Garmin Threaded Collar CCU Extension Cable - 25M

Extending the reach of your Garmin marine autopilot system's Course Computer Unit (CCU) just got simpler and more reliable. This 25-meter threaded collar extension cable gives you the flexibility to position your CCU exactly where it works best on your vessel, far beyond the standard 3-meter limit from the Electronic Control Unit (ECU). Ideal for larger boats or custom installations where space and layout demand extra length without compromising performance.

Why Choose the Threaded Collar Design?

In the harsh marine environment, secure connections are non-negotiable. The threaded collar mechanism locks in place firmly, resisting vibrations from rough seas, engine rumble, and constant boat motion. Unlike basic plug-and-play cables, this design minimizes signal interference and ensures a watertight seal, protecting against saltwater corrosion and spray. Boaters report fewer disconnects during long offshore runs, keeping your autopilot steering true when you need it most.

Seamless Integration with Garmin Autopilot Systems

Engineered specifically for Garmin's lineup, this cable pairs effortlessly with systems like the GHP™ 12 and Reactor™ 40 Kicker Autopilot. It maintains the precision GPS navigation and responsive steering these units are known for, even over extended distances. Whether you're retrofitting an older setup or building a new helm station, the black sheath blends discreetly with onboard wiring, maintaining a clean, professional look.

Practical Installation Tips for Marine Pros and DIY Enthusiasts

Routing this cable through bulkheads or along deck runs is straightforward—its durable jacket flexes without kinking, and the 82-foot length covers most monohull or multihull needs. Start by powering down your system, disconnect the existing CCU harness, and thread the extension in series. Use cable ties and conduit for protection against chafe from fishing gear or sails. Test the autopilot in calm waters post-install to verify hold courses and responsiveness. Pro tip: Label both ends for quick troubleshooting during maintenance seasons.

Boosting Reliability on the Water

Beyond extension, this cable enhances overall system uptime. Garmin's commitment to rugged utility shines here—think awe-inspiring durability that handles UV exposure, temperature swings from tropics to high latitudes, and the daily grind of recreational or commercial boating. Paired with Garmin's one-year limited warranty, it's a smart upgrade for peace of mind, reducing downtime and keeping your voyages on course.

Boat owners upgrading from shorter cables often notice smoother operation in autopilot modes, especially during autopilot handoffs or NMEA 2000 network expansions. It's not just wire; it's the difference between a cramped install and a optimized one tailored to your boat's unique helm dynamics.
