HYDRAULIC STEERINGS
HYDRAULIC STEERING SYSTEMS
COMPOSITION AND WORKING PRINCIPLE
In order to get the best control with the minimum effort, the
steering system must match the specific vessel’s requirements.
A standard steering system in its basic composition is composed
by three major elements such as:
- hydraulic helm pump (1) of the axial piston type, which pumps
oil into the system each time the steering wheel is turned. The
pump is provided with a non return (lock) valve, to prevent any
uncontrolled movement of the rudder, and with a relief valve
to protect the steering system from any sudden and excessive
increase in pressure;
- hydraulic cylinder (2) is the real rudder actuator and determines
the power of the system. It is therefore important to select the
right cylinder model for the required torque (see page 27-44-66
for cylinder selection).
The pump and the cylinder are connected together by means of:
- rigid or flexible hoses (3) suitable for hydraulic applications
and sized according to the pump displacement. The rigid
piping system guarantees the best steering performance. A
flexible hose system can be used for rudder torque not higher
than 290 Kg/m (24.675 lb.in.).
To satisfy different needs, or adapt to specific solutions, this
basic configuration can be integrated with many other steering
components such as:
- hydraulic helm pumps for additional control stations (4);
- auto-pilot power units (5) are available in a wide range of
displacements and they can be combined with different steering
cylinders with a capacity of up to 3900 cc;
- valves and accessories (6) (see section “steering accessories”
from page 75).
The working principle of the basic steering system is very
simple:
A. By turning the steering wheel in one direction oil flow goes
from the helm pump to the steering cylinder.
B. This flow, which enters the cylinder, moves the piston, as well
as the rod connected to the tiller arm, in order to allow the
rudder to rotate.
C. Oil displaced from the opposite side of the cylinder flows back
to the helm pump.
D. By rotating the rudder in the opposite direction, simply turn
the helm pump the other way.
Note: in case of dual station, the oil cap of the pilot house shall be closed. If a power unit with automatic filling is installed both caps shall
be closed.

5. Auto-pilot power unit
The steering system determines boat maneuverability, ease of
control and reliability. Model choice and configuration will be
based on boat’s requirements and user’s needs.
Below is a list of the necessary steps to select the most suitable
system, either for boats equipped with outboard engines (A),
or for boats equipped with inboard engines (B). The following
pages provide customers with a range of steering components
and an Order Guide helps in the selection and suggests how to
size them.
A.
BOATS EQUIPPED WITH OUTBOARD ENGINES
1.
2.
Determine the number of outboard engines the boat has;
Determine the total engines power (i.e.: horsepower)
reminding that:
- if there are two engines with the same rotation direction
you need to add their powers;
- if there are two counter-rotating engines, you need to
consider the one engine power.
Example:
no. 1 engine of 300 Hp
total power 300 Hp
no. 2 engine of 150 Hp - same rotation direction
total power 300 Hp
no. 1 engine of 300 Hp - opposite rotation direction
total power 150 Hp
B. BOATS EQUIPPED WITH RUDDERS WHOSE MAX speed is
below 28 knots
1.
Calculate the required rudder torque (i.e.: Kgm or lb.in.)
according to the formula below. Bear in mind that the max
rudder torque of a boat depends on:
- boat max speed;
- rudder’s dimensions and shape;
- rudder compensation surface.
2. Determine the number of rudders in order to obtain the total
rudder torque.
Note: an important factor for the choice of the steering cylinder is
the type of hull (i.e.: planing or displacement) as it can influence
the vessel speed:
•
planing hull: max speed > 18 knots
•
displacement hull: max speed < 18 knots.
HYDRAULIC STEERINGS
HOW TO SELECT THE SUITABLE SYSTEM
Once the rudder torque has been calculated and the most suitable
steering cylinder has been selected, you need to determine the
size of the hydraulic helm pump, whose choice depends on the
following options:
A.
total number of wheel turns lock-to-lock (*);
B.
number of the control stations;
C. helm pump mounting configuration (frontal, intermediate,
rear or tilt mounting).
(*) Note: the total number of wheel turns lock-to-lock depends
on cylinder volume and helm displacement (divide the cylinder
volume by the helm pump displacement).
The necessary effort on the steering wheel is inversely proportional
to the total number of wheel turns lock-to-lock. Therefore:
- less wheel turns lock-to-lock result in more wheel effort on
the steering wheel;
- more wheel turns lock-to-lock result in less wheel effort on
the steering wheel.
ATTENTION! In case a helm pump with a higher displacement is
chosen, to decrease the total wheel turns lock-to-lock (within the
limitations indicated on the tables), you need to install a wheel
with a bigger diameter.
Formula for rudder torque calculation
for each rudder with an angle of 35°
Example:
a = rudder height in meters
b = rudder beam in meters
c = compensation distance in meters
d = arm = distance between the rudder axis
and pressure point
S = force
V = max speed in knots
A = total area in square meters=(axb)
a = 1,10 mt
b = 0,65 mt
c = 0,21 mt
V = 18 knots
d = (0,372 x 0,65) – 0,21 = 0,03
A = 1,10x0,65 = 0,71 mt2
S = 8,16 x 324 x 0,71 = 1.877,12 Kg
Mt = 1.877,12 x 0,03 = 56,31 Kgm
d = (0,372 x b) – c
S = 8,16 x V2 x A
Note: in case the vessel is equipped with two
rudders the total torque will be:
Mt = rudder torque in Kgm = S x d
Mt = 2 x 56,31 = 112,62 Kgm

