    Do not smoke when refueling, and keep away from sparks, flames, or other sources of ignition. Stop engine before refueling. Refuel in a well-ventilated area. Refuel portable fuel tanks off the boat. Do not overfill the fuel tank. Take care not to spill gasoline, if gasoline spills, wipe it up immediately. Tighten the filler cap securely after refueling.
  • Page 6 Improper mounting of the outboard motor could result in hazardous conditions. For permanently mounted models, your dealer or other person experienced in proper rigging should mount the motor. If you are mounting the motor yourself, you should be trained by an experienced person. For portable models, your dealer or other person experienced in proper outboard motor mounting should show you how to mount your motor.
  • Page 7 2. If the engine restraint cable attachment is equipped on your engine, an engine restraint cable or chain should be used. Attach to a secure mounting point on the boat to avoid the engine being completely lost if it accidentally falls off the transom.
  • Page 8 Engine Check the engine and engine mounting. Look for loose or damaged fasteners. Check the propeller for damage. Checking the Engine Oil Level 1. Put the outboard motor in an upright position (not tilted). (A) 2. Check the oil level using the oil level check window (B) to be sure the level falls between the upper and lower marks.
  • Page 9 Starting Engine 1. Loosen the air vent screw on the fuel tank cap. One turn for built-in tank. (D) 2. Open the fuel cock. (E) 3. Place the gear shift lever in neutral. (F) NOTE: Attach the engine stop switch lanyard to secure place on your clothing, or your arm or leg.
  • Page 10 When the engine is cold, it needs to be warmed up. If the engine does not start on the first try, repeat the procedure. If the engine fails to start after 4- 5 tries, open the throttle (between 1/8 and 1/4), and try again. Warming up Engine 1.
  • Page 11 1. Place the throttle trip in the fully closed position. (N) 2. Turning the outboard motor around 180° . 3. Move the gear shift lever quickly and firmly from neutral to reverse. (O) NOTE: The outboard motor can turn 360° in its bracket (full-pivot system). The boat can also be backed up by simply turning the outboard motor around 180°...
  • Page 12 1. Push and hold the engine stop button until the engine comes to a complete stop. (S) NOTE: If the outboard motor is equipped with an engine stop switch lanyard, the engine can also be stopped by pulling the lanyard and removing the lock plate from the engine stop switch. 2.
  • Page 13 Be sure all people are clear of the outboard motor when tilting up and down, also be careful not to pinch any body parts between the drive unit and engine bracket. Tighten the air vent screw and place the fuel cock in the closed position if the outboard motor will be tilted for more than a few minutes.
  • Page 14 If there is too much resistance it could be difficult to steer, which could result in an accident. Cruising in Shallow Water The outboard motor can be tilted up partially to allow operation in shallow water. The tilt lock mechanism does not work while the shallow water cruising system is being used. Run the boat at the lowest possible speed to avoid the outboard motor being lifted out of the water, resulting in loss of control.
  • Page 15 Greasing In order to protect the moving spare parts and keep them in good condition, apply grease regularly by using a grease gun at the fitting positions above. Cleaning and Adjusting Spark Plug BR6HS You should periodically remove and inspect the spark plug because heat and deposits will cause the spark plug to slowly break down and erode.
  • Page 16 2. Verify whether the idle speed is set to specification. Idle speed:1,900 ± 100 RPM Correct idling speed inspection is only possible if the engine is fully warmed up. If not warmed up fully, the idle speed will measure higher than normal. Changing Engine Oil Avoid draining the engine oil immediately after stopping the engine.
  • Page 17 Checking Propeller Before inspecting, removing or installing the propeller, always take actions to ensure the engine will not accidentally starts, such as removing the spark plug caps from the spark plugs, placing the shift control in neutral, and removing the lanyard from the engine stop switch, etc. Serious accident could occur if the engine starts when you are nearby.
  • Page 18 Changing gear oil Be sure the outboard motor is securely fastened to the transom or a stable stand. Never get under the lower unit while the outboard motor is tilted, even when the tilt support lever or knob is locked. Serious injury could occur if the motor falls.
  • Page 19 Checking and Replacing Anode(s) Inspect the external anodes periodically. Remove scales from the surfaces of the anodes. Do not paint anodes, as this would render them ineffective and can cause more rapid engine corrosion. Checking Top Cowling Check the fitting of the top cowling by pushing it with both hands. If it is loose have it repaired. Maintenance Table When utilized under normal condition, maintained and repaired in the proper manner, the motor can work normally within the normal life period.
