USER MANUAL

Copyright 2016; All rights reserved

JetSurf™ motorized power boards were designed and manufactured by MotosurfWC and Formula 1 en-
gineers 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 interna-
tional/domestic carrier flights). 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 company 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 finest materials and components currently produced in the European Union are 
utilized. This comprehensive in-house production allows JetSurf™ to ensure themaximum precision and 
efficient production..

JetSurf™  power  boards  were  developed  with  exceptional  effort  to  minimize  environmental  impact. 
Through specialized and the most advanced technology, engineers have reduced the total weight of the 
JetSurf™ power board and accessories to forty point eight (40.8) pounds (eighteen and a half kilograms 
[+18.5]). JetSurf™ power boards meet homologation (registration for racing) standards for noise emis-
sions, as well as using an internal combustion engine that enforces the Greentech technology and com-
plies with the emission limits set for motor vessels. The complete drive unit is certified and approved by 
the European Commission and received the European Union label, CE. All this effort toward compliance 
with international standards has ensured that the power boards are also compliant with North American 
requirements for personal watercraft.

The information contained in this User Manual represents the most up-to-date product data available at 
the time of printing. Because JetSurf™ is committed to continuous product improvements and advance-
ment of technology, the company reserves the right to change the product, components, specifications 
or other aspects of the JetSurf™ motorized power board without advance notice or a requirement to 
equip previously produced JetSurf™motorized power boards with these changes. You can find current 
upgrades on the JetSurf™ websites (www.jetsurf.com). Check this website regularly.

This User Manual for Owners or Operators (hereafter referred to as the “User Manual”) cannot anticipate 
every circumstance involved in owning or operating the motorized power board. JetSurf™ strongly en-
courages owners and operators to regularly review the U.S. Coast Guard website (www.uscg.mil) or the 
relevant coast guard and/or authority regulating the laws pertaining to the use of personal watercraft 
with particular attention to information provided for personal watercraft. Also check JetSurf™ company’s 
website (www.jetsurf.com) for updates and product information. 

JetSurf™ provides the following information in the expectation of long and enjoyable ownership of this 
JetSurf™ motorized power board.

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 con-
struction category 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 manufacturer of the vessel or its representative. If you have the maintenance 
manual, please follow it during the vessel maintenance. 

Maintenance, fixing and adjustments of the vessel can only be made by trained and qualified per-
sons. Any adjustments which might affect 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 adjustments not approved by it. 

In some countries it is required to have qualification or certificate 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 demanding operation or bad handling. 

Each vessel, regardless how hard-wearing it is, can suffer 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 PER-
SONAL SWIMMING 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.
