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. 3-27 E EMU00317 Chapter 4 MAINTENANCE 1 2 3 4 5 6 SPECIFICATIONS . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-1 TRANSPORTING AND STORING OUTBOARD MOTOR . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-4 Trailering outboard motor . . . . . . . . . . . . . . . . . . . 4-4 Storing outboard motor . . . . . . . . . . . . . . . . . . . . . . . 4-5 PERIODIC MAINTENANCE. . . . . . . . . . . . . . . . . . . . 4-10 Replacement parts . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-10 Maintenance chart . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-11 Greasing. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-12 Cleaning and adjusting spark plug . . . 4-14 Checking fuel system . . . . . . . . . . . . . . . . . . . . . . . . . 4-16 Inspecting fuel filter . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-17 Adjusting idling speed . . . . . . . . . . . . . . . . . . . . . . . 4-18 Changing engine oil. . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-19 Checking timing belt. . . . . . . . . . . . . . . . . . . . . . . . . . . 4-21 Replacing fuse. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-22 Checking wiring and connectors. . . . . . . 4-22 Exhaust leakage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-22 Water leakage. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-22 Checking power trim and tilt system . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-23 Checking propeller. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-24 Changing gear oil. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-26 Cleaning fuel tank . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-28 Inspecting and replacing anode(s). . . . 4-29 Checking battery . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-30 Checking bolts and nuts. . . . . . . . . . . . . . . . . . . . . 4-32 Cleaning cooling-water passages . . . . . 4-33 Motor exterior . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-34 Coating the boat bottom . . . . . . . . . . . . . . . . . . . . 4-34 E EMU00322* SPECIFICATIONS 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 Valve clearance (cold engine) IN EX Battery Min. reserve capacity (RC/SAE) Alternator output Starting carburetion system DRIVE UNIT Gear positions Gear ratio Trim and tilt system Propeller mark FUEL AND OIL Recommended fuel Fuel tank capacity Recommended engine oil P.

When transporting and storing the outboard motor, close the air vent screw and fuel cock to prevent fuel from leaking. EMU00326 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. 001213 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. Install the silencer cover and top cowling. q w 7) 1 Water surface 2 Lowest water level 605024 EMU00342 q 8 Flushing with the Flushing Attachment cC Avoid running the outboard at high speed while on the flushing attachment, or overheating could occur. Remove the top cowling and the propeller. 2) Install a flushing attachment 1 to the cooling water inlet. 3) Run the engine at a fast idle for 10~15 minutes supplying fresh water. 4) Just prior to turning off the engine, quickly spray "Yamaha Stor-Rite Engine Fogging Oil" (Part No. LUBSTRRT-12-00) alternately into the silencer cover. When properly done, the engine will smoke excessively and almost stall. 5) Remove the flushing attachment and wipe off any excess water. 6) Install the top cowling and the propeller. NOTE: A flushing attachment is available from a Yamaha dealer. 1) 605014* 4-7 E EMU00349 Lubrication 1) Remove the spark plug(s).
