E EJU00613 CRUISING LIMITATIONS EJX24011 8 Do not jump boat wakes or follow another boat or watercraft too closely. You increase your risk of colliding with another boat, which could result in severe injury or death. Do not jump waves, wakes, or any objects. You risk severe impact injuries. Jumping can also cause damage to the water vehicle. 8 Never ride in water that is less than 60 cm ( 2 feet ) deep. You increase your chance of hitting an underwater obstacle. You could be injured.
E EJU00616a OPERATIONAL REQUIREMENTS EJX16010 8 Operating your water vehicle requires skills acquired only through practice over a period of time. Take the time to learn the basic operating techniques well, before attempting more difficult maneuvers. EJX11211 8 Both operator and a passenger must always wear a U.S. Coast Guard approved personal flotation device (vest-type) because of the drowning hazards associated with water sports.
E A helmet may have potential safety hazard, as well. A helmet could catch the water during a fall into the water. This is commonly called “bucketing”. The resulting strain on your neck could cause choking, severe and permanent neck injuries, 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.
E 8 To prevent accidental starting of the engine, always remove the lock plate from the engine stop lanyard switch when the engine is not running. e w q 8 This water vehicle is included in the Class A inboard boat classification of the U.S. Coast Guard. A water craft of this type MUST carry a fire extinguisher of a B-1 classification, with a capacity of two pounds or more when navigating in waters under Coast Guard jurisdiction.
E EJU00314a WATER VEHICLE CHARACTERISTICS K1053 8 Jet thrust turns the water vehicle. If you are going faster than trolling speeds (the lowest maneuvering speed), you must use throttle to turn. If you release the throttle completely, you cannot turn-even if you turn the handlebars. Practice turning in an open area without obstructions until you have a good feel for this maneuver. 8 Yamaha Water Vehicles are water-jet propelled. The jet pump is directly connected to the engine.
E EJU00319 STEERING AND SAILING RULES AND SOUND SIGNALS RULES OF THE ROAD Your Yamaha water vehicle is legally considered a power boat. Operation of the water vehicle must be in accordance with the rules and regulations governing the waterway on which it is used. Just as there are rules which apply when you are driving on streets and highways, there are waterway rules which apply when you are riding your water vehicle.
E In other words, follow the standard rules except when a collision will occur unless both vessels try to avoid each other. If that is the case, both vessels become “Give-Way” vessels.
E 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. Sailing Vessel Right-of-Way Sailing vessels should normally be given the right-of-way. The exceptions to this are: 1. 2. 3.
E Remember, markings may vary by geographic location. Always consult local boating authorities before riding your water vehicle in unfamiliar waters. tion. These markers are white with black letters and orange boarders. They signify speed zones, restricted areas, danger areas, and general information.

Stop pouring when the oil just reaches the bottom of the filler tube. cC Do not allow the oil tank to empty completely. The oil injection pump must be bled to ensure proper oil flow after the tank empties. Otherwise, engine damage may occur.
E EJU00422 PRE-OPERATION CHECKS CHECK LIST Before operating this water vehicle, perform the following checks: w If any item in the Pre-Operation check is not working properly, have it inspected and repaired before operating the water vehicle. Otherwise an accident could occur. ITEM ENGINE COMPARTMENT BILGE ROUTINE Remove seats and front storage compartment, and ventilate the engine compartment. Check, and remove all water and fuel residue before launching.
E EJU00425a CHECK POINT Engine compartment Open the front hood and remove the storage compartment, and also remove the front seat for a few minutes to allow any fuel vapors to escape. GP7-068 w Failure to ventilate the engine compartment to release fuel vapors could result in fire or explosion. Do not start the engine if you can smell fuel vapors in the engine compartment. EJU00427 Fuel system Refer to page 4-10 “FUEL SYSTEM INSPECTION” for correct procedure.
E EJU00432a w q GU0-069 Water separator 1) Check the water separator to see if there is any water in this separator. This water separator retains any water entering through the fuel tank breather pipe if the Vehicle is capsized. Normally this water separator is empty. (No water) 2) If water remains in this water separator, drain it by removing the drain screw. Do not forget to reinstall the drain screw securely.
