Big-T® Rotary Steering

The Original Teleflex 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 encased in a rugged gear housing. It’s no wonder owners of small inboards have counted on the Teleflex Big-T since 1963!
