Teleflex Marine NFB 4.2 Mechanical Rotary Steering System

NFB 4.2 Mechanical Rotary Steering System

Patented No FeedBack Steering Control for about the cost of an old-fashioned steering replacement. With the advantage of 4.2 turns lock-to-lock and the patented No Feedback steering to lock out steering load, 4.2 Rotary NFB Steering is the ideal single-cable system for most non-power-steered boats. The helm is a drop-in replacement for current generation Safe-T with no dash modifications required.

Applications:

• NFB 4.2 single-cable systems are suitable for most single-station boats with a single non-power-assisted outboard engine up to V-6 and minimal engine flutter or steering instability.  4.2 Accepts steering wheels up to 16" diameter.
• Use dual cable system for boats with engine flutter or steering instability.
• Replaces nearly all Teleflex safe-T steering systems without dash modifications.
• Features:

Patented No Feedback Steering mechanism.

Comfortable 4.2 turns from lock-to-lock

Minimal clutch free play.

Standard 3/4" round tapered steering shaft.

Stainless steel cable output ends.

Fast, easy installation:  uses Quick Connect (QC) steering cable.

Kits include: cable, helm, 90 degree bezel and hardware.

Meets A.B.Y.C. standards

Meets N.M.M.A. certification requirements.

How to Measure Steering Cables “Measure Twice. Order Once.”

Replacement of Existing Cable: If possible, find the part number stamped on the plastic jacket of the old cable. If you removed the old cable, measure for the replacement cable as follows:

For Rotary Steering Cable Replacement, Measure Existing Cable as follows: Measure plastic cable jacket (“Y” dimension, shown in above drawing) in inches, add 18″, and round up to next foot. Order that length cable.

New Installation: Measure cable routing path from wheel center line to engine connection, as follows: A = Center line of wheel to gunwale (or deck, if routed downward), B = Dash to transom, C = Gunwale to centerline of cable connection at centered tiller.

For Cable Installations through the Engine Tilt Tube: Add A, B & C + 6″, then round up to the next foot. Order that length cable.

For Cables Mounted to Transom, Splashwell or Stringer: Add A, B & C, then subtract 6″ and round up to the next foot. Order that length cable.

TYPICAL SINGLE STATION ROUTING

A single-cable, starboard drive push-pull mechanical cable system is shown in this diagram. If your mechanical system is different than the one depicted and/or you have any questions about mechanical steering after reviewing this guide, please contact Teleflex (Mechanical) Technical Service at (610)-495-7011 or www.teleflexmarine.com

Cable routings (such as those found on pontoon boats) may vary from this drawing. Confirm length by laying a garden hose or similar object) along cable path and measure run from wheel to engine connection point.
