Overview

The Simrad 20193454 is a transmission link used between a rudder tiller arm and a rudder feedback sensor so rudder movement is transferred cleanly to the sensor.

It fits Simrad RF300 rudder feedback sensors and is also used with RF25N and RF40 rudder feedback units. The ball-and-socket joints at the ends let the linkage follow changing angles as the rudder moves through its full travel.

If your current linkage is bent, seized, or has play in the joints, replacing it helps keep rudder position feedback steady, which matters for predictable autopilot steering.

Key features

• Mechanical transmission link (tie rod) for Simrad rudder feedback installations
• Compatible with RF300, RF25N, and RF40 rudder feedback units
• Ball-and-socket joints accommodate angle changes through rudder movement
• Helps maintain consistent rudder position feedback when the sensor is aligned correctly
• Common service replacement when refreshing steering feedback hardware

What's included

• Transmission link (tie rod)
• Ball-and-socket fittings for the linkage ends

Compatibility and fit

This is the linkage component only. It connects the rudder tiller arm to the lever on the rudder feedback sensor, so the sensor, mounting bracket, and steering arm attachment points must already be in place and in good condition.

Before installation, confirm there is clear space for the rod to move without contacting hoses, wiring, or structure at full port and starboard travel.

Installation and setup

Attach one end to the rudder tiller arm and the other to the rudder feedback sensor lever, then adjust the linkage so the sensor sits at mid-travel with the rudder centered. Cycle the steering lock-to-lock to confirm the joints move freely and nothing binds at the ends of travel.

Once everything is secured, run the rudder feedback calibration steps in your autopilot to match the linkage geometry.

Maintenance and care

During routine washdowns, rinse the linkage area and check the joints for stiffness, corrosion, or looseness. Any free play here can show up as inconsistent rudder feedback, so it is worth including in seasonal steering inspections.

Who it suits on board

This link is a straightforward match for boats using Simrad rudder feedback based autopilots where the existing tie rod is worn or where a fresh linkage is needed as part of a feedback sensor install.
