Teleflex Mercury Gen II Cables

Teleflex Mercury Gen II Control Cables: Precision Engineered for Mercury-Powered Boats

When your throttle and shift response need to be crisp, reliable, and fatigue-free on the water, the connection between your control box and your engine matters more than most boaters realize. Teleflex — now operating under the SeaStar Solutions family of brands — has long been one of the most trusted names in marine control systems, and their Mercury Gen II cables represent that expertise applied directly to Mercury, Mariner, and Force outboard and sterndrive applications.

What Are Mercury Gen II Cables?

Mercury Gen II cables are a specific cable interface standard used by Mercury Marine's 4000-Series control boxes, including many popular single-lever and dual-action throttle/shift controls found on outboards and sterndrives. These cables feature a distinct end fitting that differs from universal 3300/33-type cables, so using the correct Gen II-compatible cable is essential for a proper, play-free fit. Teleflex's 189 Series and TFXtreme (CCX) Series are both purpose-built to meet this standard, giving boaters a range of options from dependable everyday replacements to premium performance upgrades.

The TFXtreme Advantage

Teleflex's flagship TFXtreme Gen II cables (CCX Series) go well beyond a basic drop-in replacement. The TFXtreme's unique design incorporates a patent-pending splined core, which creates minimal contact points between the core and liner — the ridges allow a close fit while keeping friction to a minimum, so the core glides back and forth smoothly with easy movement and minimum lost motion.

Premium TFXtreme cables feature the Xtreme splined, coated core element for maximum smoothness and minimal lost motion, while the HDPE casing adds durability and provides great resistance to UV, saltwater, chemicals, gasoline, and oil. For boaters operating in harsh saltwater environments or running their engines hard day after day, this level of material protection is a genuine advantage.

Each cable includes stainless steel and brass fittings, and the premium heavy jacket paired with the Xtreme splined core delivers maximum smoothness and minimal lost motion. These cables meet or exceed NMMA, ISO, IMCI, and ABYC standards — the key industry benchmarks for marine safety and performance.

189 Series: The Reliable Standard Option

The Teleflex 189 Series Gen II Mercury cables are available in a wide range of lengths, from 10 feet through longer runs , making it straightforward to find the right fit for virtually any helm-to-engine distance. Teleflex cables are manufactured with chemical-resistant casing and can be used to replace original equipment cables from brands like Mercury MerCruiser using existing components , which means no adapter kits and no surprises during installation.

Choosing the Right Length and Series

Both the 189 Series and TFXtreme CCX Series are available in one-foot increments , so you can select the precise run length your installation requires. When upgrading from a worn OEM cable, the TFXtreme is a worthwhile step up for boaters who want a noticeably lighter, more responsive lever feel — particularly on twin-engine setups where control fatigue can add up over a long day on the water.

Whether you are doing a straightforward maintenance swap or building out a new control station, Teleflex's Gen II cable lineup for Mercury delivers the engineering quality and marine-grade durability that experienced boaters depend on season after season.
