HYNAUTIC 3-LINE HEAVY DUTY
HYDRAULIC STEERING SYSTEM:
SeaStar offers rugged 3-line Hynautic Heavy Duty
steering systems for most work and pleasure
vessels up to 70 feet.
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:
Low friction heavy duty hydraulic steering.
Helm/cylinder combinations for most inboards.
Marine grade materials.
Heavy duty helms available in three displacements,
to accommodate most applications and user
preferences.
Helms available with 1” straight shaft or
3/4” tapered. Mount facing any direction.
Quick air purge relief valve.
Fluid fill at remote reservoir.
Heavy duty brass cylinders. Two-axis articulation.
Easy installation for single or dual rudder vessels.
Meets or exceeds applicable standards.
Accepts most steering wheels.
