Instruments and indicators 45 EMU31622 Command link multifunction speedometers The speedometer unit shows the boat speed and has functions of fuel meter and system voltage display. The chosen display is se- lected by using the “ ” (set) and “ ” (mode) buttons as described in this section. In addition, the speedometer can show the desired unit of measurement such as km/h, mph, or knots. If the speed sensor is in- stalled, the unit can also show the trip dis- play. However, even if the speed sensor is not installed, the trip display can be shown by connecting an optional sensor to the unit. In addition, if optional sensors are connected to the unit, water surface temperature dis- play, depth display, and clock will also be available. For the optional sensors, consult your Yamaha dealer. After the main switch is first turned on, all the displays come on as a test. After a few sec- onds, the gauge will change to normal oper- ation. For more information, see the operation manual originally supplied with the meter. EMU31632 Command link multifunction fuel management meters The fuel management meter has the func- tions of fuel flow meter, total consumption display, fuel economy display, and remaining fuel display.

49 Installation EMU26902 Installation The information presented in this section is intended as reference only. It is not possible to provide complete instructions for every possible boat and motor combination. Proper mounting depends in part on experience and the specific boat and motor combination. WA R N I N G EWM01590 ●Overpowering a boat could cause se- vere instability. Do not install an out- board motor with more horsepower than the maximum rating on the capac- ity plate of the boat. If the boat does not have a capacity plate, consult the boat manufacturer. ●Improper mounting of the outboard mo- tor could result in hazardous condi- tions such as poor handling, loss of control, or fire hazards. For permanent- ly mounted models, your dealer or oth- er person experienced in proper rigging should mount the motor. EMU33470 Mounting the outboard motor The outboard motor should be mounted so that the boat is well balanced. Otherwise, the boat could be hard to steer. For single-en- gine boats, mount the outboard motor on the centerline (keel line) of the boat. EMU26933 Mounting height (boat bottom) The mounting height of your outboard motor affects its efficiency and reliability. If it is mounted too high, propeller ventilation may occur, which will reduce propulsion due to excessive propeller slip, and the water in- takes for the cooling system may not get ad- equate water supply, which can cause engine overheating. If the engine is mounted too low, water resistance (drag) will increase, thereby reducing engine efficiency and per- formance. Most commonly, outboard motor should be mounted so that the anti-cavitation plate is in alignment with the bottom of the boat. The optimum mounting height of the outboard motor is affected by the boat/motor combina- tion and the desired use. Test runs at differ- ent heights can help determine the optimum mounting height. Consult your Yamaha deal- er or boat manufacturer for further informa- tion on determining the proper mounting height. 1. Center line (keel line) ZMU017601 6C1-9-19.book 49 ページ ２０１０年２月１７日 水曜日 午後１時３８分
Installation 50 NOTICE ECM01634 ●Make sure that the idle hole is high enough to prevent water from entering the engine even if the boat is stationary with the maximum load. ●Incorrect engine height or obstructions to the smooth flow of water (such as the design or condition of the boat, or ac- cessories, such as transom ladders or depth finder transducers) can create airborne water spray while the boat is cruising. If the outboard motor is oper- ated continuously in the presence of airborne water spray, enough water could enter the engine through the air intake opening in the top cowling to cause severe engine damage. Remove the cause of the airborne water spray. ZMU01762 6C1-9-19.book 50 ページ ２０１０年２月１７日 水曜日 午後１時３８分
