Mercury - Gen II Throttle and Shift 25 Ft Mechanical Control Cable - 8M0085124. This Gen II throttle and shift cable is built for Mercury mechanical control systems that require maximum routing flexibility. It's commonly used on large consoles or boats with long helm-to-engine runs where shorter cables feel tight or strained. The twenty-five foot length allows the cable to route smoothly without sharp bends or tension points. It's a solid choice when a clean, stress-free installation matters.. Using the correct cable length helps maintain smooth throttle response, predictable shifting, and reduced internal wear. Replacing undersized or aging cables improves overall control feel and helps protect the control system over time.. Key Features. Gen II mechanical cable design provides smooth and consistent control movement. Twenty-five foot length supports very long control runs without binding. Low-friction inner core maintains steady and predictable control effort. OEM Mercury construction
