WARNING
This Autopilot will automatically steer your vessel, however, it is only an aid to
navigation. Its performance can be affected by many factors including
equipment failure, environmental conditions and improper handling or use.
This system does not reduce your responsibility for the control of the vessel
when underway. You must always be in a position to monitor the course,
supervise the Autopilot, and resume manual control if the need to do so
arises.
Whenever underway, your vessel must be under the control of
a qualified and alert person.

PRODUCT DESCRIPTION
SI-TEX SP-70 or SP-80 Autopilots are
reliable, accurate and easy to use aids to
navigation. They feature four operating
modes, watertight design, and built-in
navigation interface.
The SP-70/SP-80 contains a program called
Ghost Rudder. Should the Rudder Feedback
fail, the Autopilot will use its memory of the
rudder movement to calculate new rudder
positions. The Ghost Rudder program will not
allow the Autopilot to steer as well as it can
with the Rudder Feedback. It will allow the
Autopilot to be used until repairs can be
made to the Rudder Feedback.
The 4 operating modes are:
• STANDBY MODE allows manual steering
while displaying compass information.
• POWER STEERING MODE features
push button steering control, and displays
compass or rudder information.
• PILOT MODE steers to a constant
heading.
• NAV MODE steers along a course line
when the SP-70 or SP-80 is connected to
an appropriate navigation device.
The design of the SP-70/SP-80 includes
many circuit protection devices such as;
reverse power connection protection, output
circuitry overload protection, protection
against overheating, protection against
computer failure or program error.
SPECIFICATIONS
Voltage: 10VDC - 40 VDC
Steering Outputs: 20 Amperes Maximum
In both PILOT and NAV Mode, pressing the
Red or Green Key allows use of the
Dodge/Course-change feature.
To steer a constant heading, the SP-70 or
SP-80
compares
compass
heading
information with the course heading that is
entered into memory. If the vessel is not on
the correct heading, the Autopilot calculates
the rudder position that will bring the vessel
onto the correct heading. The Autopilot uses
a drive unit to move the rudder. Information
from the Rotary Feedback or Outboard
Feedback is used to calculate new rudder
positions and to verify that the steering
system
has
followed
the
Autopilot
commands.

When steering along a course line, both
Autopilots use information from the compass
to monitor the heading. They also use
position information received in NMEA 0183
format from LORAN, GPS, or plotter. Using
both of these inputs, the SP-70/SP-80
calculates a course to steer and keeps the
vessel on the course line.

INSTALLATION INSTRUCTIONS
SI-TEX MARINE REVERSING PUMP
Part Nos. 20810016, 20810031, 20810018 & 20810035
GENERAL:
The reversing pump consists of a hydraulic pump and a motor. The pump is a piston type, driven
by a reversing permanent magnet motor. The pump is designed in such a way that it will keep oil
from returning through the pump when is not running or correcting. There is also a bleed-to tank to
allow the use of unbalanced cylinders. The pump is compatible with all hydraulic steering systems
including pressurized steering systems such as Hynautic.
SPILL VALVE
ADJUSTMENT
To adjust flow rate, loosen pump housing screws and turn pump housing. Clockwise will decrease
flow rate, anti-clockwise to increase flow rate.

***** IMPORTANT *****
If the system you purchased includes a reversing motor pumpset, it is important that you apply
and install this unit correctly. To ensure that you get the most from your purchase, read this
installation and instruction manual carefully. By following the step-by-step procedure and using
only basic tools and materials, you will find the installation easy to do.
Caution
This Pump is not waterproof and is therefore not warranted against water damage.
This Pump is not warranted against damage caused by improper installation.
If you are installing this pump on a Capilano or Syten steering system, you probably have
a 3-line steering system. Read the 3-line steering installation instructions carefully.

