  • Page 42 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 43: Clamping The Outboard Motor

    EMU01318 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 44: Breaking In (Running In) Engine

    EMF50312 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 45: Pre-Operation Checks

    EMF40013 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 46: Checking The Engine Oil Level

    EMF43010 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 47: 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 48: 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 902053 water near you. 8 When the air vent screw is loosened, gasoline (petrol) vapor will be released.
  • Page 49 EMU01497 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. 406023* 5) Attach the engine stop switch lanyard to a secure place on your clothing, or your arm or leg.
  • Page 50 EMF63112* Manual start model 7) Pull out the choke knob completely. After the engine starts, return the knob to the original position. NOTE: 8 It is not necessary to use the choke when restarting a warm engine. 8 If the choke knob is left pulled out after 226011 the engine starts, the engine will stall.
  • Page 51 EMF63511* Electric start model 7) Pull out the choke knob completely. After the engine starts, return the choke knob to the original position. NOTE: 8 It is not necessary to use the choke when restarting a warm engine. 8 If the choke knob is left pulled out, the 226011 engine will stall.

  • Page 54 8 Do not turn the main switch to “START” when the engine is running. 8 Do not keep the starter-motor turning for more than 5 seconds. The battery will rapidly become exhausted and it will be impossible for it to start the engine.

  • 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. Otherwise, the boat may become unsta- ble, which could result in loss of control and an accident. 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.

  • 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 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 61 EMU01414 Power Tilt Model 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. 701034 8 Use caution when trying a trim position for the first time.
  • Page 62 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 63: 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. EMH10111 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...
