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 Electronic Speed Control (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 below 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 through 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 where
lightning may be 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 every
use. Operating your boat in salt water is at the sole
discretion of the modeler.
• Even minimal water contact can reduce the life of
your motor if it has not been certified as water-
resistant or waterproof. If the motor becomes
excessively wet, apply very light throttle until the
water is mostly removed from the motor. Running a
wet motor at high speeds may rapidly damage the
motor.
• Driving in wet conditions can reduce the life of the
motor. The additional resistance of operating in water
causes excess strain.
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 disconnect the
ESC and motor. 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 the flex shaft and 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. Do not
spray the motor.
• Let the boat air dry before you store it. Water (and oil)
may continue to drip for a few hours.
