Sitex Sp110 Auto Pilot Rudder Feedback Type S Drive



Designed for small boats, the SI-TEX SP-110 autopilot brings all the features of more expensive models into a single compact unit, without the need for a separate junction box. Suitable for small motorboats as well as sailing yachts up to around 15 meters.

Designed to an industry standard 110mm square casing it fits nicely together with other instruments. SI-TEX has developed the SP-110 to provide performance and reliability for the small boat user. There are simply no other autopilots on the market so compact and easy to install with the same level of functionality.

The SP-110 can operate as a stand-alone system with the control unit and compass connected to either reversing pumps or mechanical drive units. Alternatively, the system can be integrated via NMEA-0183 interface with navigational aids such as a GPS or GPS plotters to provide waypoint steering. The SP-110 also features a Wind steering Mode that enables the unit to steer to wind when interfaced via NMEA-0183 to a Wind Sensor.

The Straight shaft drive unit replaces the manual drive used on cable steered boats and is mounted directly behind the dash. The drive is directly compatible with the Morse 290 steering helm but comes with its own bezel kit and can be retrofitted in most installations using the cable and steering wheel from the manual steering helm on the boat.  Additional items my be required to adapt to your sterring system.
