25cc Hydraulic Steering Helm Pump
Pro Marine 350-HELM-025 Hydraulic Helm Pump
The Pro Marine 350-HELM-025 Hydraulic Helm Pump is a 25cc hydraulic steering helm designed for smooth, controlled steering response on modern outboard boats.
This helm is compatible with many standard hydraulic steering systems, including Pro Marine, SeaStar®, Uflex®, and other similar front-mount hydraulic steering setups.
What a Hydraulic Helm Pump Does
The helm pump is the core component of a hydraulic steering system. When the steering wheel is turned, the helm creates hydraulic pressure that moves fluid through the hoses and steering cylinder to turn the engine.
A properly matched helm pump helps provide predictable steering feel, reduced steering effort, and smooth handling at both low and high speeds.

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.
