Teleflex JBS Jet Boat Mechanical Steering

Technical Reference Manual

Just for Jets! JBS by Teleflex means Jet
Boat Steering! Designed exclusively for jet
boats, JBS features a choice of two steering
arcs, a real steering cable (not a control
cable) plus an assortment of mounting
options for virtually any boat! Nobody knows
steering like Teleflex!


Teleflex JBS is recommended for use in all jet boat applications powered
by Mercury Sport Jet or OMC Turbo Jet drives up to 175 HP.

NOTE: When properly installed, this steering system will connect to
Mercury Sport Jet and OMC Turbo Jet and similar small jet drives, using
the appropriate nozzle connection kit (and possibly through-hull fittings
which are not available from Teleflex). Please contact Teleflex Marine
Technical Service (610-495-7011 or www.teleflexmarine.com) if you need assistance.
