This is the non-tilting version of SeaStar Solutions' 4.2 NFB* Single Cable Rotary Steering Kit.
It offers the advantage of 4.2 wheel turns lock-to-lock, plus SeaStar's patented No FeedBack steering control for about the cost of an old-fashioned steering replacement.
The helm is a drop-in replacement for current generation Safe-T® steering systems with no dashboard modifications required. It accepts steering wheels up to 16" in diameter.

The advantage of 4.2 steering wheel turns lock-to-lock over 3.0 turns is that you will exert less effort when steering, although the turning response time will be somewhat slower. This helm offers more precision and control when steering.

Single cable steering is the ideal system for most single station, outboard and non-power-assisted sterndrive engines up to a V-6, that exhibit minimal engine flutter or steering instability.
A comparable dual cable system is made for applications with engine flutter or steering instability. See Related Produxcts, below.

• Patented No FeedBack™ steering mechanism
• Comfortable 4.2 turns lock-to-lock provides precise steering
• Standard 3/4" tapered shaft
• Stainless steel cable output ends resist corrosion
• Fast, easy installation using Quick connect (QC) steering cable(s)
• Meets ABYC standards and NMMA certification requirements
• Note: tilt helm available - single cable helm TFX #SH91526P and dual cable helm TFX #SH91527P

Kits include: QC Cable (SSC62xx) (2 cables for dual systems), helm (SH4910P single, SH4920P dual), 90° bezel (SB27150P), and hardware.

* 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.
