JetSurf™ motorized power boards were designed and manufactured by MotosurfWC and Formula 1 engi-
neers to push the limits of motor sports. The power boards created by JetSurf™ are the only motorized water
vehicles with the ability to be transported by hand, car, boat or plane (as hand luggage on international/
domestic carrier ights). This allows the users of JetSurf™ power boards to travel easily around the word –
aunique attribute in comparison to other motorized watercraft.
JetSurf™ parts and components are manufactured by MSR Engines, based in the Czech Republic. Thecom-
pany specializes in the development of combustion engines and specialized electronics.
JetSurf™ power boards are produced in a single factory that uses the highest standards of production technology.
Only the nest materials and components currently produced in the European Union are utilized. This compre-
hensive in-house production allows JetSurf™ to ensure themaximum precision and ecient production. Since
2017 the manufacturer has been an ISO 9001 certicate holder.
JetSurf™ power boards were developed with exceptional eort to minimize environmental impact. JetSurf™
power boards meet homologation (registration for racing) standards for noise emissions, as well as using an
internal combustion engine that enforces the Greentech technology and complies with the emission limits set
for motor vessels. The complete drive unit is certied and approved by the European Commission and received
the European Union label, CE. All this eort toward compliance with international standards has ensured that
the power boards are also compliant with North American requirements for personal watercraft.
EPA Emissions Regulations:*
JetSurf motorized surfboards are certied to the United States Environmental Protection Agency (EPA) as con-
forming to the requirements of the regulations for the control of air pollution from new watercraft engines. This
certication is contingent on certain adjustments being set to factory standards. §1068.101(b)(1) prohibits tam-
pering, removal or rendering inoperative any device installed onto the engine in compliance with EPA regulations
prior to sale and delivery to, as well as after the sale to, the ultimate purchaser of the product.
Maintenance, replacement, or repair of the emission control devices and systems may be performed by any
marine engine repair establishment or individual.
Emission Control Information is printed onto the Engines as permanent evidence of EPA certication.
The information contained in this User Manual represents the most up-to-date product data available at the

INTRODUCTION
This manual will help you to operate your vessel safely and easily. It contains a detailed description of the vessel,
its supplied or built-in accessories, systems and information about their operation and maintenance. Please
read it carefully and learn about the vessel before you start using it.
Do not set out on a ride until the conditions (wind force and wave height) correspond to the construction cate-
gory of your vessel and make sure you are able to safely control the vessel in these conditions.
This user manual does not include detailed maintenance or repair instructions. If you experience any problems,
contact the Authorized Dealer or manufacturer of the vessel. If you have the maintenance manual, please follow
it during the vessel maintenance.
Maintenance, xing and adjustments of the vessel can only be made by trained and qualied persons. Any
adjustments which might aect the safety characteristics of the vessel have to be checked, implemented and
documented by a competent person. The manufacturer of the vessel cannot be held responsible for any ad-
justments not approved by it.
In some countries it is required to have qualication or certicate to control a vessel or some other special
regulations might apply.
Always duly maintain your motorized power board and be aware it will wear with time and as a result of demand-
ing operation or bad handling.
Each vessel, regardless how hard-wearing it is, can suer severe damage if used incorrectly. This is incompatible
with its safe use. Always adapt the speed and course of the vessel to the conditions (wind force and wave height).
The person controlling the vessel must use suitable swimming aids described in the chapter PERSONAL SWIM-
MING AIDS in this manual. It is necessary to point out that in some countries the law requires wearing swimming
aids under all circumstances while using the JetSurf™ and is therefore necessary to comply with these national
legislations.
PLEASE KEEP THIS MANUAL AT A SAFE PLACE AND HAND IT OVER TO A NEW OWNER IF YOU
SELL THE VESSEL.
This user manual comprises of two parts. Any reference to the user manual always means both its
parts.

