General Guidelines
It is important that you read and follow this
®
instruction manual, along with the JR
system manual and the Zenoah
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 LLumar 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.
When operating the boat, stay clear of people,
full-scale boats, stationary objects and wildlife. It is
preferable to operate the Miss LLumar 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

Section 7: Fueling the Tank
Use only Zenoah® 2-Cycle Synthetic Oil and
gasoline mixed 32:1 to power the Miss LLumar.
Keep the fuel in a moisture-free environment,
as stale fuel will cause the Zenoah G26M engine to
lose performance.
Section 8: Fuel/Oil Mixture
Parts Needed
Unleaded gasoline
Zenoah® 2-stroke oil
Section 9: Range Check the XR3i Radio System
Important
Range check your radio system before the first run
of the Miss LLumar to make certain it is functioning
correctly. Make sure that the receiver antenna is
extended properly.
1. With the boat in its stand, the radio system
turned on and the transmitter antenna down,
walk off 30 paces (90 feet) from the Pro Boat
Miss LLumar.
2. Have an assistant remain with the boat
to check for proper control movement
from your transmitter input. When you are
satisfied that the radio is functioning properly,
you can continue.
™
1. Mix gasoline and 2-stroke oil (ZEN20001) at a
mixing ratio of 32:1 (gas to oil).
2. Remove the fuel tank cap and fill the fuel tank
with the gasoline and oil mixture. Use a funnel
to prevent spills. If you do spill, be certain to
immediately wipe it up with a clean towel.
Note: Always perform a range
check prior to operating your boat
after any major repair, installation of
new batteries or at the beginning of
each boating session.
3. With your assistant again 90 feet away, re-
start the engine. Quickly repeat the same range
check as above, carefully making sure you
observe proper control movement from your
transmitter input. Make certain you complete
this within 60 seconds to prevent the engine
from overheating. Push the kill switch to stop
the engine. Once you are satisfied your radio
system has passed the range check, you are
ready to start the engine and launch your boat.
10
Section 10: Starting the Engine
Note: The Zenoah® G26M
carburetor is factory adjusted to
deliver optimum performance. See
the Zenoah Engine manual for
fine-tuning adjustments and other
helpful information to make your
RC boating experience trouble-free.
Priming the Engine
Pull-starting the Engine
With an assistant holding the boat to the boat
stand and bracing the engine with one hand, pull
the starting cord briskly several times. Once the
engine fires (begins to start), open the choke.
Prolonged choking will flood the engine with fuel.
See Section 15: Troubleshooting Guide to correct
the flooding condition.
Press the priming bulb several times until it becomes
filled with fuel. This is not necessary if the engine
has recently been run.
Choking the Engine
Close the choke by rotating the small yellow
tubing extension. This is not necessary if the
engine is warm.
Note: The engine is water-cooled.
Refrain from running the engine
without proper cooling water or
engine damage will result. Carefully
place the boat in the water as soon
as possible after the engine has
been started.
11
Section 11: Stopping the Engine
Idle the boat near shore and press the kill switch
located on top of the cockpit as shown.
Section 12: Initial Launch of the Miss LLumar
With the transmitter antenna up, maneuver the Miss
LLumar in an oval, turning only to the right at slow
to medium speeds. Make certain that the boat and
radio system are functioning correctly.
As you are running the Miss LLumar in an oval,
watch for water being discharged from the water
outlet on the left side of the hull. Water flowing
from the water outlet indicates the engine is
being properly cooled. If you do not notice any
water coming from the water outlet, bring the
boat in and make sure that the water cooling line
or the brass water pickup located near the rudder
are not clogged.
If at anytime you notice the boat and/or radio
system are not functioning correctly, end the
operation of the boat immediately and do not run
the boat again until you are confident the problems
have been corrected.

jackets mounted on the left side of the boat when
the engine is running and the boat is in the water. If
water does not stream out of either the exhaust or
cylinder head cooling ports, immediately stop engine
operation and remove obstructions in the lines or
replace broken cooling lines.
Hint: To test each cooling line
for obstructions or a leak in the
cooling system, place a piece of
tubing over the water inlet tubes
in front of the rudder and blow
into the tube. When testing for
obstructions in the cooling system,
be sure to isolate each system by
pinching the appropriate water lines.
Water-Cooled Cylinder Head and Exhaust
Manifold Cooling Jacket
The exhaust system is cooled independently from
the cylinder head. See line drawings for proper
cooling line routing. Do not alter the cooling line
routing method.
13
Section 14: Clutch
The centrifugal clutch automatically engages when
the engine rpm is increased. Be sure that the idle
speed adjustment is set low enough so that the
propeller does not rotate at idle.
Periodically disassemble the clutch and clean debris
from the clutch shoes and the inner clutch bell with
DYN5505 Dynamite® Nitro Force.

Section 16: Hull Care
The hull of the Miss LLumar is finished using the highest quality paints and the most advanced painting
methods available. The base coat/clear cote technique delivers an amazing shine that is as durable as
it is beautiful. To keep your Miss LLumar looking new, you should apply a wax coating as used on
automotive finishes to prevent oxidation and to further protect against damage caused by fuel and other
harmful chemicals.
Section 17: Maintenance
The Pro Boat™ Miss LLumar should provide many
hours of exciting high-speed racing fun with just
minor maintenance. Preventative maintenance is
very important. Taking the time to make sure all
of the screws and bolts are properly secured before
each run and after each operation and regularly
lubricating the flex cable will prevent
many problems.
Replacement parts are available from Pro Boat. See
the back of this manual for specific descriptions and
item numbers.
Items Required
2mm hex wrench
Waterproof grease
Threadlocking compound
It is vitally important to properly lubricate the flex
drive shaft and the propeller shaft with heavy cable
grease every 5–10 hours of operation. You will
also find that it will eventually become necessary
to replace the Teflon liner sleeve of the drive shaft.
At some point, it may also become necessary to
replace the drive shaft (flex cable) as well.
15
Section 17: Maintenance (cont)
Simply follow the instructions below to properly
lubricate your drive shaft.
1. Carefully note how the entire drive shaft is
installed. This is pivotal in order to properly
re-assemble the drive shaft after you have
finished lubricating it.
4. Lubricate the entire flex cable with
waterproof grease as shown and then re-install
the flex cable back through the liner and stuffing
box and into the clutch.
2. Loosen and remove the two 2.0mm set
screws that secure the propeller shaft to the
brass ferrule. Remove the prop drive dog and
nylon washer.
3. Remove the drive shaft flex cable. Replace the
Teflon liner as needed.
