Setup and Installation

Proper installation is crucial for accurate operation and longevity of your fuel gauge. This gauge is designed for universal fit in many marine applications.

Installation Steps:

1. Preparation: Ensure the vessel's power is disconnected before beginning installation. Gather necessary tools, including screwdrivers, wire strippers, and crimpers.
2. Remove Old Gauge (if applicable): If replacing an existing gauge, carefully remove the bracket from behind the dashboard and pull the old gauge out. Disconnect all wires. It is highly recommended to take a picture or make a diagram of the existing wiring before disconnecting to ensure correct re-connection.
3. Wiring Connections: Connect the appropriate wires to the terminals on the back of the new Sierra fuel gauge. Typical connections include power (ignition), ground, and sender unit wire from the fuel tank. Refer to your vessel's wiring diagram for specific connections.
4. Mounting: Insert the new gauge into the dashboard opening. Secure it with the provided mounting bracket and hardware from behind the dash. Ensure the gauge is firmly seated and aligned.
5. Power Restoration and Testing: Reconnect the vessel's power. Turn on the ignition and observe the fuel gauge. It should indicate the current fuel level.

Important Note for Newer Engines: Some modern marine engines, particularly newer Mercury models, may use a digital sender unit for fuel level. This analog gauge requires an analog signal. If your engine has a digital sender, a digital-to-analog converter (e.g., Mercury part #8M0059529) may be required for proper operation. Consult your engine's manual or a marine technician if unsure.

Operating Instructions

The Sierra 63477P Fuel Gauge provides a clear and continuous indication of your vessel's fuel level. The dial is marked with 'E' for Empty, '1/2' for half-full, and 'F' for Full. The needle will move proportionally to the fuel level detected by the sender unit in your fuel tank.

• Reading the Gauge: Observe the position of the needle on the dial to determine the approximate fuel level.
• Scratch-Resistant Lens: The gauge features a scratch-resistant lens designed to maintain clarity and readability even after prolonged exposure to marine conditions.
• Domed Lens: The domed design of the lens helps to shed moisture, further enhancing visibility in wet conditions.

Maintenance

The Sierra Sterling Fuel Gauge is designed for durability and minimal maintenance. Regular care will help preserve its appearance and functionality.

• Cleaning: Clean the gauge face and bezel with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the lens or finish.
• Connection Inspection: Periodically inspect the electrical connections on the back of the gauge to ensure they are secure and free from corrosion. Loose or corroded connections can lead to erratic readings or gauge malfunction.
• Environmental Protection: While designed for marine environments, protecting the gauge from prolonged direct exposure to harsh elements when not in use (e.g., with a boat cover) can extend its lifespan.
