  • Page 43: Filling Fuel And Engine Oil

    EMU00186 FILLING FUEL AND ENGINE OIL EMU00188 FILLING FUEL 1) Put the outboard in the tilt-down posi- tion. Remove the fuel tank cap. 2) Use a funnel if the nozzle on the fuel can or pump is not small enough or 902055 long enough to fit into the mouth of the fuel tank.

  • Page 44: Filling 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.

  • Page 45: Pre-Operation Checks

    3) Slowly fill the engine oil into the engine oil tank. 4) After filling, replace the all caps securely. 1 Oil filler access cap 2 Oil tank filler cap 203016 EMF40110 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.

    3) Watch for oil flowing through the oil feed pipes. After any air in the oil lines has been expelled, YAMAHA PRECISION BLEND SYSTEM should supply oil normally. If no oil has begun flowing after 10 minutes of idling, consult your Yamaha dealer.

  • Page 47: Breaking In (Running In) Engine

    EMF50112 BREAKING IN (RUNNING IN) ENGINE Your new engine requires a period of break-in (running-in) to allow mating sur- faces of moving parts to wear-in evenly. Correct break-in (running-in) will help ensure proper performance and longer engine life. 8 Failure to follow the break-in (running- in) procedure may result in reduced engine life or even severe engine dam- age.
  • Page 48 5 minutes at a time. Let the engine cool between full-throttle runs. Vary engine speed occasionally. 5) After the first 10 hours: Operate the engine normally. Use straight gasoline (petrol) in the fuel tank; YAMAHA PRECISION BLEND SYSTEM provides proper lubrication for normal operation.

  • Page 55: 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 56: Adjusting Trim Angle

    ADJUSTING TRIM ANGLE EMU01401 Power Trim/Tilt Model 8 Be sure all people are clear of the out- board motor when adjusting the trim/tilt angle, also be careful not to pinch any body parts between the drive 701034 unit and clamp bracket. 8 Use caution when trying a trim position for the first time.
  • Page 57 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 58: Tilting Up/Down

    EMU01200 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 59 EMU00295 PROCEDURE FOR TILTING UP Power tilt / Power trim/tilt model 1) Remove the fuel-line connection from the motor. (If the connector is provid- ed on the motor.) 2) Push the power tilt / power trim/tilt switch “UP” until the outboard has tilted up completely.

  • Page 60: Cruising In Other Conditions

    Be sure to retract the trim rods complete- ly during mooring. This protects the rods from marine growths and corrosion which could damage the power trim/tilt mechanism.
