Safety
     You are responsible for the safeandprudentoperationofyourvessel.
Your TR-1 Gold Autopilot is a tool that will enhance your capability to 
operate your boat and catch fish.  It does not relieve you from the 
responsibility for safe operation of your vessel.  You must avoid hazards 
to navigation and never leave the helm unattended. 
You must always be prepared to promptly regain manual control of your kicker.  The 
autopilot and the throttle actuators can fail hard over.  Learn to operate your autopilot on 
calm and hazard free open water.
In case the autopilot becomes inoperable, remove the in line fuse from the battery power 
cable.
The steering cylinder can be removed from its mounting bracket on the outboard in case 
of hydraulic jamming.
Removing the actuating link between the stepper motor and the carburetor butterfly 
crank can disable the electric throttle. 
Caution:
 Before drilling holes in your boat, be sure you know what you are drilling into.
Watch out for fuel tanks, electrical cables, and hydraulic hoses. 
Do not run your pilot with the outboard hard on the steering stops for any 
extended time or you will burn out the pump motor. 
Be sure to leave the system in Standby mode whenAutopilotisnotin use, or if 
the kicker motor is not running.
We recommendyouuseonlyBioSOY hydraulic fluid in your autopilot hydraulics. 
Keep your hands out of the outboard steering hinge area, the autopilot may steer the 
motor and smash (or worse) your fingers.

TR-1 Gold Specifications 
Introduction
This manual comprises two major sections.  The first section is a guide to installation of 
the “onboard” components of the autopilot system on your boat.  The second section is a 
guide to adjusting and operating your system.  Installation instructions for the throttle 
actuator and steering cylinder are motor specific and are provided in separate manuals. 
Preparation 
You will be hard mounting three autopilot components in your boat:  1) The Electrohydraulic 
Unit.  2) The Deckmount switch.  3) The Sensor ball.  These components are shown in relation 
to each other and to the engine mounted components in the System Layout diagram on page 8.   
As indicated by this diagram, the Electrohydraulic unit and the Deckmount switch are to be 
located near the kicker and the Sensor ball is to be located FORWARD OF THE CENTER 
OF YOUR BOAT 
Spend some time to figure out where you are going to mount all of the components before you 
mount any of them.  Place the components where you expect to mount them and verify you 
have access to and routes for the cables and hoses that connect the components. 
x  Mounting Screws 
  Mounting screws are provided for through and blind hole applications.  You may choose 
to drill and tap the mounting surface.

x Access  
  The Electrohydraulic Unit is the place where all the components connect together and the place where 
fluid is added and fluid level is checked.   Leave room for service loops in the cables and hoses.
      The Deckmount switch should be easy to reach with your free hand when your other hand is on the 
kicker tiller. This can be done after  the initial turn on blinking setup is complete. In case of an 
emergency, quick access to the deckmount switch is a good idea, by pressing the button once it will 
take the autopilot to standby, allowing you to take control of the tiller handle.  Pressing the button 
again will return it to autopilot mode. 
  If you intend to hook up to GPS, the connection between the GPS and the autopilot is made at the 
Sensor ball and the  NMEA 0183 output on your GPS. 
x  Protection 
Locate the Electrohydraulic unit and Sensor ball in places where they will not get submerged or 
exposed to wash down. 
       Use a quality electrical insuating  grease compound on all electrical connections (Dow Corning 
#4)  except the orange connectors # 1,2,3, & 4. 
    
x  Moving Parts 
Hoses and cables that connect the Electrohydraulic unit to the engine mounted components 
need to be free from binding and kinking.  Be sure to remember your kicker moves up and down 
on the lift bracket, tilts up and down, and steers lock to lock.  
x  Hose Length 
  Try to keep the hose length between the steering cylinder and the Electrohydraulic unit short. But 
leave enough length for movement of Kicker (See note above on moving Parts). 
x  Magnetic Environment 
  The Sensor ball has a compass in it.  Do not mount the ball near magnetic materials, magnets 
(speakers and electric motors), or high current carrying wires.  Small, vehicle fixed, magnetic 
disturbances can be calibrated out, but moveable or changing magnetic disturbances such as anchors, 
anchor chain, and wiper motors should be kept at least 24” away.  A common problem is to have 
mounted the ball near a glove box, and then someone puts tools in the glove box.  Keep the Sensor 
ball away from Air Ride seats. 
x   Strain Relief and Cable Protection 
Do not let the connectors on the Electrohydraulic unit be the sole support for the cables connected to 
them.  Use the tie wraps to tie the cables down to the Electrohydraulic frame.  There are several holes 
in the sheet metal frame provided for this purpose. 
Don’t run cables and hoses over sharp edges.  Use grommets in through holes to protect the cables.

                  Locate the Electro-Hydraulic unit where it  
                                                          it will not be subjected to water submersion 
                                                          or spray from wash down. 
Tools 
You should gather the following tools before beginning installation.  See throttle and cylinder 
supplements for any additional tools that may be needed for your application. 
Tools
Power Drill 
#1 Phillips screw driver 
 .125 (1/8) or 3.17 mm dia. drill 
 .469 (15/32) or 11.90 mm dia. drill 
 Roll of masking tape 
 Rags 
 Knife 
 Pliers 
 Silicone RTV  
 Loctite or similar product 
 Electrical grease compound 
 (Dow Corning #4) 
Installation of The Electro-Hydraulic Unit 
    Step one (Template)
Find the mounting template in your autopilot 
documentation package.  Use the wall or floor 
section of the template as needed.   Decide which 
screw type you need.  Hold the template in the 
place with tape and drill right through it in the 
three indicated locations. See fig.5.  Remove 
template and install screws in the indicated 
locations on template.  Tighten these 2 screws 
down to 3/32” from the surface to allow enough 
space for the bracket on the pump to slide behind 
the screw.

Floor Mount:  Set the unit on the 
floor in front of screws.  Slide the left 
side back and engage the notch 
between the hose fittings around the 
left hand screw.  Pivot the unit on the 
left hand screw counter clockwise 
until the notch under the electronics 
box on the right hand side is engaged 
and the remaining hole you drilled 
lines up with the hole in the bottom 
tab of the right hand bracket.  When 
the holes line up, put the last screw in 
and the E-H unit is locked in place, as 
shown in fig.6.
Wall Mount:  Set in place by 
hanging the unit on the screws.
One is the keyhole shape on the 
upper left backside of E-H unit; the 
other is the notched area on the 
lower right side of E-H unit.  Lock 
E-H unit in place by lining up the 
last hole on upper right hand corner.
Please note:You will need to 
remove the black plastic 
thumbscrew to place the last screw, 
as shown in fig.7
You may run the red and black wires to the battery box now, but do not connect to 
the battery yet.
