SeaStar HH6490-4 PRO Sport Plus Tilt 2.0 Boat Hydraulic Helm Pump

The Dometic SeaStar PRO outboard steering helms (HH64904) 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.
