General Guidelines
It is important that you read and follow this instruction
manual, along with the Pro Boat radio system manual and
the Pro Boat .18 engine manual, before you run this exciting
boat. Failure to read and understand the manual could result
is personal injury, property damage or permanent damage to
your boat! It is also important to run your boat responsibly.
With proper care and maintenance, you will be able to
proudly enjoy your Miss Elam for many years to come.
This boat has been designed to race in an oval path, just like
its full scale counterpart. At high speeds do not attempt turns
to the left, as the boat may become unstable. If you have to
turn left, do so in a large diameter turn and at slow speeds.
Should your repair not be covered by warranty the repair
will be completed and payment will be required without
notification or estimate of the expense unless the expense
exceeds 50% of the retail purchase cost. By submitting the
item for repair you are agreeing to payment of the repair
without notification. Repair estimates are available upon
request. You must include this request with your repair.
Non-warranty repair estimates will be billed a minimum of
½ hour of labor. In addition you will be billed for return
freight. Please advise us of your preferred method of payment.
Horizon accepts money orders and cashiers checks, as well
as Visa, MasterCard, American Express, and Discover cards. If
you choose to pay by credit card, please include your credit
card number and expiration date. Any repair left unpaid or
unclaimed after 90 days will be considered abandoned and
will be disposed of accordingly. Please note: non-warranty
repair is only available on electronics and model engines.
When operating the boat, stay clear of people, full-scale
boats, stationary objects and wildlife. It is preferable to
operate the Miss Elam in low wake, low wind conditions
and in areas free of people, wildlife and objects.
Before you operate your model, make sure that
your frequency is clear. If someone is operating on
the same frequency, both models could go out of
control, possibly causing damage to the models or to
others. Check all of the hardware, manifold, pipe and
propeller for security before and after each run.
If at any time while operating your model you sense any
abnormal function, end your operation immediately. Do not
operate your boat again until you are certain the problem
has been corrected. Always stay clear of the propeller.

batteries have been installed correctly.
m 6. Turn the radio off.
m 3. Install the "AA" batteries into the
transmitter. Be aware of the proper
polarity when inserting the batteries.
Section 2: Turn Fin
The Miss Elam comes with the turn fin installed
on the right sponson. You will want to run the
Miss Elam in an oval and in an area that will
allow you to make right turns (clockwise).
Do not attempt to make tight left-hand turns
(counterclockwise), or you could easily flip
the boat. If you need to make a left turn, do
so in a large diameter turn at slow speeds.
8
Section 3: Filling the Fuel Tank
We recommend that you use Blue Thunder™
20% fuel. For maximum performance, we
recommend Blue Thunder Race Formula. Blue
Thunder fuels are specifically formulated for
excellent power and engine protection.
Section 4: Range Checking the Pro Boat Radio System
Locate the fuel tank inside the cockpit area and
unscrew the lid. Use either the DYN2009 Fast
Tap™ quart bottle spout that has been attached
to the quart of fuel or the DYN2003 Fuel Bottle
to fill the fuel tank with your selection of Blue
Thunder fuel. After you have filled the fuel tank
and re-installed the lid, wipe away any excess
fuel that may have been spilled inside the hull or
elsewhere on the boat. Immediately seal the fuel
container by putting the lid back on after refueling
in order to protect the fuel from moisture.
Before the first run of the Miss Elam, range
check the radio for proper operation and
to ensure proper control movement of the
rudder and throttle. Also ensure that the
antenna on the boat is extended properly and
that all batteries are in working condition.
m 1. With the radio system turned on
(transmitter and receiver) and the
transmitter antenna down (engine off), walk
off 40 to 50 paces from the Miss Elam.
m 2. Have an assistant remain with the boat
to check for proper control movement of
the rudder from your transmitter input.
m 3. If everything appears to be operating
correctly, raise the antenna and start the engine
(refer to Section 5 of this manual and to the
separate PRB .18 engine manual). Place the boat
in the water and run it (at about 1⁄3 throttle)
close to the shoreline. If the radio system is
operating properly, you can begin to run the
boat faster and further away from the shoreline.
Note: It is a good idea to range
check prior to operating your boat
after any repair, installation of new
batteries, or at the beginning of
each boating season.

Section 5: Starting the Pro Boat .18 Engine
Water-Cooled Engine
Because the Pro Boat .18 engine is water-cooled
and not air-cooled, make sure that you do not
run the engine for an extended amount of time
outside of the water. Continuously monitor
the water outlet when the boat is running to
make sure that the water is reaching the engine
head. If the water does not reach the head to
cool it, the engine will overheat and fail. This
could cause permanent damage to the engine.

