Uflex MasterDrive Steering System – Single Station Twin Cylinder Kit – MD40-D1F

The Uflex MasterDrive MD40-D1F Steering System is a premium hydraulic steering solution engineered for high-performance, high-horsepower powerboats requiring maximum control, redundancy, and steering precision. Designed as a single station, twin-cylinder system, this complete kit delivers exceptional handling, reduced steering effort, and confidence-inspiring response at both cruising and top-end speeds.

At the heart of the system is the Uflex MasterDrive 40cc helm, optimized to provide smooth, responsive steering with fewer turns lock-to-lock, making it ideal for offshore boats, center consoles, and performance vessels. Paired with dual UC128TS hydraulic steering cylinders (SVS 1 & SVS 1P), the MD40-D1F system ensures balanced hydraulic pressure on both sides of the engine, improving tracking, stability, and control—especially on twin-ram outboard and high-torque applications.

The twin cylinder configuration not only enhances steering power and precision, but also adds an extra layer of reliability for demanding offshore conditions. Built using corrosion-resistant, marine-grade materials, the MasterDrive system is designed to perform flawlessly in both freshwater and saltwater environments.

Whether you’re repowering, upgrading from mechanical steering, or replacing an aging hydraulic system, the MD40-D1F MasterDrive Kit delivers professional-grade steering performance trusted by serious boaters and marine professionals worldwide.

Essential Installation Notes

Please note that this kit contains the core power and steering components, but does not include the following items which must be purchased separately to complete the installation:

1. Hydraulic Hoses: You will need a SilverSteer™ high-pressure hose kit (Helm to Power Unit and Power Unit to Cylinders).

2. Tie Bar: A mechanical tie bar (such as the Uflex A90) is required to synchronize the movement of the twin engines.

3. Steering Wheel: The helm features a standard 3/4" tapered shaft compatible with most marine wheels.

The Uflex MasterDrive MD40-D1F Steering System is built for boaters who demand uncompromising control, durability, and confidence on the water. With its twin-cylinder design and premium hydraulic components, it delivers the smooth, precise steering performance needed for today’s powerful marine engines.
