General information operator of the other vessel can see what you are doing. “The general prudential rule” This rule is called Rule 2 in the International Rules and says, “In obeying and construing these rules due regard shall be had to all dangers of navigation and collision, and to any special circumstances, which may render a departure from the above rules necessary in order to avoid immediate danger.
General information Overtaking If you are passing another vessel, you are the “Give-Way” vessel. This means that the other vessel is expected to maintain its course and speed. You must stay out of its way until you are clear of it. Likewise, if another vessel is passing you, you should maintain your speed and direction so that the other vessel can steer itself around you. EMU25530 Other special situations There are three other rules you should be aware of when driving your boat around other vessels.
General information This system uses buoys and signs with distinctive shapes and colors to show regulatory or advisory information. These markers are white with black letters and orange boarders. They signify speed zones, restricted areas, danger areas, and general information. Remember, markings may vary by geographic location. Always consult local boating authorities before driving your boat in unfamiliar waters.
General information ZMU01708 EMU25540 Fueling instructions EWM00010 WARNING GASOLINE AND ITS VAPORS ARE HIGHLY FLAMMABLE AND EXPLOSIVE! ● 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. Take care not to spill gasoline.
General information ● ● ● ● ● dry rags. Do not overfill the fuel tank. Tighten the filler cap securely after refueling. If you should swallow some gasoline, inhale a lot of gasoline vapor, or get gasoline in your eyes, get immediate medical attention. If any gasoline spills onto your skin, immediately wash with soap and water. Change clothing if gasoline spills on it. Touch the fuel nozzle to the filler opening or funnel to help prevent electrostatic sparks.

Operation EMU26901 Installation ECM00110 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 or 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. NOTE: During water testing check the buoyancy of the boat, at rest, with its maximum load.
Operation motor greatly affects the water resistance. If the mounting height is too high, cavitation tends to occur, thus reducing the propulsion; and if the propeller tips cut the air, the engine speed will rise abnormally and cause the engine to overheat. If the mounting height is too low, the water resistance will increase and thereby reduce engine efficiency. Mount the outboard motor so that the anti-cavitation plate is in alignment with the bottom of the boat. life.
Operation 3. 4. 5. throttle to 3000 r/min or less. Next two hours: Accelerate at full throttle onto plane, then reduce engine speed to three-quarter throttle (approximately 4000 r/min). Vary engine speed occasionally. Run at full throttle for one minute, then allow about 10 minutes of operation at threequarter throttle or less to let the engine cool. Remaining seven hours: Run the engine at any speed. However, avoid operating at full throttle for more than 5 minutes at a time.
Operation pipes. After any air in the oil lines has been expelled, the oil injection system should supply oil normally. If no oil is flowing after 10 minutes of idling, consult your Yamaha dealer. ZMU03907 ECM00130 CAUTION: Be sure to take the above steps when operating the engine after a long period of storage. Otherwise engine seizure could occur.
Operation 1. Pour engine oil into the remote oil tank. Remote oil tank capacity: 10.5 L (11.10 US qt) (9.24 Imp.qt) ZMU01877 NOTE: The oil level lines on the remote oil tank indicate the amount of additional oil that can be added to the tank. The top oil level line indicates approximately 1.9 L (0.5 US gal, 0.4 Imp gal) can be added, and the bottom oil level line indicates approximately 3.8 L (1 US gal, 0.8 Imp gal) can be added. 2. 3.

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. When the air vent screw is loosened, gasoline vapor will be released. Gasoline is highly flammable, and its vapors are flammable and explosive.
Operation ● ● your arm or leg while operating. Do not attach the lanyard to clothing that could tear loose. Do not route the lanyard where it could become entangled, preventing it from functioning. Avoid accidentally pulling the lanyard during normal operation. Loss of engine power means the loss of most steering control. Also, without engine power, the boat could slow rapidly. This could cause people and objects in the boat to be thrown forward. N ZMU02314 NOTE: ● ● 5. 3.

ECM00191 CAUTION: ● ● Never turn the main switch to “ ” (start) while the engine is running. Do not keep the starter motor turning for more than 5 seconds. If the starter motor is turned continuously for more than 5 seconds, the battery will be quickly discharged, thus making it impossible to start the engine.
Operation EMU27764 Forward (tiller handle and remote control models) Tiller handle models 1. Place the throttle grip in the fully closed position. 2. Move the gear shift lever quickly and firmly from neutral to forward. Remote control models 1.

Operation ● ● board motor when adjusting the tilt angle, also be careful not to pinch any body parts between the drive unit and clamp bracket. Use caution when trying a trim position for the first time. Increase speed gradually and watch for any signs of instability or control problems. Improper trim angle can cause loss of control. If equipped with a power trim and tilt switch located on the bottom cowling, use the switch only when the boat is at a complete stop with the engine off.
Operation salt corrosion. EWM00220 WARNING 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. EWM00250 WARNING Bow Down Too much trim-in causes the boat to “plow” through the water, decreasing fuel economy and making it hard to increase speed. Operating with excessive trim-in at higher speeds also makes the boat unstable.
Operation 2. 3. Disconnect the fuel line from the outboard motor or close the fuel cock. Press the power trim and tilt switch / power tilt switch “ ” (up) until the outboard motor has tilted up completely. to support it with the tilt support knob or tilt support lever. Otherwise the outboard motor could fall back down suddenly if oil in the power trim and tilt unit loses pressure. 5.
