Safe-TQC (mechanical steering, 3 turns lock-to-lock) Applications: Virtually all power-assisted stern drive boats with wheels up to 16" diameter. Safe-T QCT replaces all Teleflex Safe-T helms made since 1968 with little or no dash modifications. (Requires use of SSC62 QC steering cable.) For single station use only. Components are available for twin cable systems, but we recommend No-FeedBack steering for all twin cable steered outboards. See NFB Pro Rack & SeaStar PRO sections. Features: Quick-response of 3 turns lock-to-lock. Kits include: cable, helm, bezel and hardware. Standard 3/4" tapered steering shaft. Stainless steel cable output ends. Fast, easy installation: uses simple snap-in cable connection, Teleflex Quick Connect (QC) cable, and industry-standard Safe-T mounting hardware. Meets A.B.Y.C. standards. Meets N.M.M.A. certification requirements. How to Measure Cable: For a New Installation: Measure Cable Routing Path in Boat as follows: A = Center line of wheel to gunwale, B = Dash to transom, C = Gunwale to centerline of cable connection at centered tiller. For Tilt Tube Mounting, add A, B & C + 6", round up to next even foot. For Transom/Splashwell/Stringer Support Mounting, add A, B & C, then subtract 6" and round up to next even foot. Order that length cable.