51 Operation EMU36381 First-time operation EMU36391 Fill engine oil The engine is shipped from the factory with- out engine oil. If your dealer did not fill the oil, you must fill it before starting the engine. NOTICE: Check that the engine is filled with oil before first-time operation to avoid severe engine damage. [ECM01781] The engine is shipped with the following sticker, which should be removed after en- gine oil is filled for the first time. For more in- formation on checking the engine oil level, see page 53. EMU30174 Breaking in engine Your new engine requires a period of break- in to allow mating surfaces of moving parts to wear in evenly. Correct break-in will help en- sure proper performance and longer engine life. NOTICE: Failure to follow the break-in procedure could result in reduced engine life or even severe engine damage. [ECM00801] EMU27085 Procedure for 4-stroke models Your new engine requires a period of 10 hours break-in to allow mating surfaces of moving parts to wear in evenly. TIP: Run the engine in the water, under load (in gear with a propeller installed) as follows.For 10 hours for breaking in engine avoid ex- tended idling, rough water and crowded ar- eas. 1. For the first hour of operation: Run the engine at varying speeds up to 2000 r/min or approximately half throttle. 2. For the second hour of operation: Increase engine speed as much as nec- essary to put the boat on plane (but avoid full-throttle operation), then back off on the throttle while keeping the boat at a planing speed. 3. Remaining 8 hours: Run the engine at any speed. However, avoid operating at full throttle for more than 5 minutes at a time. 4. After the first 10 hours: Operate the engine normally. EMU36400 Getting to know your boat Different boats handle differently. Operate cautiously while you learn how your boat handles under different conditions and with different trim angles (see page 64). EMU36413 Checks before starting engine WA R N I N G EWM01921 If any item in “Checks before starting en- gine” is not working properly, have it in- spected and repaired before operating the outboard motor. Otherwise, an acci- dent could occur. NOTICE ECM00120 Do not start the engine out of water. Over- heating and serious engine damage can occur. EMU36421 Fuel level Be sure you have plenty of fuel for your trip. ZMU01710 6C1-9-19.book 51 ページ ２０１０年２月１７日 水曜日 午後１時３８分
Operation 52 A good rule is to use 1/3 of your fuel to get to the destination, 1/3 to return, and to keep 1/3 as an emergency reserve. With the boat lev- el on a trailer or in the water, turn the key to “ ” (on) and check the fuel level. For fuel filling instructions, see page 55. EMU36571 Remove the top cowling For the following checks, remove the top cowling from the bottom cowling. To remove the top cowling, release the cowling lock le- ver and lift off the top cowling. EMU36442 Fuel system WA R N I N G EWM00060 Gasoline and its vapors are highly flam- mable and explosive. Keep away from sparks, cigarettes, flames, or other sourc- es of ignition. WA R N I N G EWM00910 Leaking fuel can result in fire or explo- sion. ●Check for fuel leakage regularly. ●If any fuel leakage is found, the fuel system must be repaired by a qualified mechanic. Improper repairs can make the outboard unsafe to operate. EMU36451 Check for fuel leaks ●Check for fuel leaks or gasoline fumes in the boat. ●Check for fuel leakage from the fuel sys- tem. ●Check the fuel tank and fuel lines for cracks, swellings, or other damages. EMU36471 Check the fuel filter Check that the fuel filter is clean and free of water. If enough water to raise the float ring is found in the fuel, or if a significant amount of debris is found, the fuel tank should be checked and cleaned by a Yamaha dealer. EMU36902 Controls Tiller handle models: ●Move the tiller handle fully to the left and right to make sure operation is smooth. ●Turn the throttle grip from the fully closed to the fully open position. Make sure that it ZMU06085 ZMU05474 ZMU07079 6C1-9-19.book 52 ページ ２０１０年２月１７日 水曜日 午後１時３８分
Operation 53 turns smoothly and that it completely re- turns to the fully closed position. ●Look for loose or damaged connections of the throttle and shift cables. Remote control models: ●Turn the steering wheel full-right and full- left. Make sure operation is smooth and unrestricted throughout the whole range with no binding or excessive free play. ●Operate the throttle levers several times to make sure there is no hesitation in their travel. Operation should be smooth over the complete range of motion, and each le- ver should return completely to the idle po- sition. ●Look for loose or damaged connections of the throttle and shift cables. EMU36483 Engine shut-off cord (lanyard) Inspect the engine shut-off cord and clip for damage, such as cuts, breaks, and wear. EMU37052 Engine oil 1. Put the outboard motor in an upright po- sition (not tilted). NOTICE: If the motor is not level, the oil level indicated on the dipstick may not be accurate. [ECM01790] 2. Remove oil dipstick and wipe it clean. 3. Insert the dipstick and remove it again. Be sure to completely insert the dipstick into the dipstick guide, otherwise the oil level measurement will be incorrect. 4.
