Pro Marine 700HSTEER-CYL Hydraulic Steering Cylinder

Pro Series Hydraulic Steering Cylinder for 700HSTEER Systems

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.

Pro Tip: Hydraulic steering cylinders should always be matched with compatible helm pumps, hoses, fittings, and steering system components to ensure proper steering response and safe operation.
