output
Type 2 (for vessels
with a maximum
displacement of
22,000 Kg)
ACU-400 30 A Mechanical hydraulic linear drives
Designed for larger mechanically-steered vessels
over 20,000 kg, hydraulic linear drives consist of
a reversing pump, reservoir and hydraulic ram.
A hydraulic linear drive unit connects to the
rudder stock via an independent tiller arm.
Accessory fittings from your steering system
manufacturer may be required. The vessel’s
steering system must be capable of being
back-driven from the rudder.
Correct drive selection depends on the maximum
displacement of your vessel. Additionally, both
the vessel’s fitting structure and the tiller arm (or
rudder quadrant) must be able to cope with the
peak levels of thrust generated by the hydraulic
linear drive. For peak thrust data, refer to the
technical specification section of the Hydraulic
Linear Drive installation instructions.
Type 3 (for vessels
with a maximum
displacement of
35,000 Kg)
ACU-400 30 A
Type 1 (for vessels
with a maximum
displacement of
11,000 Kg)
ACU-200
15 A
Type 2 Short
(for vessels with
a maximum
displacement of
15,000 Kg)
ACU-400 30 A
Mechanical linear drives
Used in sailing vessels, the mechanical linear
drive moves the rudder directly by pushing the
tiller arm or a rudder quadrant.
Correct drive selection depends on the maximum
displacement of your vessel.
Type 2 Long
(for vessels with
a maximum
displacement of
20,000 Kg)
ACU-400 30 A
Type 1 (for vessels
with a maximum
displacement of
11,000 Kg)
ACU-200 15 A Mechanical rotary drives
Designed for power and sailing vessel systems
that can be driven from the helm position through
a chain and sprocket e.g. cable and rod.
Optional drive sprockets and modification to the
steering chain may be required.
Correct drive selection depends on the maximum
displacement of your vessel.
Type 2 (for vessels
with a maximum
displacement of
20,000 Kg)
ACU-400 30 A
Universal stern drive
For use with inboard / outboard (I/O) vessels with

Wheel drive — Power (Sport Drive)
Designed for smaller power vessels featuring a
steering system that can be driven directly from
the helm position.

mechanically
steered vessels
with a maximum
displacement
of 2,000 Kg),
or hydraulically
steered vessels
with a maximum
displacement of
3,181 Kg)
