®
BIG-T® MECHANICAL ROTARY
STEERING (DUAL) SYSTEM:
The Original SeaStar Solutions Steering
System! For over 50 years, Big-T® has been
the most durable and 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.
Uses a special-order, non-returnable type cable
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.