2A SAFETY MATTERS
BEFORE USING THE POWER BOARD THE FIRST TIME, READ THIS ENTIRE OWNER’S
MANUAL.
If any of the information is not clearly understood, contact the Authorized Dealers for clarication
and further understanding prior to operating the power board. Safety is the primary concern of Jet-
Surf™, and it needs to be for all owners and operators as well.
The Safety information provided in this Owner’s Manual cannot anticipate every circumstance that
may arise while maintaining and operating the power board. Basic safety information is provided
and it is not all-inclusive. JetSurf™ strongly encourages all owners and operators to regularly review
the U.S. Coast Guard safety information (www.uscg.mil and www.uscgboating.org)* and other safe-
ty-minded, watercraft websites and authorities which apply to the relevant area/region under which
the JetSurf™ power board is to be operated.
This is the safety alert symbol. It is used to alert you to potential personal injury hazards.
Obey all safety messages that follow the symbol to avoid possible injury or death.
DANGER indicates an imminently hazardous situation which, if not
avoided, will result in death or serious injury.

SAFETY MATTERS
DEFINITION
“Power board” or “motorized surfboard,” interchangeable terms in this Owner’s Manual, mean a ves-
sel that uses an inboard petrol-and-oil-powered engine, providing power to a water-jet pump as its
primary source of propulsion power. It is designed to be operated by a person (“rider” or “operator”)
sitting, standing or kneeling on the vessel. Direction of JetSurf™ is controlled by rider leaning to one
side or another, speed is controlled by throttle trigger located on the handle.
GENERAL COMMON SENSE
It is the responsibility of the owner and/or operator to comply with safe-
ty-related material provided in this Owner’s Manual and to regularly re-
view safety information provided by governmental agencies and local ju-
risdictions. Common sense should guide owners/operators at all times,
regardless of whether the engine is running or not. Failure to do so will
result in serious injury or death.
Riders are reminded that general common sense should be the rule for any and all outings. While
some objects appear above water and are easily avoidable, it may be necessary to pay special atten-
tion to underwater objects as well.
In using the power board, some common sense considerations are for safety of the rider and other
vessel riders, boaters and passengers, while common sense also is necessary to preserve the power
board in good shape.
JetSurf™ cannot anticipate every type of activity or negligent performance that could result in death/
injury or damage. The operator accepts responsibility for use of the power board in a safe and
sensible manner. Particular attention must be paid to surroundings at all times to avoid accidents.
Care must also be taken to avoid situations in which carbon monoxide fumes may become trapped
between objects or may be released out-of-the-water. Be certain to read the information regarding
carbon monoxide poisoning contained in this section of the Owner’s Manual.
With regard to damage to the power board, riders should avoid running it all the way to shore. Often,
beaches or shoreline are made up of rocks and/or sand that can scratch or dent the power board.
Such occurrences are not covered under the JetSurf™ Limited Warranty statement, which appears
later in this Owner’s Manual.
Familiarity with the nautical waters in which the power board will be operated is extremely important.
Currents, especially strong ones, can aect the performance of the power board and threaten the
safety of the operator. Pay attention to buoys and other markers also.
It is critical for all owners and operators to be prepared to maintain and operate the power board in
a responsible and common sense manner at all times.
All riders must use helmet, life vest and a safety leash at all times while operating JetSurf™ to prevent
any serious injury or death in the events of accident (you can nd more details in CLOTHING category).

DFI003/EN_part A
SAFETY MATTERS
CARBON MONOXIDE
Carbon monoxide (CO) is a gas and it can be extremely dicult to de-
tect, because it has no color, taste or odor and it can accumulate without
awareness. Exposure can be fatal in a matter of minutes. The eects of
CO are cumulative and repeated exposure to low amounts can have a
similar eect to a single high concentration exposure. Carbon monoxide
should be avoided, while any exposure should be treated immediately.
The exhaust on the power board is purposely located at the stern (rear) of the board. While emis-
sions from the engine are relatively low due to its purpose-built design which ventilates into the water
under normal operation, there are still some CO fumes as a natural by-product of a combustion
engine. Therefore, riders must operate the power board as designed. No one should ever be towed
behind the power board while it is in operation. The engine should not be operated when the power
board is out of the water (this can cause damage to the engine from over-heating also).
CO enters through the lungs and blocks oxygen. Milder symptoms of poisoning include headache,
nausea, itching or irritated eyes and dizziness. Victims often become increasingly weak and disorient-
ed. These symptoms should not be confused with alcohol intoxication.
Individuals who suer from lung- or heart-related issues may be aected more quickly. Alcohol and
tobacco use also accelerate symptoms. For all riders, regardless of health or ingestion, note that
physical activity will also hasten CO absorption.
In the even that someone shows evidence of CO poisoning, immediately shut o motorized surf-
board or any other combustion-engine in the area. Provide fresh air, if possible, and move the victim
to an area away from the CO concentration. Provide rst aid and seek professional medical assis-
tance immediately.

