NOTICE This manual has been prepared by Yamaha primarily for use by Yamaha dealers and their trained mechanics when performing maintenance procedures and repairs to Yamaha equipment. It has been written to suit the needs of persons who have the Bronze Technical Certificate of YTA (Yamaha Technical Academy) marine or the same basic understanding of the mechanical and electrical con- cepts and procedures inherent in the work, for without such knowledge attempted repairs or service to the equipment could render it unsafe or unfit for use. Because Yamaha has a policy of continuously improving its products, models may differ in detail from the descriptions and illustrations given in this publication. Use only the latest edition of this manual. Authorized Yamaha dealers are notified periodically of modifications and significant changes in specifications and procedures, and these are incorporated in successive editions of this manual. Important information Particularly important information is distinguished in this manual by the following notations: The Safety Alert Symbol means ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED! WARNING Failure to follow WARNING instructions could result in severe injury or death to the machine operator, a bystander, or a person inspecting or repairing the outboard motor. CAUTION: A CAUTION indicates special precautions that must be taken to avoid damage to the outboard motor. NOTE: A NOTE provides key information to make procedures easier or clearer.

0-2 6X61K12 BASIC INFO Basic information Safety while working To prevent an accident or injury and to ensure quality service, follow the safety procedures provided below. Handling of gasoline • Gasoline is highly flammable. Keep gasoline and all flammable products away from heat, sparks, and open flames. • Gasoline must be handled with great care. Wash it off with water immediately if your skin or outfit is tainted with gasoline. • If gasoline should get into someone’s eye, wash it off immediately with clean water and see a doctor. • If someone should erroneously swallowed gasoline, see a doctor urgently. Gasoline may cause serious effect on a human body. 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 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. Part, lubricant, and sealant Use only genuine Yamaha parts, lubricants, and sealants or those recommended by Yamaha, when servicing or repairing the outboard motor. Handling of sealant • Wear protective gloves to protect your skin, when using the sealants. • Refer to the material data sheet issued by the manufacturer. Some of the sealants may be harmful for human health. y0006000i y0006001i y0006002i y0006003i y0006004i

6X61K12 0-3 Safety while working 0 2 3 4 5 6 7 8 9 Special service tool Use the recommended special service tools to protect parts from damage. Use the right tool in the right manner—do not improvise. 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. Non-reusable part Always use new gaskets, seals, O-rings, cot- ter pins, circlips, etc., when installing or assembling parts. Disassembly and assembly 1. Use compressed air to remove dust and dirt during disassembly. 2. Apply specified grease to the contact sur- faces of moving parts before assembly. 3. Apply a thin coat of water-resistant grease to the lip and periphery of an oil seal before installation. 4. Check that moving parts operate nor- mally after assembly. Working with crane • Outboard motors weighing 18.0 kg (39.7 lb) and over must be carried by a crane. • Use a wire rope of adequate strength, and lift up the outboard motor with the three point suspension. • If the outboard motor does not have three or more points to be suspended, support it with additional ropes or the like so that the outboard motor can be lifted and carried in a stable manner. y0006005i y0006006i S6X600042 y0006008i

0-4 6X61K12 BASIC INFO Basic 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 figure below for an example page). • The component list consists of part names and quantities, as well as bolt and screw dimensions (see b in the figure below). • Symbols are used to indicate important aspects of a procedure, such as the grade of lubricant and lubrication point (see c in the figure below). • Tightening torque specifications are provided in the exploded diagrams (see d in the figure below for an example), 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 figure below for an example page). NOTE: For troubleshooting procedures, see Chapter 2, “Troubleshooting.” 5-14 Digital Electronic Control disassembly 1 1 3 4 5 5 7 8 9 Assembling the Digital Electronic Control ECM housing 1. Install the Digital Electronic Control ECM b in the housing a. CAUTION: Do not make impact on the Digital Elec- tronic Control ECM in the course of installation. Digital Electronic Control ECM is precision equipment that requires careful handling. 2. Put the PTT switch wiring c into the groove on the rear housing d. 3. Install the stopper plate e (STBD side). 4. Put the neutral switch wiring f and the free throttle switch wiring g through the point a, and put the PTT switch wiring h through the point b on the opposite side. Install the stopper plate i (PORT side) paying attention not to pinch the wirings by the stopper plate i. 5. Install the control lever, and check that the PTT switch wiring f will not be strained while the control lever is moved over the full stroke. a b S6X605023 e c d S6X605024 a b i h h g S6X605025 f S6X605027 5-7 OVER HAUL Overhaul Gear housing No. Part name Q’ty Remarks 1 Digital Electronic Control case assembly 1 2 Neutral switch assembly 1 3 Lock plate 1 4 Screw 2 ø3 x 10mm 5 Screw 4 ø5 x 14mm 6 Rear housing 1 7 Gear 4 8 Screw 2 ø5 x 10mm 9 Drive a rm 1 10 Drive shaft 1 11 Friction plate 1 12 Detent spring 1 13 Detent adapter 1 14 Detent roller 1 15 Spring 1 16 Washer 1 17 Bolt 1 1 2 3 4 4 5 5 6 7 8 8 9 10 11 12 13 14 15 16 17 18 20 19 3.0 N m (0.3 kgf m, 2.2 ft lb) 0.4 N m (0.04 kgf m, 0.3 ft lb) S6X605002-3 a c d b e
