SeaStar 061371 Dual Station Transfer Unit for Single Function ControlsThe SeaStar 061371 Transfer Unit is only for use with single function controls using 3300/33C control cables. The Dual Station Transfer Unit from SeaStar Solutions is recommended where long or difficult cable paths make parallel installations costly and/ or difficult. When single function two lever controls are used in a parallel, dual station application, some installations may cause the clutch or throttle levers to operate "stiff". Adding a transfer unit can improve control performance in these cases.
