EX Deluxe: Take early action to avoid colli- sions... Remember, watercraft and other boats do not have brakes... In addition, the Reverse with Intuitive Deceleration Elec- tronics (RiDE) system is not a braking de- vice for avoiding dangerous situations... The RiDE system is an electronic system for controlling the engine speed and reverse gate, which is located near the jet thrust nozzle... The RiDE lever located at the left

Page 19

Wear protective clothing... Severe internal injuries can occur if water is forced into body cavities as a result of falling into the water or being near the jet thrust nozzle... You must wear shorts with neoprene (wet- suit material) to keep water from being forcefully injected into the rectum or vagina during a fall backward... Riders not wearing neoprene shorts have received severe rec- tal, vaginal, and internal injuries resulting in permanent damage... Normal swimwear does not offer adequate protection...

Page 20

in certain kinds of accidents and that it could injure you in others... A helmet is designed to provide some head protection... Although helmets cannot pro- tect against all foreseeable impacts, a hel- met might reduce your injuries in a collision with a boat or other obstacle... A helmet may have potential safety haz- ards, as well... Falling into the water could risk the chance of the helmet catching wa- ter, commonly known as bucketing, and the resulting strain on your neck could cau- se choking, severe and permanent neck in- juries, or death... A helmet could also increase the risk of an accident if it reduces your vision or hearing, or if it distracts you or increases your fatigue... How should you decide if a helmets poten- tial safety benefits outweigh its potential risks for you? Consider your particular rid- ing conditions... Consider factors such as your riding environment and your riding style and ability... Also consider the likeli- hood of traffic congestion, and the water surface conditions... If you decide to wear a helmet based upon your riding circumstances, choose one carefully... Look for a helmet designed for personal watercraft use, if possible... Con- sider a helmet meeting Snell or DOT stan- dards... If you will be engaging in closed- course competition, follow the helmet re- quirements of the sanctioning organization...

Page 21

According to the USCG, boats under 6... 1 m (20 ft) in length like your watercraft must carry a fire extinguisher of a B-1 classifica- tion, with a capacity of two pounds or more when navigating in waters under USCG ju- risdiction... In addition, most state and local

Page 22

Do not place magnets or objects with a strong magnetic force near the throttle le- ver or RiDE lever (EX Deluxe)... The electron- ic throttle mechanism of the levers can be adversely affected, which could cause loss of control... In addition, do not place objects susceptible to magnetic forces (i... e... , credit cards, watches, etc... ) close to the throttle lever or RiDE lever...

Page 23

the throttle lever completely produces only minimum thrust... If you are traveling at speeds above trolling, you will have rapidly decreasing ability to steer without throttle... This model is equipped with the Yamaha Engine Management System (YEMS) that includes an off-throttle steering (OTS) sys- tem... It will activate at planing speeds should you attempt to steer the watercraft after releasing the throttle lever... The OTS system assists in turning by continuing to supply some thrust while the watercraft is decelerating, but you can turn more sharp- ly if you apply throttle while turning the han- dlebars... The OTS system does not function below planing speeds or when the engine is off... Once the engine slows down, the water- craft will no longer turn in response to han- dlebar input until you apply throttle again or you reach trolling speed... Practice turning in an open area without obstacles until you have a good feel for this maneuver...

Page 24

It is the watercraft operators responsibility to be alert to the safety of the wakeboarder or water-skier and others... Know and follow all state and local regulations in effect for the waters in which you will be operating... The operator should be comfortable carrying passengers before attempting to pull a wake- boarder or water-skier... The following are some important consider- ations for minimizing risks while pulling a wakeboarder or water-skier... The wakeboarder or water-skier should

Page 25

A second person should be on board as a spotter to watch the wakeboarder or wa- ter-skier; in most states it is required by law... Let the person being pulled direct the operators control of speed and direction with hand signals... The spotter should sit astride the rear of the seat and hold onto the handgrip with both feet firmly on the floor of the footwell for proper balance while facing to the rear to watch the wakeboarders or water-skiers hand signals and condition...

