Teleflex Big-T Inboard Mechanical Steering - Dual Station

Technical Reference Manual


Dual Station System
(3 turns lock-to-lock)

NOTE: When properly installed, this steering system will connect to

The Original Telefl ex Steering System!
For over 35 years, Big-T has been the most durable, versatile mechanical
steering system made, with both single and dual station capability. The heavy
duty helm incorporates a strong steel pinion, dual diecast gears and meaty
shaft bearing supports, all en cased in a rugged gear housing. It's no wonder
owners of small in boards have counted on the Teleflex Big-T since 1963!


Inboards to 34 feet with one or two engines. Also suitable for stern drive boats with power assisted steering. Big-T systems accept steering wheels up to 20" diameter.

The type of system shown on these pages is for dual station use.

    How To Measure Cable
    for Dual Station Big-T:

    For a Big-T dual station steering system, the cable required is SSC81AxxBxx (see parts list above), where xx = the lengths of the two cable sections in feet. The letter "A" in the part number represents the cable routing path distance between steering stations. The letter "B" represents the cable routing path distance from the lower station to the engine/rudder area. The different cable lengths are available in one-foot increments only.

    EXAMPLE: if the cable routing from engine to lower station is 18 feet and 10 feet from station to station, order part number SSC81A10B18 cable.

    NOTE: Please be sure of your measurements because this cable is non-returnable.
