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.
