Davis Instruments Rudder Position Indicator, Wheel-Mount Gauge for Mechanical and Hydraulic Steering

The Davis Instruments Rudder Position Indicator gives helmsman instant visual reference of rudder angle, a key safety factor when moving in and out of a berth, drawing alongside another boat, picking up a skier, or mooring in tight quarters. The indicator mounts directly to the steering wheel hub, approximately 2 inches (5 cm) in diameter, using a self-adhesive pad, so it reads rudder position right at the helm where the operator is already looking. As the wheel turns, the pointer swings a full thirty degrees with each revolution, giving a clear, repeatable visual cue of how far the rudder has moved. The housing is hermetically sealed, weatherproof, and sunproof for long service life in an exposed cockpit environment. There are no cables to run, no adjustments to make, and no electrical connection required; the mechanism is gravity powered, so it works independent of the boat's electrical system and needs no maintenance once installed. It is suitable for boats with mechanical steering systems and single station hydraulic steering systems.
