SeaStar HH5779-4 PRO Front Mount 1.7 Marine Hydraulic Helm Pump

The Dometic SeaStar PRO outboard steering helms (HH5779-4) and cylinders are suited for critical high speed, single powered outboard boats, like bass, flats, combo race/ski and other performance orientated boats capable of speeds in excess of 60mph. Designed for the performance boater, Dometic SeaStar Pro is the ultimate steering system for high-speed single engine outboards.

Important Update: Seastar Helm Update to -4

The latest series of helms has been redesigned to provide a better experience for the vessel operator:

• More durable check valves, making the entire steering system more resilient to the rigors of trailering.
