Limitations on who may operate the watercraft

Yamaha recommends a minimum operator age of 16 years old. Adults must supervise use by minors. Know the operator age and training re- quirements for your state. A boating safety course is recommended and may be re- quired in your state. You can find local rules by contacting the United States Coast Guard (USCG), the National Association of State Boating Law Administrators, or your local Power Squadron.

This watercraft is designed to carry the op- erator only. Never have more than one per- son on the watercraft at any time.

EJU30762

Cruising limitations Scan constantly for people, objects, and

other watercraft. Be alert for conditions that limit your visibility or block your vision of others.

Operate defensively at safe speeds and keep a safe distance away from people, objects, and other watercraft.

Do not follow directly behind watercraft or other boats.

Do not go near others to spray or splash them with water.

Avoid sharp turns or other maneuvers that make it hard for others to avoid you or un- derstand where you are going.

Avoid areas with submerged objects or shallow water.

Take early action to avoid collisions. Re- member, watercraft and other boats do not have brakes.

Do not release the throttle lever when trying to steer away from objectsyou need throttle to steer. Always check throttle and steering controls before starting the water- craft.

Ride within your limits and avoid aggres- sive maneuvers to reduce the risk of loss of control, ejection, and collision.

This is a high performance boatnot a toy. Sharp turns or jumping wakes or waves can increase the risk of back/spinal injury

(paralysis), facial injuries, and broken legs, ankles, and other bones. Do not jump wakes or waves.

Do not operate the watercraft in rough wa- ter, bad weather, or when visibility is poor; this may lead to an accident causing injury or death. Be alert to the possibility of ad- verse weather. Take note of weather fore- casts and the prevailing weather conditions before setting out on your wa- tercraft.

As with any water sport, you should not op- erate your watercraft without someone else nearby. If you operate further than swim- ming distance from shore, you should be accompanied by another boat or water- craft, but make sure you stay a safe dis- tance away. Its good, common sense.

Never operate in water that is less than 60 cm (2 ft) deep from the bottom of the wa- tercraft, otherwise you increase your chan- ce of hitting a submerged object, which could result in injury.

This watercraft is not equipped with light- ing required for night operation. Do not op- erate the watercraft after sunset or before dawn, otherwise you increase the risk of

colliding with another boat, which could re- sult in severe injury or death.

Follow navigation rules, and state/provin- cial and local laws that apply to watercraft.

EJU30773

Operation requirements All riders must wear a personal flotation de-

vice (PFD) that is approved by the appro- priate authorities and is suitable for personal watercraft use.

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. Normal swimwear does not adequately protect against forceful water entry into the rectum or vagina. All riders must wear a wetsuit bottom or clothing that provides equivalent protection. Such clothing in- cludes thick, tightly woven, sturdy and snug-fitting apparel such as denim, but does not include spandex or similar fab- rics, like those used in bicycle shorts.

Eye protection is recommended to keep wind, water, and glare from the sun out of your eyes while you operate your water- craft. Restraining straps for eyewear are made which are designed to float should your eyewear fall in the water. Footwear and gloves are recommended.

Helmets meeting Snell or DOT standards are required for IJSBA-sanctioned races. You must decide whether to wear a helmet while you ride for recreation. You should

know that a helmet could help protect you 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 circum- stances, choose one carefully. Look for a helmet designed for personal watercraft use, if possible. Consider a helmet meeting Snell or DOT standards. If you will be en- gaging in closed-course competition, fol- low the helmet requirements of the sanctioning organization.

Never operate the watercraft after consum- ing alcohol or taking other drugs.

For reasons of safety and proper care of the watercraft, always perform the pre-op- eration checks listed on page 36 before op- erating the watercraft.

The operator should always keep both feet or knees on the riding tray when the water- craft is in motion. Lifting your feet increases the chances of losing your balance or hit- ting objects outside the watercraft with your feet.

Always consult your doctor on whether it is safe for you to operate this watercraft if you are pregnant or in poor health.

Do not attempt to modify this watercraft. Modifications to your watercraft may re- duce safety and reliability, and render the watercraft unsafe or illegal for use.

Attach the engine shut-off cord (lanyard) to your left wrist and keep it free from the han- dlebars so that the engine stops if you, the operator, fall off. After riding, remove the engine shut-off cord (lanyard) from the wa- tercraft to avoid accidental starting or un- authorized use by children or others.

Scan carefully for swimmers, and stay away from swimming areas. Swimmers are hard to see and you could accidentally hit someone in the water.

