Engineered for boats with mechanical throttle and shift, the KE-4+ is the perfect answer for smooth and easy shift and throttle control in almost any application. It offers modern styling and various color/finish control head options. It eliminates cable slack and friction for long or multiple station applications and is designed for new or retrofit installations. Can be used with inboards, outboards or stern drives with either gas or diesel engines and 12 or 24 volt applications. Includes a built-in engine synchronizer in either single or dual lever models. Features include: up to 4 station capability, neutral warm-up function, optional mechanical backup, adjustable shift pause and throttle delay, start in gear protection, optional trolling system, and more. All systems below require a NM0649-XX bus harness between each control head and each control unit. We recommend CCX633XX series control cables between the actuators and the engines. Specify length of cables and harnesses. All configurations require a hardware kit.
