GEN INFO General information 1-3 68F1F11 Safety while working 1 To prevent an accident or injury and to ensure quality service, follow the safety pro- cedures 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 ade- quate ventilation can be maintained. Self-protection Protect your eyes by wearing safety glasses or safety goggles during all operations involv- ing drilling and grinding, or when using an air compressor. Protect your hands and feet by wearing pro- tective gloves and safety shoes when neces- sary. Parts, lubricants, and sealants Use only genuine Yamaha parts, lubricants, and sealants or those recommended by Yamaha, when servicing or repairing the out- board motor. Under normal conditions, the lubricants men- tioned 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 outboard motor.
68F1F11 1-4 1 2 3 4 5 6 7 8 9 6. Keep a supply of clean, lint-free cloths for wiping up spills, etc. Good working practices Special service tools Use the recommended special service tools to protect parts from damage. Use the right tool in the right manner—do not improvise. Tightening torques Follow the tightening torque specifications provided throughout the manual. When tight- ening nuts, bolts, and screws, tighten the large sizes first, and tighten fasteners starting in the center and moving outward. Non-reusable parts 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 engine oil to the contact surfaces of moving parts before assembly. 3. Install bearings with the manufacture identification mark in the direction indi- cated in the installation procedure. In addition, be sure to lubricate the bearings liberally. 4. Apply a thin coat of water-resistant grease to the lip and periphery of an oil seal before installation. 5. Check that moving parts operate nor- mally after assembly. Safety while working
GEN INFO General information 1-5 68F1F11 Identification 1 Applicable models This manual covers the following models. Serial number The outboard motor serial number is stamped on a label attached to the port clamp bracket. 1 Model name 2 Approved model code 3 Transom height 4 Serial number Propeller selection 1 The performance of a boat and outboard motor will be critically affected by the size and type of propeller you choose. Propellers greatly affect boat speed, acceleration, engine life, fuel economy, and even boating and steering capabilities. An incorrect choice could adversely affect performance and could also seriously damage the engine. Use the following information as a guide for selecting a propeller that meets the operating conditions of the boat and the outboard motor. Propeller size The size of the propeller is indicated on the propeller boss end and on the side of the pro- peller boss. a Propeller diameter (in inches) b Propeller pitch (in inches) c Propeller type (propeller mark) Applicable models Z150TR, LZ150TR, VZ150TR, Z175TR, VZ175TR, Z200TR, LZ200TR, VZ200TR Model name Approved model code Starting serial No. Z150TR 6G4 1006970– LZ150TR 6K0 1000468– VZ150TR 6J9 1003950– Z175TR 6G5 1000348– VZ175TR 62H 1000310– Z200TR 6G6 1008788– LZ200TR 6K1 1001418– VZ200TR 60F 1001055– S69J1100 × - a b c S60C1125 - bc
68F1F11 1-6 1 2 3 4 5 6 7 8 9 Selection When the engine speed is at the full throttle operating range (4,500–5,500 r/min), the ideal propeller for the boat is one that pro- vides maximum performance in relation to boat speed and fuel consumption.
