    If engine speed is too high or too low for good engine performance, this will have an adverse effect on the engine. Yamaha outboard motors are fitted with propellers chosen to perform well over a range of applications, but there may be uses where a propeller with a different pitch would be more appropriate.

Severe engine damage may result if the motor is operated continuously in the presence of airborne water spray.

  • Page 41: Mounting The Outboard Motor

    EMU01478 MOUNTING THE OUTBOARD MOTOR 8 Overpowering boat 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 manufacturer.
  • Page 42 Mount the outboard motor on the center line (keel line) of the boat, and ensure that the boat itself is well balanced. Otherwise, the boat will be hard to steer. For boats without a keel or which are asymmetrical, consult your dealer.

  • Page 44: Breaking In (Running In) Engine

    EMU01534 BREAKING IN (RUNNING IN) ENGINE Your new engine requires a period of break- in (running-in) to allow mating surfaces of moving parts to wear-in evenly. Correct break-in (running-in) will help ensure proper performance and longer engine life. Failure to follow the break-in (running-in) procedure may result in reduced engine life or even severe engine damage.
  • Page 45 3) Second hour: Accelerate at full throttle onto plane, then reduce engine speed to three- quarter throttle (approximately 4,000 r/min). Vary engine speed occasionally. Run at full throttle for one minute, then allow about 10 minutes of operation at three-quarter throttle or less to let the engine cool.

  • Page 46: 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 62: 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 econo- my while reducing strain on the engine. The correct trim angle depends upon the combi- nation of boat, engine, and propeller.

  • Page 63: 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 001325 motor up slightly.
  • Page 64 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 posi- tion for the first time.
  • Page 65 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 66: Tilting Up/Down

    EMU00285 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 colli- sion with obstructions, and also to reduce salt corrosion.
  • Page 67 EMU00286 PROCEDURE FOR TILTING UP Manual tilt model 1) Remove the fuel-line connection from the motor. (If the fuel connector is pro- vided on the motor.) 001312 2) Place the tilt-lock lever in Release. 001313 3) Hold the rear of the top cowling with one hand, tilt the engine up, and turn the tilt-support lever to the locked posi- tion and support the engine.
  • Page 68 EMU01575 PROCEDURE FOR TILTING UP Power trim and tilt models 1) Disconnect the fuel line or close the fuel cock. 001312 2) Push the power trim and tilt switch “UP” until the outboard has tilted up com- pletely. 701034 000921 3) Turn the tilt support lever toward you to support the engine.
