Safety information

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 neu- tral, 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 people be away from the switches whenever working around the motor. Never get under the lower unit while it is tilted, even when the tilt support lever is locked. Se- vere injury could occur if the outboard motor 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 peo- ple stranded, or running over people or ob- jects. 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.

U6D63GE0.book Page 2 Friday, December 11, 2015 9:07 AM

EMU33811

Gasoline Gasoline and its vapors are highly flamma- ble and explosive. Always, refuel according to the procedure on page 56 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 some- one 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 passen- gers are positioned properly before acceler- ating 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-

2

Safety information

U6D63GE0.book Page 3 Friday, December 11, 2015 9:07 AM

tions. Overloading or incorrect weight distribution can compromise the boats han- 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, objects, 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 an- other 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

ZMU06025

successful completion of the course, the user can download a certificate of completion im- mediately or, for a small charge, request one by mail. To take this free course, go to boa- tus.org. For Canada All operators of pleasure craft must illustrate competency by means of a Pleasure Craft Operators Card with the exception of Person- al Water Craft used for rental purposes which require a rental checklist be completed. Plea- sure Craft Operators Cards can be obtained following the completion of a competency course, with an on-line option. Details 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 Administra- tors, or your local Power Squadron for a com- plete 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 driv- ing your boat. These rules are used interna- tionally. (For U.S.A.: and are also enforced by the United States Coast Guard and local agencies.) You should be aware of these rules, and follow them whenever you encoun- ter 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)

5

Safety information

U6D63GE0.book Page 6 Friday, December 11, 2015 9:07 AM

Crossing: (you are traveling across the other vessels path) Overtaking: (you are passing or being passed by another vessel) 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 shaded 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 vessel on your port (left) side. This rule doesnt apply if both of you will clear one another if you con- tinue 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 other 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 direction, provid- ed 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 another 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 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 power- driven vessel is preparing to go around a bend that may obstruct the view of other wa-

6

Safety information

U6D63GE0.book Page 7 Friday, December 11, 2015 9:07 AM

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 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, num- bers 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 water into port, and black buoys are to port (left) side. When navigating out of port, your position with respect to the buoys should be reversed; 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 geograph- ic location. Always consult local boating au- thorities before driving your boat in unfamiliar waters.
