Technical Reference Manual

NOTE: When properly installed, this steering system will connect to outboard engines with ABYC standard tilt tubes, using the a drag link and the engines tiller arm. Use only SeaStar outboard steering hoses (HO51/HO57 type) with SeaStar outboard steering systems. Use of nylon tubing is not recommended for SeaStar outboard steering.

A great alternative for wide, shallow splashwells. SeaStar side mount steering is a good choice for engines with threaded tilt tubes that comply with ABYC P17/NMMA/BIA standards for mechanical steering. The cylinder attaches to an engine tilt tube which meets the above standards.

Applications:

Single and dual non-power-assisted outboard engines up to 300 HP (600 combined HP for counter-rotating duals) that have standard engine tilt tube.

Suitable for speeds up to 60 MPH and dual station use (with purchase of extra helm, hose & fittings).

Dual engines require purchase of a tie bar kit and extra hardware. For power steered engines, contact Teleflex Canada Tech Service at www.teleflexmarine.com or 604-270-6899.

Features:

  • Drag link design fits most engines with threaded tilt tubes. Fast, easy installation.
  • Alternative to front mount cylinder where space allows, especially useful in boats with shallow splashwells.
  • Suitable for use on enghines with power steering.
  • 4.8/5.7 turns lock to lock* (unbalanced cylinder).
