The new Dual Station (DS) unit is designed for inboard or sterndrive boaters that like using one lever to do both throttle and shift in their dual station boat. The Station Selector allows smooth operation of dual function controls in a dual station application. Great for dual station boats without a lot of dash space or for use with side mounted controls in two stations. Just put both levers in neutral, turn the selector switch, and you have changed stations. Teleflex recommends to only use CCX633xx cables with the DS Unit. Note: Throttle cables should be a pull to advance throttle set up. Engine adapter kits for the control cables are needed unless provided by the manufacturer. Control boxes not included.
