Technical Reference Manual
BAYSTAR OUTBOARD STEERING
NOTE: When properly installed, this steering system will
connect to outboard engines with ABYC standard tilt tubes,
using the engine's tiller arm. Use only BayStar outboard steering
tubing (HT44 type) with BayStar outboard steering systems.
All warranties will be void if any or all of these components are
misapplied. BayStar hydraulic steering is rated for 150 HP (total).
With mechanical steering you sacrifice a
degree of comfort, and traditional hydraulic
systems may be more than is needed on
lower horsepower outboard engines.
Built in the tradition of SeaStar, BayStar
brings the same efficiency and durability
you would expect from Teleflex Hydraulic
steering to smaller outboards up to 150 HP.
Compact form and affordable price make it
an ideal upgrade for mechanically steered
boats up to 150 total HP.
BayStar is for single-outboard powered boats
rated up to 150 HP, including runabouts and
inflatables and outboard engines with ABYC
standard engine tilt tubes up to 150 HP (total).
For single station, single engine use only.
BayStar is not intended for high speed, high
performance type boats, such
as Bass Boats.
