From monitoring the condition of your boats engine to the fuel status, your gauges are no less important on your boat than in your car. Although typically less complicated than the gauges in a vehicle, boat gauges are none the less just as important. In fact, due to extreme conditions including corrosion, temperature, and vibration, certain considerations must be made for boat wiring which do not come into play with vehicles.

Tips & Warnings
Use a high quality 16 gauge marine-grade wire for most gauge applications. However, for fuel pumps, 14 gauge wire is a better choice. Other wiring applications, such as audio systems and specialty electronics, should be referred to the manufacturer of each product.
Use caution any time you work with or around a battery. Wear proper protective eye glasses and gloves. Use caution when working with any hand tools. Make sure you are familiar with wiring principles and understand the potential hazards of working with batteries and electrical currents.
