SI-TEX SP-120 Color System w/Rudder Feedback & Type "S" Mechanical Dash Drive

The SI-TEX SP-120 Color System with Rudder Feedback and Type "S" Mechanical Dash Drive is a compact autopilot purpose-built for vessels under 38 feet running hydraulic, mechanical, or solenoid steering systems. This integrated autopilot eliminates the need for a separate junction box—all connections route directly to the rear of the control head—making installation straightforward on fishing boats, cruisers, and workboats where space and simplicity matter.

The SP-120C operates in Virtual Rudder feedback mode and delivers real-time rudder position monitoring, critical for maintaining course accuracy in varying sea conditions. The Type "S" mechanical dash drive provides tactile, reliable control independent of electronics, a practical redundancy for captains running offshore or in remote waters where electronics failure cannot be an option. The color display offers clear readout in bright sunlight and provides intuitive navigation of autopilot functions and heading adjustments. Weighing 20 pounds with compact dimensions of 13 x 13 x 16 inches, the unit integrates easily into cramped pilothouse layouts without consuming valuable console real estate.

This autopilot suits weekend anglers targeting nearshore species and commercial operators running charter or utility vessels who need dependable hands-free steering across multi-hour transits. The SI-TEX SP-120 handles the workload on small boats where larger systems prove overkill, delivering the precision required to maintain productive fishing grounds or consistent approach angles during docking. Rudder feedback capability reduces autopilot hunt and improves fuel efficiency by minimizing unnecessary steering corrections—measurable savings on extended runs. The mechanical backup ensures operation continues even if electrical systems degrade, a practical consideration for serious boaters who operate in conditions where failure tolerance is minimal.
