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!

Applications:


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.
