  • Page 46 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 47: Breaking In (Running In) Engine

    EMU00224 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. Failure to follow the break-in (running-in) procedure may result in reduced engine life or even severe engine damage.

  • Page 48: 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 49: Checking The Engine Oil Level

    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 50: 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 51: 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 water near you. 8 When the air vent screw is loosened, gasoline (petrol) vapor will be released.

  • Page 55: Warming Up Engine

    Check the oil level and add oil if necessary. If the cause for the low oil pressure warning indicator cannot be found, consult your Yamaha dealer. 8 A continuous flow of water from the pilot hole shows that the water pump is pumping water through the cooling passages.

  • Page 56: Shifting

    EMU00261 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). EMU00265 FORWARD Tiller control model...

  • Page 57: Reverse

    EMU01326 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. 501012 1) Place the throttle control grip in the fully closed position (for Tiller control model).

  • Page 58: 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. 501063 EMU00277 1) Push and hold the engine stop button or turn the main switch to “OFF”.

  • Page 59: 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 60: Adjusting Trim Angle

    ADJUSTING TRIM ANGLE EMU01113* Hydro-tilt Model 8 Stop the engine before adjusting the trim angle. 8 Be sure all people are clear of the out- board motor when adjusting the tilt angle, also be careful not to pinch any body parts between the drive unit and clamp bracket.
  • Page 61 EMU01116* 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 62 EMU00282 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 63: 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 collision with obstructions, and also to 105014 reduce salt corrosion.
  • Page 64 EMU01127 PROCEDURE FOR TILTING UP Hydro-tilt model 1) Remove the fuel-line connection from the motor. 304053 2) Place the tilt-lock lever in the release position. 402076 3) Hold the rear of the top cowling with one hand, tilt the engine up, push the tilt support knob into the clamp brack- et, and place the tilt-lock lever back into the lock position to support the...
  • Page 65 2) Push the power trim/tilt switch “UP” until the outboard has tilted up com- pletely. 701034* 3) Push the tilt support knob into the clamp bracket to support the engine. After tilting the engine, be sure to sup- port it with the tilt support knob. Other- wise, the engine could fall back down suddenly if oil in the power trim/tilt unit should lose pressure.
