Mercury - Thruster Power to Battery Cable (10 ft) Rigging Accessory 84-8M0174059. OverviewThis 10-foot power cable supplies clean, direct battery power to a bow or stern thruster. It's the red lead used to keep the thruster energized without voltage drop or sketchy connections. The length works well for most pontoon and JPO-style installs where the battery isn't too far from the thruster module. Once it's in place, you'll usually notice stronger, more consistent thruster response.. Key Features