HELM PUMPS
HELM PUMPS
A range of models in different displacements, configurations
and mounting options: a compact design with minimal helm
protrusion is one of the main features of this axial-piston pump.
Pumps are made of a high strength cast aluminum housing, that
is corrosion and abrasion resistant, and supplied with a lock valve,
which prevents any possible rudder feedback, while a relief valve
protects the steering components from over-pressure.
BCS helms are available in different mounting configurations:
the BASIC version, which is normally mounted outside on the
dash surface and with the steering shaft perpendicular to it, can
be combined with different mounting kits allowing the helm
protrusion to be reduced or even disappear behind the dash.
A SPORT TILT mechanism is available for a more comfortable
driving position (mounting angles other than 90 degrees).

OUTBOARD CYLINDERS
OUTBOARD CYLINDERS
FRONT MOUNTING
Reliability, quality and comfort.
Outboard steering can be adapted to the different mounting
configurations to cover any outboard application: this is the best
alternative for mechanical steering.
Suitable for single and multiple outboards up to 300 hp (600 hp
with combined counter-rotating engines), the outboard steering
is the ideal solution for runabouts, cruisers, and inflatables,
with either single or dual engine; they can also be used on
work, commercial or rescue boats, which normally require high
performances in severe service conditions.
SINGLE STATION
Built with high-quality materials, suitable to work in a marine
environment, compact design; the outboard steering cylinders
are suitable for most splash-well configurations.
The balanced front mounting cylinders allow the engine full and
free movement with minimum dimensions.
They can be combined with a wide range of accessories, such
as helm pumps, hoses in the necessary length, inch fittings and
hydraulic oil for a complete steering package.
DUAL STATION
Main features
Elegant and compact design that fits most splashwells
Hard chromed stainless steel piston rod
Balanced frontal mounting cylinder
Suitable for single and twin engine applications
Suitable for outboards up to 150 hp for the model OB-108 and
300 hp for the model OB-133 (600 hp if combined with counterrotating outboard engines) with a max speed of 60 kts
Combined with BCS helms, tubing, fittings and oil provides
a complete package of easy installation
Meets ABYC standards
approved
18
SIDE MOUNTING
The side mounting outboard cylinder represents the best
alternative to either mechanical steering or frontal mounting
cylinder, especially where the splashwell is not very deep.
It is suitable for outboard engines up to 300 hp (600 hp with
SINGLE STATION
combined counter-rotating outboards) for a max. speed of 60
kts. It can be combined with the steering helms (inch tubing
and fittings, hydraulic oil) for a complete package of easy
installation.

INBOARD STEERINGS
INBOARD STEERING SYSTEMS
The steering system is of crucial importance to ensure the best
boat maneuverability. Therefore, it is very important to choose the
model and configuration that best satisfy the boat requirements
and the user’s needs.
Please, see at pages 8-9 the guide for system selection and the
calculation of the max rudder torque, while the following pages
help in the selection of steering components.
For any questions, please contact the Twin Disc Technical Dept.
Precision and high quality materials are the main features of every
component of the BCS inboard steerings. Specific certificates
are available on request from the major classification bodies,
such as RINA, American Bureau of Shipping, Lloyd’s Register
of Shipping, Bureau Veritas, etc.
Inboard cylinders are available either in anodized aluminum
or brass versions. The piston rod is made of stainless steel to
ensure a longer, trouble-free life and to prevent rust or corrosion.
The ball joint is easily available in the most popular sizes. The
cylinder base moves both horizontally, to follow the complete
cylinder arch, and vertically, to follow and adapt to any excursion
of the tiller arm.
Every cylinder is supplied with Tee fittings provided with bleeders
and with all the connection fittings needed.
All the materials used for production of inboard steering cylinders
are suitable for applications in marine environment, even when
high level of salt is found.
Main features
Compact design
Available in a wide variety of volumes and strokes for an
extraordinary flexibility of applications
Provided with bleeders
Piston rod in stainless steel
Base moving either horizontally or vertically
High resistance to corrosion
Built according to ABYC standards

