    EMF10010 INSTALLATION Incorrect engine height or obstructions to smooth water flow (such as the design or condition of the boat or accessories such as transom ladders/depth finder trans- ducers) can create airborne water spray while the boat is cruising. Severe engine damage may result if the motor is operat- ed continuously in the presence of air- borne water spray.

    EMU00176 MOUNTING THE OUTBOARD MOTOR Improper mounting of the outboard motor could result in hazardous condi- tions such as poor handling, loss of con- trol, or fire hazards. Observe the follow- ing: 8 The information presented in this sec- tion is intended as reference only. It is possible provide complete...

  • Page 32

    Overpowering a boat may cause severe instability. Do not install an outboard motor with more horsepower than the maximum rating on the capacity plate of the boat. If the boat does not have a capacity plate, consult the boat manufac- turer.

  • Page 33: Clamping The Outboard Motor

    EMF14010 CLAMPING THE OUTBOARD MOTOR 1) Place the outboard on the transom so that it is positioned as close to the center as possible. Tighten the tran- som clamp screws evenly and secure- ly. Check the clamp-screws for tight- ness occasionally during operation of 409011 the motor as they can work loose due to engine vibration.

  • Page 34: Filling Fuel And Engine Oil

    While many additives available may reduce deposits, Yamaha recommends the use of Ring Free Fuel Additive, avail- able from your Yamaha dealer. Ring Free has repeatedly proven its ability to clean combustion deposits from inside the engine, notably the critical piston-ring- land area, and fuel system components.

    Break-in (running-in) time:10 hours Break-in (running-in) premix ratio: Refer to “Gasoline/Petrol and Oil Mixing”. EMU00226 Run the engine under load (in gear with a propeller installed) as follows. 1) First 10 minutes: Run the engine at the lowest possi- ble-speed. A fast idle in neutral is best.

  • Page 39: Starting Engine

    EMU01147 STARTING ENGINE 8 Before starting the engine, make sure that the boat is tightly moored and that you can steer clear of any obstructions. Be sure there are no swimmers in the 902053 water near you. 8 When the air vent screw is loosened, gasoline (petrol) vapor will be released.

  • Page 40

    EMU00854 PROCEDURE FOR TILLER CONTROL MODEL 4) Place the gear-shift lever in the neu- tral position. NOTE: The start-in-gear protection device pre- vents the engine from starting except when in Neutral. 406042 5) Place the throttle control grip in the “START”...

    EMU00241* Manual Start Model 7) Pull out the choke knob completely when the engine is cold. After the engine starts, set the choke knob to the 2nd or 3rd position for warming up the cold engine. After warming up the engine, set the choke knob to the original position.

  • Page 42: Warming Up Engine

    EMG00010-* WARMING UP ENGINE 1) Before beginning operation, allow the engine to warm up at idling speed for 3 minutes. (Failure to do this will shorten engine life.) 2) Check for a steady flow of water from the cooling-water pilot hole. 309012 A continuous flow of water from the pilot hole shows that the water pump is...

    EMG20111 SHIFTING Before shifting, make sure there are no swimmers or obstacles in the water near you. To change the shifting position from for- ward to reverse or vice-versa, close the throttle first so that the engine idles (or runs at low speeds). EMG22110 FORWARD 1) Place the throttle control grip in the...

  • Page 44: Reverse

    EMG33210 REVERSE When operating in Reverse, go slowly. Do not open the throttle more than half. Oth- erwise, the boat may become unstable, which could result in loss of control and an accident. 503012 1) Place the throttle control grip in the fully closed position (for Tiller control model).

  • Page 45: Stopping Engine

    EMG38010 STOPPING ENGINE Let it cool off for a few minutes at idle or low speed first. Stopping the engine immediately after operating at high speed is not recommended. EMU00275 1) Push and hold the engine stop button 407021* until the engine comes to a complete stop.

  • Page 46: Trimming Outboard Motor

    EMU01412 TRIMMING OUTBOARD MOTOR The trim angle of the outboard motor helps determine the position of the bow of the boat in the water. The correct trim angle will help improve performance and fuel economy while reducing strain on the engine.

  • Page 47: Adjusting Trim Angle

    ADJUSTING TRIM ANGLE EMU00951 Manual tilt model There are 4 or 5 holes provided in the clamp bracket to adjust the outboard motor trim angle. 1) Stop the engine. 2) Remove the trim angle adjusting rod 1 from the clamp bracket while tilting 404013* the motor up slightly.

  • Page 48

    EMG62010 Bow up When the boat is on plane, a bow-up atti- tude result in less drag, greater stability and efficiency. This is generally when the keel line of the boat is up about 3 to 5 degrees. When trimmed out, the boat may have more tendency to steer to one side or the other.

  • Page 49: Cruising In Shallow Water

    EMG70011 CRUISING IN SHALLOW WATER The outboard motor can be tilted up par- tially to allow operation in shallow water. 8 Place the gear shift in the Neutral posi- 000832 tion before using the shallow water cruising system. 8 Run the boat at the lowest possible speed when using the shallow water cruising system.

  • Page 50

    EMG71210 PROCEDURE 1) Place the gear shift lever in the neu- tral position. 406042 2) Pull up the tilt lock lever. 402015 3) Slightly tilt up the engine. The tilt- support bar will lock automatically, supporting the engine in a partially raised position.

  • Page 51: Tilting Up/down

    EMH10110 TILTING UP/DOWN If the engine will be stopped for some time, or if the boat is moored in shallows, the engine should be tilted up to protect the propeller and casing from damage by collision with obstructions, and also to reduce salt corrosion.

  • Page 52

    EMU00290 PROCEDURE FOR TILTING UP 1) Place the gear shift lever in Neutral. 2) Remove the fuel line connection from the motor. 304013 3) Place the tilt lock lever in the release position. 402015 4) Hold the rear of the top cowling with one hand and fully tilt the engine up.

  • Page 53: Cruising In Other Conditions

    EMH60010 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 clogged- up with salt deposits. NOTE: Refer to cooling system flushing instruc- tions in “TRANSPORTING AND STORING OUTBOARD MOTOR”.

    1. Be sure your new Yamaha is registered for warranty. Your boat dealer should do this at the time of sale. Make sure your dealer gives you a copy of the completed Yamaha regis- tration card for your records.

  • Page 91

    5. Your warranty applies specifically to repairs made in the country of purchase. If your U.S.-purchased Yamaha needs warranty service while in Canada, or your Canadian pur- chased Yamaha needs service while in the United States, Yamaha will assist the local dealer whenever possible. However, some products available in one country may not be sold or serviced in the other.

    Owner’s Manual. The owner of the outboard motor shall give notice to an authorized Yamaha marine dealer of any and all apparent defects within ten (10) days of discovery and make the motor available at that time for inspection and repairs at the dealer’s place of business.

  • Page 93

    TRANSFER OF WARRANTY. Transfer of the warranty from the original purchaser to any subsequent purchaser is possible by having the motor inspected by an authorized Yamaha outboard dealer and requesting the dealer to submit a change of registration to Yamaha Motor Corporation, U.S.A.

  • Page 94

    The federal government requires each manufacturer of a motor vehicle to maintain a complete, up-to-date list of all first purchasers against the possibility of a safety-related defect and recall. This list is complied from the purchase registrations sent to Yamaha Motor Corporation, U.S.A.

  • Page 95

    Yamaha outside the U.S.A. or Canada, please contact an autho- rized Yamaha dealer in your country.
