Otherwise, engine damage could result from leaking oil. EMU25500 Basic boating rules (Rules of the road) Just as there are rules which apply when you are driving on streets and high ways, there are waterway rules which apply when you are driving your boat.
General information sels. EMU25520 Rules when encountering vessels There are three main situations which you may encounter with other vessels which could lead to a collision unless the Steering Rules are followed: Meeting: (you are approaching another vessel head-on) Crossing: (you are traveling across the other vessel’s path) Overtaking: (you are passing or being passed by another vessel) In the following illustration, your boat is in the center.
General information EMU25530 Other special situations There are three other rules you should be aware of when driving your boat around other vessels. Narrow channels and bends When navigating in narrow channels, you should keep to the right when it is safe and practical to do so. If the operator of a powerdriven vessel is preparing to go around a bend that may obstruct the view of other water vessels, the operator should sound a prolonged blast on the whistle (4 to 6 seconds).

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.

Consult your Yamaha dealer if the problem cannot be located and corrected. EMU26816 Overheat warning This engine has an overheat warning device. If the engine temperature rises too high, the warning device will activate. Activation of warning device ● The engine speed will automatically decrease to about 2000 r/min.
Basic components indicator, it will light or blink. ZMU03609 ● The buzzer will sound (if equipped on the tiller handle, remote control box, or main switch panel). If the warning system has activated, stop the engine as soon as it is safe to do so. Check the oil level and add oil as needed. If the oil level is correct and the warning device does not switch off, consult your Yamaha dealer. ECM00100 CAUTION: Do not continue to run the engine if the low oil pressure warning indicator is on.
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.
Operation ● ● ● line fumes. Check fuel line connections to be sure they are tight (if equipped Yamaha fuel tank or boat tank). Be sure the fuel tank is positioned on a secure, flat surface, and that the fuel line is not twisted or flattened, or likely to contact sharp objects (if equipped Yamaha fuel tank or boat tank). Check the water in the fuel filter with the water separator warning device. Place the gear shift lever in neutral and turn the main switch to “ ”(on).
Operation 1. 2. 3. Remove the fuel tank cap. Carefully fill the fuel tank. Securely close the cap after filling the tank. Wipe up any spilled fuel. Fuel tank capacity: 24 L (6.34 US gal) (5.28 Imp.gal) tive has repeatedly proven its ability to clean combustion deposits from inside the engine, notably the critical piston-ring-land area, and fuel system components. Follow product labeling for use instructions.
Operation from the fuel tank. 4. Squeeze the primer pump with the outlet end up until you feel it become firm. ZMU02295 2. If there is a fuel joint on the motor, firmly connect the fuel line to the joint. Then firmly connect the other end of the fuel line to the joint on the fuel tank. ZMU02025 EMU27490 Starting engine EMU27592 Electric start / prime start models 1. Place the gear shift lever in neutral.
Operation ● ● to a secure place on your clothing, or 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. 5.
Operation NOTE: The start-in-gear protection device prevents the engine from starting except when in neutral. 2. 3. 4. Turn the main switch to “ ” (on). Turn the main switch to “ ” (start), and hold it for a maximum of 5 seconds. 5. Immediately after the engine starts, release the main switch and allow it to return to “ ” (on). Attach the engine stop switch lanyard to a secure place on your clothing, or your arm or leg.
Operation again. NOTE: ● ● When the engine is cold, it needs to be warmed up. For further information, see page 42. If the engine is warm and fails to start, open the throttle slightly and try to start the engine again. If the engine still fails to start, see page 73. cooling water pilot hole is blocked. Consult your Yamaha dealer if the problem cannot be located and corrected. EMU27670 Warming up engine EMU27710 Manual start and electric start models 1.
Operation EMU27785 Reverse (automatic reverse lock and power trim and tilt models) EWM00190 WARNING When operating in reverse, go slowly. Do not open the throttle more than half. Otherwise the boat could become unstable, which could result in loss of control and an accident. 2. Move the gear shift lever quickly and firmly from neutral to forward. Remote control models 1. Pull up the neutral interlock trigger (if equipped) and move the remote control lever quickly and firmly from neutral to forward.
Operation or when the engine speed exceeds approximately 3000 r/min. EMU27820 Stopping engine Before stopping the engine, first let it cool off for a few minutes at idle or low speed. Stopping the engine immediately after operating at high speed is not recommended. EMU27844 Procedure EMU30880 Trolling 1. Push and hold the engine stop button or turn the main switch to “ ” (off). 2. After stopping the engine, disconnect the fuel line if there is a fuel joint on the outboard motor.
Operation the boat, sea conditions, and running speed. EWM00740 WARNING ZMU03632 3. Tighten the air vent screw on the fuel tank cap (if equipped). Excessive trim for the operating conditions (either trim up or trim down) can cause boat instability and can make steering the boat more difficult. This increases the possibility of an accident. If the boat begins to feel unstable or is hard to steer, slow down and/or readjust the trim angle. ZMU02301 4. Remove the key if the boat will be left unattended.
Operation ● ● 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. Do not adjust the trim angle with this switch while the boat is moving.
Operation Bow Up Too much trim-out puts the bow of the boat too high in the water. Performance and economy are decreased because the hull of the boat is pushing the water and there is more air drag. Excessive trim-out can also cause the propeller to ventilate, which reduces performance further, and the boat may “porpoise” (hop in the water), which could throw the operator and passengers overboard.
Operation ● on page 44. Never tilt the outboard motor while the engine is running. Severe damage from overheating can result. Do not tilt up the engine by pushing the tiller handle (if equipped) because this could break the handle. EMU28007 Procedure for tilting up (power trim and tilt models / power tilt models) 1.
