Si-Tex Rudder Indicator f/Use w/SP70 80. It can save not only your gel coat but your pride. The Si-Tex SRA-1 Rudder Indicator gives you a precise look at exactly where your rudder is positioned. An easy-to-read 3-1/8" diameter analog faceplate displays in high resolution the rudder position from zero through fifty degrees to either port or starboard. High visibility white characters and scale registrations along with red and green directional markings stand out from a black background. Where many other analog rudder angle indicators have a pointer at the twelve o'clock position on the dial the Si-Tex SRA-1 Rudder Indicator has a zero position at six o'clock. This configuration has the advantage of being more intuitive. The Si-Tex SRA-1 Rudder Indicator will fit a standard 3-3/8" circular instrument cutout in a dash or it can be mounted in an optional watertight ABS plastic case.
