HOW TO STOP YOUR ENGINE
Just as squeezing the throttle trigger on your transmitter
increases power, pushing the trigger the opposite way
decreases power. Pushing the throttle trigger should close
off the throat of the carburetor completely, cutting off air
intake and stopping the engine.
THE FIRST TANK
Your fi rst tanks of fuel should be used to run the boat at
a very rich high-speed needle valve setting. This allows
the fuel to carry as much oil as possible into the engine to
lubricate the internal parts during break-in.
TANKS 1 TO 3
❏
1. Open the needle valve 2-1/2 turns out from fully
closed (counterclockwise). This is factory set already, but
check it to make sure. When closing the high-speed
needle, close the needle until you feel some resistance.
DO NOT overtighten or you will damage the carburetor.
❏
2. Start the engine.
❏
3. Once the engine is started, adjust the high-speed
needle valve around 1/8th of a turn at a time, fi nding the
setting where the engine just barely runs. This may take a
few times. The engine will perform sluggishly and stall from
time to time – this is normal during the break-in process.
❏
4. Place the boat in water and run the engine at a medium
speed, periodically accelerating and decelerating.
❏
5. Continue running the engine until the tank is almost
out of fuel. Do not allow the engine to run out of fuel. This
leans out the engine and can cause overheating.
TANKS 4 & 5
Turn in the needle valve (clockwise) around 1/8th of a turn
from the previous setting. You should notice that the engine
performs better during each run. After the 5th tank, you
should be near to the peak performance of the engine.
RUNNING THE SUPERVEE 27 NITRO
Gently place the boat in water that is at least 8” deep and free
of obstacles (weeds, rocks, sticks, ducks, muskrats, etc.).
Throttle up to full speed. Note: Your SuperVee 27 Nitro may
cavitate for the fi rst 10 to 15 feet. This is normal! If the boat
has a tendency to turn right or left, adjust the steering trim
knob on your transmitter until the boat runs in a straight
line when the steering wheel is at neutral.
When you are ready to bring your boat back to shore,
drive it parallel to the shoreline. After you have stopped
the motor, turn the boat towards the shore.
DRIVING TIPS
The motor and propeller spin counterclockwise on your
SuperVee 27 Nitro. Torque from the engine and propeller
naturally cause the boat to turn better to the right than to
the left.
Your SuperVee 27 Nitro is very fast and very agile. It’s a
good idea to let off the throttle as you enter the corner.
Likewise if the boat starts to get out of shape you will want
to let off the throttle to get the boat settled back down. You
can make adjustments to the boat’s hardware for better
handling and even more performance, but just remember,
one small adjustment at a time. For more tuning info see

PROPELLER CHOICES
The propeller plays a huge part in how your SuperVee 27
Nitro performs. The FRP (Fiber-Reinforced Plastic) prop
that comes with the boat is a good all around prop but if
you want even more performance, try your hand at a metal
prop. To start with, here are a few good choices.
AquaCraft/GrimRacer 4053 (AQUA9715)
AquaCraft/GrimRacer 4052/3 (AQUA9716)
Octura X437/3, X438
You can make hardware adjustments to your SuperVee
27 Nitro to suit your driving style or achieve maximum
handling and speed for your water conditions.
Strut Settings: You can use the information below as a
guideline to help you understand what happens when you
adjust the angle of the strut. Remember that the prop and
water conditions play a huge part in the performance of
the boat.