WARNING! The above suggestions shall be intended as indicative. To check the proper application the required max torque must be
calculated. If the required information is not available please contact our authorized dealer or service center and submit boat length, maximum
speed and rudder dimensions.
WARNING! For displacement boats, hull speed normally does not exceed 18 knots. For planing boats, the above steering systems are suggested
for boat speeds under 30 knots.

Twin Disc has developed a complete BCS line of heavy duty
steering components specifically for fishing or commercial boats
where work loads are havier and therefore we need a better
performance.
The complete range includes several models of helm pumps,
built with materials and techniques to be extremely robust, and
hydraulic cylinders, designed to satisfy the highest requirements
of reliability and long, trouble-free service.
There is also a selection of steering accessories easy to install
which complete the system. These make it safe (even in severe
service conditions) for the user to maintain control with the
maximum steering comfort.
Every component of this range is built and tested to meet the
toughest tests and satisfy the strictest standards of international
Survey Authorities such as RINA, Lloyd’s Register of Shipping,
American Bureau of Shipping, Bureau Veritas, etc.; these
organizations can also release specific certificates on request.
Heavy duty helm pumps
The heavy duty helm pumps are available in displacements from
63 cc, 89 cc, 105 cc, 151cc to 191cc. The 63 cc and 89 cc helm
pumps are also available with or without an extra oil tank.
In the single station steering system we suggest to install the
helm pump with extra oil tank, while with a dual station system
we suggest to install a classic helm pump on the lower station
and a helm pump with extra tank on the upper station.
The 105 cc, 151 cc and 191 cc helm pumps are all provided with
extra oil tank. The helm body is made of aluminum and the shaft
is made of stainless steel. High resistance seals are tested for long
life and heavy working cycles. Every pump is painted to withstand
even highly saline marine environments.

HEAVY DUTY INBOARD STEERING SYSTEMS
This series of helm pumps are not provided with built-in non
return and relief valves; so, these accessories shall be selected
and ordered separately to complete the steering system. In
addition the fittings kit is available in several sizes to satisfy the
different mounting configurations. They shall be selected and
ordered separately (see page 80).
Heavy duty cylinders
All heavy duty inboard cylinders are built with stainless steel
piston rod for high corrosion resistance.
The cylinder body is painted with paints suitable to work in a
marine environment. Ball joints are available in the most popular
sizes for the market and a stainless steel version can be supplied
on request. The cylinder base can adjust either horizontally, to
follow the complete arc of the cylinder, or vertically, in order to
adapt to any tiller excursion. Each cylinder is provided with Tee
fittings with bleeders as well as the necessary fittings for hose
connection.

