Installation of the Sensor Ball
The Sensor (Compass) Ball needs to be mounted forward of the center of your boat. Make sure you mount it away from magnetic disturbances (stereo speakers, wiper motors, anchors). You will need to calibrate your compass on the water after installation of system and before you use the autopilot.
Step one (Mounting the Sensor Ball)
Hold the mounting bracket in the desired position and drill through the holes into the mounting surface. (Be sure that the wire coming out of the ball can exit the ball straight down.) Tap if necessary. Install and tighten the three mounting screws as shown in
If you need to make a paper template for a drill pattern: The mounting holes are equally spaced on a 1.224 inch radius circle.

Step two (Placing ball in bracket)
Place the ball, wires down, into the bracket and capture it by snapping the cage over the ball, sliding the tips of the cage between the ball and the legs of the bracket. Do the two legs without the thumbscrew first. Rotate cage upwards to catch the bracket with the thumbscrew. See fig.