14
DFI003/EN_part A
ENGINE PREPARATION
Operation of the power board engine out of the water for more than
ten (10) seconds can result in permanent damage to the engine and ex-
haust system, (temperatures of cylinder shouldn’t be higher than 65 °C/
149°F). Such damage is not covered under the warranty.
Touching any part of a running engine, in particular any component that
is moving, can result in serious injury or death. If it is necessary to ac-
cess or touch an engine for any reason, the engine must be turned o.
EEngine also become increasingly hot with usage and can result in skin
burns if engine is not allowed to cool prior to touching it.
Never transport fuel except in D.O.T. (USA) or CE (Europe) -approved con-
tainers.
Transporting fuel in the engine or fuel tank can result in damage to Jet-
Surf™ or injury to people handling the board. Fumes from fuel are even
more volatile, explosive and generally dangerous than liquid fuel. Never
transport JetSurf™ power board with the tank inside. JetSurf™ transport
is described in detail in the chapter “TRANSPORT”, part A.
Later in this Owner’s Manual are instructions for the proper preparation and maintenance of the
power board’s engine. Be sure to read and follow these instructions.
Note also that operators should regularly verify that the engine is probably installed and rmly axed
to the engine housing. DO NOT attempt to start an engine that is not secure!
Operators and bystanders should NEVER touch any part of a running engine.
Avoid allowing any object, even small bio-degradable items (seaweed, sand, small animals...) to come
into contact with the engine. This could result in damage to the engine that would not be covered
under warranty.
Use only JetSurf™-approved (manufacturer) replacement parts. Using any other parts will void the
warranty and may adversely aect the operation and safety of the power board.
When starting the engine, ensure that individuals (especially children) are at least 33 feet/10 meters away.
The engine was designed and crafted for the JetSurf™ retail power board only. Never use
the engine for any other craft, object, projectile, or item. Such usage is expressly prohibited.

SAFETY MATTERS
CLOTHING
Persons in range of the power board’s engine moving parts should exercise caution to
avoid having clothing or hair come in contact. If clothing or hair become entangled in mov-
ing parts, injury may result.
Because the engine has moving parts, owners/operators should never wear loose clothing when the
engine is in operation. Straps, buckles, as well as the edges of cloth can become entangled in JetSurf™
moving parts.
If the owner/operator has long hair, it should be tied up or secured in some fashion so that the hair
cannot become entangled in the engine’s moving JetSurf™.
An injury can occur nearby the jets as a result of water inux into the body cavities. Conventional
swimwear does not protect suciently against water being forced into rectum or vagina. All the riders
must wear at least the bottom part of the neoprene suit or any other garment providing the same
protection. We recommend wearing footwear, gloves and glasses.
Helmets are a compulsory item of safety gear and must be worn at all times while riding. It is expected
that operators will, from time to time, fall o the power board, even in normal operation. Helmets
provide protection in the event the operator’s head would strike the board. Helmets are therefore a
mandatory accessory and should be manufactured to wear on the water, t properly and be relatively
lightweight. Manufacturer JetSurf™ makes no claims nor promises regarding protection, including that
aorded by helmets.
The use of an arm or leg leash is compulsory and must be used at all times while using JetSurf™.
PERSONAL FLOTATION DEVICES (PFDs)
It is the responsibility of the owner/operator to comply with any and all laws, statutes and requirements
for personal safety. American federal law requires the wearing of a U.S. Coast Guard-approved* person-
al otation device (PFD) under most circumstances. State and local laws and statutes may also vary
from federal requirements.
As JetSurf™ power boards are commonly dened as personal water craft it is essential for all users to
check with their relevant local Authorities for all information relating to the use of safety accessories.
JetSurf™ takes no responsibility for failure of users to comply with the relevant laws which apply to
the use of personal water craft in any specic location.
Authorized dealers are able to assist owners and operators in ensuring that they are properly outt-
ted for conditions and to comply with the law of the countries where JetSurf™ is used.
WARNING
* Valid for the USA

