For optimum performance, propeller balancing can
add several mph to top speed and reduce vibration.
There are several different propeller balancing tools
available. Read the instructions that accompany
the propeller balancing tool regarding removing
material from the propeller. Removing material from
the correct part of the propeller is crucial to the
performance of the propeller. Contact a local hobby
retail store for assistance.

Use only Zenoah
®
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
Zenoah
® 2-stroke oil
q 1. Mix gasoline and 2-stroke oil (ZEN20001) at a
mixing ratio of 32:1 (gas to oil).
q 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 that the receiver
antenna is extended properly.
q 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
™ Formula Hydro.
q 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.
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.
q 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.
