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
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.
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), partially open the
choke. Prolonged choking will flood the engine
with fuel until the engine warms up. See Section
15: Troubleshooting Guide to correct the flooding
condition.
Idle the boat near shore and press the kill switch
located on the hull as shown.
Propeller Trim Angle
You may also adjust the propeller strut to add up
or down trim to the propeller by loosening the 2
propeller strut bolts and sliding the propeller strut
up to increase top-end speed (but steering response
will decrease and cavitation may occur if excessively
adjusted). Lowering the trim angle will increase
handling performance (but may cause the boat to
over-steer and decrease speed).
m 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.
m Periodically disassemble the clutch and
clean debris from the clutch shoes and the
inner clutch bell with DYN5505 Dynamite
®
Nitro Force.
