Safety information EMU33623
Outboard motor safety Observe these precautions at all times. EMU36502
Propeller People can be injured or killed if they come in contact with the propeller. The propeller can keep moving even when the motor is in neutral, and sharp edges of the propeller can cut even when stationary. Stop the engine when a person is in the
water near you. Keep people out of reach of the propeller,
even when the engine is off. EMU40272
Rotating parts Hands, feet, hair, jewelry, clothing, personal flotation device (PFD) straps, etc., can be- come entangled with internal rotating parts of the engine, resulting in serious injury or death. Keep the top cowling in place whenever pos- sible. Do not remove or replace the top cowl- ing with the engine running. Only operate the engine with the top cowling removed according to the specific instruc- tions in the manual. Keep hands, feet, hair, jewelry, clothing, PFD straps, etc., away from any exposed moving parts. EMU33641
Hot parts During and after operation, engine parts are hot enough to cause burns. Avoid touching any parts under the top cowling until the en- gine has cooled. EMU33651
Electric shock Do not touch any electrical parts while start- ing or operating the engine. They can cause shock or electrocution.
EMU33661
Power trim and tilt Body parts can be crushed between the mo- tor and the clamp bracket when the motor is trimmed or tilted. Keep body parts out of this area at all times. Be sure no one is in this area before operating the power trim and tilt mechanism. The power trim and tilt switches operate even when the main switch is off. Keep peo- ple be away from the switches whenever working around the motor. Never get under the lower unit while it is tilt- ed, even when the tilt support lever is locked. Severe injury could occur if the outboard mo- tor accidentally falls. EMU33672
Engine shut-off cord (lanyard) Attach the engine shut-off cord so that the engine stops if the operator falls overboard or leaves the helm. This prevents the boat from running away under power and leaving people stranded, or running over people or objects. Always attach the engine shut-off cord to a secure place on your clothing or your arm or leg while operating. Do not remove it to leave the helm while the boat is moving. Do not at- tach the cord to clothing that could tear loose, or route the cord where it could be- come entangled, preventing it from function- ing. Do not route the cord where it is likely to be accidentally pulled out. If the cord is pulled during operation, the engine will shut off and you will lose most steering control. The boat could slow rapidly, throwing people and ob- jects forward. EMU33811
Gasoline Gasoline and its vapors are highly flam- mable and explosive. Always, refuel ac-
6HB-9-30-E0.book 1

cording to the procedure on page 59 to reduce the risk of fire and explosion. EMU33821
Gasoline exposure and spills Take care not to spill gasoline. If gasoline spills, wipe it up immediately with dry rags. Dispose of rags properly. If any gasoline spills onto your skin, immedi- ately wash with soap and water. Change clothing if gasoline spills on it. If you swallow gasoline, inhale a lot of gaso- line vapor, or get gasoline in your eyes, get immediate medical attention. Never siphon fuel by mouth. EMU33901
Carbon monoxide This product emits exhaust gases which con- tain carbon monoxide, a colorless, odorless gas which may cause brain damage or death when inhaled. Symptoms include nausea, dizziness, and drowsiness. Keep cockpit and cabin areas well ventilated. Avoid blocking exhaust outlets. EMU33781
Modifications Do not attempt to modify this outboard mo- tor. Modifications to your outboard motor may reduce safety and reliability, and render the outboard unsafe or illegal to use. EMU33741
Boating safety This section includes a few of the many im- portant safety precautions that you should follow when boating. EMU33711
Alcohol and drugs Never operate after drinking alcohol or taking drugs. Intoxication is one of the most com- mon factors contributing to boating fatalities. EMU40281
Personal flotation devices (PFDs) Have an approved PFD on board for every
occupant. Yamaha recommends that you must wear a PFD whenever boating. At a minimum, children and non-swimmers should always wear PFDs, and everyone should wear PFDs when there are potentially hazardous boating conditions. EMU33732
People in the water Always watch carefully for people in the wa- ter, such as swimmers, skiers, or divers, whenever the engine is running. When someone is in the water near the boat, shift into neutral and stop the engine. Stay away from swimming areas. Swimmers can be hard to see. The propeller can keep moving even when the motor is in neutral. Stop the engine when a person is in the water near you. EMU33752
Passengers Consult your boat manufacturers instruc- tions for details about appropriate passenger locations in your boat and be sure all pas- sengers are positioned properly before ac- celerating and when operating above an idle speed. Standing or sitting in non-designated locations may result in being thrown either overboard or within the boat due to waves, wakes, or sudden changes in speed or direc- tion. Even when people are positioned prop- erly, alert your passengers if you must make any unusual maneuver. Always avoid jump- ing waves or wakes. EMU33762
Overloading Do not overload the boat. Consult the boat capacity plate or boat manufacturer for max- imum weight and number of passengers. Be sure that weight is properly distributed ac- cording to the boat manufacturers instruc- tions. Overloading or incorrect weight distribution can compromise the boats han-
6HB-9-30-E0.book 2

