Pro Marine 350-HSTEER-CYL Hydraulic Steering Cylinder

Replacement Hydraulic Cylinder for 350-HSTEER Systems

Replacement Hydraulic Steering Cylinder

Pro Marine 350-HSTEER-CYL Hydraulic Steering Cylinder

The Pro Marine 350-HSTEER-CYL Hydraulic Steering Cylinder is the replacement steering cylinder used with the Pro Marine 350-HSTEER hydraulic steering system. It is designed for high-horsepower single outboard setups where smooth, controlled steering response is critical.

This is the cylinder only. Helm pump, hoses, steering fluid, and fill/bleed accessories are sold separately unless purchased as part of the complete 350-HSTEER system.

What This Cylinder Is Used For

The steering cylinder converts hydraulic pressure from the helm pump into side-to-side movement at the outboard engine. It is the component that physically moves the engine when you turn the steering wheel.

If your current cylinder is leaking, damaged, binding, or worn, replacing it can restore proper steering control and improve the overall feel of the system.

Pro Tip: When replacing a steering cylinder, inspect your hydraulic hoses, helm pump, fittings, and fluid condition at the same time. A clean hydraulic system helps protect the new cylinder and improves steering performance.
