Seastar Hh5271 Hydraulic Steering Helm 1.7 Ratio To 500Hp

Experience responsive helm control with this high-performance hydraulic steering system. 

Engineered for vessels up to 500hp, the Seastar HH5271 delivers smooth, effortless directional command through its precision 1.7:1 turn ratio. Built for serious boaters who demand reliability and confidence at the wheel.

The Dometic SeaStar® Helm Pump is an axial piston pump. Every load bearing point within the helm pump runs on either a roller or ball bearing race for super low friction, smooth, positive steering. It has a built-in lock valve to prevent the steering load from feeding back to the driver. The lock valve will not allow the rudder or drive unit to move until you apply load by turning the steering wheel. The lock valve section of the helm also includes a relief valve. This relief valve provides over pressure protection for mechanical components, hydraulic hoses and fittings.