POWER ASSISTED
INBOARD STEERINGS
POWER-ASSISTED INBOARD STEERING SYSTEM
Cruising towards the horizon of innovation, reliability and comfort
with the BCS power-assisted steering.
A prompt responsiveness and total control with just 3,5 wheel
turns lock-to-lock even at high speeds (over 28 Knots).
The compact design and the reduced number of components
(3 vs. 6-7 in other brands) allows the system to be easy to install
and service.
BCS power-assisted steering assures maximum comfort, minimum
effort, total efficiency in any sea condition.
The system.
The hydraulic helm pump is available in all displacements and
mounting configurations (see helm pump section from page 11
for the model selection).
Simple design with reduced dimensions for the steering cylinder, which are available either in anodized aluminum body (for
applications up to 45’), or in a brass body for heavier applications,
has the servo cylinder mounted directly to the main cylinder.
The BCS power-assisted steering is completely independent from
the vessel’s main engines and all necessary power is provided by a
single electro-hydraulic power unit.
The system has all the necessary valves for the servo system in
order to ensure safe steering (non return valves, relief valves
etc.). It also includes an interface for the auto-pilot and a
special device for the system automatic filling (see description of
the working principle for this device at the section “Auto-pilot power
units with automatic filling” page 54).
In order to ensure the best safety and total boat control in emergency
conditions, the BCS steering system automatically turns into a
manual system if there is any problem with the power unit.
Main features of the power-assisted steering system
Totally independent from the vessel propulsion system
Effortless navigation comfort in any condition
High quality, safety and reliability
Innovative concept and working principle
3 elements of the basic system vs. 6-7 elements in other
brands
Strong reduction of installation time (over 30% in comparison
with competitors steering)
Prompt responsiveness and total control in just 3.5 turns
lock-to-lock (this number can be varied)
Cooling system is not necessary
Supplied with interface for the auto-pilot
Special device for automatic filling of the system
Bleeding procedure easy and fast
Steering helm pump available in 5 displacements and 4
mounting configurations
Provided with automatic manual back-up steering
Simplified service and repair procedures (the system is not
pressurized)
Limited number of spare parts
Helm pumps and cylinders meet ABYC standards and are
approved
Helm pumps are NMMA Type Approved
60
The power-assisted steering is totally independent: the electrohydraulic power unit provides all the necessary power.
The steering system consists of an axial piston helm pump and
a power assisted cylinder, which has the servo cylinder mounted
on its body.
4. Oil displaced from the opposite side of the main cylinder flows
back to the helm pump.
1. By turning the steering wheel, an oil flow is sent from the helm
pump to the small servo cylinder mounted on the main one.
In case of emergency.
In case of electrical failure (i.e.: power unit cannot be turned on or is
out of order), by turning the helm pump oil flows automatically into
the main cylinder which then allows rudder to rotate. The powerassisted steering automatically becomes a manual hydraulic backup system with no need for switching anything or open/close any
by-pass.
2. This flow enters the cylinder and makes the piston move.
The pressure resulting from this movement is used to open a
distributor placed on the electro-hydraulic power unit.
5. To rotate the rudder in the opposite direction, simply turn the
helm pump the other way.
POWER ASSISTED
INBOARD STEERINGS
WORKING PRINCIPLE
3. As the distributor opens, an oil flow reaches the main cylinder
moving the piston as well as the rod connected to the tiller arm.
This causes the rudder to rotate.
CYLINDERS
The power-assisted steering cylinders are available with anodized
aluminum body (for applications up to 45’), or with a brass body
(for applications over 45’).
The small servo cylinder is mounted directly to the main
cylinder. This results in an extremely simple design with reduced
dimensions for an easy installation in very narrow spaces.
The piston rod is made of stainless steel for both the servo and
main cylinders allowing longer life and higher resistance to rust
and corrosion.
The standard dimensions of ball joints can be easily ordered and
can be supplied in stainless steel upon request.
The cylinder base can be adjusted either horizontally, to follow the
complete arc of the cylinder, or vertically, in order to be adapted to
any tiller extension.
Every cylinder is supplied with Tee fittings with bleeders as well as
the necessary fittings for hose connection.
All cylinders are built with materials suitable for application in marine
environment, where there is high level of salinity.
In case of particularly difficult environment conditions, we recommend
the use of stainless steel ball joints and fittings.
Main features of the power-assisted cylinders
Compact design with reduced dimensions
Servo cylinder integrally fixed to the main one
Available in a wide variety of volumes and strokes for
application flexibility
Provided with bleeders
Available with anodized aluminum or bronze body

POWER-ASSISTED ELECTRO-HYDRAULIC POWER UNITS
The BCS power-assisted electro-hydraulic power unit ensures
the best performance of the steering system: it guarantees all
the power necessary to the steering system and is completely
independent from the boat’s main engines.
Composition.
Extremely compact, it is composed of:
- a hard plastic tank, allowing the oil level to be easily checked;
- an electric motor;
- a hydraulic pump;
- a filter group;
- all necessary valves for both the steering operation and safety
(non return valves, relief valves, servo-control groups, pressure
adjusters, etc.).
This power unit is provided with:
- an interface for the auto-pilot;
- a special device for automatic filling of the system makes the
bleeding procedure easy and fast (more details at page 55 “Autopilot power units with automatic filling”);
- a speed adjuster, which can be adapted to any auto-pilot
manufacturer’s requirements.
The servo-control power unit can be excluded from the steering
system at any time by pressing the red button mounted on the unit
top. This immediately converts the system into a manual steering
system (please, also see the steering working principle on page 61).

ø12 mm (0,47”)
20 mm MAX (0,78”)
In all those cases where the helm pump mounting configuration
does not allow easy access to the filling cap, which is placed on
the helm top, (i.e. rear mounting or tilt mounting) a filling kit
should be purchased. This kit is directly screwed on the helm cap
in order to move the filling point to a new one which is accessed
more easily by means of a hose prolongation.
