Pro Series Hydraulic Steering Cylinder
Pro Marine 700HSTEER-CYL Hydraulic Steering Cylinder
The Pro Marine 700HSTEER-CYL Hydraulic Steering Cylinder is a Pro Series hydraulic steering ram designed for high-performance marine outboard steering applications.
This steering cylinder is designed for use with the Pro Marine 700HSTEER hydraulic steering system and helps deliver smooth, controlled steering response for demanding marine applications.
What a Hydraulic Steering Cylinder Does
The hydraulic steering cylinder is the component mounted at the outboard engine that physically turns the engine when hydraulic pressure is applied from the helm pump.
As the steering wheel is turned, hydraulic fluid moves through the steering hoses into the cylinder, extending or retracting the steering ram to control engine direction. Steering cylinder sizing and construction play a major role in steering feel, control, and system durability.