Avoid being hit by another boat. You should always take the responsibility to watch for traffic; other boaters may not be watching for you. If they do not see you, or if you maneuver more quickly than other boaters expect, you risk a collision.

Maintain a safe distance from other boats and watercraft, and also watch for ski ropes or fishing lines. Obey the Rules of the Road and be sure to check behind you before making a turn. (See Rules of the Road on page 14.)

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 boating laws also require that the fire extin- guisher be approved by the USCG.

Recommended equipment The following items should be carried on board your watercraft: Sound-signaling device

You should carry a whistle or other sound- signaling device that can be used to signal other boats. See Rules of the Road for more information.

Visual distress signals It is recommended that a U.S. Coast Guard approved pyrotechnic device be stored in a waterproof container on your watercraft. A mirror can also be used as an emergency signal. Contact a Yamaha dealer or the U.S. Coast Guard for more information.

Watch A watch is helpful so you will know how long you have been operating the water- craft.

Towline A towline can be used to tow a disabled watercraft in an emergency.

EJU30851

Hazard information When transporting or storing your water-

craft, always turn the fuel cock knob to OFF, otherwise gasoline may overflow from the carburetor.

Never start the engine or let it run for any length of time in an enclosed area. Exhaust fumes contain carbon monoxide, a color- less, odorless gas that may cause loss of consciousness and death within a short time. Always operate the watercraft in an open area.

Watercraft characteristics Jet thrust turns the watercraft. Releasing

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. You may still have some turning ability im- mediately after releasing the throttle lever, but once the engine slows down, the wa- tercraft will no longer respond to handlebar 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.

This watercraft is water-jet propelled. The jet pump is directly connected to the en- gine. This means that jet thrust will produce some movement whenever the engine is running. There is no neutral position.

Keep away from the intake grate while the engine is on. Items such as long hair, loose clothing, or PFD straps can become entan- gled in moving parts, resulting in severe in- jury or drowning.

Never insert any object into the jet thrust nozzle while the engine is running. Severe injury or death could result from coming in

contact with the rotating parts of the jet pump.

Stop the engine and remove the clip from the engine shut-off switch before removing any debris or weeds, which may have col- lected around the jet intake.

Avoid forceful jet thrust and limited visibility while reboarding. Get to a standing or kneeling position quickly, but do not ex- pose yourself to the forceful jet thrust.

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.

Give-way vessel The vessel which does not have the right-of- way has the duty to take positive and timely action to stay out of the way of the stand-on vessel. Normally, you should not cross in front of the vessel with the right-of-way. You should slow down or change directions brief- ly and pass behind the other vessel. You should always move in such a way that the operator of the other vessel can see what you are doing. The General Prudential Rule regarding the right-of-way is that if a collision appears un- avoidable, neither boat has the right-of-way. Both boats must avoid the collision. In other words, follow the standard rules ex- cept when a collision will occur unless both vessels try to avoid each other. If that is the case, both vessels become give-way ves- sels. Rules when encountering vessels There are three main situations that you may encounter with other vessels which could lead to a collision unless the Steering Rules are followed: Meeting: you are approaching another vessel head-on Crossing: you are traveling across another vessels path Overtaking: you are passing or being passed by another vessel In the following illustration, your watercraft is in the center. You should give the right-of- way to any vessels shown in the white area (you are the give-way vessel). Any vessels in the shaded area must yield to you (they are the give-way vessels). Both you and the

UF4D14E0.book Page 14 Tuesday, March 27, 2018 1:02 PM

15

meeting vessel must alter course to avoid each other.

Meeting If you are meeting another power-driven ves- sel head on, and are close enough to run the risk of collision, neither of you has the right- of-way. Both of you should alter course to avoid an accident. You should keep the other vessel on your port (left) side. This rule does not apply if both of you will clear one another if you continue on your set course and speed.

Crossing When two power-driven vessels are crossing each others path close enough to run the risk of collision, the vessel which has the other on the starboard (right) side must keep out of the way of the other. If the other vessel is on your starboard (right) side, you must keep out of its way; you are the give-way vessel. If the other vessel is on your port (left) side, remem- ber that you should maintain course and di-

rection, provided the other vessel gives you the right-of-way as it should.

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.

16

Fishing vessel right-of-way All vessels fishing with nets, lines, or trawls are considered to be fishing vessels under the International Rules. Vessels with trolling lines are not considered fishing vessels. Fish- ing vessels have the right-of-way regardless of position. Fishing vessels cannot, however, impede the passage of other vessels in nar- row channels. Sailing vessel right-of-way Sailing vessels should normally be given the right-of-way. The exceptions to this are: (1) When the sailing vessel is overtaking the

power-driven vessel, the power-driven vessel has the right-of-way.

