When it comes to choosing the right steering system for your vessel, size and specifications matter just as much as quality. Whether you operate a cargo ship, an engineering vessel, or a fishing boat, having a reliable steering system ensures safe navigation, precision maneuvering, and confidence in challenging sea conditions.
At SINOOUTPUT, we specialize in advanced marine control systems, and our Marine Electric Dual-Motor Steering System is designed to deliver flexible operation, fast response, and high reliability. But the big question many shipowners ask is: What size steering system is right for my vessel?
In this guide, we’ll walk you through the factors you need to consider when selecting a steering system, the features of our dual-motor design, and how to determine the right fit for your ship.
Why Steering System Size Matters
A steering system that’s too small for your vessel won’t deliver enough hydraulic force, leading to sluggish or incomplete rudder movement. On the other hand, an oversized system may add unnecessary weight, cost, and energy consumption.
The goal is to match the motor power, hydraulic cylinder capacity, and control configuration with your vessel’s displacement and steering requirements.
Key Parameters of the SINOOUTPUT Marine Dual-Motor Steering System
Our Marine Electric Dual-Motor Steering System is engineered to balance power, redundancy, and precision. Here are its core specifications:
Control Panel: 1.8m three-cabinet stainless steel control station with integrated helm, instruments, and switches.
Steering Options: 304 stainless steel manual wheel + electronic steering wheel for redundancy.
Motors: Two marine-grade motors, each 5.5kW, 220V, 50Hz, three-phase, driving the hydraulic pump station.
Hydraulic Cylinders: Dual 6.3-ton rudder cylinders, enabling ±35° steering control.
Pump Station: Electrically controlled dual pump station with belt-driven pumps.
Backup System: Manual hydraulic steering system in case of electrical failure.
Instrumentation: Rudder angle indicator, pressure gauge, speedometer, voltmeter.
Safety & Reliability: Waterproof, corrosion-resistant structure for long-term performance in harsh marine environments.
How to Choose the Right System for Your Vessel
When deciding what size steering system you need, consider the following:
Vessel Type and Size
Cargo ships and engineering vessels often require dual-cylinder, high-torque steering.
Smaller vessels may use single-motor systems, but dual-motor ensures redundancy and safety.
Motor Power Requirements
Each motor in the SINOOUTPUT system is 5.5kW, sufficient for medium-to-large vessels needing reliable, continuous operation.
Hydraulic Cylinder Capacity
Our dual 6.3-ton cylinders provide the force required for precise rudder control even under heavy loads.
Operational Environment
If your vessel frequently operates in harsh sea conditions, a dual-motor, dual-pump system provides the resilience you need.

Common Questions About Sizing
Q1: Can I use this system on a small fishing vessel?
While possible, the dual 5.5kW motors and dual 6.3-ton cylinders are typically best suited for medium-to-large vessels. For smaller boats, a lighter-duty system may be more efficient.
Q2: What happens if one motor fails?
The system can continue running on a single motor, or operators can switch to the manual hydraulic steering system.
Q3: Does it work with standard ship power supplies?
Yes, the system runs on AC 220V, 50Hz, three-phase, which is standard for marine electrical systems.
Selecting the right steering system for your vessel is all about balance: power, reliability, and safety. With SINOOUTPUT’s Marine Electric Dual-Motor Steering System, you get a robust, flexible, and redundant solution designed for today’s demanding marine environments.
If you’re unsure whether this system is the right fit for your vessel, our engineering team can help you evaluate your ship’s specifications and recommend the best configuration.
