The idea behind the Twin Disc Express Joystick System is that it can revolutionize docking and slow-speed maneuvering in diesel-powered boats with conventional straight shafts and propellers. There is no need to redesign the hull or introduce pods or tunnels. The Twin Disc system simultaneously engages the engines, transmissions, and thrusters to maneuver the boat in any direction instantaneously, with no lag time. The key is Twin Disc’s Quick Shift transmission with a patented clutch that can slow the propellers down to as low as 50 rpm. If you haven’t operated this system, do yourself a favor and try it at the next boat show. It’s worth it!
