The new SI-TEX SP-90 Autopilot with fixed-mount, waterproof control head is designed to fit inboard vessels 30 to 60 feet, with continuous-run hydraulic pump systems.  This newly designed autopilot is the “extra hand” on deck that boaters always need, and it keeps them right on course–effortlessly.  The operation is a snap:  Simply set the course and the SP-90 takes the controls, piloting to the next destination with ease and accuracy.