Planning
The pump can be mounted in any orientation
except with Port C facing downward. If Port
C is facing downward then air will not be able
to rise out of the pump and the pump will not
have a supply of oil.
Installation of the pump consists of:
• Finding a mounting location for the
pump
• Partially draining the steering system
There are two ways to connect the pump to
the steering system. The first is to leave the
system completely filled and be careful not to
spill hydraulic fluid. The second is to drain
the system of fluid completely before cutting
or opening any lines.
• Mounting and connecting the pump to
the existing steering lines
• Filling and
system.
bleeding
the
steering
If you follow the first method, remember that
when you disconnect or cut the steering
lines, there will be a constant slow discharge
of oil due to gravity draining the system.
Have a container ready to catch all excess
oil. Do not reuse any oil reclaimed from your
system.
A suitable mounting location for the pump
MUST:
• Be dry
• Be lower than at least one of the helm
pumps in the steering system
Draining your System
• Provide a solid mounting base
If you wish to follow the second method and
drain the system, use the following simple
procedure.
1. Have a large container, about 2 gallons,
ready.
2. Disconnect the delivery lines at a low
point, usually where the lines connect to
the steering cylinder.
3. Turn the wheel of the highest helm pump
in both directions until no more fluid
comes out of the lines.
4. Repeat the previous step on each lower
helm pump in turn.
• Be at least 4 feet (3.1 m) from the
vessel’s compass.
A mounting location for the pump SHOULD:
• Provide easy access to the pump
• Provide an easy connection point to
the steering system
• Minimize the length of the pump hoses
• Minimize the length of the wires to the
motor.
Types of Steering Systems
A typical mounting location would be in the
engine compartment or the steering console.
There are two general types of steering
systems, two-line systems, and three-line
systems. The pump connection to the
steering system is different for each type.
Separate instructions are supplied for both
types of steering systems.
You have a three-line system if the helm pump is a Capilano Model 250 or 275 (Made by
Teleflex), or if there is a Uniflow valve mounted close to the steering cylinder.
P/N 29010049 V1.2
15
You have a two-line system if you do not have the above components in your system.
CAUTION
CLEANLINESS must be maintained while making hydraulic connections. Contamination
introduced into the steering system fluid can cause steering components to malfunction, possibly
resulting in a loss of steering.
Before beginning to connect the pump to the steering system, review the following installation
hints:
• Cap or cover the ends of hoses with a
clean rag before pushing them
between bulkheads.
Do not place thread sealer on female pipe
threads.
• When tightening fittings into the pump
lockvalve, hold the lockvalve, not the
motor. That way, the lockvalve will not
twist out of alignment with the rest of
the pump.
• Wipe copper filings off freshly cut and
reamed copper tube. Do not blow the
filings off.
• Teflon based thread sealer, such as
'LOCTITE™ P.S.T.' must be used on
all male pipe threads. Do not place
thread sealer on the first two threads.
Do not use a tape-type thread sealer.
These can shred and enter the
steering system fluid.
• Connection of the pump lines is most
easily made at existing breaks in the
steering system lines. For example:
valves, t-joints and other fittings.
CAUTION
Opening your hydraulic steering system will introduce air into your steering system. This air will be
expelled if the steering system is bled properly. After you refill your system and during the "Set-up
Routine", your autopilot can be used for bleeding the air. Ensure that you follow the Compensating
Line installation instructions very carefully as all air is expelled through this line when bleeding your
system. If the Compensating Line does not prime properly and allow fluid to get to the autopilot
pump, the pump will not perform properly. The Compensating Line does not have to be a highpressure hose. In fact, even a clear hose can be used allowing for easy visual confirmation of proper
Compensating Line operation.

Hydraulic Connections For Two-Line Steering Systems
A simple schematic of the pump installation is shown below.
2 Line Steering System Installation
Delivery Lines:
Ports A and B in the diagram above are the input/output ports of the pump and must be
connected to the steering lines coming from the steering cylinder. It does not matter which
pump port is connected to which steering line.
Compensating Line:
In the above diagram Port C is the compensating or bleed line, and must be connected to the
steering system's reservoir. This connection can be made at: a helm pump; remote reservoir (if
there is one); the compensating line connecting two helm pumps; or the compensating line
connecting a helm pump to the remote reservoir. If the connection is being made directly to the
helm pump, ensure that the bleed line is connected to the LOWER helm bleed port.
The compensating line MUST have a gradual rise from the pump, to the connection, to the
steering system. This allows air to rise out of the pump, ensuring a constant supply of oil to the
pump.
INSTALLATION OF SHUT-OFF VALVES RECOMMENDED

Hydraulic Connections For Three-Line Steering Systems
A simple schematic of the pump installation is shown below.
3 Line Steering System Installation
Delivery Lines:
In the above diagram, Ports A and B are the input/output ports of the pump and must be
connected to the steering lines between the steering cylinder and the Uniflow valve. The
simplest method of doing this is to install a tee in each of the cylinder ports of the Uniflow valve
itself and connect to these tees. It does not matter which pump port is connected to which
steering line.
Compensating Line:
Port C is the compensating or bleed line and must be connected to the steering systems’
reservoir. This connection can be made at a helm pump; a remote reservoir (if there is one); the
return line connecting two helm pumps; or the return line between a pump and the Uniflow
valve. If the connection is being made directly to the helm pump, ensure that the bleed line is
connected to the LOWEST bleed port of the pump.
The connection MUST be at least six feet (1.83 m) from the Uniflow valve as shown above. If the
connection is too close to the Uniflow valve, the manual steering system may not work well.
The compensating line MUST have a gradual rise from the pump, to the connection, to the
steering system. This allows air to rise out of the pump, ensuring a constant supply of oil to the
pump.
INSTALLATION OF SHUT-OFF VALVES RECOMMENDED

Re-Fill And Bleed
After you have installed your Pump, refill and bleed your manual steering system according to the
manufacturer's directions. Any air, which is in the pump, will be expelled during the Set-up Routine.