Rules of the Road Your Yamaha watercraft is legally consid- ered a powerboat... Operation of the water- craft must be in accordance with the rules and regulations governing the waterway on which it is used... Just as there are rules that apply when you are driving on streets and highways, there are waterway rules that apply when you are oper- ating your watercraft... These rules are used internationally, and are also enforced by the United States Coast Guard and local agen- cies... You should be aware of these rules, and follow them whenever you encounter another vessel on the water... Several sets of rules prevail according to geographic location, but are all basically the same as the International Rules of the Road... The rules presented here in this owners/op- erators manual are condensed, and have been provided for your convenience only... Consult your local U... S... Coast Guard Auxiliary or Department of Motor Vehicles for a com- plete set of rules governing the waters in which you will be operating your watercraft... Steering and sailing rules Whenever two vessels on the water meet one another, one vessel has the right-of-way; it is called the stand-on vessel... The vessel that does not have the right-of-way is called the give-way or burdened vessel... These rules determine which vessel has the right-of-way, and what each vessel should do... Stand-on vessel The vessel with the right-of-way has the duty to continue its course and speed, except to avoid an immediate collision... When you maintain your direction and speed, the other vessel will be able to determine how best to avoid you...

Page 27

Overtaking If you are passing another vessel, you are the give-way vessel... This means that the other vessel is expected to maintain its course and speed... You must stay out of its way until you are clear of it... Likewise, if another vessel is passing you, you should maintain your speed and direction so that the other vessel can steer itself around you... Other special situations There are three other rules you should be aware of when riding your watercraft around other vessels... Narrow channels and bends When navigating in narrow channels, you should keep to the right when it is safe and practical to do so... If the operator of a power- driven vessel is preparing to go around a bend that may obstruct the view of other wa- ter vessels, the operator should sound a pro- longed blast of four to six seconds on the whistle... If another vessel is around the bend, it too should sound the whistle... Even if no re- ply is heard, however, the vessel should still proceed around the bend with caution... If you navigate such waters with your watercraft, you will need to carry a portable air horn, available from local marine supply stores...

Page 28

Reading buoys and other markers The waters of the United States are marked for safe navigation by the lateral system of buoyage... Simply put, buoys and markers have an arrangement of shapes, colors, num- bers, and lights to show which side of the buoy a boater should pass on when navigat- ing in a particular direction... The markings on these buoys are oriented from the perspec- tive of being entered from seaward (the boat- er is going towards the harbor)... Red buoys are passed on your starboard (right) side when proceeding from open water into the harbor, and black buoys are to your port (left) side... An easy way to remember the meaning of the colors is the phrase red right return- ing... When navigating out of the harbor, your position with respect to the buoys should be reversed; red buoys should be to port and black buoys to starboard...

Page 29

Remember, markings may vary by geograph- ic location... Always consult local boating au- thorities before riding your watercraft in unfamiliar waters...

You share the areas you enjoy when riding your watercraft with others and with nature... So your enjoyment includes a responsibility to treat these other people, and the lands, waters, and wildlife with respect and courte- sy... Whenever and wherever you ride, think of yourself as the guest of those around you... Remember, for example, that the sound of your watercraft may be music to you, but it could be just noise to others... And the exciting splash of your wake can make waves others wont enjoy... Avoid riding close to shoreline homes and waterfowl nesting areas or other wildlife ar- eas, and keep a respectful distance from fish- ermen, other boats, swimmers, and populated beaches... When travel in areas like these is unavoidable, ride slowly and obey all laws... Proper maintenance is necessary to ensure that the exhaust emission and sound levels of your watercraft will continue to be within reg- ulated limits... You have the responsibility to make sure that the recommended mainte- nance in this owners/operators manual is carried out... Remember, pollution can be harmful to the environment... Do not refuel or add oil where a spill could cause damage to nature... Remove your watercraft from the water and move it away from the shoreline before refueling... Dis- pose of water and any fuel and oil residue in the engine compartment according to local regulations... And keep your surroundings pleasant for the people and wildlife that share the waterways: dont litter...

