2

Place the sensor in the chosen mounting location, and mark 

the center of the three mounting holes.

3

Place the tiller-arm mount on the tiller arm in the chosen 

location, and mark the center of the two mounting holes.

4

Using a

 in. (3.2 mm) bit, drill three pilot holes on the 

mounting surface for the sensor, and two pilot holes on the 

tiller arm for the tiller-arm mount.

5

Fasten one of the ball-joint assemblies to the tiller-arm 

mount, using the included M6 locknut.

6

Place the other ball-joint assembly into the appropriate hole 

on the sensor (typically the second hole from the tip), and 

fasten it with the included washer and locknut, using a 10 

mm socket.

7

Tighten the ball-joint assemblies using a 8 mm wrench at the 

base.

8

Fasten the sensor to the mounting surface using the included 

screws.

9

With the rudder amidships and the sensor at center position, 

measure the distance from the ball-joint assembly on the 

sensor to the location where you plan to attach the tiller-arm 

mount to the tiller arm.

10

If the threaded rod is too long, you must cut it to the correct 

length (

page 3

).

11

Thread both of the standard M6 nuts onto the threaded rod.

12

Thread the rod into the ball-joint assembly connected to the 

sensor.

13

Thread the other end of the rod into the ball-joint assembly 

connected to the tiller-arm mount.

14

Fasten the tiller-arm mount to the tiller using the included 

screws.

15

Tighten the M6 nuts on the threaded rod against both of the 

ball-joint assemblies.

Cutting the Threaded Rod

If the included threaded rod is too long for your chosen 

installation location, you must cut it.

1

Thread one of the included standard M6 nuts onto the 

threaded rod.
Do not use one of the included M6 locknuts.

2

Measure and mark the threaded rod with electrical tape.

3

Using the appropriate saw, cut the threaded rod at the 

marked location.

4

Remove the nut from the threaded rod, turning it counter-

clockwise over the cut area.
The nut should straighten any threads that may have been 

damaged while cutting the rod.

Connecting the Device to the Autopilot System

1

Route the cable from the sensor to the orange 12-pin 

connector on the ECU of the autopilot system.
The installation instructions provided with your autopilot 

system will help you identify where this connector is located.
If needed, extension cables are available.

2

Connect the sensor to the autopilot system.

Configuring the Sensor

When connected to a  Garmin autopilot system, the sensor 
is configured using the autopilot helm control.

NOTE: 

If an error appears during these steps, the sensor may 

have reached the limit of its movement range. Make sure the 

sensor was installed correctly. If the problem persists, bypass 

this error by moving the rudder to the farthest position that does 

not report an error.

1

Enter Dealer Mode by following the procedures in your 

autopilot installation instructions.

Position the rudder so that the boat would steer fully 

starboard, and select 

OK

.

4

After the starboard calibration is complete, position the 

rudder so that the boat would steer fully port, and select 

OK

.

5

After the port calibration is complete, center the rudder 

position, let go, and select 

Begin

.

The autopilot takes control of the rudder.

6

Wait while the autopilot calibrates the rudder.

7

Select an option:
• If the calibration completes successfully, select 

OK

.

• If the calibration did not complete successfully, repeat 

steps 2–6.
