UC128-SVS Front Mount Hydraulic Steering Cylinders

In applications with dual UC128-OBF cylinders it is necessary to order a "standard" cylinder (with a link arm attached to the starboard side of the cylinder) and a "port" cylinder (with a link arm attached to the port side of the cylinder).
This translates into ordering a standard UC128-OBF cylinder and a UC128P-OBF cylinder for combined engine horsepower under 500 HP...
...or a UC128-SVS cylinder and a UC128P-SVS cylinder for combined engine horsepower over 500 HP.


Specially designed for high performance, high torque applications the SilverSteer™ UC128-SVS cylinder is recommended for bass boats, flat boats and tournament fishing boats with a combined engine horsepower over 500 HP.

The UC128-SVS is built to last with heavy duty stainless steel cylinder rod, seals and link assemblies. Constructed of top grade materials this cylinder is simple to install and fits almost every 2- and 4-stroke outboard engine on the market. See the application guide next page to choose the appropriate cylinder (UC128-SVS/1, UC128-SVS/2 or UC128-SVS/3) for your application.
• Adjustable boss style fittings for easy installation
• High resistence stainless steel connection bolt (ULTRABOLT) Depending on the applications on the outboard engines, the UC128-SVS is available in 3 versions:
UC128-SVS/1 - 41281U
UC128-SVS/2 - 41282W
UC128-SVS/3 - 41283Y

In applications with dual UC128-SVS cylinders it is necessary to order a standard UC128-SVS cylinder (link arm attached to the starboard side of the cylinder) and a port UC128P-SVS cylinder (link arm attached to the port side of the cylinder).
See appropriate section for A90 tie bar, required for dual engine/dual cylinder applications.
Depending on the applications on the outboard engines, the UC128P-SVS port cylinder is available in 2 versions:
UC128P-SVS/1 - 41328U
UC128P-SVS/2 - 41329W
