General information 2 EMU25362 Safety information Before mounting or operating the outboard motor, read this entire manual. Reading it should give you an understanding of the motor and its operation. Before operating the boat, read any own- er’s or operator’s manuals supplied with it and all labels. Be sure you understand each item before operating. Do not overpower the boat with this out- board motor. Overpowering the boat could result in loss of control. The rated power of the outboard should be equal to or less than the rated horsepower capacity of the boat. If the rated horsepower capacity of the boat is unknown, consult the dealer or boat manufacturer. Do not modify the outboard. Modifications could make the motor unfit or unsafe to use. Incorrect propeller selection and incorrect use may not only cause engine damage, but also adversely affect fuel consumption. Consult your dealer for correct use. Never operate after drinking alcohol or tak- ing drugs. About 50% of all boating fatali- ties involve intoxication. Have an approved personal flotation de- vice (PFD) on board for every occupant. It is a good idea to 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 condi- tions. Gasoline is highly flammable, and its va- pors are flammable and explosive. Handle and store gasoline carefully. Make sure there are no gas fumes or leaking fuel be- fore starting the engine. This product emits exhaust gases which contain carbon monoxide, a colorless, odorless gas which may cause brain dam- age or death when inhaled. Symptoms in- clude nausea, dizziness, and drowsiness. Keep cockpit and cabin areas well ventilat- ed. Avoid blocking exhaust outlets. Check throttle, shift, and steering for prop- er operation before starting the engine. Attach the engine stop switch lanyard cord to a secure place on your clothing, or your arm or leg while operating. If you acciden- tally leave the helm, the cord will pull from the switch, stopping the engine. Know the marine laws and regulations where you will be boating—and obey them. For basic boating rules, see “Rules of the road” on page 4. 1. Manufactured date label location 1 ZMU02838 Manufactured: ZMU04346
General information 3 Stay informed about the weather. Check weather forecasts before boating. Avoid boating in hazardous weather. Tell someone where you are going: leave a Float Plan with a responsible person. Be sure to cancel the Float Plan when you re- turn. Use common sense and good judgment when boating. Know your abilities, and be sure you understand how your boat han- dles under the different boating conditions you may encounter. Operate within your limits, and the limits of your boat. Always operate at safe speeds, and keep a careful watch for obstacles and other traffic. Always watch carefully for swimmers dur- ing the engine operation. Stay away from swimming areas. When a swimmer is in the water near you shift into neutral and shut off the engine. Do not illegally discard empty containers used to replace or replenish oil. For the correct processing of empty containers, consult the dealer where you purchased the oil. When replacing oils used to lubricate the product (engine or gear oil), be sure to wipe away any spilt oil. Never pour oil with- out using a funnel or similar device. If nec- essary, verify the necessary replacement procedure with the dealer. Never illegally discard (dump) the product. Yamaha recommends consulting the deal- er on discarding the product. Be informed about boating safety.

The engine will not start unless the shift control is in neutral position. 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. These rules are used internationally, and are also enforced by the United States Coast Guard and local agen- cies. You should be aware of these rules, and follow them whenever you encounter another vessel on the water. Several sets of rules prevail according to geographic location, but are all basically the same as the International Rules of the Road. The rules presented here in your Owner’s Manual are condensed, and have been pro- vided for your convenience only. Consult your local U.S. Coast Guard Auxiliary or De- partment of Motor Vehicles for a complete set of rules governing the waters in which you will be using your boat. EMU25510 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 which 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 which 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. EMU25520 Rules when encountering vessels There are three main situations which you may encounter with other vessels which
General information 5 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 vessel’s 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 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 doesn’t 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 other’s 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.