(2) Sailing vessels should keep clear of any fishing vessel.

(3) In a narrow channel, a sailing vessel should not hamper the safe passage of a power-driven vessel that can navigate only in such a channel.

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.

Many bodies of water used by boaters are entirely within the boundaries of a particular state. The Uniform State Waterway Marking System has been devised for these waters. This system uses buoys and signs with dis- tinctive shapes and colors to show regulatory or advisory information. These markers are white with black letters and orange borders.

They signify speed zones, restricted areas, danger areas, and general information.

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

Enjoy your watercraft responsibly

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.

When you ride responsibly, with respect and courtesy for others, you help ensure that our waterways stay open for the enjoyment of a variety of recreational opportunities.

proper operation of the cooling system, make sure that water is being discharged from the cooling water pilot outlet. If water is not being discharged from the outlet, stop the engine and check the jet intake for clogging. (See page 70 for information on the jet intake.)

TIP: It will take about 20 seconds for the water

to reach the outlet after the engine is start- ed.

Water discharge may not be constant when the engine is running at idling speed. If this occurs, apply a little throttle to make sure that water discharges properly.

EJU40323

Water separator The water separator prevents water from en- tering the fuel tank by collecting any water that has entered the fuel tank breather hose if the watercraft was capsized. If water has collected in the water separator, drain it by loosening the drain screw.

To drain water from the water separator: (1) Place a drain pan or dry cloth under the

water separator. (2) Gradually loosen the drain screw to drain

the water. Catch the draining water in the drain pan or soak it up with the dry cloth so that it does not spill into the engine compartment. If any water spills into the

watercraft, be sure to wipe it up with a dry cloth.

(3) Securely tighten the drain screw until it stops.

EJU31665

Engine overheat warning system If the engine temperature rises significantly, the engine overheat warning system will acti- vate and the engine speed will be limited to about 3400 r/min to help prevent damage. If the engine overheat warning system is acti- vated, immediately reduce the engine speed, return to shore, and then make sure that wa- ter is being discharged from the cooling wa- ter pilot outlet while the engine is running. If there is no discharge of water, stop the en- gine, and then check the jet intake for clog- ging. (See page 70 for information on the jet intake.) NOTICE: If you cannot locate and correct the cause of the overheating, con- sult a Yamaha dealer. Continuing to oper- ate at higher speeds could result in severe engine damage. [ECJ00042]

Fuel

WARNING EWJ00283

Gasoline and gasoline vapors are ex- tremely flammable. To avoid fires and explosions and to reduce the risk of in- jury when refueling, follow these in- structions.

Gasoline is poisonous and can cause in- jury or death. Handle gasoline with care. Never siphon gasoline by mouth. If you should swallow some gasoline, inhale a lot of gasoline vapor, or get some gaso- line in your eyes, see your doctor imme- diately. If gasoline spills on your skin, wash with soap and water. If gasoline spills on your clothing, change your clothes.

NOTICE ECJ00322

Do not use leaded gasoline. Leaded gasoline can seriously damage the en- gine.

Avoid getting water and contaminants in the fuel tank. Contaminated fuel can cause poor performance and engine damage. Use only fresh gasoline that has been stored in clean containers.

Gasohol There are two types of gasohol: gasohol con- taining ethanol and that containing methanol.

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. EJU31873

2-stroke engine oil

If YAMALUBE 2-W engine oil is not available, another 2-stroke engine oil with an NMMA- certified TC-W3 rating may be used. EJU31903

Mixing fuel and oil

NOTICE ECJ00332

Make sure that the gasoline and oil are thoroughly mixed in the correct ratio, oth- erwise severe engine damage could re- sult.

To mix gasoline and engine oil: (1) Pour 2-stroke engine oil into a clean con-

tainer, and then add gasoline.

Recommended fuel: Regular unleaded gasoline with a mi- nimum octane rating of

86 (Pump octane number) = (R + M)/2 90 (Research octane number)

Recommended engine oil: YAMALUBE 2-W or TC-W3 outboard motor oil or equivalent

Filling the fuel tank To fill the fuel tank: (1) Before refueling, stop the engine. Do not

stand or sit on the watercraft. Never refu- el while smoking, or while in the vicinity of sparks, open flames, or other sources of ignition.

(2) Place the watercraft in a well-ventilated area and in a horizontal position.

