IMPORTANT USER PRECAUTIONS AND PROCEDURES
- Please take time to acquaint yourself with the Power steering system components, operation
characteristics and safety features.
- Should the helm pump warning light illuminate or the alarm sound, immediately reduce engine power
to idle and go to the helm position with hydraulic back up (Lower helm on Flybridge boat).
When carrying out any servicing work on the Power Steering System or removal of the systems
Oil Tank Filler Cap release the system pressure.
(Invert the air pressure valve dust cover and press it against the top of the pressure valve)
- The power steering system can have two types of helm pumps installed - with or without hydraulic
backup.
- The system will shut down immediately in the event of an unexpected major component failure related
to the safe operation of the system. Oil or electric motor overheat conditions will activate the helm
pump warning light and alarm sounder, the system will monitor the alarm condition for a further two
minutes before system shut down. If the alarm condition is resolved within 2 minutes the system will
continue to function normally.
- In the event of system shut down, the helm pump with hydraulic back up function will become the
only operational helm (the electric only helm unit will not function) the steering system will function as
normal but with an increased number of wheel turns accompanied by a heavier wheel feel.
Do not continue to drive the boat at high speeds using the back up system.
Cylinder bypass:
To centralize the rudders, release valve locknut, open valve NV3 & NV4 (turn ccw
until stop).The cylinder is now free and the rudders can be centralized. Return NV3
and NV4 to original closed position (cw until stop) and tighten valve locknut
- immediately reduce engine
power to idle, and go to the
helm position with hydraulic
backup!
IN THE EVENT OF SHUTDOWN

The Power steering system comprises four main components.
1) The System Unit, consists of the Electronic Control Unit (ECU), an Oil lter and a
Valve Block integrated with the Oil Tank (Reservoir).
2) A Hydraulic Pump Unit, driven by an attached 24volt D.C. electric motor.
3) 2 x Helm Pumps
4) Hydraulic Cylinder(s)
The lower (primary) steering position helm has two functions:
a) It contains electronic sensors which transmit a signal to the ECU for normal Steering
operation.
b) It acts as a Hydraulic Helm Pump (back-up) in the event of an ECU system shut
down (NB, The number of wheel turns will increase from stop to stop during back up
mode).
The upper/ybridge helm has electronic sensors that pulses signals to the ECU for
normal Steering operation.
Both helms have a built in warning LED (Red). This will illuminate during an alarm
condition.

System Unit/Servo Pump installation
- Locate a suitable position to install the System Unit and Servo Pump Unit. Make sure that the selected
mounting position is adequate to support the system unit (approx 25 kg) and servo pump (approx. 10 kg)
- Mount the system unit and servo pump.
- Clean and ush all hoses. Use plastic caps or tape to seal the hose ends before the hoses are installed.
- When routing the hoses, avoid restrictions, hot spots, sharp edges and tight bends (Rmin = 130 mm
for 3/8” hose and 180 mm for ½” hose). Secure hoses with appropriate fastening devices to avoid
cha󰀩ng.
Hose installation
- Connect the servo pump hydraulic inlet/suction hose to hydraulic port S on the system unit. Connect
servo pump hydraulic outlet/pressure hose to hydraulic port P (lter) on system unit. Please refer to
drawing on page 8 for hydraulic port layout on the system unit.
- The Hoses can be connected either vertically or horizontally into the helm pump
(see helm pump description)
- Connect the hoses to the helm pump and the cylinder according to drawing on page 8 and 12.
- Connect the cooling water inlet/outlet hoses to the engine cooling system. Ensure that the hoses are
installed in accordance with this manuals paragraph “Hose Installation”.
Hose connecting
- Connect the temperature sensor leads to the system unit (external contacts). Connect the power leads
from (B-,P-) to Servo Pump (-), and (P+) on system unit external relay to (+) on Servo Pump.
- Connect battery power (24V DC) to the System Unit power terminals (positive cable to (B+) terminal
and negative to (B-) terminal & torque load to 17Nm)
- A 50Amp fuse must be installed in proximity of the batteries on the positive cable run, to protect the
system from damage from possible short circuiting.
For schematic drawings , see page 15 (Twin helm) & page 16 (Single helm).
- Connect the “Motor On” and Pilot Signal electrical looms to the external terminal block mounted on the
System Unit.

- The Cylinder must be mounted on a solid, rigid surface, either directly to the hull, or using an suitable
bracket.
- The Cylinder should be angled parallel to the transom (or to the tie bar on dual rudder installations),
when the rudder is at one of its end stops.
Ensure the cylinder stroke has been set to half full travel when the rudders are “dead ahead” , this
ensures equal stroke in both directions. - The cylinder must be installed in a position where the stroke
will be equal in both directions
- Secure the cylinder mounting foot with bolts, washers and Locknuts (i.e. Nyloc).
- It is important that the cylinder mounting foot is installed 90 degrees to the tiller arm, when the rudder
is in its centre position.
- Connect the cylinders rod end to the tiller arm using the correct sized bolt.
- Tighten the bolt.
- Connect the hydraulic hoses to the cylinder referring to schematics on page 9 and 14.

- Ensure there is adequate space to install the Helm Pump, Steering Wheel, associated looms and
hoses. Check they do not interfere with cables, wires or other components (See the helm pump
dimensions)
- Cut a hole (Ø121 mm), and drill the four 7 mm (5/16”) screw holes in accordance with the
dimensioned drawing.
- Fit the helm ttings and connect the hydraulic hoses referring to the diagram on page 12.
- Secure the helm pump using the washer and nuts (6mm).
- Apply a thin layer of grease on the helm pump shaft & t the steering wheel.
Connect signal and alarm cables. Refer to page 15 (Twin helm boats) and page 16 (Single helm boats).
Secure and fasten helm unit wiring to avoid wire and connector tension sharp obstacles and cha󰀩ng.
NOTE: Ensure “dummy” plug is tted to the Helm B port on single helm boats.
