Got a sticky throttle or shift on your Mercury or Mariner outboard? This Winibo control cable is the direct replacement you need. It's the CC635 type, a 13-foot long cable designed specifically for 1965 and newer Mercury and Mariner single-lever controls (replaces part numbers CC635 or CC179). Winibo has been making control cables for over 35 years, so they know their stuff. This cable is built for performance: it has extremely low friction for smooth operation, very little idle play (so your controls feel precise), and high tensile strength. It also has a small bending radius for easier routing in tight engine compartments. It's super durable and tested to handle extreme temperatures and over 250,000 push-pull cycles. If your old cable is frayed, corroded, or just getting stiff, swapping in this one will restore that smooth, reliable control you expect from your boat.
