Use only Evolution 2-cycle synthetic oil and gasoline
mixed 32:1 to power the Formula Hydro.
Keep the fuel in a moisture-free environment,
as stale fuel will cause the Zenoah G26M engine
to lose performance.

Parts Needed

Unleaded gasoline
Evolution 2-stroke oil (EVOX1001Q)

1. Mix gasoline and 2-stroke oil (EVOX1001Q) 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.

Important

Range check your radio system before the first
run of the Formula Hydro to make certain it is
functioning correctly. Make sure the receiver
antenna is extended properly.

1. With the boat in its stand, the radio

system turned on and the transmitter antenna
down, walk 30 paces (90 feet) from the
Pro Boat Formula Hydro.

2. Have an assistant remain with the boat

to check for proper control movement
from your transmitter input. When you are
satisfied the radio is functioning properly, you
can continue.

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.

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), open the choke.
Prolonged choking will flood the engine with fuel.
See Section 15: Troubleshooting Guide to correct
the flooding condition.

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.