INSTALLATION INSTRUCTIONS
SP-70 and SP-80 AUTOPILOTS
Planning
If you are going to use a sealant when
flush mounting the SP-80 Control Head,
be careful to not cover the small square
hole in the middle of the bottom side.
This hole must vent to atmosphere.
Caution
Using ordinary electric tools near water is
very dangerous. To minimize the dangers of
electric shock and personal injury, we
recommend using cordless rechargeable
tools or hand tools.
Do not mount the Processor near heat
sources, such as heat radiators, or over
engines. If you can, mount the Processor so
that the cooling fins are vertical.
Processor Location
Power Connection
Allow at least a foot or 30 cm of clearance on
either end of the Processor in the space
where it is to be located.
There is a 7.5 foot (2.3 metre) power cable
included with your SI-TEX SP-70/SP-80. We
recommend that you do not lengthen this
cable.
In choosing a location for your SI-TEX
SP-70/SP-80, remember that the Control Unit
Interconnection Cable or Number 1 Cable,
and the cable from the Compass to the
Processor should not be cut or lengthened.
Excess cable may be loosely coiled behind a
panel.
If you must extend the cable:
•
•
•
Number 1 Cable from the SP-70 Control Unit
Receptacle to the Processor is 10 feet long
(3.05 metres). Number 1 cable from the SP80 Control Unit to Processor is 25 feet long
(7.7 metres).
•
The cable from the Compass to the
Processor is 40 feet long (12.2 metres).
You will want to have the Control unit near
the steering station you use the most. On SP70’s try to position the Receptacle so that the
curly cord will also reach other convenient
locations such as the place that you use
when docking your vessel.
P/N 29010049 V1.2
21
Use the smallest extension length
possible.
Use no less than 10 A.W.G. (6mm2)
conductor. Splice and solder the joints.
The extension must be less than 10 feet
(3 metres).
Make the joints watertight by using heatshrink tubing and silicon, or some other
watertight covering.
Grounding
Compass Location
The Power Cable also contains a grounding
wire. Connecting this wire to a proper ground
(*see below) may reduce static on radios and
improve LORAN reception.
When choosing a location for the Compass,
try to locate it as close as possible to the
most stable spot on your boat. Usually this
spot will be close to the water line level, in the
middle of the boat and two-thirds towards the
stern from the bow.
Many different grounding connections could
be used:
1.
2.
3.
Do not install your Compass near wires or
devices carrying large electric currents such
as battery chargers, electric pumps, motors
or televisions.
If you have a small vessel, the
negative battery post can be used.
If you have several electronic
instruments,
each
could
be
individually attached to the battery
post. Do not connect one instrument
to another instrument and then to the
post.
If you have a ground plane for a radio
on your boat, connect the ground wire
to that ground plane.
Do not mount your Compass near any iron or
steel objects.
Tools
You will need the following tools to install
your SI-TEX Autopilot:
*A proper ground connection point must be at
the same voltage potential as battery
negative. Any voltage difference between
battery negative and the ground point may
indicate a problem and the ground wire
should not be used. Ensure that connection
wires are as short as possible and that
connections are clean.
SCREWDRIVER: One Phillips and one
medium slot screwdriver
WIRE CUTTERS: A pair of ordinary wire
cutters suitable for general work around your
house.
DRILL and a selection of DRILL BITS
SMALL ADJUSTABLE WRENCH
If you purchased a SP-70 or SP-80 with a
Rotary Rudder Feedback you may need one
stainless steel band clamp which is more
than large enough to fit around your rudder
post.
You may also wish to have a supply of tie
wraps for securing cable lengths and tools
specific to your own boat.
P/N 29010049 V1.2

SP-70 Receptacle Installation
The Receptacle is attached to the Number 1 cable. The diagram to the right shows the Receptacle
mounted in a panel.
Mount the receptacle
near your normal
steering position.
The curly cord on the
Control Unit lets you
move about 5 feet
away
from
the
Receptacle.
A stainless steel ring
is placed between
the bolt heads and
the
receptacle
flange.
Do not
attempt to seal the
receptacle by overtightening the bolts
as the ring will
deform
the
receptacle
and
interfere with plug
Cable 1 Receptacle Installation
insertion. A proper
caulking compound
or sealant should be used instead. The three bolts should only be tightened enough to compress
the lock-washers, no more. As the plug has a tight seal, and insertion into the receptacle may be
stiff, a lubricant has been included in your package.
Hole sizes:
Hole for receptacle:
0.825 inches or 21 mm in diameter.
Use the barrel of the Receptacle to mark holes for the flange.
Holes in the flange are for a number 6 (3mm) screw. You may wish to vary this size depending
upon the panel material.
Clip Installation
The Clip is used for mounting the Control Unit. The Clip is mounted with two number 10 (5mm)
screws or bolts.
The usual mounting location is on the dashboard within easy reach when you are steering your
vessel.
P/N 29010049 V1.2
23
Power Cable Installation
Fluxgate Compass Installation
The Power Cable is labelled with a "5".
Connect the Power Cable to a breaker
capable of supplying twenty Amperes.
CAUTION
Keep the breaker turned off or do not
connect the cable to the breaker.
Fluxgate Compass
Use the white wire for battery positive from
the breaker. Use the black wire for battery
negative. The green wire is a grounding wire.
The fluxgate compass must be correctly
positioned or it will not work.
Extending the cable is not recommended. If
you must extend it, see page 23 for
guidelines on proper extension techniques.
To correctly position the Fluxgate Compass,
mount it so that the surface with the cable
gland is up. On the top surface there is an
arrow labelled "bow". The arrow must point
in the same direction as the bow of your boat.
In cases where the compass is mounted on
a side wall, the bow line arrow may be ± 90
degrees out of alignment. Remove the four
top housing screws and rotate the housing ±
90 degrees. Warning: This unit comes
from the factory watertight. Be careful
with seals and “O” rings if you remove the
housing.
Route the supplied Cable to the Processor
location.
Initially, mount your Fluxgate Compass using
strong adhesive tape or some other
temporary, non-marking fastener. Coil any
excess cable at the Compass location rather
than at the Processor. It may be necessary
to relocate your compass after you have
done the "Set-up Procedure".

