• Never operate your model with low transmitter batteries.
Water-Resistant Boat with Waterproof Electronics
Your new Horizon Hobby boat has been designed and built with a
combination of waterproof and water-resistant components to allow you to
operate the product in calm, fresh water conditions.
While the entire boat is highly water-resistant, it is not completely
waterproof and your boat should NOT be treated like a submarine. The
various electronic components used in the boat, such as the ESC, servo(s)
and receiver are waterproof, however, most of the mechanical components
are water-resistant and require additional maintenance after use.
Metal parts, including the bearings, pins, screws and nuts, propeller, rudder,
rudder mounts, prop struts, as well as the contacts in the electrical cables,
will be susceptible to corrosion if additional maintenance is not performed
after running in wet conditions. To maximize the long-term performance of
your boat and to keep the warranty intact, the procedures described in the
"Wet Conditions Maintenance" section must be performed regularly.
CAUTION: Failure to exercise caution while using this product
and complying with the following precautions could result in
product malfunction and/or void the warranty.
General Precautions
• Read the WET CONDITIONS MAINTENANCE procedures and make
sure that you have all the tools you will need to properly maintain your
boat.
• Not all batteries can be used in wet conditions. Consult the battery
manufacturer before use. Caution should be taken when using Li-Po
batteries in wet conditions.
• Most transmitters are not water-resistant. Consult your transmitter's
manual or the manufacturer before operation.
• Never operate your transmitter or boat when lightning is present.
• Salt water is very conductive and highly corrosive. If you choose to run
your boat in salt water, immediately rinse the boat in fresh water after
each use. Operating your boat in salt water is at the sole discretion of
the modeler.
Wet Conditions Maintenance
• Drain any water that has collected in the hull by removing the drain plug
or canopy and tilting the boat in the appropriate direction to drain the
water.
CAUTION: Always keep hands, fingers, tools and any loose or
hanging objects away from rotating parts.
• Remove the battery pack(s) and dry the contacts. If you have an air
compressor or a can of compressed air, blow out any water that may
be inside the recessed connector housings.
• Remove all moving parts. Dry and lubricate parts after every 30 minutes
of operation or if the boat becomes submerged.
NOTICE: Never use a pressure washer to clean your boat.
• Use an air compressor or a can of compressed air to dry the boat and help
remove any water that may have gotten into small crevices or corners.
• Spray the bearings, fasteners and other metal parts with a water-
displacing light oil or lubricant.
• Let the boat air dry before you store it. Water (and oil) may continue to
drip for a few hours.

Battery Charger
Choose a charger designed to charge the recomended Dynamite
11.1V 5700mAh 3S 80C Li-Po battery. We recommend either the Dynamite
Prophet ™ Sport Plus 50W AC/DC Charger or the Dynamite Prophet Sport
Duo 2 X 50W charger. Refer to your charger manual for charging instructions
and safety information.
NOTICE: Never charge a battery in the boat or damage may result.
Low Voltage Cutoff (LVC)
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, and the boat slows noticeably.
Disconnect and remove the Li-Po battery from the boat after use to prevent
trickle discharge. Charge your Li-Po battery to about half capacity before
storage. LVC does not prevent the battery from over-discharge during storage.
NOTICE: Applying the throttle after the LVC will over discharge the
battery and cause battery damage.
Tip: Monitor your boat battery's voltage before and after boating by using
a Li-Po Cell Voltage Checker (DYN4071, sold separately).
NOTICE: Your boat is set up for 50+ MPH using 2 DYNB3811EC batteries
in calm water conditions ONLY.
NOTICE: Using a larger propeller or a propeller with more pitch than the
one included will damage the electronics and battery packs of your boat.

1. In the hull, use 2 10mm open-end wrenches to loosen the collet nut from the flex shaft.
2. Slide the flex shaft out from the stuffing tube and drive strut at the rear of the boat.
Tip: Use paper or cloth to touch the flex shaft and other lubricated parts.
3. Wipe the old lubricant and material from the flex shaft.
4. Lubricate the full length of the flex shaft assembly up to the drive dog using marine grease (DYNE4200
or DYNE4201). Also apply grease to the collet threads.
5. Carefully reinstall the flex shaft in the drive strut, stuffing tube and collet. If the flex shaft is difficult to
remove or install in the collet, use a flat screwdriver to spread the grips of the collet.
6. Ensure there is a 3–4mm gap between the drive strut and drive dog to allow for flex shaft shrinkage
under load.
MOTOR
NOTICE: Running the boat in saltwater could cause some parts to corrode and possibly damage

4. Connect the battery pack to the ESC power
connector.
Tip: Before placing your boat in the water,
secure the canopy on the hull. Apply clear tape
(DYNM0102), if desired.
Tip: Move the packs forward or back to adjust the
center of gravity for your boat. Move the packs
toward the bow so the bow rides lower in the water.
Move the packs away from the bow so that the bow
rides higher in the water. Too much of the bow in
the water will cause excessive friction, causing the
electronics to overheat.
