My 25 already had the second helm installed, but with hydraulic steering it's really no different than adding an autopilot as far as the hydraulics go. The previous owner had a throttle control for the kicker installed at that second helm as well. So while I can steer both engines from either the cabin or cockpit helm, the main throttle is only controlled at the cabin helm and the kicker throttle is only controlled at the cockpit helm. Colby
