[. . . ] In this Owner's Manual particularly important information is distinguished in the following ways. The Safety Alert Symbol means ATTENTION!YOUR SAFETY IS INVOLVED! 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. [. . . ] 8 Run the boat at the lowest possible speed when using the shallow water cruising system. The tilt-lock mechanism does not work while the shallow water cruising system is being used. Hitting an underwater obstacle could cause the engine to lift out of the water, resulting in loss of control. 8 Do not rotate the engine 180° and operate the boat in reverse. Place the gearshift in the Reverse position to operate the boat in reverse. 8 Use extra care when operating in reverse. Too much reverse thrust can cause the engine to lift out of the water, increasing the chance of accident and personal injury. 8 Return the engine to its normal position as soon as the boat is back in deeper water. cC Place the gear-shift in the Neutral position before using the shallow water cruising system. 3-22 E EMU00308 PROCEDURE 1) Slightly tilt up the engine and the tiltsupport bar is turned to the locked position automatically to support the engine. 2) When bringing the engine to the home position, slightly tilt up the engine and slowly tilt the engine down pulling up the lever of the tilt support bar. NOTE: The outboard motor is provided 2 or 3 positions for shallow water cruising. EMU00316 CRUISING IN OTHER CONDITIONS CRUISING IN SALT WATER After operating in salt water, wash out the cooling-water passages with fresh water to prevent them from becoming cloggedup with salt deposits. 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. 3-23 E EMU00317 Chapter 4 MAINTENANCE 1 2 3 4 5 6 SPECIFICATION DATA. . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-1 TRANSPORTING AND STORING OUTBOARD MOTOR . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-2 Trailering outboard motor . . . . . . . . . . . . . . . . . . . 4-2 Transporting outboard when unmounted . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-3 Storing outboard motor . . . . . . . . . . . . . . . . . . . . . . . 4-3 PERIODIC MAINTENANCE. . . . . . . . . . . . . . . . . . . . . . 4-7 Replacement parts . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-7 Maintenance chart . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-8 Greasing. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-9 Cleaning and adjusting spark plug . . . 4-10 Checking fuel system . . . . . . . . . . . . . . . . . . . . . . . . . 4-11 Inspecting fuel filter . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-12 Adjusting idling speed . . . . . . . . . . . . . . . . . . . . . . . 4-13 Changing engine oil. . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-14 Checking wiring and connectors. . . . . . . 4-16 Exhaust leakage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-16 Water leakage. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-16 Checking propeller. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-17 Changing gear oil. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-19 Cleaning fuel tank . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-20 Inspecting and replacing anode(s). . . . 4-21 Checking bolts and nuts. . . . . . . . . . . . . . . . . . . . . 4-22 Motor exterior . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4-22 Coating the boat bottom . . . . . . . . . . . . . . . . . . . . 4-22 E EMU00322* 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 Valve clearance (cold engine) IN EX 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 P.
