The SI-TEX SP-80 is a fixed-mount autopilot system built for inboard, outboard, and sterndrive vessels running hydraulic or quadrant steering. This package includes the hydraulic pump and rotary feedback unit, giving you the core hardware needed for a complete installation. Once underway, set your course and the SP-80 handles the helm — freeing you to tend gear, monitor the chart, or simply enjoy the ride. Ghost Rudder backup, automatic sea state compensation, and a ten-level backlit display make this a capable and reliable choice for coastal and offshore use.
