EV-2 nine-axis sensor, p70Rs color display, and SeaTalkng cable kit. NMEA 2000 and SeaTalkng provide the listed network connection, while Volvo, Yamaha, and ZF systems are identified as compatible drive-by-wire platforms.
The system operates on 12V or 24V SeaTalkng power and supports automatic commissioning, Evolution AI technology, and virtual rudder feedback through the CAN bus. Verify the digital steering system, sensor arrangement, display location, and cable routing before installation.
Key Specifications of the Raymarine EV-DBW Evolution Autopilot
- Digital steer-by-wire interface controls compatible systems.
- Hydraulic pump is not required for this configuration.
- EV-2 provides nine-axis solid-state sensing.
- p70Rs provides the color control display.
- Volvo, Yamaha, and ZF systems are listed.
- SeaTalkng and NMEA 2000 networking are supported.
- Virtual rudder feedback uses the CAN bus.
- Automatic commissioning is specified.
- SmartController support is available as an option.
- EV-2, p70Rs, and cable kit are included.
Pump Function, Flow, and Controls
The EV-DBW system uses digital steering commands instead of a hydraulic pump for the listed drive-by-wire application. The EV-2 provides heading information, while the p70Rs manages autopilot control. Pump flow, pressure, self-priming, dry-run operation, and duty-cycle specifications do not apply to this configuration.
Plumbing, Power, and Compatibility Considerations
Verify the Volvo, Yamaha, or ZF drive-by-wire system, SeaTalkng network, 12V or 24V supply, EV-2 sensor, p70Rs display, virtual rudder feedback, and optional SmartController before installation.
Mounting, Installation, and Environmental Conditions
Confirm the 110 by 115mm control-head dimensions, flush or surface mounting, sensor position, cable routing, network connections, operating temperature, and IPX6 or IPX7 ratings before installation.
Warranty and Support
Warranty coverage is not confirmed in the available product data. Buyers should verify current coverage, exclusions, and claim procedures with the seller or manufacturer before purchase. These terms reflect currently available manufacturer information, and buyers should verify active warranty policies directly with the seller or manufacturer before purchase.
Before Ordering the Raymarine EV-DBW Evolution Autopilot
Verify the drive-by-wire system, Volvo, Yamaha, or ZF compatibility, EV-2 sensor, p70Rs display, SeaTalkng network, power supply, SmartController option, mounting location, and package contents before ordering.
