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.
