The ConnectPro trolling motor plug and receptacle system is a revolutionary concept in trolling motor DC connections. The superior electric current carrying capacity of the ConnectPro system eliminates problems that rob motors of power and reduce battery life. Also, features a spring clamping connection that provides a secure electrical contact. Perma-Lock terminals have a special screw locking connection. Extreme hull vibration and heat cycling can not loosen the screw. No special crimping tools, wire connectors, shrink tubing, or tape needed. Soft contoured cover keeps away dust and moisture and makes hook-ups and blade alignment easy.
