Using your Faria Coral 4 - inch speedometer is easy. First, install the pitot tube (sold separately) on your boat in the right position so it can sense the water pressure. Then, connect the flexible tubing from the pitot tube to the speedometer head. Make sure the voltage input (12/24V) is properly connected. When you're out on the water, the speedometer will show your speed based on the water pressure. As for maintenance, keep the lens clean with a soft cloth to maintain clear visibility. Check the connections regularly to ensure they are tight and free from corrosion. If you face any problems, don't return it to the place of purchase. Instead, get in touch with the manufacturer. Remember, the gauge cover is not included, so you may want to protect it from the elements if needed.
