1. Product Overview
The ELING Waterproof Boat Rudder Angle Indicator Gauge is designed to provide precise rudder position feedback for marine applications. This gauge features a 0-190ohm signal input, a 2-inch (52mm) diameter, and a red backlight for clear visibility in various lighting conditions. It is built with 100% waterproof and anti-fogging protection, ensuring reliable performance in harsh marine environments. This manual provides detailed instructions for installation, operation, and maintenance.

2. Setup and Installation
Proper installation is crucial for the accurate and reliable operation of your rudder angle indicator gauge. Follow these steps carefully:
2.1 Preparing the Mounting Location
- Select a suitable location: Choose a flat surface on your dashboard or panel where the gauge will be easily visible and accessible.
- Cut the mounting hole: Open a 2-inch (52mm) diameter hole. Ensure there is a depth of at least 2-3/4 inches (70mm) behind the panel for the gauge body and wiring.
Figure 2: Installation diagram illustrating the required hole dimensions (52mm diameter, 70mm depth) and the process of inserting and securing the gauge.
2.2 Installing the Gauge
- Insert the gauge: Carefully insert the gauge into the prepared 2-inch (52mm) diameter hole.
- Secure the gauge: Use the provided M4 nuts and C-type bracket to fasten the gauge securely to the panel.

2.3 Wiring Connections
The gauge requires a 9-32VDC power supply. Connect the wires as follows:
- Blue Wire: Power Negative (-)
- Red Wire: Power Positive (+)
- Black Wire: Signal Wire (connects to the rudder sensor)
- Orange Wire: Backlight Power Positive (+)
The output signal from the rudder sensor should be 0-190ohm. If you need a compatible rudder sensor, please refer to ASIN B07V4PTW89.

3. Operating Instructions
Once installed and wired correctly, the ELING Rudder Angle Indicator Gauge operates automatically. The needle on the gauge will display the current angle of your boat's rudder, indicating its position between "PORT" (left) and "STBD" (right).
- Power On: When the boat's electrical system is powered on, the gauge will activate.
- Rudder Movement: As the rudder moves, the gauge needle will respond in real-time, providing an accurate visual representation of the rudder's angle.
- Backlight: The red backlight will illuminate when the orange wire is connected to a positive power source, enhancing visibility in low-light conditions.

4. Maintenance
The ELING Rudder Angle Indicator Gauge is designed for durability and requires minimal maintenance. However, regular checks can ensure its longevity and continued accuracy:
- Cleaning: Wipe the gauge face with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the display or housing.
- Wiring Inspection: Periodically check all wiring connections for corrosion or looseness. Ensure connections remain secure and free from moisture.
- Waterproof Integrity: While the gauge is 100% waterproof, ensure the mounting area remains sealed to prevent water ingress behind the panel.
- Sensor Check: If you experience inconsistent readings, inspect the rudder angle sensor (sold separately) and its connections for any issues.
5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Gauge not powering on / No backlight | No power supply; Loose wiring connections; Blown fuse. | Check power source (9-32VDC). Verify all wire connections (Blue, Red, Orange). Inspect fuse in the power line. |
| Inaccurate or erratic readings | Faulty rudder sensor; Loose signal wire connection; Incorrect sensor resistance (not 0-190ohm). | Ensure the rudder sensor is functioning correctly. Check the black signal wire connection. Confirm sensor output is 0-190ohm. |
| Gauge fogging up | Extreme temperature changes; Seal integrity compromised. | The gauge is anti-fogging. If fogging persists, ensure proper ventilation behind the panel and check for any damage to the gauge's seals. |
