SAFETY WHILE WORKING
E
SAFETY WHILE WORKING To prevent and accident or injury and to ensure quality service, follow the safety procedures provided below.
FIRE PREVENTION Gasoline is highly flammable. Keep gasoline and all flammable products away from heat, sparks, and open flames.
VENTILATION Gasoline vapor and exhaust gas are heavier than air and extremely poisonous. If inhaled in large quantities they may cause loss of consciousness and death within a short time. When test running an engine indoors (e.g., in a water tank), be sure to do so where adequate ventilation can be maintained.
SELF-PROTECTION Protect your eyes by wearing safety glasses or safety goggles during all operation involving drilling and grinding, or when using an air compressor. Protect your hands and feet by wearing protective gloves or safety shoes when necessary.
PARTS, LUBRICANTS, AND SEALANTS Use only genuine Yamaha parts, lubricants, and sealants or those recommended by Yamaha, when servicing or repairing the watercraft.

Under normal conditions, the lubricants mentioned in this manual should not harm or be hazardous to your skin. However, you should follow these precautions to minimize any risk when working with lubricants. 1. Maintain good standards of personal and industrial hygiene. 2. Change and wash clothing as soon as possible if soiled with lubricants. 3. Avoid contact with skin. Do not, for example, place a soiled rag in your pocket. 4. Wash hands and any other part of the body thoroughly with soap and hot water after contact with a lubricant or lubricant soiled clothing has been made. 5. To protect your skin, apply a protective cream to your hands before working on the watercraft. 6. Keep a supply of clean, lint-free cloths for wiping up spills, etc.
GOOD WORKING PRACTICES 1. The right tools Use the recommended special service tools to protect parts from damage. Use the right tool in the right manner—do not improvise. 2. Tightening torques 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.

CAUTION: • When checking the engine oil level on water, be careful of other watercraft, boats, swimmers, or obstacles. The water current or wind can cause the watercraft to move and lead to a collision. • When checking the engine oil level on land, supply water to the cooling water passages. • Make sure that engine has enough oil but do not overfill. If there is too little oil, the engine can be damaged. if there is too much oil, the air filter can become saturated with oil, permanently damaging the filter and reducing engine performance. Follow the checking procedure carefully. • Make sure that debris or water does not enter the oil tank filler hole. Debris or water in the engine oil can cause serious engine damage.

• Remove the filler cap again and check that the oil level is between the minimum level mark a and maximum level mark b on the dipstick. • If the engine oil is below the minimum level mark a, add sufficient oil of the recommended type to raise it to the correct level. • If the engine oil is above the maximum level mark b, extract sufficient oil using an oil changer to lower it to the correct level. NOTE: If the oil temperature is low, the reading on the dipstick will be low, and if the temperature is high, the reading on the dipstick will be high.
Engine oil change — using oil changer
WARNING Avoid changing the engine oil immediately after turning the engine off. The oil is hot and should be handled with care to avoid burns.
CAUTION: • Do not run the engine with too much or not enough oil in the oil tank. Oil could spray out or the engine could be damaged. • Do not run the engine for more than 15 seconds without supplying water, when checking the oil level on land. The engine could overheat. • Be sure to change the engine oil after the first 10 hours of operation, and every 100 hours thereafter or at the start of a new season, otherwise the engine will wear quickly. 1.

Digital tester NOTE: Throughout this chapter the part numbers of the specified digital testers have been omitted. Refer to the following part numbers. Digital multimeter: YU-34899-A Digital circuit tester: 90890-03174 NOTE: “ ” indicates a continuity of electricity; i.e., a closed circuit at the respective switch position.

Low resistance measurement NOTE: • When measuring a resistance of 10 Ω or less with the digital tester, the correct measurement cannot be obtained because of the tester’s internal resistance. • To obtain the correct value, subtract the internal resistance from the displayed measurement. • The internal resistance of the tester can be obtained by connecting both of its terminals. Correct value = Displayed measurement – Internal resistance
Peak voltage measurement NOTE: • When checking the condition of the ignition system it is vital to know the peak voltage. • Cranking speed is dependant on many factors (e.g., fouled or weak spark plugs, a weak battery). If one of these is defective, the peak voltage will be lower than specification. • If the peak voltage measurement is not within specification the engine will not operate properly. • A low peak voltage will also cause components to prematurely wear.

Peak voltage adapter NOTE: • Throughout this chapter the peak voltage adapter’s part number has been omitted. Refer to the following part number. • The peak voltage adapter should be used with the digital tester. Peak volt meter adapter: YU-39991 Peak voltage adapter B: 90890-03172
È
• When measuring the peak voltage, connect the peak voltage adapter to the digital circuit tester and switch the selector to the DC voltage mode. NOTE: • Make sure that the adapter leads are properly installed in the digital circuit tester. • Make sure that the positive pin (the “+” mark facing up as shown) on the adaptor is installed into the positive terminal of the tester. • The test harness is needed for the following tests.

È Voltage measurement É Peak voltage measurement
Test harness Checking steps: • Disconnect the coupler connections. • Connect the test harness between the couplers. • Connect the tester terminals to the terminals which are being checked. • Run the engine and observe the measurement. NOTE: If the lighting coil and pickup coil(s) are measured unloaded, disconnect the test harness on the output side coupler.

INTRODUCTION FEATURES The newly developed Yamaha Diagnostic System provides quicker detection and analysis of engine malfunctions for quicker troubleshooting procedures than traditional methods. By connecting your computer to the ECM (Electronic Control Module) of a watercraft using the communication cable, this software can be used to display sensor data and data stored in the ECM on a computer’s monitor. If this software is run on Microsoft Windows® 95, Windows 98, Windows Me, Windows 2000, or Windows XP the information can be displayed in colorful graphics. Also, the software can be operated using either a mouse or a keyboard. In addition, the data for the main functions (Diagnosis, Diagnosis record, Engine monitor, and Data logger) can be saved on a disk or printed out. Functions 1. Diagnosis: Each sensor’s status and each ECM diagnosis code or item are displayed. This enables you to find malfunctioning parts and controls quickly. 2. Diagnosis record: Sensors that had been activated and ECM diagnostic codes that have been recorded are displayed. This allows you to check the watercraft’s record of malfunctions. 3. Engine monitor: Each sensor’s status and the ECM data are displayed. This enables you to find malfunctioning parts quickly. 4. Stationary test: With the engine off, ignition, fuel injection, and the electric fuel pump are checked. These tests can be performed quickly. 5. Active test: With the engine running, each firing cylinder drops and the engine speed is checked for changes to determine if the cylinder is malfunctioning. These tests can be performed quickly. 6. Data logger: From the data stored in the ECM, at least two items of 78 seconds of recorded data are displayed on a graph. In addition, the operating time as compared to the engine speed and the total operating time are displayed. This allows you to check the operating status of the engine. 7. Some files: Lets you select and run other applications while continuing to run the diagnostic program.

This chart specifies tightening torques for standard fasteners with a standard ISO thread pitch. Tightening torque specifications for special components or assemblies are provided in applicable sections of this manual. To avoid warpage, tighten multi-fastener assemblies in a crisscross fashion and progressive stages until the specified tightening torque is reached. Unless otherwise specified, tightening torque specifications require clean, dry threads. Components should be at room temperature.
