37cc Hydraulic Steering Helm Pump
Pro Marine 350-HELM-037 Hydraulic Helm Pump
The Pro Marine 350-HELM-037 Hydraulic Helm Pump is a 37cc hydraulic steering helm designed for smooth, responsive steering control on high-horsepower outboard boats.
This Pro Marine helm is designed for the 350-HSTEER system and is compatible with many standard hydraulic steering systems, including Pro Marine, SeaStar®, Uflex®, and other similar front-mount hydraulic steering setups.
What a 37cc Helm Pump Does
The helm pump creates the hydraulic pressure that moves fluid through the steering hoses and into the steering cylinder. When you turn the wheel, the helm controls how much fluid is moved through the system, which directly affects steering feel and wheel turns lock-to-lock.
A 37cc helm moves more fluid per steering wheel turn than smaller 25cc or 30cc helms, which can create quicker steering response and fewer turns lock-to-lock when matched with the correct hydraulic steering cylinder.

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.
