Hynautic 3-Line Heavy Duty Hydraulic Steering System:

Boat Steer offers New and Remanufactured rugged 3-line Hynautic SeaStar Heavy Duty steering systems for most work and pleasure vessels up to 70 feet; Featuring Hynuatic Helm Pumps, Controls, Reservoirs, Steering Cylinders and Relief Valves.

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.
