This is the non-tilt version of SeaStar Solutions' top-of-the-line Xtreme™ series of rotary cable steering systems.

Xtreme NFB* (No FeedBack) Mechanical Steering systems offer the smoothest and lowest effort single cable mechanical helm in the marine industry...yet, they are still easy to install.

These single rotary cable steering systems are suitable for most single steering station boats with a single outboard, or a single sterndrive without power assisted steering - where feedback reduction is a real benefit. A typical engine size limit is up to a V-6.
However, if your non-power-assisted installation exhibits engine flutter or other steering instabilities, a dual cable system is recommended to help minimize these issues. Since Xtreme NFB™ Steering Systems are only available in single cable versions, you will have to use one of SeaStar's other NFB systems for dual cable (high engine flutter) applications. See Related Products, below.

These Xtreme steering systems feature newly designed components:
- The new helm has a completely new gear train designed to provide smooth feel, minimal backlash, and low effort at the wheel. It also offers smoother NFB clutch release, and has a smaller footprint than SeaStar's 4.2 turn NFB rotary helm units (better for smaller/crowded dashboards). All castings are designed to reduce weight while offering superior strength.
- New bezel design.
- A brand new Xtreme steering cable was designed specifically for this system. Xtreme cables offer unprecedented smooth action and low effort with minimal "slop". This is because, compared to other cables, the splined liner and powder-coated core make for reduced surface contact and less friction between the sliding components. Furthermore, the internal tolerances around the cable are tighter - resulting in less backlash (lost motion) inside the casing. This means that when you turn the wheel, the engine responds instantly, without any wheel looseness or play. The new Xtreme cable construction is also stronger - allowing the cable to withstand higher loads when circumstances require.

• Improved NFB function for smoother release
• 5 wheel turns lock-to-lock for low effort, precise steering
• Reduced cable slop - for less wheel play and reduced engine flutter
• Helm is constructed of a reliable Zamac casting and zinc-plated steel
• Quick connect mechanism on both cable ends and spent travel tube sides for easier installation - no tools required
• Installs in same mounting bolt pattern and bracket location as current SeaStar steering systems
• Smallest footprint possible fits all existing installations and accommodates small or tight dashboard helm stations
• Helm
• No electrical wiring; no bleeding of hydraulics
• Designed, manufactured, and assembled in the USA

Compltete kit includes — (SHX7606) Xtreme NFB helm, bezel, and mounting hardware kit, plus an SSCX64xx Xtreme Quick Connect steering cable and connecting hardware (the "xx" in the part number is the length of the cable in feet).

* What is NFB?
NFB stands for No FeedBack, and is an exclusive feature built into SeaStar Solutions helms to fight propeller torque feedback.
In standard mechanical steering systems, the turning of the propeller creates a torque force which can be felt in the steering wheel as a tendancy for the boat to constantly want to turn in one direction. To keep the boat going straight, this veering must be constantly "fought" by the person steering the boat.
A corollary effect is that the boat can be turned in one direction with just one finger, but requires two hands to turn in the other direction. This is especially apparent with larger engines (over 40 - 50 horsepower), as well as at higher speeds.

For about a hundred bucks more than a standard helm mechanism, SeaStar Solutions NFB helms incorporate an internal clutch mechanism that significantly decreases the tiresome effect of prop torque — without having to spend an extra thousand dollars for an hydraulic system to completely eliminate it.

Whereas, when you take your hands off the wheel with a standard mechanical steering system the boat will quickly start to turn of its own accord, with an NFB system that turning tendency will be much slower to start and can be controlled with less effort.
A hydraulic system, on the other hand, will completely eliminate propeller torque feedback, so you can take your hands off the wheel, and the boat will continue to track straight (all other things being equal). Hydraulic steering is a real advantage with larger engines, and is highly recommended for those applications.

In case you were wondering, boats with inboard engines do not experience prop torque since you steer them with a rudder, not by having to turn the entire drive unit and propeller - as with an outboard or I/O.

NFB steering helms should never be used with autopilots or power assisted steering systems.

Xtreme series steering cables can only be used with Xtreme series helm units.
