    EJU01041 Fuel and oil This engine uses Yamaha’s oil injection system, which provides superior lubrication by ensuring the proper oil ratio for all operat- ing conditions. No fuel premixing is neces- sary except during the engine break-in period. Simply pour gasoline into the fuel tank and oil into the oil tank.

  • Page 47: 2-Stroke Engine Oil

    Gasohol containing ethanol can be used if ethanol content does not exceed 10% and the fuel meets minimum octane ratings. Gasohol containing methanol is not rec- ommended by Yamaha because it can cause fuel system damage or engine perfor- mance problems. EJU01044...

  • Page 48: Filling The Fuel Tank

    EJU01045 Filling the fuel tank CAUTION: Be careful when refueling. Avoid getting water or other contaminants in the fuel tank. Contaminated fuel can cause poor running or engine damage. 1. Open the hood and remove the front storage compartment, to check the fuel level.

  • Page 49: Filling The Oil Tank

    If bleeding of the oil pump is necessary, have a Yamaha dealer bleed it. 1. Remove the seat to watch the oil level. (See page 2-5 for seat.) 2. Open the oil tank filler cap, and very slowly add engine oil to the oil tank.

  • Page 50: Pre-Operation Checks

    EJU01346 Pre-operation checks EJU01347 Pre-operation check list Before operating this watercraft, perform the checks in the following check list. See the accompanying text in this chapter for details on how to perform the checks. WARNING If any item in the pre-operation check list is not working properly, have it inspected and repaired before operating the watercraft, otherwise an accident could occur.

  • Page 51: Pre-Operation Check Points

    EJU01048 Pre-operation check points EJU01050 Engine compartment Ventilate the engine compartment before each use. To ventilate the engine compartment, remove seat and front storage compart- ment. (See page 2-5 for seat, and 2-18 for front storage compartment.) Allow the engine compartment to remain open for a few minutes to allow any fuel vapors to escape.

  • Page 52: Water Separator

    EJU01961 Water separator Check the water separator 1 for water. Normally the water separator is empty. The water separator retains any water entering through the fuel tank breather hose if the watercraft is capsized. If water remains in the water separator, drain it by removing the drain screw 2.
  • Page 53 EJU01969 Battery Check the battery condition and the elec- trolyte level. Check that the battery leads are tightened securely and there is no corrosion on the battery terminals. WARNING The battery must always be fully charged and in good condition. Loss of battery power may leave you stranded.

  • Page 54: Fire Extinguisher

    Always carry a fire extinguisher on board. A fire extinguisher is not standard equip- ment with this watercraft. If you do not have one, contact a Yamaha dealer or a fire extinguisher dealer to obtain one meeting the proper specifications.
  • Page 55 EJU01834 Throttle Squeeze and release the throttle lever several times to make sure that there is no hesitation in its travel. It should be smooth over the complete range, and spring back to the idle position when released. WARNING Before starting the engine, always check the operation of the throttle lever.

  • Page 56: Jet Unit

    EJU01058 Jet unit Carefully check the jet intake for weeds, debris, or anything else that might restrict the intake of water. If the intake is clogged, cavitation could occur, reducing jet thrust, and possibly damaging the jet pump. In some cases, the engine may overheat because of lack of cooling water, and dam- age to the engine could result.
  • Page 57 EJU01835 Switches Check the start switch 1, the engine stop switch 2, and the engine shut-off switch 3 for proper operation. To check these switches, place the water- craft in the water to provide adequate cooling. Start the engine, and then pull the engine shut-off cord 5 to remove the clip 4 from the engine shut-off switch.

  • Page 58: Operation

    Operation WARNING Before operating your watercraft, become familiar with all controls. Con- sult your Yamaha dealer about any con- trol function fully understand. Failure to understand how controls work could cause an accident or prevent you from avoiding an accident.
  • Page 59 1. Launch the watercraft and start the engine. (See page 3-15 for engine start- ing procedures.) 2. Run the engine at the lowest possible speed for 5 minutes. 3. Gradually open the throttle to 3/4 or less. 4. Continue operation at 3/4 throttle or less until the first tankful of fuel has been used.

  • Page 60: Starting The Engine

    EJU01065 Starting the engine WARNING Never start the engine or let it run for any length of time in an enclosed area. Exhaust fumes contain carbon monox- ide, a colorless, odorless gas that may cause loss of consciousness and death within a short time.
  • Page 61 2. Turn the fuel cock knob to the “ON” posi- tion. NOTE: Before starting the watercraft, after it has been sitting, remove the fuel tank filler cap to release any built-up pressure in the tank due to fuel expansion. 3. Attach the clip 1 to the engine shut-off switch 2.
  • Page 62 5. While lightly squeezing the throttle lever, push the start switch (green button). WARNING On this watercraft, the engine is con- nected directly to the jet pump. Starting the engine immediately generates some thrust. Apply only enough throttle to keep the engine running. 6.

  • Page 63: Stopping The Engine

    EJU01066 Stopping the engine To stop the engine, release the throttle lever, and then push the engine stop switch (red button). WARNING You need throttle to steer.

    EJU01073 Starting and boarding in shallow water 1. Do not start the engine in less than 60 cm (2 ft) of water. Put the watercraft in water that is deep enough, and then board the watercraft from the side or the rear.

  • Page 68: Boarding And Starting In Deep Water

    EJU01075 Boarding and starting in deep water WARNING Operator and passenger should prac- tice getting on board in shallow water before riding in deep water. Boarding in deep water requires more skill. The fatigue and exposure that could F0X0316 result after unsuccessful attempts to get back on the watercraft may increase the risk of injuries and drown- ing.

  • Page 69: Boarding With A Passenger

    EJU01077 Boarding with a passenger WARNING Severe internal injuries can occur if water is forced into body cavities as a result of being near the jet thrust nozzle. Do not apply throttle until the passenger is seated with his or her feet on the floor of the footwell and is holding on to the F0X0319 operator.

  • Page 70: Capsized Watercraft

    NOTE: The heavier the total weight of the operator and passengers, the more difficult it will be to balance the watercraft. Do not operate the watercraft when the total weight exceeds 160 kg (353 lb) including any cargo. If it is difficult to balance the watercraft at a stand- still, proceed as follows: 1.
  • Page 71 CAUTION: Be sure to remove the clip from the engine shut-off switch, otherwise the engine will overheat and engine damage may occur. 1. Shut the engine off by removing the clip from the engine shut-off switch. 2. Swim to the rear of the watercraft. Pull the watercraft over with left hand on ride plate while pushing down on the gun- wale with your right hand/foot.

  • Page 72: Turning The Watercraft

    EJU01839 Turning the watercraft Steering control depends on the combi- nation 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.
  • Page 73 WARNING Do not release the throttle when trying to steer away from objects—you 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 turning. Sharp high-speed turns may cause the watercraft to slide side- ways or spin, throwing the operator passengers...