Mounting the Rudder Feedback
Rudder Feedback correctly installed to rudder post
In the diagram above notice that:
• the Rudder Feedback Arm is above the
cable entry gland;
• the Linkage sockets are on the top of the
ball joints. Do not hang the Linkage from
the ball joints.
Use the Rudder Feedback as a template to
drill holes in the mounting surface. If you
must drill new holes in the flange at the back
of the Rudder Feedback, drill the Rudder
Feedback flange first, and then use it as a
template to drill holes in the surface.
Mount the Rudder Feedback so that the
Rudder Feedback Arm and the Rudder Arm:
• are at the same height and
• separated by less than 24 in. (60.9 cm)
center to center, and
• each makes an angle of 90 degrees with
the Linkage.
Mount the Rudder Feedback using # 10 (5
mm) screws or bolts of suitable length.
To correctly align the Rudder Feedback and
the Rudder Arm, you may need to make a
mounting base for the Rudder Feedback.
Such a base must be firm. It should not flex
when the vessel is moving.

To
Assemble
Feedback Arm
the
Rudder
Loosen the adjustment block that keeps the
two pieces of the Rudder Feedback Linkage
from sliding.
Measure the approximate diameter of your
rudder post in inches.
Snap the Rudder Feedback Linkage onto the
two Brass Balls. Make sure to close the small
release clamps on each Plastic Socket.
The Rudder Arm has several holes drilled
through it. The holes are marked by numbers
on the top surface of the arm.
With the Rudder Feedback Arm directly
above the cable gland and the Rudder Arm
pointing straight ahead, tighten the adjusting
block.
Select the hole on the Rudder Arm marked
by a number equal to the diameter of your
rudder post measured in inches. (1 cm =
0.394 in.)
Caution
Bolt the Brass Ball Joint onto the Rudder Arm
using the selected hole. The ball of the Brass
Ball Joint must be on the same side of the
Rudder Arm as the numbers. Tighten the nut
and lock washer securely.
Carefully watch the Linkage while you move
the rudder through its full range of motion.
The Rudder Feedback and the Rudder
Feedback Linkage should move easily
without binding. The moving parts must not
contact any other objects. If there are any
problems, fix them now.
Attach the Rudder Post Arm to the rudder
post using a stainless steel band clamp. The
Brass Ball Joint must be on top. The Rudder
Post Arm must be at the same height as the
Rudder Follower.
The Rudder Post Arm must point straight
ahead when the rudder is in the straight
ahead steering position.
Run the Rudder Feedback Cable from the
Rudder Feedback to the space where the
Processor will be located. Place the Cable so
that it is protected from abrasion, stretching
and cutting.

Outboard Feedback Installation
If you have a Rotary Rudder Feedback, see the section titled, "Rotary Rudder Feedback".
Introduction:
The Outboard Feedback sends information
about the rudder or propeller position to the
SP-70 or SP-80.
The Outboard Feedback is provided with 30
feet (9.1 metres) of cable.
The Outboard Feedback can be used with
hydraulic cylinders from 1.25 to 2.25 inches.
(31.8 to 57.1 mm) in diameter. The cylinder
stroke cannot exceed 10.5 inches (266 mm).
The Outboard Feedback can be attached to
the hydraulic steering cylinder by using a
stainless steel band clamp. A stainless steel
bracket attaches one end of the Outboard
Feedback to the steering cylinder rod.
Outboard Feedback
Caution
The Outboard Feedback will be damaged if it is extended more than 10.5 inches. This damage will
not be covered by warranty.
If necessary, the extended length of the steering cylinder can be limited using corrosion-resistant
spacers as shown on page 36.

Mounting Hardware
Mount the Outboard Feedback so that it will not be damaged when the motor is tilted for trailering.
Installation
stainless steel band clamp. The clamp should
be positioned as close as possible to the tube
end where the cable exits.
The Outboard Feedback may be mounted
with the sliding rod facing either left or right.
Remove the nut from the end of the rod on
the hydraulic cylinder. Place the stainless
steel bracket over the threaded end of the rod
and replace the nut. Do not completely
tighten at this time.
Before you install the Feedback, move the
steering gear through its full range of motion
from one side to the other. Measure the
change in length, of the hydraulic steering
cylinder rod. If the rod extends or retracts
more than 10 in. (254 mm), make spacers to
limit the motion of the steering system as
shown on page 35.
Adjust the position of the Outboard Feedback
so that the end of the sliding rod is flush with
the Stainless Bracket. Screw the nut onto the
threaded rod at the end of the Outboard
Feedback.
Turn the motor so that it is centered between
the left and right limits of travel.
Use a tape measure or ruler to position the
Outboard Feedback rod so that it projects
5.25 in. (133 mm) from the body of the
Outboard Feedback.
Loosely clamp the Outboard Feedback to the
tube of the hydraulic cylinder using both
pieces of the two piece mount and the
P/N 29010049 V1.2
32
The Outboard Feedback should now be at
half its full extension and attached to the
outboard motor which is at the center
position.
Adjust the position of the Outboard Feedback
so that as nearly as possible it is parallel with
the hydraulic cylinder both horizontally and
vertically. Tighten the nuts and the stainless
steel band clamp securely.
Run the cable forward to the Processor
location. Choose a route for the cable so that
the minimum bend radius in the cable is at
least 4.2 in. (10.7 cm). This is especially
important in the motor well and other areas
where vibration is present.
Minimum Bend Radius
Complete the autopilot installation and
perform the Set-up Routine as described.
Maintenance
Keep the sliding rod clean. Wipe it occasionally so that dirt cannot enter the Linear Feedback. Use
a clean, soft rag.
After trailering your boat, it is very important to clean the sliding rod.