dling and lead to an accident, capsizing or swamping. EMU33773
Avoid collisions Scan constantly for people, objects, and oth- er boats. Be alert for conditions that limit your visibility or block your vision of others.
Operate defensively at safe speeds and keep a safe distance away from people, ob- jects, and other boats. Do not follow directly behind other boats or
waterskiers. Avoid sharp turns or other maneuvers that
make it hard for others to avoid you or un- derstand where you are going.
Avoid areas with submerged objects or shallow water.
Ride within your limits and avoid aggres- sive maneuvers to reduce the risk of loss of control, ejection, and collision.
Take early action to avoid collisions. Re- member, boats do not have brakes, and stopping the engine or reducing throttle can reduce the ability to steer. If you are not sure that you can stop in time before hitting an obstacle, apply throttle and turn in another direction.
EMU33791
Weather Stay informed about the weather. Check weather forecasts before boating. Avoid
boating in hazardous weather. EMU44161
Accident reporting Boat operators are required by law to file a Boating Accident Report with their boating law enforcement agency if their boat is in- volved in any of the following accidents: 1. There is loss of life or probable loss of
life. 2. There is personal injury that requires
medical attention beyond first aid. 3. There is property damage to boats or
other property over a certain amount. 4. There is complete loss of a boat. Contact local law enforcement personnel if a report is necessary. EMU44171
Boat education and training For U.S.A. Operators should take a boating safety course. This may be required in your state. Many of the organizations listed in the next section can provide information about cours- es in your area. You may also want to consider an Internet- based program for basic boater education. The Online Boating Safety Course provided by the BoatU.S. Foundation, is approved by the National Association of State Boating Law Administrators (NASBLA) and recog- nized by the United States Coast Guard. Most, but not all, states accept this course to meet their minimum requirements. While it cannot replace an in-depth course such as one offered by the U.S. Coast Guard, U.S. Power Squadron, or other organization, this online course does provide a general over- view of the basics in boating safety, require- ments, navigation, and operation. Upon successful completion of the course, the user can download a certificate of comple- tion immediately or, for a small charge, re-
ZMU06025

quest one by mail. To take this free course, go to boatus.org. For Canada All operators of pleasure craft must illustrate competency by means of a Pleasure Craft Operators Card with the exception of Per- sonal Water Craft used for rental purposes which require a rental checklist be complet- ed. Pleasure Craft Operators Cards can be obtained following the completion of a com- petency course, with an on-line option. De- tails can be found on Transport Canadas website. www.tc.gc.ca EMU33881
Passenger training Make sure at least one other passenger is trained to operate the boat in the event of an emergency. EMU33891
Boating safety publications Be informed about boating safety. Additional publications and information can be obtained from many boating organizations. EMU33591
Laws and regulations Know the marine laws and regulations where you will be boating- and obey them. Several sets of rules prevail according to geographic location, but all are basically the same as the International Rules of the Road. The rules presented in the following section are con- densed- and have been provided for your convenience only. Contact the U.S. Coast Guard, the National Association of State Boating Law Adminis- trators, or your local Power Squadron for a complete set of rules governing the waters in which you will be using your boat.