E EJU00435a Battery Check the battery condition and the battery electrolyte level. Check that the battery terminals are tightened securely and that there is no erosion. w The battery must always be fully charged and in good condition. Loss of battery power may leave you stranded. Never operate the water vehicle if the battery does not have sufficient power to start the engine or if it shows any other signs of decreased power.
E EJU00447 Throttle Operate the throttle lever several times to make sure there is no hesitation in its travel. It should be smooth over the complete range, and spring back to the idle position on its own when released. GP7-072 EJU00448 GU0-073 Steering Make sure the handlebars are not loose. Turn them full-right and full-left to make sure operation is smooth and unrestricted throughout the whole range.
E EJU00915a e q w GP7-074 Switches First, place the vehicle in the water to provide adequate engine cooling. Push the starter switch 1 and start the engine, then push the engine stop switch 2. Restart the engine and pull the engine stop switch lanyard on your left wrist to remove the lock plate 3 from the engine stop lanyard switch.

E EJU00455 OPERATION w Before operating your water vehicle, become familiar with all controls. Consult your Yamaha dealer about any control or function you do not fully understand. Failure to understand how controls work could cause an accident or prevent you from avoiding an accident. cC There are two hull drain plugs near the jet unit on the stern side. Be sure they are securely tightened before launching the Water Vehicle.
E 1) Launch the vehicle and start the engine. w Never ride in water that is less than 60 cm (2 feet) deep. You increase your chance of hitting an underwater obstacle. You could be injured. Operate at higher speeds only in deep water free of under water obstacles. 2) 3) 4) 5) Run the engine at the lowest possible speed for the first five minutes. Gradually open the throttle to 3/4 or less. Continue operation at 3/4 - throttle or less until the first tankful of fuel has been used up.
E EJU00461a STARTING THE ENGINE w This product emits exhaust gases which contain carbon monoxide, a colorless, odorless gas which may cause brain damage or death when inhaled. Symptoms include nausea, dizziness, and drowsiness. Operate the vehicle in a open area. 1) Always make sure the vehicle is launched and used in waters that are free from weeds and debris, and in depths of at least 60 cm (2 feet). w 60 cm (2 ft) GP7-077 Never ride in water that is less than 60 cm (2 feet) deep.
E e 3) q Attach the lock plate to the engine stop lanyard switch. Also, attach the lanyard to your left wrist. 1 Engine stop lanyard switch 2 Lanyard 3 Lock plate w GP7-079 w Check that the lanyard is not frayed or broken, wrapped around the handlebars, or tangled in controls. If the operator falls off, the vehicle could continue to run and cause an accident. The operator would also be unable to rebound the vehicle, which increases the chance of being hit by another boat and the risk of exposure.
E NOTE: 8 If initial setting of the PADLOC has not been done, the “START” mode is automatically selected. 8 If you have previously chosen “LOCK” mode, the engine will not start unless the right code is put in to select “START” mode. 6) While lightly squeezing the throttle lever, push the starter switch (green button). w On this vehicle, the engine is connected directly to the drive unit.

EJU00666a STOPPING THE ENGINE To stop the engine, release the throttle lever, then push and hold the engine stop switch (red button) with your left hand. When the red button is pushed the ignition stops, which stops the engine.
E EJU00466 EJU00472 RIDING YOUR WATER VEHICLE LEARNING TO RIDE YOUR WATER VEHICLE GETTING TO KNOW YOUR WATER VEHICLE Riding your water vehicle requires skills acquired through practice over a period of time. Take the time to learn the basic techniques well before attempting more difficult maneuvers. Riding your new water vehicle can be a very enjoyable activity, providing you with hours of pleasure.
E Wind, water, and glare from the sun may get in your eyes while you operate your water vehicle, reducing your ability to see. You may want to consider wearing eye protection such as sunglasses or goggles while riding. Some may find, however, that eye protection obstructs or distorts their vision, and distracts from operation. Only you know the circumstances in which you operate your water vehicle, so only you can decide if the benefits of eye protection outweigh the potential hazards.