(3) Remove the hood, and then check the fuel level. (See page 27 for hood removal and installation procedures.)

(4) Loosen the fuel filler cap and remove it.

(5) Slowly add fuel to the fuel tank.

(6) Stop filling when the fuel level just reach- es the bottom of the filler tube. Do not fill up the filler tube. Because fuel expands when it heats up, heat from the engine or the sun can cause fuel to spill out of the fuel tank. Do not leave the watercraft with a full tank in direct sunlight.

(7) Wipe up any spilled fuel immediately with a dry cloth.

(8) Securely install the fuel filler cap by tight- ening it until it clicks.

(9) Securely install the hood in its original position.

WARNING EWJ00511

Before operating your watercraft, become familiar with all of the controls. Consult a Yamaha dealer about any control or func- tion that you do not fully understand. Fail- ure to understand how the controls work could cause an accident or prevent you from avoiding an accident.

EJU32916

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 7. Also, watch the WaveRunner Basic Orientation Video linked to the following QR code.

https://yamahawaverunners.com/orientation A DVD is also available your nearest dealer for your convenience. These materials should give you an under- standing of the watercraft and its operation. Remember: This watercraft is designed to carry the operator only. Never have more than one person on the watercraft at any time. EJU32975

Learning to operate your watercraft Before operating the watercraft, always per- form the pre-operation checks listed on page 36. The short time spent checking the water- craft will reward you with added safety and reliability. Check state and local laws before operating your watercraft. Operate defensively at safe speeds and keep a safe distance away from people, objects, and other watercraft. Select a wide area to practice maneuvering in, where there is good visibility and light boat traffic.

Use the buddy systemoperate with some- one nearby. Scan constantly for people, ob- jects, and other watercraft. Be alert for conditions that limit your visibility or block your vision of others. You should grip the handlebars firmly and get to a standing or kneeling position quickly. Keep both feet or knees on the riding tray when the watercraft is in motion.

Operating positions After you are underway, you may choose to kneel or stand, depending upon watercraft speed, your skill level, and your preference. Here are some guidelines. Kneeling It is easier to maintain your balance when kneeling than when standing. This position is recommended when traveling at sub-planing speeds. (At sub-planing speeds, there is a wake, but the watercraft is moving through the water rather than skimming on top of it.)

At very slow speeds, it may be necessary to support your upper-body weight with your el- bows resting on the gunwales, trailing your legs in the water. Standing After you are comfortable handling the water- craft from a kneeling position, try standing as the watercraft gains speed. The watercraft will become easier to balance as the speed increases, because jet thrust provides stabil- ity as well as directional control. When you are moving slowly, or preparing to stop, you

will probably need to return to the kneeling position to maintain your balance.

EJU32822

Launching the watercraft When launching the watercraft, make sure that there are no obstacles around you. If the watercraft is launched from a trailer, someone should make sure that waves do not push the watercraft into the trailer. After the watercraft is in the water, turn it around so that the bow faces the direction you wish to go. EJU32836

Starting the engine on water

WARNING EWJ01521

Do not apply throttle when others are at the rear of the watercraft. Turn the engine off or keep it at idle. Water and debris ex- iting the jet thrust nozzle can cause severe injury.

To start the engine: (1) Move the watercraft to an area that is

free from weeds and debris, and has a water depth of at least 60 cm (2 ft) from the bottom of the watercraft. NOTICE: Never run the engine in water that is less than 60 cm (2 ft) deep from the bottom of the watercraft, otherwise pebbles or sand could be sucked into

Turning the watercraft

WARNING EWJ00762

Do not release the throttle lever when trying to steer away from objectsyou need throttle to steer. A collision could result in severe injury or death.

When operating at higher speeds, make gradual turns or slow down before turn- ing. Sharp high-speed turns may cause the watercraft to slide sideways or spin, throwing the operator overboard, which could cause an injury.

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

the watercraft will turn more sharply.

B. Less throttle produces lower thrust, so the watercraft will turn more gradually.

C. Releasing 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. You may still have some turning ability immediately after re- leasing the throttle lever, but once the engine slows down, the watercraft will no longer respond to handlebar input until you apply throttle again or you reach trolling speed. At trolling speed, the watercraft can be turned gradually by handlebar position alone using just the amount of thrust available at idle.

D. If the engine is stopped while riding, there is no thrust. The watercraft will go straight even though the handlebars are turned.

