  • Page 32: Installation

    EMU00175 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.

  • Page 33: Mounting The Outboard Motor

    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.

  • Page 34 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 35: Clamping The Outboard Motor

    EMU00183 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 the motor as they can work loose due 409011 to engine vibration.

  • Page 36: Filling Fuel

    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.

  • Page 37: Pre-Operation Checks

    EMU00204 PRE-OPERATION CHECKS If any item in the pre-operation check is not working properly, have it inspected and repaired before operating the out- board motor. Otherwise, an accident could occur. Do not start the engine out of water. Overheating and serious engine damage can occur.
  • Page 38 EMU00209 Controls 8 Check throttle, shift, and steering for proper operation before starting the engine. 8 The controls should work smoothly, without binding or unusual free play. 8 Look for loose or damaged connec- tions. 8 Check operation of the starter and stop switches when the outboard motor is in the water.

  • Page 39: Checking The Engine Oil Level

    EMU01434 CHECKING THE ENGINE OIL LEVEL 1) Put the outboard motor in an upright position (not tilted). 2) Loosen and remove the oil dipstick and wipe it clean. 3) Completely screw in the dipstick and remove it again. 4) Check the oil level using the dipstick to be sure the level falls between the upper and lower marks.

  • Page 41: Starting Engine

    EMU00968 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 902013 water near you. 8 When the air-vent screw is loosened, gasoline(petrol) vapor will be released.
  • Page 42 EMU14970 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. 5) Attach the engine stop switch lanyard to a secure place on your clothing, or your arm or leg.
  • Page 43 EMU01366 Manual Start Model 7) Pull out the choke knob completely. NOTE: It is not necessary to use the choke when restarting a warm engine. 8) Pull the starter handle slowly until you feel resistance. Then give a strong pull straight out to crank and start the engine.

  • Page 46: Stopping Engine

    EMU00273 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. EMU00969 1) Push and hold the engine stop button until the engine comes to a complete stop.

  • Page 47: 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 48: 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 the motor up slightly.
  • Page 49 EMU19160 Trim angle settings and boat handling When the boat is on plane, a bow-up atti- tude results in less drag, greater stability and efficiency. This is generally when the keel line of the boat is up about 3 to 5 degrees.

  • Page 50: Tilting Up/Down

    NOTE: Depending on the type of boat, the out- board motor trim angle may have little effect on the trim of the boat when oper- ating. EMU00284 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...
  • Page 51 Leaking fuel is a fire hazard. Tighten the air-vent screw and place the fuel cock in the closed position if the engine will be tilted for more than a few minutes. Oth- erwise, fuel may leak. EMU01372 PROCEDURE FOR TILTING UP 1) Tighten the air vent screw(s).
  • Page 52 5) Hold the rear handle and tilt the engine up fully until the tilt support bar automatically turns to the locked position. EMU01371 PROCEDURE FOR TILTING DOWN 1) Slightly tilt up the engine. 2) Tilt down the engine while pulling the tilt support bar lever up.

  • Page 53: Cruising In Shallow Water

    EMU01370 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- 000813 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 54: Cruising In Other Conditions

    EMU00308 PROCEDURE 1) Slightly tilt up the engine and the tilt- support 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.

The oil is hot and should be handled with care to avoid burns. 8 Be sure the outboard is securely fas- tened to the transom or a stable stand. 8 Change the engine oil after the first 10 hours of operation, and every 100 hours or at 6-month intervals thereafter.
  • Page 70 NOTE: 8 For disposal of used oil consult your Yamaha dealer. 8 The oil should be changed more often when the engine is operated under adverse conditions such as extended trolling.

  • Page 74: Changing Gear Oil

    Inspect the used oil after it has been drained. If the oil is milky, water is get- ting into the gear-case which can cause gear damage. Consult a Yamaha dealer for repair of the lower unit seals. NOTE: For disposal of used oil consult your Yamaha dealer.

  • Page 75: Cleaning Fuel Tank

    Gasoline (petrol) is highly flammable, and its vapors are flammable and explosive. 8 If you have any question about properly doing this procedure, consult your Yamaha dealer. 8 Keep away from sparks, cigarettes, flames or other sources of ignition when cleaning the fuel tank.

  • Page 76: Inspecting And Replacing Anode(S)

    Yamaha outboard motors are protected from corrosion by sacrificial anodes. Inspect the external anodes periodically. Remove scales from the surfaces of the anodes. Consult a Yamaha dealer for replacement of external anodes. Do not paint anodes, as this would ren- der them ineffective.

  • Page 77: Checking Bolts And Nuts

    Check the motor for scratches, nicks, or flaking paint. Areas with damaged paint are more likely to corrode. If necessary, clean and paint the areas. A touch-up paint is available from a Yamaha dealer. EMU00413 COATING THE BOAT BOTTOM A clean hull improves boat performance.
