Steer-by-wire boats have no hydraulic lines or cables to tap, so an autopilot talks to the steering electronically. Compatibility is narrow, and the packs here are made for specific systems: generic drive-by-wire, Yamaha Helm Master, or SeaStar Optimus. Confirm that your steering system is on the list before ordering. None of these packs includes a drive, since the steering already has one.
