SI-TEX SP-120 System w/Rudder Feedback & Remote Mechanical Drive - 1983-93 Mercury IO/Volvo Diesel

The SI-TEX SP-120 System with Rudder Feedback and Remote Mechanical Drive is a precision autopilot and steering solution designed specifically for Mercury inboard/outboard and Volvo Diesel marine engines manufactured between 1983 and 1993. This system is ideal for serious boaters who seek reliable, hands-free directional control in a variety of water conditions, effectively reducing the fatigue associated with manual steering during extended trips.

Equipped with integrated rudder feedback technology, the SP-120 continuously monitors hull response and steering angle, enabling real-time course corrections for stable and predictable navigation even in challenging conditions. The remote mechanical drive mechanism allows for seamless integration with existing steering hardware, preserving the original helm geometry while enhancing precision with electronic controls. Built to withstand the rigors of marine environments, this system is designed to endure salt spray, vibration, and thermal cycling.

Boaters utilizing 1983–1993 Mercury IO and Volvo Diesel powerplants will find the SP-120 particularly beneficial for navigating coastal waterways, managing trolling patterns, or maintaining course in open water. Its compact design ensures it fits neatly on most modern helm console layouts, making it a versatile addition to any boat.