You need throttle to steer. To maintain your balance, lean into a turn. How much you lean depends on the sharp- ness of the turn and your traveling speed. In

general, the higher the speed or the sharper the turn, the more you lean.

EJU33273

Stopping the watercraft The watercraft is not equipped with a sepa- rate braking system. It is stopped by water resistance when the throttle lever is released. From full speed, the watercraft comes to a complete stop in approximately 90 m (300 ft) after the throttle lever is released or the en- gine is stopped, although this distance will vary depending on many factors, including gross weight, water surface conditions, and wind direction. The watercraft slows down as soon as the throttle lever is released, but will coast for a distance before fully stopping. If you are not sure you can stop in time before

hitting an obstacle, apply throttle and turn in another direction.

WARNING EWJ00723

Allow adequate stopping distance. Take early action to avoid collisions. Re-

member, watercraft and other boats do not have brakes.

Operate defensively at safe speeds and keep a safe distance away from people, objects, and other watercraft to give you time to stop.

Do not shut the engine off when slowing down in case you need engine power to steer away from a boat or other obstacle that comes into your path.

WARNING EWJ00633

Avoid forceful jet thrust and limited visibil- ity while reboarding. Get to a standing or kneeling position quickly, but do not ex- pose yourself to the forceful jet thrust.

NOTICE ECJ01341

Never run the engine in water that is less than 60 cm (2 ft) deep from the bottom of the watercraft, otherwise pebbles or sand could be sucked into the jet intake, caus- ing impeller damage and engine overheat- ing.

The watercraft is less stable when at a stand- still or at a slow speed. It takes skill to keep the watercraft upright when starting. To stabilize the watercraft when accelerating to planing speed, maintain a low center of

gravity by operating it in the kneeling posi- tion. Even though it is easier to start in shallow wa- ter, you must learn deep-water boarding first. You will inevitably fall off, so be sure you know how to get back on the watercraft once you are away from shore. EJU33105

Boarding and starting in shallow water Be sure to learn the deep-water starting method before operating the watercraft in water where it is too deep for you to stand. (See page 51 for the deep-water starting method.) (1) Launch the watercraft in water free from

weeds and debris and at least 60 cm (2 ft) deep from the bottom of the water- craft. NOTICE: Never run the engine in water that is less than 60 cm (2 ft) deep from the bottom of the water- craft, otherwise pebbles or sand could be sucked into the jet intake, causing impeller damage and engine over- heating. [ECJ00473]

(2) Attach the engine shut-off cord (lanyard) to your left wrist, and then attach the clip to the engine shut-off switch.

(3) Grip the handlebars with both hands. Place one knee on the riding tray and ba- lance there.

(4) Look in all directions, start the engine, and then begin to accelerate.

(5) Pull your other knee up onto the riding tray as the watercraft speed increases.

(6) Move as far forward as possible without interfering with the movement of the han- dlebars. Keep your body perpendicular to the water, with your weight forward and low.

TIP: The watercraft will become easier to balance as the speed increases, because jet thrust provides stability as well as directional con- trol. EJU33125

Boarding and starting in deep water

WARNING EWJ01261

Be sure the operator 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 fa- tigued and suffer from exposure, increas- ing the risk of injury and drowning.

(1) Swim to the rear of the watercraft. Attach the engine shut-off cord (lanyard) to your

left wrist, and then attach the clip to the engine shut-off switch.

(2) Grip the handlebars with both hands. Pull your body up onto the riding tray and balance there, using your elbows on the gunwales for leverage.

(3) Look in all directions, start the engine, and then begin to accelerate.

(4) Continue to pull your body up onto the watercraft as the watercraft speed in- creases.

(5) Bring your knees up onto the riding tray and change to a kneeling position as soon as you can do so.

(6) Move as far forward as possible without interfering with the movement of the han- dlebars. Keep your body perpendicular to the water, with your weight forward and low.

(7) Once the bow drops, and the watercraft has leveled out in the water and reached planing speed, back off the throttle and select your desired speed.

TIP: The watercraft will become easier to balan-

ce as the speed increases, because jet thrust provides stability as well as direc- tional control.

It will take longer for a heavy operator to reach planing speed than it will for a light operator.

Capsized watercraft

WARNING EWJ00672

Improper uprighting can cause injury. Be sure to shut the engine off by pulling

on the engine shut-off cord (lanyard) to remove the clip from the engine shut-off switch.

Do not put your hands in the intake grate.

