Pacer Yellow 16 AWG Primary Wire - 500'

The Pacer Yellow 16 AWG Primary Wire – 500' is purpose-built for marine electrical systems where salt spray, moisture, and temperature fluctuations demand uncompromising reliability. Whether you're running auxiliary circuits on a center console, connecting trolling motors, or upgrading your boat's charging system, this wire delivers the durability needed for harsh saltwater environments. With 500 feet of coverage, a single spool eliminates mid-project supply runs and provides enough capacity for most mid-sized vessel installations or repairs.

Manufactured in the USA to exceed stringent marine specifications, this primary wire features robust insulation that resists UV exposure, oil, gasoline, and corrosion—critical for topside and engine compartment routing. The 16 AWG gauge provides the ideal balance for low-voltage accessory circuits, house batteries, and navigation system feeds without excessive voltage drop over moderate distances. Pacer's marine-grade construction ensures the insulation remains flexible in cold water temperatures while maintaining integrity under the thermal stress of summer operation, making it suitable for both freshwater and saltwater applications.

This wire works best for 12V and 24V DC systems commonly found on fishing boats, cruisers, and recreational vessels. The yellow jacket aids quick identification during installation and troubleshooting, reducing the risk of cross-connection errors. Professional marine electricians and serious DIY boaters appreciate the pre-cut spool format—no guessing on length, no waste, and consistent diameter for clean bundling along stringers and bulkheads. Pair this primary wire with proper marine connectors, heat shrink, and crimping tools to ensure corrosion-free connections that last seasons of hard use.
