SeaStar Solutions H-40 Series Heavy Duty Hynautic Helm Assembly

SeaStar H-20 Series Heavy Duty Hynautic Helms are for use with SeaStar's rugged 3-line Hynautic steering systems. These heavy duty helms combine one or two bi-directional axial piston pumps with pilot check and make-up check valving. The result is a unit which prevents rudder feedback, is very efficient (even at low RPM), and is immediately adaptable to multi-station use. A wide choice of helm displacements and cylinder configurations make it easy to spec a system which can handle a variety of large boat performance requirements and accommodate most user preferences.

Features:

  • Heavy-duty helm
  • Available in different displacements to accommodate most applications
  • Available with 1" straight shaft or 3/4" tapered
  • Made with marine-grade materials
  • Meets or exceeds applicable requirements
  • Adaptable to multi-station use

Max steering wheel diameter: 47"
