108 ® BIG-T® MECHANICAL ROTARY STEERING (DUAL STATION) SYSTEM: The Original SeaStar Solutions Steering System! For over 50 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 encased in a rugged gear housing. It’s no wonder owners of small inboards have counted on the SeaStar Solutions Big-T since 1963! APPLICATIONS: Inboards up to 34 feet. Also suitable for sterndrive boats with power-assisted steering. Big-T systems accept steering wheels up to 20" diameter. The type of system shown on this page is for dual station use. For single station Big-T, please see the previous page. FEATURES: Available in single or dual station versions. (See previous page for single station version.) Responsive 3 turns from lock-to-lock. Standard 3/4” round tapered steering shaft. Stainless steel cable output ends. 2-piece bezel for 90° or 20° helm mount to dash. Optional 1-piece 90° bezel for compact mounting. Uses a special-order, non-returnable type cable SSC81AxxBxx. † Meets A.B.Y.C. standards. Meets N.M.M.A. certification requirements. Made, designed and assembled in the USA. HOW TO MEASURE CABLE FOR DUAL STATION BIG-T: For a Big-T dual station steering system, the cable required is SSC81AxxBxx, 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 special order non-returnable. COMPLETE SYSTEM This steering system is sold by components.
