1-1 GEN INFO General information Safety while working To prevent an accident or injury and to pro- vide quality service, observe the following safety procedures. Rotating part • Hands, feet, hair, jewelry, clothing, personal flotation device straps, and so on, can become entangled with internal rotating parts of the engine or jet pump unit, resulting in serious injury or death. • Keep hands, feet, hair, jewelry, clothing, personal flotation device straps, and so on, away from any exposed moving parts when operating the engine with the seat removed. • Keep away from intake grate while engine is on. Items such as hair, clothing, or personal flotation device straps can become entangled in moving parts resulting in severe injury. Hot part During and after operation, engine parts are hot enough to cause burns. Do not touch any parts in the engine compartment until the engine has cooled. Electric shock Do not touch any electrical parts while starting or operating the engine. Otherwise, shock or electrocution could result. Impeller Do not hold the impeller with your hands when loosening or tightening the impeller. Handling of gasoline • Gasoline is highly flammable. Keep gasoline and all flammable products away from heat, sparks, and open flames. • Gasoline is poisonous and can cause injury or death. Handle gasoline with care. Never siphon gasoline by mouth. If you swallow some gasoline, inhale a lot of gasoline vapor, or get some gasoline in your eyes, see your doctor immediately. If gasoline spills on your skin, wash with soap and water. If gasoline spills on your clothing, change your clothes.

1-2 Safety while working 1 2 3 4 5 6 7 8 9 A Ventilation • Gasoline vapor and exhaust gas are heavier than air and extremely poisonous. If gasoline vapor or exhaust gas is inhaled in large quantities, it may cause loss of con- sciousness and death within a short time. • When test running an engine indoors (for example, in a water tank) make sure to do so where adequate ventilation can be main- tained. Self-protection • Protect your eyes by wearing safety glasses or safety goggles during all opera- tions involving drilling and grinding, or when using an air compressor. • Protect your hands and feet by wearing protective gloves and safety shoes when necessary. Working with crane • When moving the watercraft, or when lifting the engine during removal or installation, make sure to use a crane with a lifting capacity that is equal to or more than the weight of the watercraft or engine respec- tively. • When lifting the watercraft, use the watercraft lift harness and make sure that the watercraft is in a stable position when moving it. • Use the wire ropes of adequate strength, and lift up the engine unit using the three point suspension. • If the engine unit does not have three or more points to be suspended, support it using additional ropes or the like so that the engine unit can be lifted and carried in a stable manner.

1-3 GEN INFO General information Handling of heat gun • Improper handling of a heat gun may result in burns. For information on the proper handling of the heat gun, see the operation manual issued by the manufacturer. • When using a heat gun, keep it away from the gasoline and oil, to prevent a fire. • Components become hot enough to cause burns. Do not touch any hot components directly. Part, lubricant, and sealant Use only genuine Yamaha parts, lubricants, and sealants, or those recommended by Yamaha, when servicing or repairing the watercraft. Handling of sealant • Wear protective gloves to protect your skin, when using the sealants. • See the material safety data sheet issued by the manufacturer. Some of the sealants may be harmful to human health. Special service tool Use the recommended special service tools to work safely, and to protect parts from dam- age. Tightening torque Follow the tightening torque specifications provided throughout the manual. When tightening nuts, bolts, and screws, tighten the large sizes first, and tighten fasteners starting in the center and moving outward.

1-4 Safety while working 1 2 3 4 5 6 7 8 9 A Non-reusable part Always use new gaskets, seals, O-rings, cot- ter pins, and so on, when installing or assem- bling parts. Disassembly and assembly • Use compressed air to remove dust and dirt during disassembly. • Apply engine oil to the contact surfaces of moving parts before assembly. • Install bearings so that the bearing identification mark is facing in the direction indi- cated in the installation procedure. In addition, make sure to lubricate the bearings liberally. • Apply a thin coat of water resistant grease to the lip and periphery of an oil seal before installation. • Check that moving parts operate normally after assembly.

1-5 GEN INFO General information How to use this manual Manual format The format of this manual has been designed to make service procedures clear and easy to under- stand. Use the information below as a guide for effective and quality service. • Parts are shown and detailed in an exploded diagram and are listed in the component list (see a in the following figure for an example page). • The component list consists of part names and quantities, as well as bolt and screw dimensions (see b in the following figure). • Symbols are used to indicate important aspects of a procedure, such as the grade of lubricant and the lubrication point (see c in the following figure). • Tightening torque specifications are provided in the exploded diagrams (see d in the following figure), and in the related detailed instructions. Some torque specifications are listed in stages as torque figures or angles in degrees. • Separate procedures and illustrations are used to explain the details of removal, checking, and installation where necessary (see e in the following figure for an example page). TIP: For troubleshooting procedures, see Chapter 9, “Troubleshooting.”
