Marine Rudder Angle Indicator Gauge & Sensor — IP67, 316 SS Bezel, 9–32V for Yachts, Speedboats & Fishing Boats
Steering a vessel without knowing your rudder position means relying on feel and guesswork — acceptable in calm conditions, but a real liability when docking in crosswinds or navigating a narrow channel. For yacht owners, speedboat operators, and fishing boat captains who need a reliable, waterproof marine rudder angle indicator gauge at the helm, this instrument delivers a clear PORT-to-STBD readout with a cross-coil pointer drive, IP67 protection, and a 316 stainless steel bezel that holds up to saltwater spray and UV exposure season after season.
Each variant is sold as one unit or one matched set as described. The gauge bezel is manufactured from 316 stainless steel (SUS316) with an anti-fog curved glass lens. The display face diameter is 70mm (2-3/4"), with a standard panel cutout of 52–53mm (2") or 85mm for large variants. The gauge body fits panel thicknesses from 2mm to 20mm (1/12"–4/5"), secured with an M4 nut. Operating voltage is 9–32V DC (compatible with 12V and 24V systems). The standard backlight is red; custom colors are available on request. Input signal is resistive. Protection rating is IP67. Wiring: orange (backlight), red (+9–32V), blue (battery negative), black (sensor signal). Eight variants cover gauge-only, gauge-with-sensor, and sensor-only configurations in standard (52mm) and large (85mm) sizes, including KUS-branded color displays and single or dual-station sensors.
This gauge is well suited for replacing a failed or inaccurate rudder angle display on a sailing yacht or motorboat helm panel, building a new instrument cluster on a custom fishing boat or commercial vessel, and adding a second helm station display using the dual-station sensor on a flybridge or pilothouse — anywhere a durable, IP67-rated marine rudder angle indicator needs to read accurately in all conditions.
⚓
Operating voltage: 9–32V DC (12V & 24V compatible). Panel cutout: 52–53mm (2") standard or 85mm large. Panel thickness: 2–20mm. Input: resistive sensor signal. IP67 rated. Suitable for yachts, speedboats, fishing boats, and commercial vessels.
✅ Key Features of These Marine Rudder Angle Indicator Gauges
-
🧲IP67 Waterproof Rating — Dust-tight and protected against temporary immersion, making this marine rudder angle indicator gauge suitable for exposed helm stations on yachts, speedboats, and fishing boats subject to spray and rain.
-
🔩316 Stainless Steel Bezel with Anti-Fog Lens — The SUS316 front bezel resists chloride corrosion and surface pitting in saltwater environments. The curved anti-fog glass lens maintains readability in humid and cold conditions at the helm.
-
⚡Wide Voltage Range: 9–32V DC — Compatible with both 12V and 24V vessel electrical systems without a converter, covering the full range of recreational yachts, speedboats, and commercial fishing vessels in a single instrument.
-
🧭Cross-Coil Pointer Drive — The cross-coil mechanism drives the needle with consistent accuracy and strong vibration resistance — important for vessels operating in rough water where instrument vibration can cause conventional pointer mechanisms to drift or stick.
-
📦Gauge Only, With Sensor, or Sensor Alone — Buy a complete gauge-and-sensor set for a new installation, a gauge only if you have an existing compatible sensor, or a sensor alone for replacement or dual-station setups — all matched to the same resistive signal standard.
-
💡Red Backlight, Custom Colors Available — The standard red backlight preserves night vision at the helm — the conventional choice for marine instrument panels. Custom backlight colors are available on request for vessels with specific panel lighting schemes.

⚠️
Confirm your panel cutout size (52mm or 85mm) and panel thickness (2–20mm) before ordering. If you already have a compatible resistive sensor installed, select the gauge-only variant. For new installations, the gauge-with-sensor set is the recommended choice.
❓ Frequently Asked Questions
What panel hole size do I need to install this gauge?
Standard variants require a panel cutout of 52–53mm (2") in diameter. The large KUS and large color variants require an 85mm cutout. The gauge body fits panels from 2mm to 20mm (approximately 1/12" to 4/5") thick, secured with an M4 nut from behind. Measure your panel thickness and existing cutout before selecting a variant.
What is the difference between the gauge-only and gauge-with-sensor variants?
Gauge-only variants include the display unit without a rudder angle sensor — suitable if you already have a compatible resistive sensor installed on your vessel. Gauge-with-sensor variants include both the display and a matched rudder angle sensor, providing a complete system for new installations. Sensors are also available separately for replacement or dual-station setups.
What voltage does this gauge operate on?
The gauge operates on a wide input voltage range of 9–32V DC, making it compatible with both 12V and 24V vessel electrical systems. Connect the red wire to the positive supply (+9–32V), the blue wire to battery negative, the orange wire to the backlight switch, and the black wire to the sensor signal output.
Is this gauge waterproof and suitable for outdoor marine use?
Yes. The gauge carries an IP67 rating, meaning it is dust-tight and protected against temporary immersion in water up to 1 meter for 30 minutes. The front bezel is manufactured from 316 stainless steel with an anti-fog curved glass lens, making it suitable for exposed helm stations on yachts, speedboats, and fishing boats.
What type of sensor signal does this gauge accept?
This gauge accepts a resistive sensor signal via the black wire. It is designed to work with the matched rudder angle sensors available in this listing. If you plan to use a third-party sensor, confirm that its output resistance range is compatible with this gauge before purchasing.
What does the dual-station sensor option mean?
The dual-station rudder angle sensor is designed to feed two separate gauge displays simultaneously — for example, a helm station and a flybridge station on the same vessel. The single-station sensor drives one gauge. If your vessel has multiple helm positions that need to display rudder angle, select the dual-station sensor.
What does the backlight color look like, and can it be changed?
The standard backlight is red, which is the conventional color for marine instrument panels as it preserves night vision. Custom backlight colors are available — contact us before ordering if you require a different color. The backlight is controlled via the orange wire connected to a separate switch.
🛒 Select your kit set above, then add to cart — each option is sold as one gauge, one gauge-and-sensor set, or one sensor as described.