EMU33692
Basic boating rules (Rules of the road)
Just as there are rules that apply when you are driving on streets and highways, there are waterway rules that apply when you are driving your boat. These rules are used inter- nationally. (For U.S.A.: and are also en- forced by the United States Coast Guard and local agencies.) You should be aware of these rules, and follow them whenever you encounter another vessel on the water. EMU33702
Steering and sailing rules and sound signals Whenever two vessels on the water meet one another, one vessel has the right-of- way; it is called the stand-on vessel. The vessel that does not have the right-of-way is called the give-way or burdened vessel. These rules determine which vessel has the right-of-way, and what each vessel should do.
Stand-on vessel The vessel with the right-of-way has the duty to continue its course and speed, except to
avoid an immediate collision. When you maintain your direction and speed, the other vessel will be able to determine how best to avoid you.
Give-way vessel The vessel that does not have the right-of- way has the duty to take positive and timely action to stay out of the way of the Stand-On vessel. Normally, you should not cross in front of the vessel with the right-of-way. You should slow down or change directions brief- ly and pass behind the other vessel. You should always move in such a way that the 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 naviga- tion and collision, and to any special circum- stances, which may render a departure from the above rules necessary in order to avoid immediate danger. In other words, follow the standard rules ex- cept when a collision will occur unless both vessels try to avoid each other. If that is the case, both vessels become Give-Way ves- sels. EMU25522
Rules when encountering vessels There are three main situations that you may encounter with other vessels which could lead to a collision unless the Steering Rules are followed: Meeting: (you are approaching another ves- sel head-on) Crossing: (you are traveling across the oth- er vessels path) Overtaking: (you are passing or being passed by another vessel)
6HB-9-30-E0.book 5
Safety information
6
In the following illustration, your boat is in the center. You should give the right-of-way to any vessels shown in white area (you are the Give-Way vessel). Any vessels in the shad- ed area must yield to you (they are the Give- Way vessels). Both you and the meeting vessel must alter course to avoid each other.
Meeting If you are meeting another power vessel head on, and are close enough to run the risk of collision, neither of you has the right-of- way Both of you should alter course to avoid an accident. You should keep the other ves- sel on your port (left) side. This rule doesnt apply if both of you will clear one another if you continue on your set course and speed.
Crossing When two power driven vessels are crossing each others path close enough to run the risk of collision, the vessel which has the oth- er on the starboard (right) side must keep out
of the way of the other. If the other vessel is on your right, you must keep out of its way; you are the Give-Way vessel. If the other vessel is on your port (left) side, remember that you should maintain course and direc- tion, provided the other vessel gives you the right-of-way as it should.
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 an- other vessel is passing you, you should maintain your speed and direction so that the other vessel can steer itself around you. EMU25532
Other special situations There are three other rules you should be aware of when driving your boat around oth- er 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 power- driven vessel is preparing to go around a bend that may obstruct the view of other wa- ter vessels, the operator should sound a pro- longed blast on the whistle (4 to 6 seconds). If another vessel is around the bend, it too should sound the whistle. Even if no reply is
6HB-9-30-E0.book 6
Safety information
7
heard, however, the vessel should still pro- ceed around the bend with caution. If you navigate such waters with your boat, you will need to carry a portable air horn, available from local marine supply stores. Fishing vessel right-of-way All vessels that are fishing with nets, lines or trawls are considered to be fishing vessels under the International Rules. Vessels with trolling lines are not considered fishing ves- sels. Fishing vessels have the right-of-way regardless of position. Fishing vessels can- not, however, impede the passage of other vessels in narrow channels. Sailing vessel right-of-way Sailing vessels should normally be given the right-of-way. The exceptions to this are: 1. When the sailing vessel is overtaking the
power-driven vessel, the power-driven vessel has the right-of-way.
2. Sailing vessels should keep clear of any fishing vessel.
3. In a narrow channel, a sailing vessel should not hamper the safe passage of a power-driven vessel that can navigate only in such a channel.
Reading buoys and other markers The waters of the United States are marked for safe navigation by the lateral system of buoyage. Simply put, buoys and markers have an arrangement of shapes, colors, numbers and lights to show which side of the buoy a boater should pass on when navigat- ing in a particular direction. The markings on these buoys are oriented from the perspec- tive of being entered from seaward (the boat- er is going towards the port). This means that red buoys are passed on the starboard (right) side when proceeding from open wa- ter into port, and black buoys are to port (left) side. When navigating out of port, your posi-
tion with respect to the buoys should be re- versed; red buoys should be to port and black buoys to starboard. Many bodies of water used by boaters are entirely within the boundaries of a particular state. The Uniform State Waterway Marking System has been devised for these waters. This system uses buoys and signs with dis- tinctive 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 geo- graphic location. Always consult local boat- ing authorities before driving your boat in unfamiliar waters.

