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.

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.
