[. . . ] If you have any question about the operation or maintenance of your outboard motor, please consult a Yamaha dealer. In this Owner's Manual particularly important information is distinguished in the following ways. cC 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. * Yamaha continually seeks advancements in product design and quality. [. . . ] NOTE: Refer to cooling system flushing instructions in "TRANSPORTING AND STORING OUTBOARD MOTOR". CRUISING IN TURBID WATER It is strongly recommended that the optional chromium-plated water-pump kit be installed if the outboard is to be used in turbid (muddy) water conditions. 3-22 E ­ MEMO ­ E EMU00317 Chapter 4 MAINTENANCE 1 2 3 4 5 6 SPECIFICATION DATA. . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-1 TRANSPORTING AND STORING OUTBOARD MOTOR . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-4 Trailering outboard motor. . . . . . . . . . . . . . . . . . . 4-4 Storing outboard motor . . . . . . . . . . . . . . . . . . . . . . 4-5 PERIODIC MAINTENANCE. . . . . . . . . . . . . . . . . . . . . . 4-9 Replacement parts . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-9 Maintenance chart. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-10 Greasing . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-11 Cleaning and adjusting spark plug. . . 4-12 Checking fuel system. . . . . . . . . . . . . . . . . . . . . . . . . 4-14 Inspecting fuel filter . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-15 Adjusting idling speed. . . . . . . . . . . . . . . . . . . . . . . 4-16 Checking water in engine oil tank . . . . 4-17 Checking high pressure fuel pump drive belt. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-18 Replacing fuse . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-19 Checking wiring and connectors . . . . . . 4-19 Exhaust leakage. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-19 Water leakage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-19 Checking power trim and tilt system . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-20 Checking propeller . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-21 Changing gear oil . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-23 Inspecting and replacing anode(s) . . . 4-24 Checking battery. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-25 Checking bolts and nuts . . . . . . . . . . . . . . . . . . . . 4-28 Cleaning cooling-water passages. . . . . 4-29 Motor exterior. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-30 Coating the boat bottom . . . . . . . . . . . . . . . . . . . 4-30 E EMU00318* SPECIFICATION DATA Model Item DIMENSIONS Overall Length Overall Width Overall Height Transom height Weight PERFORMANCE Full throttle operating range Maximum output Idling speed (Neutral) ENGINE Type Displacement Bore × stroke Ignition system Spark plug Spark plug gap Control system Starting system Battery capacity Minimum cold crank performance Minimum reserve capacity Alternator output Starting carburetion system DRIVE UNIT Gear positions Gear ratio Trim/tilt system Propeller mark FUEL AND OIL Recommended fuel Fuel tank capacity Recommended engine oil Fuel/oil premix ratio Engine oil capacity (engine oil tank) (remote oil tank) Recommended gear oil Gear oil capacity TIGHTENING TORQUE Spark plug Propeller nut N·m(kgf·m, lb·ft) N·m(kgf·m, lb·ft) 25 (2. 5, 18) 55 (5. 5, 40) P.

When transporting and storing the outboard motor, close the air vent screw and fuel cock to prevent fuel from leaking. EMU00326* 000896 TRAILERING OUTBOARD MOTOR The motor should be trailered and stored in the normal running position. If there is insufficient road clearance in this position, then trailer the motor in the tilt position using a motor support device such as a transom saver bar. For further details, consult your Yamaha dealer. 102074 w 8 Never get under the lower unit while it is tilted, even if a motor support bar is used. Severe injury could occur if the outboard accidentally falls. 8 USE CARE when transporting fuel tank, whether in a boat or car. 8 DO NOT fill fuel container to maximum capacity. Gasoline will expand considerably as it warms up and can build up pressure in the fuel container. This can cause fuel leakage and a potential fire hazard. cC Do not use the tilt support lever/knob when trailering the boat. When properly done, the engine will smoke excessively and almost stall. Remove the flushing attachment and wipe off any excess water. Install the silencer cover and top cowling. Install the propeller. 3) 4) 5) 6) 4-6 E EMU00350* Lubrication 1) Remove the spark plug(s). Spray a "Yamaha Stor-Rite Engine Fogging Oil" into each cylinder for 5 seconds. Grease the spark plug threads and reinstall the spark plug(s) and torque to proper specification. (Refer to "CLEANING AND ADJUSTING SPARK PLUG". ) 2) Turn the engine over with the stop lanyard disconnected to work the fogging oil into the piston rings. This prevents the formation of condensation. For models with a remote tank, it may be necessary to manually override the control unit to completely fill the engine main tank. (Refer to "CHANGING GEAR OIL"). Inspect the oil for the presence of water which indicates a leaky seal. [. . . ] If a question or problem arises regarding warranty, first contact the owner of the dealership.