device (PFD). Attach engine shut-off cord (lanyard) to
your PFD, arm, or leg so the engine
stops if you accidentally leave the helm, which could prevent a runaway boat.

Installation requirements EMU33565
Boat horsepower rating
WARNING EWM01561
Overpowering a boat can cause severe instability.
Before installing the outboard motor(s), con- firm that the total horsepower of your out-
board motor(s) does not exceed the boats maximum horsepower rating. See the boats capacity plate or contact the manufacturer. EMU40491
Mounting outboard motor
WARNING EWM02501
Improper mounting of the outboard mo- tor could result in hazardous condi- tions such as poor handling, loss of control, or fire hazards.
Because the outboard motor is very heavy, special equipment and training is required to mount it safely.
Your dealer or other person experienced in proper rigging should mount the outboard motor using correct equipment and complete rigging instructions. For further information, see page 50. EMU33582
Remote control requirements
WARNING EWM01581
If the engine starts in gear, the boat can move suddenly and unexpectedly, pos- sibly causing a collision or throwing passengers overboard.
If the engine ever starts in gear, the start-in-gear protection device is not working correctly and you should dis- continue using the outboard. Contact your Yamaha dealer.
The remote control unit must be equipped with a start-in-gear protection device(s). This device prevents the engine from starting un- less it is in neutral. EMU25695
Battery requirements EMU44723

maintenance-free batteries are permitted. Use a fully charged battery that meets the following specifications. The battery is an im- portant component necessary to obtain sure engine starting and to maintain engine per- formance. The engine may not start if the battery volt- age is too low. For North America It is necessary to meet only two of the three specifications (CCA, MCA, and RC) in one of the following combinations: CCA/SAE and RC MCA/ABYC and RC
For Oceania It is necessary to meet the following specifi- cations.
NOTICE ECM01063
Do not use a battery that does not meet the specified capacity. If a battery that does not meet specifications is used, the electric system could perform poor- ly or be overloaded, causing electric system damage.
Do not use a battery which exceeds the maximum CCA rating. If the batteries are used in parallel circuit, use new bat- teries of the same type and make sure that the total battery rating never ex-
ceed the maximum CCA rating.
EMU36293
Mounting battery Mount the battery holder securely in a dry, well-ventilated, vibration-free location in the boat. WARNING! Do not put flammable items, or loose heavy or metal objects in the same compartment as the battery. Fire, explosion or sparks could result. [EWM01821]
Battery cable The battery cable size and length are critical. Consult your Yamaha dealer about the bat- tery cable size and length. EMU36303
Multiple batteries To connect multiple batteries, such as for multiple engine configurations or for an ac- cessory battery, consult your Yamaha dealer about battery selection and correct wiring. Battery isolator Your outboard motor is capable of charging an accessory battery separate from the start- ing battery using an optional isolator lead. Contact your Yamaha dealer for installation of an optional isolator lead with over-current protection. EMU41603
Propeller selection Next to selecting an outboard motor, select- ing the right propeller is one of the most im- portant purchasing decisions a boater can make. The type, size, and design of your pro- peller have a direct impact on acceleration, top speed, fuel economy, and even engine life. Yamaha designs and manufactures pro- pellers for every Yamaha outboard motor and every application. Your Yamaha dealer can help you select the right propeller for your boating needs. Select
