Center of Gravity

Moving the batteries to the front or back can significantly
affect the boat's performance.
1. Move the batteries toward the rear of the boat
to raise the front of the hull out of the water for
increased speed.

Drive Height

Lowering the drive will increase the propeller's ability to
bite at takeoff, but excessive lowering can cause the back
of the boat to feel loose and decrease top end stability.
Raising the drive helps eliminate oscillation or bouncing
and with top end stability, but excessively raising the
drive can reduce top speeds and cause cavitation.
If the conditions are questionable, adjust the prop strut
down a bit to reduce the likelihood of having the boat
overturn. The motor mount is slotted to allow you to
move the motor slightly when adjusting the propeller
strut. Loosen the motor mounting screws when
adjusting the propeller strut angle trim and retighten
after adjustment is complete. Use a 3mm hex wrench
and 7mm nut driver to loosen the bolt that attaches
the output to the bracket to adjust the height. Raise or
lower the prop strut. Tighten the bolt when adjustment is
complete.

Motor Care

• Prolong motor life by preventing overheating
conditions. Undue motor wear results from frequent
turns, stops and starts, pushing objects, boating in
rough water or vegetation and boating continuously at
high speed.

When You are Finished

1. Power off the ESC.
2. Disconnect the battery.
3. Power off the transmitter.
4. Remove the battery from
the boat.
Always store the boat open (without
the hatch and innner liner sealed) or
moisture may allow mold and mildew
to grow in the boat.

2. Move the batteries toward the front of the boat for
faster initial acceleration to eliminate oscillation or
bouncing and to increase stability.
You may also turn the dual rate dial down to reduce
rudder travel in rough water conditions.
• Over-temperature protection is installed on the ESC to
prevent circuit damage, but cannot protect the motor
from pushing against heavy resistance.
