Teleflex BayStar Outboard Hydraulic Steering




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.



Applications:

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.