16
DFI003/EN_part A
LAW ENFORCEMENT
When underway, operators may be required to cease manoeuvres and allow U.S. Coast Guard* or
state law enforcement personnel to come alongside. Some Countries, States and jurisdictions may
require a minimum age to operate the power board, pass a training course, and/or possess an op-
erator’s license. Requirements vary widely. If operating in a location that allows minors, such activity
should be done only under adult supervision.
Be sure to check annually regarding requirements for legal and safe operation of the power board.
UNDER THE INFLUENCE
Under no circumstances should a power board rider ever operate under the inuence of alcohol
or drugs, including prescription drugs that have potentially disorienting side eects. This can be as
dangerous as driving a car while under the inuence!
REGISTRATION
In many jurisdictions, it will not be necessary to register the power board with the state of principal
use. However, because the power board is motorized, registration may be necessary. Verify with the
state and local law enforcement entities in the area in which the power board will be used most prior
to using for the rst time.
SPEEDING/NOISE
Some areas have restrictions regarding speed related to creating waves and maximal noise restric-
tions. Operators of power boards are required to adhere to these requirements.
ELECTRONIC DEVICES
Operating the power board requires full attention. JetSurf™ strongly recommends leaving cell phones
(including waterproof models), radios, iPods, and other devices ashore during outings. The distrac-
tions can potentially lead to accidents.
JUMPS ON JETSURFTM
NEVER JUMP with the motorized power board! Damage caused due to incorrect use of your JetSurf™
(for example jumps) is not covered by the guarantee.

DFI003/EN_part A
SAFETY MATTERS
REPORTING ACCIDENTS AND INSURANCE
Federal law requires reporting of accidents in which:
- A person dies;
- A person disappears from the vessel in what appears to be a situation that could have resulted in
death or serious injury;
-A person is injured and requires medical assistance beyond minor rst aid;
- Damage to vessel and/or property that exceeds the amount stipulated by law. The total may be
lower in some jurisdictions and it is the responsibility of the owner/operator to verify;
- The power board is destroyed.
Any instance in which other vessels or persons appear in distress, power board operators are re-
quired by law to oer assistance unless doing so would result in potential danger to the power board
operator. Good Samaritan protection is provided to anyone who oers good faith assistance.
Even when others operate the power board, the owner is generally responsible for damages or
injuries that may occur. Owners must not allow any Third Party to operate the JetSurf™ without prior
instruction in correct use and operational risks. Owners are strongly encouraged to carry sucient
liability and property insurance to provide in anticipation of potential judgments in those instances.
Theft and on-shore damage are additional reasons to purchase insurance.
REFUSE AND POLLUTION
The U.S. Coast Guard* and/or relevant Authority which applies to the region where the JetSurf™ is
used provides detailed information regarding the disposal or refuse. In general, refuse, even bio-de-
gradable, should be disposed properly on-shore. If the user deduces that there are any substances
that could pollute waters leaking from the board, it should be presented to an authorised JetSurf™
dealer for repair. Pollution laws and regulations are stringent in most areas.
At no time should the power board owner and/or operator alter the engine exhaust system or fuel
system in any fashion. Doing so is both illegal and potentially dangerous.
* Valid for the USA

