Introducing Livorsi Marine's New QR Series™ throttles (Quick Response) designed specifically for all Mercury compatible DTS engines. These ergonomically designed knobs are very comfortable on the palm of your hand for long periods of throttling. The shorter levers and throw of the Livorsi QR Series™ make this control great for tight dash spaces and aggressive throttling. With up to 3 trim switches integrated into the knob, your hand never has to leave the control. Electronic shifting and throttle make it easier to maneuver in tight docking spaces. Create your own color combination to make this control look and feel like a custom built control. Available in single, twin engines and Shadow Mode*.
