Step 5: Install the Rudder Position Sensor 25

3.Drill pilot holes using a 3 mm (1/8 in) drill bit.

4.Attach the tiller pin to the tiller arm using the two self-tapping screws supplied (No 8 x 3/4 inch, countersunk) or suitable bolts, nuts and lock washers.

Attaching the connector rod

1.Use a hacksaw to cut the threaded connector rod to length.

2.Screw the lock nuts onto the rod and then the ball-pin sockets.

3.Press the sockets onto the pins on the sensor arm and tiller pin.

Note: To give the precise rudder position, the rudder sensor has a built-in spring to remove any free play in the linkage to the tiller.

Checking alignment

Move the rudder from hardover to hardover and check that at all rudder angles:

•all moving parts of the sensor remain free from any obstructions

•the sensor and connecting rod remain accurately aligned

•the ball joints do not bind