Connecting the ground
FUSE REPLACEMENT
In the picture above, the ground wire is the
green wire. It is connected to the bolt beside
the terminal sockets for the power
connection.
The Si-Tex Processor is protected against
reversed power connection by a fuse. The
fuse will probably not blow otherwise. If you
need to replace this fuse, check your power
supply for correct polarity.
The green wire is connected by removing
one of the nuts and the lock-washer from the
bolt. Place the connector on the end of the
green wire over the bolt. Replace the lock
washer. Replace the nut and tighten it
securely.
To replace the fuse:
1.
Turn off the power to the Processor.
2.
The other end of this wire should be
connected to the grounding point you have
chosen aboard your boat. See page 24 for
examples of possible grounding points.
Loosen the right side watertight glands.
Remove the end cap. Disconnect the
plugs.
3.
If you are assembling your Autopilot for the
first time, please go to the section titled,
"Mounting the Processor" on the next page.
Remove the 4 Phillips screws holding
the inner end cap. Remove the inner
end cap.
4.
Bend up the copper ground tabs so that
they are parallel to the body of the
Processor.

you still have an electrical problem on
your boat, or the Autopilot needs repair.
The Installation of the SP-70 or SP-80 is
complete. You are now ready to begin the
"Set-up Routine".
Mounting the Processor
Once you have completed and checked the
wiring, you are ready to mount the Processor.
There are two ways this can be done,
depending on the amount of space you have.
The first method will usually be easier.
For ease of wiring, it is recommended that
the Processor be mounted horizontally
rather than vertically.
The first method is:
Plug the terminal strips into their correct
positions on the processor.
Attach the end pieces. Do not cut or crimp
any wires while tightening the screws.
Tighten the nuts on the watertight glands.
Tighten these nuts firmly with your hand. If
you must use a tool, be very careful. It is very
easy to damage the glands by using too
much force.

IMPORTANT
****
If you have installed a ComNav Marine reversing motor pump, a constant running pump or an
engine driven pump, there are several checks that must be done during the first several weeks of
usage in order to prevent poor or dangerous steering performance. During this period you must
check for air or leaks in your hydraulic system.
Residual air in your steering system
Following the initial installation and bleeding of your ComNav pump, some residual air may remain
suspended in the hydraulic fluid. During the first few weeks, this air will gradually bleed out through
the header tank or the highest helm pump and the oil level may go down. Check several times and
add more oil as required.
Leaking fittings or equipment
Following the initial installation and bleeding of your ComNav pump, continuously monitor the oil
level of the reservoir, or the highest helm pump in your steering system and add oil as required. If
this condition persists, it may be an indication of leakage in your steering system. Check all
hydraulic steering fittings and equipment for leakage.

PILOTING WITH THE SP-70 or SP-80 AUTOPILOT
Some vessels may not use all of the
Rudder & Counter-Rudder Response
settings.
This section will introduce you to your

operations step by step, you will find it's one
of the simplest things on your boat.
•
Four: Rudder Response settings.
Turn on the SI-TEX Autopilot by holding
down the Pilot Key for two seconds. The
autopilot will display “SP” first, then software
versions and last, vessel heading followed by
a “P”. You are now piloting with the SP-70 or
SP-80. To get manual command back, press
the Sby/Off Key momentarily.

Response setting.
PILOT MODE
Fast Boat Speed Setting
Steering Control Settings
The SI-TEX Autopilot has a very wide range
of steering control settings. There are:
Each Rudder Response setting controls the
steering in a very different way. The four
Rudder Response settings are:
•
•
•
•
Some vessels always respond quickly to a
small movement of the steering wheel
regardless of the boat speed. These boats
might get the best steering control by always
using the "fast" boat speed setting. When the
boat speed varies, change the sensitivity of
the "fast" Rudder Response by a few steps.
This might give you better steering
performance than using the "slow" boat
speed Rudder Response setting.
Slow Rudder Response
Slow Counter-Rudder Response
Fast Rudder Response

The 10 sensitivity steps are numbered zero to
nine. Zero is an active setting and does not
mean OFF.

