MARINCO ConnectPro 3-Wire Receptacle and Plug System

MARINCO ConnectPro 3-Wire system is engineered for marine charging and trolling motor power connections. Core features include O-ring sealed plugs for waterproof connections, weather-resistant plug covers, and corrosion-resistant plated brass electrical components with drain holes in receptacles to keep water away from contacts. Receptacles use Perma-Lock screw terminals to resist loosening under hull vibration and mount in a standard 1-1/8" diameter hole for straightforward installation. The family supports universal 2- or 3-wire configurations across 12V, 24V and 36V systems, accepts 16 to 8 AWG in many models (with a 6-gauge adapter available), and is rated up to 40 amps. Variants include individual plugs, receptacles, combined kits and adapters to meet common marine power and trolling motor needs.
