INTRODUCTION
SeaStar PRO Outboard Steering systems are suited for all those critical high speed, single powered outboard boats, like Bass, Flats, combo Race/Ski and other performance orientated boats capable of speeds in excess of 65mph. Before ordering it is necessary to determine the proper cylinder and helm pump for your application. See application guide below.

Notes
• Do NOT use with unbalanced cylinder.
• SeaStar PRO is for single engine applications only.
• The recommendations shown above apply to factory stock outboards only. Modified installations may require a higher capacity steering system. (Cylinder volume / helm displacement = number of turns.) If in doubt, contact Teleflex Canada technical service for assistance.
• Some applications vary from what is depicted in this catalog. Always consult SeaStar manual for diagrams specific to your application.
• Interference between the cylinder and boat can occur under certain conditions. Check installation thoroughly throughout the full range of movement for engine tilt and trim (and jack plate, if present).
• For all Seastar PRO outboard systems: use only SeaStar PRO Hose Kit Part No. HO57_ _ or HO82_ _, where last two digits equal length in feet.