Slow Boat Speed Setting
In this section, you will learn how to:
•
•
•
•
Some vessels always require large amounts
of steering wheel movement to start and stop
a turn. These might get the best steering
performance by using only the "slow" boat
speed Rudder Response setting for all
speeds. When the boat speed varies, change
the Sensitivity of the "slow" Rudder
Response by a few steps. This may be all
that is required.
Use your Autopilot to steer a compass
course.
Select between the “fast” and the “slow”
boat speed Rudder & Counter-Rudder
Response.
Select the correct sensitivity in each
Rudder & Counter-Rudder Response.
Use the features of your Autopilot.
After you have learned how to do this,
experiment with your boat to find the
combination of Rudder & Counter-Rudder
Response settings that work the best for you.
P/N 29010049 V1.2
What is Good Steering Control?
When your SI-TEX Autopilot is working
properly, it will steer your vessel in a straight
line. The boat will not wander back and forth
across the course line nor make any sudden
turns unless you command it (refer to page
67).
59
Setting Slow Speed Rudder Response
OFF
If you wish to turn off the Autopilot, press and
hold the sby/Off Key for 2 seconds.
Immediately after pressing this key, you will
have manual vessel steering control.
It is best to set the slow speed Rudder
Response first. These adjustments are much
easier to do if the water is calm and there is
little wind.
At this point, you will have finished adjusting
your compass and exited the Set-up Routine.
Move your boat to an open area of water
away from docks and other boats.
With the Autopilot on, press the Set Key. For
a five second interval the display will read
either [FASt] (fast) or [SLOU] (slow). This is
the Rudder Response speed setting that your
Autopilot is currently using.
Your vessel may make several turns while
you are setting the Rudder Response. Make
sure that you and your passengers are
braced for unexpected movement.
If the display is reading [FASt], press the
Green Key during the five second interval to
change the display to [SLOU]. Your vessel is
now using the slow boat speed Rudder
Response settings.
Adjust your throttle so that your boat is
moving at a commonly used slow speed. If
you fish often, this could be your trolling
speed. Bring your boat onto a course.
Allow the Autopilot to steer your boat for
a few minutes, so you can measure its
performance. The pilot may move back
and forth across the desired course line.
Turn ON the SP-70 or SP-80 Autopilot. To
turn on the Autopilot, press the Pilot Key.
The Autopilot will fist display SP, then the
software version number. Finally, the present
course followed by a capital letter “P” will be
displayed. [xxxP]. The Autopilot will now
begin to steer the boat along the displayed
course. The autopilot is in PILOT MODE and
is steering by the compass.
This movement occurs when your rudder
sensitivity is too high or your counter rudder
sensitivity is set too low. The autopilot is
over-correcting for course errors (refer to
diagram on page 65).
To decrease the Rudder sensitivity:
Press the Set Key. The display will show
[SLOU] for five seconds. During this five
second interval, press the Set Key again and
the Autopilot will display the Rudder

you. If this new setting is still not suitable,
repeat the instructions above. Continue this
process until your vessel is steering well.
Turns and Changing Course
The vessel may also gradually fall off the
desired course line:
Press the Sby/Off Key briefly. The autopilot
is now in STANDBY MODE. This will be
indicated by the mark in the top right corner
of the display. [xxx’]
While you are travelling slowly, it is a good
time to practice using your SI-TEX Autopilot.

will change to show your new course.
To return to STANDBY MODE and manual
steering control, press the Sby/Off Key
briefly.
Dodge
In POWER STEER MODE, the rudder angle and
the rate of turn will increase as long as you
hold the Red or Green Key down. When you
release the key, your vessel will continue to
turn at a constant rate. To decrease the rate
of turn, or to go straight, press the other key.
To dodge around an object in the water,
press and hold either the Green or Red Key.
The letter at the right-hand side of the display
will change to a “d” [xxxd]. The course will
be displayed.
The course will change as long as you hold
down the Red or Green Key. The Autopilot
will turn your vessel to follow the changing
course. Your vessel will turn at a rate of 5º
per second in “slow” boat speed setting.
Each time you press the Red or Green Key:
• output indicators appear at the top of the
display and,
• the rudder angle is displayed for two
seconds.
After the key is released, the Autopilot will
return to its original course. The display will
again show the course with a capital P [xxxP]
on the right-hand side.
If you wish to always see the rudder angle,
press the Set Key. The display will be locked
on.
Large Course Change
To return to the compass heading display,
press the Set Key.
There are several ways to make large course
changes:

Adjusting Your Digital Rudder
Angle Indicator (RAI)
Offset
Many vessels always need the rudder
positioned to the right or left a small amount.
This slightly offset rudder position is needed
to correct for the turning effect of a single
propeller. To the driver, it feels that this
Offset Position is the straight-ahead position
or the 0-degree position.
The SP-70 & SP-80 also provide an
electronic Rudder Angle Indicator.
You can adjust the R.A.I. so that it accurately
reflects your rudder movements.
For this adjustment, you should have your
boat out on the water away from traffic lanes.
If you have power assisted steering, start with
your motor idling so that you can use your
power steering.
To avoid confusion, the RAI can be calibrated
so that it will show zero degrees when the
vessel is travelling straight ahead, even if the
rudder is slightly offset.
While travelling straight ahead at cruising
speed with the Autopilot in POWER STEER,
press the Flush Key. Press the Red and
Green Keys to adjust the RAI to show zero
degrees.
Press the Pilot Key to turn on the autopilot.
Briefly press the Sby/Off Key.
With the Autopilot in STANDBY, use manual
steering to move the steering gear from the
left mechanical limit to the right limit. Watch
the motor or rudder. Estimate in degrees the
size of the arc from left to right.
The Autopilot will return to its previous display
when you have finished.
This must be done manually, as the autopilot
will not move the steering gear so far that the
steering strikes a mechanical limit. The
Autopilot sets these electronic limits during
the Set-up Routine to save wear on your
steering system.
Press the Green Key once and then press
the Flush Key twice. The display now shows
the total degrees of travel of your steering
system. Press the Red and Green Keys to
adjust the number until it is the same as your
estimation of the actual arc.
A short interval after you have completed
your adjustment, the Autopilot will return to its
previous display.

