Getting Started
1. Power ON the transmitter.
2. Connect the battery to the IC3 connectors on the receiver/ESC.
3. Power on the receiver/ESC.
4. Test the transmitter's control of the boat with the boat on the
display stand.
Low Voltage Cutoff (LVC)
The factory default setting for the LVC in the ESC included with your
boat is set at 3.2V per cell. Discharging a Li-Po battery below 3V per
cell may damage your battery. The included ESC protects the boat
battery from over-discharge using Low Voltage Cutoff (LVC). Before
the battery charge decreases too much, LVC removes power supplied
to the motor.
The boat drastically slows or stops completely once LVC is activated.
Releasing the throttle and reapplying it will provide a limited amount
of power to safely return the boat to shore. Repeated use after LVC is
activated will damage the batteries.
Once LVC has been activated, the ESC status light will flash red
continuously indicating that the ESC is in LVC mode.
NOTICE: Repeated operation to LVC will damage the battery.
LVC can activate prematurely if you use (1) a low C-rated battery or
(2) an old, worn, and/or weak battery.
Boating Tips
During the first run, we recommend calm wind and water conditions to
ensure that the boat is properly set up. Maximum speeds of 35 MPH/+
can be achieved once you have set up the boat for your specific
conditions. Top speed will also be determined by the battery's ability to
efficiently deliver power to the motor via the ESC.
1. Consult local laws and ordinances before choosing a location to
pilot your boat.
2. Carefully place the boat in the water.
3. Operate the boat at slow speeds near the shoreline. Avoid objects
in the water at all times. When the boat is moving forward, ensure
water flows out of the coolant outlet.
4. Once you are comfortable operating the boat at slow speeds, it is
safe to operate the boat farther from the shore at higher speeds.
5. Bring the boat back to shore when the motor starts to pulse.
NOTICE: Never operate your boat in less than 12 inches (30.5 cm)
of water.
CAUTION: Never attempt to retrieve a downed boat by
swimming. If you need to retrieve your boat from the water, use
fishing equipment or another boat.

The average run time using the recommended battery (SPMX32003S30)
is approximately 5–7 minutes, depending on throttle usage. Limited run
time may indicate worn or weak batteries.
TIP: If you've installed a freshly charged battery and LVC activates
within the first minute of operation, replace your worn or weak
batteries with the recommended batteries.
TIP: Monitor your boat battery's voltage before and after boating by
using a Li-Po Cell Voltage Checker (SPMXBC100, sold separately).
Disconnect and remove the Li-Po battery from the boat after use to
prevent trickle discharge. Charge your Li-Po battery to half capacity
before storage. During storage, make sure the battery charge does
not fall below 3V per cell. LVC does not prevent the battery from over-
discharge during storage.
NOTICE: When running at full speed in choppy water, the propeller
may exit and re-enter the water repeatedly and very quickly,
subjecting the propeller and drive shaft to some stress. Frequent
stress may damage the propeller and drive shaft.
In rough water and windy conditions, consider:
• mounting the batteries further forward for added stability
• adjusting the struts downward to prevent the boat from overturning
Avoid boating near:
• watercraft
• people (swimming areas, fishing areas)
• stationary objects
• waves and wakes
• rapidly moving water
• wildlife
• floating debris
• overhanging trees
• vegetation