Since the strength of the jet thrust determines the speed and degree of a turn, throttle must always be applied when attempting a turn, except at trolling speed... This model is equipped with the Yamaha En- gine Management System (YEMS) that in- cludes an off-throttle steering (OTS) system... It will activate at planing speeds should you attempt to steer the watercraft after releasing the throttle lever... The OTS system assists in turning by continuing to supply some thrust while the watercraft is decelerating, but you can turn more sharply if you apply throttle while turning the handlebars... The OTS sys- tem does not function below planing speeds or when the engine is off... Once the engine slows down, the watercraft will no longer turn in response to handlebar input until you apply throttle again or you reach trolling speed...

Gasohol containing ethanol can be used if ethanol content does not exceed 10% and the fuel meets the minimum octane ratings... E-85 is a fuel blend containing 85% ethanol and therefore must not be used in this water- craft... All ethanol blends containing more than 10% ethanol can cause fuel system damage or engine performance problems... Yamaha does not recommend gasohol con- taining methanol because it can cause fuel system damage and engine performance problems... To fill the fuel tank: (1) Before refueling, stop the engine... Do not

Page 57

(6) Stop filling when the fuel level reaches approximately 50 mm (2 in) from the top of the fuel tank... Do not overfill the fuel tank... Because fuel expands when it heats up, heat from the engine or the sun can cause fuel to spill out of the fuel tank...

Why Yamalube YAMALUBE oil is a Genuine YAMAHA Part born of the engineers passion and belief that engine oil is an important liquid engine com- ponent... We form teams of specialists in the fields of mechanical engineering, chemistry, electronics and track testing, and have them develop the engine together with the oil it will use... Yamalube oils take full advantage of the base oils qualities and blend in the ideal ba- lance of additives to make sure the final oil clears our performance standards... Thus, Yamalube mineral, semisynthetic and syn- thetic oils have their own distinct characters and value... Yamahas experience gained over many years of research and development into oil since the 1960s helps make Yamalube the best choice for your Yamaha engine...

Getting to know your watercraft Operating your watercraft requires skills ac- quired through practice over a period of time... Take the time to learn the basic techniques well before attempting more difficult maneu- vers... Operating your new watercraft can be a very enjoyable activity, providing you with hours of pleasure... However, it is essential to familiar- ize yourself with the operation of the water- craft to achieve the skill level necessary to enjoy riding safely... Before operating this watercraft, read this owners/operators manual, the Riding Prac- tice Guide, the Riding Instruction card, and all labels on the watercraft... Pay particular atten- tion to the safety information beginning on page 11... Also, watch the WaveRunner Basic Orientation Video linked to the following QR code...

Page 77

Steering control depends on the combination of handlebar position and the amount of throttle... Water sucked in through the intake grate is pressurized by the impeller in the jet pump... As the pressurized water is expelled from the pump through the jet thrust nozzle, it creates thrust to move and steer the watercraft... The higher the engine speed, the more thrust pro- duced... The amount of jet thrust, in addition to the po- sition of the handlebars, determines how sharply you turn... A... More throttle produces higher thrust, so

Page 78

This model is equipped with the Yamaha En- gine Management System (YEMS) that in- cludes an off-throttle steering (OTS) system... It will activate at planing speeds should you attempt to steer the watercraft after releasing the throttle lever (see condition C above)... The OTS system assists in turning by con- tinuing to supply some thrust while the water- craft is decelerating, but you can turn more sharply if you apply throttle while turning the handlebars... The OTS system does not func- tion below planing speeds or when the en- gine is off... Once the engine slows down, the watercraft will no longer turn in response to handlebar input until you apply throttle again or you reach trolling speed... EJU44371

Page 79

From full speed, the watercraft comes to a complete stop due to water resistance in ap- proximately 90 m (300 ft) after the throttle le- ver is released or the engine is stopped, although this distance will vary depending on many factors, including gross weight, water surface conditions, and wind direction...

Page 80

Be sure the operator and any passengers have practiced boarding from the water while still close to shore before riding... A person who has made many unsuccessful attempts to get back on the watercraft may become fatigued and suffer from ex- posure, increasing the risk of injury and drowning...

Page 81

Severe internal injuries can occur if wa- ter is forced into body cavities as a re- sult of being near the jet thrust nozzle... Do not start the engine until the passen- gers are seated with their feet on the floor of the footwell and are securely