Using Your Navigation Interface
To be safe, learn to use your Navigation
Interface at slow speeds, away from other
vessels.

Turn on the navigation device.
TO THE PRESENT HEADING USING COMPASS
INFORMATION.
Please remember that all SI-TEX SP-70 and
SP-80 Autopilots are tested at the factory, so
the first things to check are your wiring and
your navigation device. Read your owner’s
manual for the navigation device to make
sure that it is sending out NMEA 0183
language.
Also see the next section:
“Problem Solving”, for further help.
This could be a LORAN, GPS or plotter.
Give it time to find its position accurately and
turn off its warning indicators.
Enter a Waypoint into the navigation
device.
With some navigation devices, it is necessary
to tell them to send information to the
Autopilot.
If the Autopilot intermittently displays [F’dat]
(Faulty Data), then it is receiving a warning
signal from the navigation device.
With all navigation devices, make sure that it
is sending information in the NMEA 0183
format.
Caution
Look at the Control Unit display. Press
the Nav Key.
It is strongly recommended that you do not
continue to use the NAV MODE if [F’dat] is
displayed.
The autopilot is now in NAV MODE. The
Autopilot will display [xxxn}. The large lower
case “n” at the right side of the display shows
the Autopilot is in NAV MODE.
This signal indicates that the navigation
information may not be accurate. Check your
navigation device for warning indicators such
as a flashing light or message.
If the SI-TEX Autopilot receives usable data
from your navigation device, the display will
show the course changing towards the new
bearing. The SP-70 or SP-80 will bring your
boat onto the new course. It will steer
towards the Waypoint using the information
from the Nav device and the compass.
If the vessel seems to steer away from the
course line, or back to it’s starting point,
push and hold the Flush Key and press the
Green Key once. Please read the section
called “Navigation Interface.”
P/N 29010049 V1.2

The Navigation Interface
Because of this, the SI-TEX Autopilot lets you
change the way it interprets the direction of
cross track error. In NAV MODE, press the
Flush Key. The display will show either [---‘n]
(normal) or [---r] (reversed). Use the Green
Key to change the setting.
Your cross track error direction is correct if
the Autopilot is following the course line.
Your SI-TEX Autopilot will receive information
sent to it from a navigation device (such as a
LORAN, plotter or GPS) in NMEA 0183
format.
See page 41 for navigation input connection
instructions.
If the Autopilot is steering
away from the course line
while
the
Navigation
Interface is on, then the cross
track error direction may be incorrect.
Change the cross track error sense. If the
Autopilot begins steering towards the course
line, you have solved the problem.
Using information from a compass and the
navigation device, the Autopilot will steer your
vessel along a course line to a waypoint. The
Autopilot will also steer your vessel through a
series of way points which the navigation
device has grouped together as a route.
The Autopilot cannot steer by the
information from the navigation device
alone.
NMEA 0183
Cross Track Error
The SP-70 AND SP-80 receives information
from LORAN, plotters, and GPS in the
National Marine Electronics Association 0183
language. A list of the usable data sentences
is as follows:
Cross track error is a measure of the distance
your boat has fallen away from the course
line.
Cross track error is measured as the length
of a line drawn from the course line to your
position at right angles to the course line.

Cross track error also has a left or right hand
direction. For example: The boat can be one
half a mile to the left of the course line.
Manufacturers have defined the direction of
the cross track in different ways. There is no
agreement on whether a left hand cross track
error means that the boat is to the left of the
course line or the course line is to the left of
the boat.

The Processor is too hot. This is usually due to a very high demand for
electrical power from the reversing pump. It could also indicate a failure
inside the Processor.
CHECK: The Processor and the Processor space for heat sources.
Should the temperature rise still higher, the SP-70 or SP-80 will turn off
the steering outputs. When the temperature falls, the steering outputs will
turn back on. We recommend that you have the Autopilot serviced by a
SI-TEX dealer before it is used again.
The supply voltage is less than 9.5 Volts. The Autopilot cannot operate
reliably.
CHECK: Your batteries fluid level and the regulator in your generating
system.
This warning indicates that the SP-70 or SP-80 has been producing a
larger than normal output current for a period of time. This might be due
to increased mechanical resistance in your steering system.
If this warning appears after an extended period of use, try to think of
something that might have changed after the Autopilot was installed. Has
the rudder struck any submerged objects? Are there any bearings that
need grease? Is the rudder fouled?
If this warning appears when you first use your Autopilot, check that your
steering gear moves easily.
CHECK: Your wiring is correct. Look for any connections which allow a
short circuit. If you have an electric motor in your steering system, look
for burned or shorted windings.