DFI003/EN_part A
OTHER SAFETY MATTERS
Riders should:
- Be at least sixteen (16) years old or the minimum age required within the jurisdiction in which the
power board is operated. The power board was designed to be operated by adults.
- Wear appropriate safety gear especially a Helmet and Life Vest and safety leash.
- Ensure the power board is in excellent condition and ready to operate in top form. Have sucient
fuel for the outing or gear the outing to the generally expected period of time that fuel will remain,
and be sure that the ignition battery is functional and well-charged to avoid becoming stranded away
from shore.
- Avoid operation during bad weather, including but not limited to, high winds, rain that obscures
vision, warnings of impending threatening weather, high waves, or any weather in which the rider
feels at all uncomfortable.
- Do not use the power board, if the air temperature is lower than 2°C.
- Avoid operation in water that is too shallow or is brackish.
Because the power board engine is water-jet pump pro-
pelled, weeds and other ora can foul the engine intake.
If it is suspected that fouling agents or small objects have
been brought into the pump/engine system (height of water
stream coming out of engine cooling system nozzle output
will get smaller or end completely), immediately cease oper-
ation and perform a typical maintenance operation to clean
the system.
- Maintain a speed and operational method that ensures the
rider can avoid collisions with objects (above and below the
waterline), buoys, docks, shorelines and other vessels.
- Know and practice navigational rules and regulations.
- Maintain an unobstructed view at all times, particularly in
the direction the power board is moving.
- Ride singularly on the power board. Multiple people on one
power board can overload it and cause it to sink. The power
board is built with anticipation of one (1) average-sized per-
son per board.
- Never exceed the highest loading capacity.
- In addition, it is necessary for the rider to maintain line-of-sight, which means there should never be
another person in front of the rider as the outing progresses.
- Not carry aboard any item. The power board requires the rider to maintain control via the control
handle. The rider should never be distracted from control of the power board.
- Always keep the engine shut-o key with kill switch Paracord around the wrist so that when the
rider goes overboard the engine will be immediately shut down.

SAFETY MATTERS
SAFE OPERATION ON THE WATER
Laws, rules, regulations and enforcement have been developed in North America and around the
world to ensure safe and proper operation of all watercraft. It is the responsibility of the owner and/
or operator to familiarize himself or herself with all applicable ordinances on the body of water upon
which the JetSurf™ power board will be operated. For operators in the United States, refer to the
website*: www.uscg.boating.org
In Canada, refer to the website**: www.tc.gc.ca/eng/marinesafety/menu.htm
Other countries have their own laws or participate in international rules. Always verify markings and
rules as they apply to any body of water on which operations will be conducted.
GENERAL PRUDENTIAL RULE
Rule 2 in the International Rules says, “In obeying and construing these rules due regard shall be
had to all dangers of navigation and collision, and to any special circumstances, which may
render a departure from the above rules necessary in order to avoid immediate danger.”
GENERAL EXPECTATIONS
Always use common sense when encountering other vessels. The power board is considered a pow-
ered watercraft and will be expected to give-way to non-powered vessels that have less maneuvera-
bility. The vessel that does not has the duty to take proper and timely action to sta out of the way of
the stand-on vessel. Normally, the give-way vessel should not cross in front of the stand-on vessel.
Always move in such a way that the stand-on operator can see the operation.
When encountering other powered vessels, there are three (3) main situations that could require
avoiding a collision:
- Meeting (approaching another vessel head on);
- Crossing (travelling across the other vessel’s path);
- Overtaking (passing or being passed by another vessel).
When meeting another vessel head on with the risk of collision, neither has right of way. Both vessels
must alter course to avoid an accident. Keep the other vessel on the port (left) side unless it is possi-
ble to clear each other by maintaining course.
When two (2) power-driven vessels cross paths with risk of collision, the vessel that views the crossing
vessel to the starboard (right) side must give way.
When overtaking, you are the give-way vessel. The other vessel is expected to maintain course and
speed. Avoid it as you clear it. When being passed by another vessel, maintain speed and direction
so that the passing vessel can clear.
In other circumstances, when preparing to go around a bend on a body of water, sound a prolonged
blast on a whistle for four (4) to six (6) seconds. Regardless of whether you hear a response, proceed
with caution.

Under normal operation situations, stationary shing and sailing boats (stationary or moving) are
given the right of way.
Always learn about and pay attention to buoys and other markers. The Uniform State Waterway
Marker System has been devised for interior waterways in the United States*. Markings may vary by
geographic location. Always consult appropriate authorities before using the power board in unfa-
miliar waters.
MEETING
When two boats are approaching
each other on the water, one has
the righta-way and is designated the
“stand-on” vessel. The other boat
must yield or give way and is desig-
nated the “give-way” vessel.
In illustration A, you are the JetSurf™
in the center. You are required to
yield to any vessel shown in the
white area (you are the “give-way”
vessel). Any vessels shown in the
shaded area must yield to you(you
are the “stand-on” vessel). If both
of you are heading directly toward
one another, illustration B, you both
must give way. You should turn right
to keep the approaching vessel to
your left or port side. This rule does
not apply if both vessels will be clear
of each other if you continue on
your set course and speed.
