Teleflex HPS Rack & Pinion Mechanical Steering

Technical Reference Manual


NOTE: When properly installed, this steering system
will connect to engines with ABYC standard tilt tubes, using
engine manufacturer's link arm. For other engines, see Steering
Connection Kits section for options.

Best System for Power-Assisted Steering
(4 turns lock-to-lock)

HPS Rack by Teleflex is the best 4-turn way to steer a
power-assisted stern drive or outboard!

Ideal for small inboards too, HPS reduces backlash
(free-play at the wheel) associated with power steered
boats by up to 50%!

A great choice for ski boats, too!


HPS Rack is ideal for all power-assisted stern drives that can
accept a mechanical steering cable and have adequate room for a
rack & pinion steering cable behind the dash.

It replaces most standard Teleflex and Morse Rack & Pinion
steering without dash modifications.

HPS Rack is available in single cable configuration and is for
single station use only. It accepts wheels up to 16" diameter.
