  • Page 20: Propeller Selection

    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 pro- pellers 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.
  • Page 21 NOTE: At full throttle and under a maximum boat load, the engine’s rpm should be within the upper half of the full throttle operating range, as listed in “SPECIFICATIONS” on page 4-1. Select a propeller which fulfills this require- ment. If operating under conditions which allow the engine’s rpm to rise above the maximum recommended range (such as light boat loads), reduce the throttle setting...

  • Page 34: Installation

    EMU00175 INSTALLATION CAUTION: Incorrect engine height or obstructions to smooth water flow (such as the design or condition of the boat or accessories such as transom ladders/depth finder transducers) can create airborne water spray while the boat is cruising. Severe engine damage may result if the motor is operated continuously in the presence of airborne water spray.

  • Page 35: Mounting The Outboard Motor

    EMU01478¯ MOUNTING THE OUTBOARD MOTOR WARNING Overpowering boat cause severe instability. Do not install an out- board motor with more horsepower than the maximum rating on the capac- ity plate of the boat. If the boat does not have a capacity plate, consult the boat manufacturer.
  • Page 36 EMU01298 Mounting Height To run your boat at optimum efficiency, the water-resistance (drag) of the boat and out- board motor must be made as little as possi- ble. The mounting-height of the outboard motor greatly affects the water-resistance. If the mounting-height is too high, cavitation tends to occur, thus reducing the propulsion;...

  • Page 37: Clamping The Outboard Motor

    EMU00183 CLAMPING THE OUTBOARD MOTOR 1) Place the outboard on the transom so that it is positioned as close to the cen- ter as possible. Tighten the transom clamp screws evenly and securely. Check the clamp-screws for tightness occasionally during operation of the motor as they can work loose due to engine vibration.

  • Page 38: Pre-Operation Checks

    EMU00204 PRE-OPERATION CHECKS WARNING 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. CAUTION: Do not start the engine out of water. Overheating and serious engine damage can occur.

  • Page 39: Checking The Engine Oil Level

    EMU00209 Controls Check throttle, shift, and steering for proper operation before starting the engine. The controls should work smoothly, with- out binding or unusual free play. Look for loose or damaged connections. Check operation of the starter and stop switches when the outboard motor is in the water.

  • Page 40: Filling Fuel

    While many additives available may reduce deposits, Yamaha recommends the use of Ring Free Fuel Additive, available from your Yamaha dealer. Ring Free has repeatedly proven its ability to clean combustion depos- its from inside the engine, notably the critical piston-ring-land area, and fuel system com- ponents.

  • Page 41: 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 surfaces of moving parts to wear-in evenly. Correct break-in (running-in) will help ensure proper performance and longer engine life. CAUTION: Failure to follow the break-in (running-in) procedure may result in reduced engine life or even severe engine damage.

  • Page 42: Starting Engine

    EMU01734 STARTING ENGINE WARNING Before starting the engine, make sure that the boat is tightly moored and that you can steer clear of any obstruc- tions. Be sure there are no swimmers in the water near you. When the air vent screw is loosened, gasoline (petrol) vapor...

    EMU00261 SHIFTING WARNING Before shifting, make sure there are no swimmers or obstacles in the water near you. CAUTION: 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).

  • Page 47: Stopping Engine

    EMU00273¯ STOPPING ENGINE EMU01737 1) Place the throttle control grip in the fully closed position. 2) Place the gear-shift lever in the neutral position. 3) Push and hold the engine stop button until the engine comes to a complete stop. 4) After stopping the engine, set the fuel cock to the closed position.

  • Page 48: 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. The cor- rect trim angle depends upon the combina- tion of boat, engine, and propeller.

  • Page 49: Adjusting Trim Angle

    ADJUSTING TRIM ANGLE EMU01738 Manual tilt model There are 4 holes provided in the clamp bracket to adjust the outboard motor trim angle. 1) Stop the engine. 2) Loosen the trim angle adjusting rod nut, and then remove the trim angle adjust- ing rod 1 while tilting the motor up.
  • Page 50 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 51: Tilting Up/Down

    EMU01739 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 pro- peller and casing from damage by collision with obstructions, and also to reduce salt corrosion.

  • Page 52: Procedure For Tilting Up

    EMU01740 PROCEDURE FOR TILTING UP 1) Tighten the air vent screw(s). 2) Place the fuel cock in the closed posi- tion. 3) Place the gear shift lever in Neutral and face the motor forward. 4) Hold the rear handle and tilt the engine up fully until the tilt support lever auto- matically turns to the locked position.
