4. Replace the hatch and secure it by pushing straight
down on top of the rear hatch lock.
CHECK THE RADIO SYSTEM
• Standing behind the boat with both the receiver and
transmitter powered up, rotate the wheel to the left. The
back of the rudder should move towards the left. Move
the wheel to the right. The back of the rudder should
move towards the right. If this is not the case, simply
move the transmitter steering servo reverse switch to the
other position.
• Squeeze the trigger on the transmitter; this should open
the throat of the carburetor. Conversely, pushing the
trigger should close the throat completely.
RUNNING THE ENGINE
Before running the engine, read the manual completely.
There are Several Simple Steps to Starting the Engine:
IMPORTANT: The propeller will begin spinning as soon as the
engine starts! Be certain that the propeller is unobstructed;
failure to do so will damage the prop.
❏
1. Install a glow plug if one is not in your engine. The
glow plug threads into the top of the cylinder head.
❏
2. Fill the tank almost to the top. Leave a little air at the
top of the tank.
❏
3. Open the high-speed needle valve 2-1/2 turns out
(counterclockwise) from fully closed. The high-speed
needle is sticking up on the right side of the carburetor
(looking at it from behind the boat). If you have previously
run the boat, keep the same needle valve setting that you
used on your last run.
❏
4. Prime the engine by placing a fi nger over the carburetor
opening and pulling the starter handle 2-3 times or until
you see fuel entering the carburetor. The quantity of fuel
drawn into the engine by priming is an important factor in
starting the engine successfully.
❏
5. Secure the glow starter onto the engine’s glow plug.
❏
6. Check that the throttle is 1/8” open from the fully
closed position. To adjust the idle speed, turn the idle
stop screw in (clockwise) to increase the idle speed or out
(counterclockwise) to slow the idle speed. Adjust the idle
stop screw 1/8th of a turn at a time until the desired speed
is reached. Pull the handle of the recoil starter in quick,
short pulls. Repeat if necessary, until the engine fi res. DO
NOT PULL THE RECOIL HANDLE MORE THAN 381mm
[15"]; DOING SO MAY DAMAGE THE PULL-START.
❏
7. With the engine started, remove the glow starter after
10-15 seconds.
❏
8. Put the hatch back in place and rotate the hatch lock
at the rear of the boat to secure it in place. BE CAREFUL
NOT TO TOUCH THE SPINNING PROP!
If the engine fails to start, refer to the ENGINE
TROUBLESHOOTING FLOWCHART on page 11.
BREAKING IN THE ENGINE
To insure long life and good performance from your
AquaCraft .18 engine, you MUST break-in the engine. The
break-in period is critical for long life of the internal parts
of the engine. This should be done over the fi rst 5 tanks
of fuel.
SOME THINGS TO REMEMBER DURING BREAK-IN
❏
1. Before running your SuperVee 27 Nitro it is a good
idea to check the water cooling system to be sure all the
lines are properly connected and in working condition.
❏
2. Use the same fuel that you will use for normal running.
Use nitro fuels that are specially formulated for model
boat engines. Typically this would be 30-65% nitromethane
boat fuel.
❏
3. Resist the urge to accelerate and decelerate the
boat quickly.
❏
4. Break-in puts stress on the glow plug and you can burn
it out. Make sure you have an extra plug or two on hand.
