Rudder Position Sensor - Quadrant Close Up

In this picture you can see the rudder quadrant and the Starboard shim I made to attach the rudder position sensor arm to. Starboard is a high modulus engineered plastic sheet product available in thicknesses to 3/4 inch. Starboard is impervious to moisture and rot and is very well suited for use on a boat that is why I chose to use it. It works, cuts and taps similarly to wood and is a tremendously useful but expensive product.

On many Edson steering quadrants there are two 5/16 threaded holes already drilled and tapped into its surface. I simply measured the center to center of these 5/16 threaded holes and transferred the measurements to the Starboard shim using a set of calipers. I then drilled the two holes and mounted the ball (the arm has a socket and the base is a ball) to the Starboard perfectly centered between the two 5/16 holes. With the ball finally mounted, and screwed into the Starboard shim, I then bolted the shim to the quadrant. In the picture you can see the two 5/16 bolt heads with the ball mount for the sensor in between them.

Did you have any problems with the clearance between the rudder reference and the hot water tank? It looks close when the quadrant would turn fully.