Problems Without An Error Code
The Autopilot will not turn on.
You have one of the following problems:
1.
The battery is dead or the battery connections are
faulty.
2.
The computer is faulty.
3.
The program is faulty.
4.
The fuse is faulty and must be replaced. See page 40.
5. A short on the +5V line. Check RFU cable for short
between 1 & 3.
The Autopilot starts the Set-up
Routine. The display shows
[HO S].
The Autopilot detected an error in its memory and then
erased the defective memory. You must now do the Set-up
Routine. You will not have to bleed your hydraulic system
unless you have opened the hydraulic lines or run out of
hydraulic fluid.
The random occurrence of this problem is possible but
unlikely. If this problem occurs twice, your Autopilot may
need servicing. Contact your SI-TEX dealer.
The Control Head display
goes blank, the Autopilot
ceases steering and you have
manual control.
The SP-70 or SP-80 Control Head may be disconnected.
For safety reasons, should the Control Head inadvertently be
disconnected, the Autopilot will automatically switch off.
+5V may be shorted due to short on the Rudder Feedback
Pot or cable.

Connecting a Second Location or Second Station Options
Your Autopilot system can support remote autopilot operation in one of two ways:
1) The first option is to install one or more Second Location Kits (part #10080034). This allows
the user to connect and use an SP-70 Control head at several locations. If you chose this method,
it is important to note that only one SP-70 Control Head can be connected at any given time. You
are in fact only moving your Control Head from one location to another.
2) The second option is to install a Second Station Kit (part #10080035). This allows the user to
connect two fully functional Control Heads at different locations. Only one of the two Control
Heads can be in command at any time, but transferring command from one to the other is as
simple as holding down the Red & Green Dodge Keys for 2 seconds.
Second Location Kit
Right-hand side showing optional second location connections
Part Number 10080034
The Second Location Kit contains all the items you will require to install a second location outlet for
your autopilot. The kit should contain the following items:
1.
2.
3.
4.
1 only Mounting Clip for the SP-70 Control Unit.
1 only Cable Gland and Nut.
1 only Receptacle and Cap with 30 foot cable.
1 only Stainless Steel mounting washer.
P/N 29010049 V1.2
81
To connect the cable, first loosen off the right-hand cap on the SI-TEX Processor Box and remove
the “knock-out” at the top of the cap by using a 9/32 inch (7mm) drill. Once the “knock-out” has
been removed, install the cable gland and the cable. Next connect the individual wires on the
second location cable to the middle terminal strip, paralleling the existing main receptacle wiring
(Cable 1). Test your connections by disconnecting the control unit from the main receptacle and
connecting it to the second station receptacle. For specific information on the installation of the
receptacle and the mounting clip, please refer to page 25 of this manual.

Operation
The Second Station is identical in operation to the Main Station as described in “Piloting with the
SP-70 or SP-80 Autopilot”. Only one of the controls can operate the autopilot at any given time.
The unit that is non-active will have a continuously flashing LCD display and the active control will
have a steady display. To activate the non-active control, press and hold both the Red and Green
pushbuttons for 2 seconds. This control will now become active and go into the same mode as the
previously active control was operating in.
Turning the Autopilot ON From The Main Station or the Second Station
To turn the autopilot on from either the Main Station or the Second Station, press the pilot key on
one of these units. The Autopilot will turn on and the same station will become active. The display
is solid.
Turning the Autopilot off from the Main or Second Station
The autopilot can only be turned off from the active station. From the station that is in command,
press and hold the Off key for 2 seconds. The autopilot system will now turn off.
NON ACTIVE Station: The display keeps blinking or flashing.

APPENDIX D
Connecting a Rudder Angle Indicator
Right-hand side showing optional RAI connection.
The cable gland for a rudder angle indicator is in your Accessory Bag. We do not supply a cable
for this installation but recommend a #22 gauge, two conductor cable that is round in order to
make a water-tight seal. The outer diameter of this cable must not exceed ¼ inch (6.5mm) or be
less than 5/32 inch (4mm). The gland for this input must be mounted on the end cap. To locate
the hole for the gland, look on the inside of the end cap. You will see several places where the
plastic has been formed so that a hole may be easily drilled. Drill the hole using a 9/32 inch (7mm)
drill. Place the gland from the accessory kit in the hole. Fasten it with the supplied plastic nut and
tighten securely.
P/N 29010049 V1.2
84
APPENDIX E
Connecting the NMEA 0183 Heading Output
Location of terminal strip J5
The SP-70 autopilot has a data bus that sends out NMEA 0183 heading information to other
external devices such as radars. Heading data is transmitted once per second and provides two
data sentences: HDM (magnetic heading) and HDG (magnetic heading, deviation & variation).
The signal is transmitted at 4800 baud and has enough output to drive one 0183 "listener". For
applications requiring more than one "listener" please contact the factory.
The NMEA 0183 data output format is a two wire signal. One wire (signal) connects to pin 1 of
terminal strip J5 and the other wire (return) connects to pin 2 of terminal strip J5. Terminal strip J5
is located in the lower right side of the SP-70 Processor circuit board (see above). The two pin
connector required for connecting the heading output is included in your accessory kit.