If the watercraft capsizes, turn it over imme- diately. To upright the watercraft: (1) Remove the clip from the engine shut-off

switch. (2) Swim to the rear of the watercraft. Turn

the watercraft over clockwise. If the port (left) side of the capsized wa- tercraft is tilting up, push down on the gunwale so that the port (left) side is down before turning the watercraft clockwise. NOTICE: Do not turn the watercraft over counterclockwise, otherwise water can enter the engine, which can result in severe damage. [ECJ00542]

(3) Slowly approach the beach and stop the engine just before reaching land. WARNING! You need throttle to steer. Shutting the engine off can cause you to hit an obstacle you are attempting to avoid. A collision could result in se- vere injury or death. [EWJ00602] NOTICE: Never run the engine in water that is less than 60 cm (2 ft) deep from the bottom of the watercraft, otherwise pebbles or sand could be sucked into the jet intake, causing impeller dam- age and engine overheating. [ECJ00473]

(4) Get off the watercraft and pull it up on the beach.

EJU37194

Operating in weeded areas Always avoid using your watercraft in areas where weed growth is thick. If operating in weeded areas is unavoidable, alternately squeeze the throttle lever and relax your grip on the throttle lever to vary the engine speed. Weeds tend to become clogged more when operating at a steady speed and at trolling speed. If weeds may have clogged the intake

area, clean the jet intake. (See page 70 for in- formation on the jet intake.) EJU41061

Checking the spark plugs

WARNING EWJ00351

Be careful not to damage the insulator when removing or installing a spark plug. A damaged insulator could allow sparks to escape, which could result in a fire or ex- plosion.

Remove and check the condition of the spark plugs. The condition of a spark plug can indicate something about the condition of the engine. For example, if the center electrode portion is very white, this could indicate an intake air leak or carburetion problem in that cylinder. Do not attempt to diagnose any problems yourself. Have a Yamaha dealer service the watercraft. To remove a spark plug: (1) Remove the hood. (See page 27 for hood

removal and installation procedures.) (2) Remove the spark plug cap. (3) Remove the spark plug, and then check

the condition of the spark plug and the spark plug gap. If the electrode portion is significantly discolored, if electrode ero- sion becomes excessive, if carbon and other deposits are excessive, or if the spark plug gap is not within the specified range, replace the spark plug.

TIP: When the engine is operating normally, the color of the spark plug electrode portion will be a medium-to-light tan.

To install a spark plug: (1) Wipe off any dirt from the threads, insu-

lator, and gasket surface of the spark plug.

(2) Install the spark plug, and then tighten it to the specified torque.

TIP: If a torque-wrench is not available when you are reinstalling a spark plug, a good estimate of the correct torque is 1/12 turn past finger- tight. When you are installing a new spark plug, a good estimate of the correct torque is 1/2 to 2/3 turn past finger-tight. (3) Wipe off any water or dirt inside the

spark plug cap.

sary technical knowledge, poor engine performance and damage may result.

The carburetor is a vital part of the engine and requires very sophisticated adjustments. Most adjustments should be left to a Yamaha dealer who has the professional knowledge and experience to make them. However, the operator may adjust the engine idling speed as part of the usual maintenance routine. EJU34472

Adjusting the engine idling speed (1) Place the watercraft in the water. (2) Start the engine and warm it up for 1 to 2

minutes. (3) While using a diagnostic tachometer,

turn the throttle stop screw to adjust the engine idling speed to specification. Turn the throttle stop screw clockwise to in- crease the engine idling speed or coun- terclockwise to decrease the engine idling speed.

Emergency procedures EJU34635

Cleaning the jet intake and impeller

WARNING EWJ00783

Before attempting to remove weeds or de- bris from the jet intake or impeller area, shut the engine off and remove the clip from the engine shut-off switch. Severe in- jury or death could result from coming in contact with the rotating parts of the jet pump.

If weeds or debris gets caught in the jet intake or impeller, cavitation can occur, causing jet thrust to decrease even though engine speed rises. If this condition is allowed to continue, the engine will overheat and may seize. NOTICE: If weeds or debris gets caught in the jet intake, do not operate the water- craft above trolling speed until they have been removed. [ECJ00654]

If there is any sign that the jet intake or impel- ler is clogged with weeds or debris, return to shore and check the intake and impeller. Al-

ways stop the engine before beaching the watercraft.

(1) Place a suitable clean cloth or carpeting underneath the watercraft to protect it from abrasions and scratches. Turn the watercraft on its side as shown. NOTICE: Always turn the watercraft over onto its port (left) side. When turning the watercraft on its side, sup- port the bow so that the handlebars are not bent or damaged. [ECJ00662]
