Severe engine damage may result if the motor is operat- ed continuously in the presence of air- borne water spray.

  • Page 43: Mounting The Outboard Motor

    EMU01478 MOUNTING THE OUTBOARD MOTOR 8 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 manu- facturer.

    2) Watch for oil flowing through the oil feed pipes. After any air in the oil lines has been expelled, the Yamaha 212023 oil injection system should supply oil normally. If no oil has begun flowing after 10 minutes of idling, consult your Yamaha dealer.

  • Page 49: 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.

  • Page 57: 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 58: 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 trim/tilt angle, also be careful not to pinch any body parts between the drive unit and clamp bracket. 8 Use caution when trying a trim position for the first time.
  • Page 59 EMU01558 Bow Up 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. When trimmed out, the boat may have more tendency to steer to one side or the other.

  • Page 60: 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 61 EMU01548 PROCEDURE FOR TILTING UP Power trim/tilt models 1) If there is a fuel joint or a fuel cock on the boat, disconnect the fuel line or close the fuel cock. 2) Push the power trim/tilt switch “UP” until the outboard has tilted up com- pletely.
