TR-1 Gold

Due to the restricted space around the
carburetor and intake manifold the
Honda 8/9.9 throttle actuator runs the
throttle only from idle to two thirds full.
Though you do not get auto control to
full throttle, you do get very ne control
in the normal trolling range. You will
need to keep the manual throttle lock
loose. The manual throttle will still
operate to full throttle, and if you use
the manual throttle lock the autopilot
will function fully at speeds above two
thirds, as well as below.
Remove the cover (top cowling). Find
the carburetor on the starboard side
of the engine. Remove the upper air
intake horn bolt.

Tools Required:
One; #1 (small) Phillips Screw Driver
One; #2 (regular) Phillips Screw Driver
One; Wrench 8 MM
One; Wrench 10 MM
Thread lock (Loctite or similar (not shown)

Use the #10 screw provided with the
actuator to replace the screw you just
removed and attach the throttle actuator
assembly (item 1) as shown. Keep both
washers on the screw head side of the
air horn. Apply a little thread lock to the
screw and tighten it.
Near the left end of the carburetor
there is a shaft with a nut on
it. This is the buttery shaft.
Remove the nut and lock nut. Be
careful not to drop them in side
the cowl.
Installthecarburetorbellcrank
lever on the shaft as shown.
The little screw head will be
on the near side. The string
connecting it to the actuator
motor should enter from the
back. Tighten the nut.

Loosen the little screw on the
carburetor bell crank lever a
few turns. With the carburetor
at idle position and the shaft of
the throttle actuator motor fully
extended toward the carburetor,
pull the string (120 Lb. Test Spetra
shing line) through the hole in
carburetor bell crank lever till it
is just tight. Then pull just a little
slack in it as shown in the picture
to the right. Wrap the string over
the top of the screw and tighten
the screw. That will lock the
string in position. Be sure that the
carburetor bell crank lever rotates
and freely returns reliably.
Run the wire that is attached to the actuator out of the motor housing, to the TR-1 Gold E-H unit and plug
it in to connector 2. Be sure to route the wire away from moving things around the motor. The best place
for the wire exits the motor cowling will depend on many things. Some of these things are; where the motor
is mounted, where the E-H is mounted, and weather the motor is a tiller or remote model. Where ever you
decide to bring the wire out, be sure it is not going to get cut or kinked. You may run the wire over or through
the transom. Be sure to have enough slack to accommodate the full range of motor travel as well as kicker
bracket or jack travel. Arrange or tie the wire to prevent it from being snagged by other ttings or equipment
when your kicker or other equipment move

Testing the Actuator Functions:
Please refer to the startup section of your owner’s manual before operating your handheld and run-
ning the throttle actuator.
1. With the outboard in the water, or with a proper coolant ush device connected, start the out-
board and let it warm up to operating conditions. Be prepared to kill the outboard ignition if the
idle speed is too high when the engine starts.
2. With the outboard in idle position make sure there is proper slack in the pull string on the throt-
tle actuator. If the motor does not go to idle, reposition the string by loosening the pinch screw on
the brass pivot.
3. Using the UP ARROW button on the Handheld verify that the engine rpm’s go up. Using the
IDLE/RESUME button on the handheld verify that the engine returns to idle. Check the throttle up
and down several times along with the idle/res and verify that you don’t have any problems.