E EJU00484 STARTING w 8 There may be other water craft, obstructions, or swimmers around you. Check carefully before starting off to avoid an accident. 8 Practice getting on board in shallow water before riding in deep water. EJU00486a 60cm(2 ft) KA021 KA022 Starting in shallow water 1) Do not start your water vehicle in less than 60 cm (2 feet) of water. Put it in an area that is deep enough, then board the vehicle from the side or the rear.
E EJU00490a BOARDING AND STARTING IN DEEP WATER w 8 Operator and passenger should practice getting on board in shallow water before riding in deep water. Reboarding in deep water requires more skill. 8 The fatigue and exposure that could result after unsuccessful attempts to get back on the vehicle may increase the risk of injuries and drowning. Solo 1) Swim to the rear of the vehicle and place both hands on the footrest floor. Pull yourself up on the floor and kneel down.
E EJU00492a With a passenger w K2011 Strong streams of water from the jet nozzle can be dangerous, and can result in injury when directed at body orifices (rectum and vagina). Do not open the throttle until each passenger is seated with feet on the floor and is holding on to the person in front of him or her. 1) Climb up on board as noted earlier, and sit astride the seat. Attach the lanyard to your left wrist, then install the lock plate to the engine stop lanyard switch.
E EJU00494a LOAD LIMIT K2021 The heavier the total weight of the operator and passenger, the more difficult it will be to balance the water vehicle. It is not advisable to ride the vehicle when the total weight exceeds 160 kg (353 lb) including any cargo. If it is difficult to balance the vehicle at a standstill, proceed as follows: 1) The passenger must steady the water vehicle while the operator is boarding.
E EJU00497a CAPSIZED WATER VEHICLE KA013 KA014 1) Turn off the engine by removing the lock plate from the engine stop lanyard switch. The engine will overheat when capsized because it has no water to pump as coolant. 2) Swim to the rear side of the vehicle. Pull the vehicle over clockwise with the left hand on the ride plate while pushing down on the gunwale with your right hand/foot. Do not turn the vehicle counterclockwise, or water may leak into the carburetor and engine.
E cC If the vehicle has been capsized for 5 minutes or more, air may have entered the oil injection system. Leave the engine off, or operate only at trolling speeds, for 10 minutes after the vehicle has been put right-side up. This will allow any air to bleed off. EJU00499 TURNING GU0-083 Throttle produces thrust from the jet pump. Directional control is provided by opening the throttle and turning the handlebars.
E EJU00634 STOPPING 115m (380 ft) GU0-085 The water vehicle is not equipped with a separate braking system. It is stopped by water resistance when the throttle lever is released. From full speed, the water vehicle stops in approximately 115 m (380 feet) after the throttle is released and the engine stopped. The stopping distance varies depending on gross weight, water surface conditions, and wind direction. The stated stopping distance should be used for a reference.
E 3) Get off the vehicle and pull it up on the beach. cC Small pebbles, sand, seaweed, and other debris can be ingested into the jet intake and impair or damage the impeller. Always stop the engine and get off before beaching the vehicle. EJU00505 DOCKING 1) 2) Make sure no obstructions, boats or swimmers are close to the water vehicle. Reduce speed about 115 m (380 ft) away from the dock. Slowly approach the dock and stop the engine just before coming alongside it.
E EJU00508a POST-OPERATION CHECKS 1) 2) 3) 4) GP7-070 After removing the vehicle from the water, put the vehicle in the horizontal position. Flush cooling system to prevent the cooling system from clogging up with salt, sand, or dirt. “Refer to pages 4-1 for the cooling system flushing procedure”. Lubricate the internal components by performing “LUBRICATION” at page 4-3, if storing the water vehicle for more than a week.
E 6) Raise the bow about 30 cm (12 in.) and remove two hull drain plugs. Allow any water in the bilge to drain out. Rinse the engine compartment with a small amount of fresh water. Be careful not to get water on the carburetor or electrical components. After the water has drained, wipe the bilge with dry rags. Reinstall two drain plugs. NOTE: This vehicle is equipped with an automatic bilge-draining device that removes water from the engine compartment while you are underway.
E EJU00513 TRANSPORTATION w GP7-086 Always place the fuel cock in the “OFF” position when transporting the water vehicle. Otherwise, fuel could leak out into the engine or engine compartment, which would create a fire hazard.