Hand-Held Starter
m 1. Fully charge a 7.2V sub-C battery pack
and install it in the starter as shown.
Higher Idle
Leaner
The Pro Boat .18 engine comes equipped with
the Pro Boat Precision Rotary Carburetor. Each
Precision Rotary Carburetor is pre-adjusted at
the factory. This setting should be approximately
21⁄2 turns open for the high-speed and 21⁄2 turns
open for the low-speed needle. This should
give you a slightly “rich” mixture of fuel to the
engine. This setting is the safest way to break
in your engine. For further details regarding the
Precision Rotatry Carburetor, please consult
Section 2 of the Pro Boat .18 instruction manual.
m 2. Slide the starting wand (which is stored
inside the battery cover) into the end of the
starter, then replace the battery cover.
10
Section 5: Starting the Pro Boat .18 Engine
Operation
m 3. Turn on your radio system and attach a fully
charged glow igniter (DYN1925) to the glow
plug. Insert the starting wand into the Tiger
Drive and actuate the starting switch until
the engine begins to run. If the engine does
not start, place your index finger over the
carburetor and actuate the starter until you see
fuel enter the carburetor through the fuel line.
Note: Stop operation immediately
if the engine enters a hydro-locked
condition as serious engine damage
may occur if operation is continued.
Remove the glow plug, invert the
boat and operate starter to remove
raw fuel before resuming normal
operation.
During break-in, the low-speed needle should be
slightly rich and the high speed needle should be
very rich. After a few tanks of fuel, begin to lean
the engine out. Adjust the high-speed needle 1⁄16
of a turn at a time. It generally takes about five
to six tanks of fuel before you want to lean out
the engine until it supplies good power. Do not
skip this process of break-in. Failure to follow this
procedure could damage your new engine. For
further details on breaking in your engine, please
see the separate Pro Boat .18 instruction manual.
Note: It is common for an ABC
engine to go through a glow plug or
two during break in.
Needle Settings
When adjusting the settings, always adjust the
needles in small increments, about 1⁄16 of a full
turn at a time. Do not set the engine too lean,
as it shortens the reliability of the engine.
After you have attained the correct needle
settings, the engine will have a strong sounding,
high-pitched whine at full speed, and a thin trail of
blue/white smoke will come from the exhaust.
Idle Adjustment
The last setting to set is the idle screw. To obtain
a higher idle, turn the idle screw clockwise; for
lower idle, turn the idle screw counterclockwise.
You may have to “blip” the throttle on the
transmitter (applying throttle on/off) while
trying to start the engine. New engines are
harder to start because of the tight piston/
sleeve fit. Never start an engine at 1⁄2 to full
throttle, as this will cause over-revving which
may cause premature wear and breakage.
During the first tank of fuel, advance the idle
via the idle adjustment screw more than normal
to prevent stalling at idle due to the rich
fuel mixture for break in. Pinch the fuel line
nearest the carburetor to stop the engine.
Breaking In Your Engine
The first start-up of the engine is the most critical
moment of the engine’s life, dictating how the
engine will perform from that time forward.
Replacement Parts
In the event that you need to replace an engine part,
there is a complete parts listing in the Pro Boat .18
instruction manual. Exploded views will help you to
select the correct parts and make minor repairs.
Head Shims
Several head shims are added at the factory to
make the engine easier to start when new. After
break in, you may remove all but one of these
shims to increase compression and power.
Maintenance
Lube the gears inside the drive with waterproof
grease every 30 hours of use.
Check all screws for tightness after each run.
11
Section 6: Maintenance
Lubrication
It is important to lubricate the flex shaft of
the Miss Elam, Pro Boat recommends genuine
Pro Boat Marine Grease and Grease Gun
(PRB0100), with silicone cable grease after
every two hours of operation. Do not forget to
do this. You can purchase this silicone grease
at your local hobby store. To lubricate the
drive shaft, follow these simple instructions.

12
Section 6: Maintenance
m 4. Carefully pull the ferrule away from
the stuffing tube. You will need to pull at
an angle to clear the aluminum strut.
m 5. Liberally lubricate the entire length of the
flex shaft with silicone cable grease as shown.
m 6. Carefully re-install the flex shaft and nylon
bushing, making certain that you correctly
tighten the collet nut. Next, re-install
the drive shaft and propeller and tighten
setscrews on the flats of the drive shaft.
