63B-9-19-1 (E) 4/18/01 11:36 AM Page 11 E EMB40010 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 agencies. You should be aware of these rules, and follow them whenever you encounter another vessel on the water.

Likewise, if another vessel is passing you, you should maintain your speed and direction so that the other vessel can steer itself around you. OTHER SPECIAL SITUATIONS There are three other rules you should be aware of when driving your boat around other vessels.

63B-9-19-1 (E) 4/18/01 11:36 AM Page 15 E EMU00016 FUELING INSTRUCTIONS w GASOLINE AND ITS VAPORS ARE HIGHLY FLAMMABLE AND EXPLOSIVE! 8 Do not smoke when refueling, and keep away from sparks, flames, or other sources of ignition. 8 Stop engine before refueling. 8 Refuel in a well-ventilated area. Refuel portable fuel tanks off the boat. 8 Take care not to spill gasoline. If gasoline spills, wipe it up immediately with dry rags. 8 Do not overfill the fuel tank.
63B-9-19-1 (E) 4/18/01 11:36 AM Page 16 E EMU00018 GASOLINE (PETROL) Recommended gasoline: Regular unleaded gasoline with a minimum octane rating of 86 (Pump Octane Number) = (R+M)/2 If knocking or pinging occurs, use a different brand of gasoline or premium unleaded fuel. If unleaded gasoline is not available, then leaded regular gasoline can be used. EMU00027 Gasohol There are two types of gasohol: gasohol containing ethanol and that containing methanol.
63B-9-19-1 (E) 4/18/01 11:36 AM Page 17 E EMU00031 BATTERY REQUIREMENT cC Do not use the battery that does not meet the specified capacity. If different battery from the specification is used, the electric system may perform poorly or be overloaded, causing electrical system damage. Choose battery which meets the following specifications for Electric start model. Minimum cold crank performance 400 Amps at -17.8°C (0°F) Minimum reserve capacity 85 minutes at 26.
63B-9-19-1 (E) 4/18/01 11:36 AM Page 18 E EMU01395 PROPELLER SELECTION The performance of your outboard motor will be critically affected by your choice of propeller, as an incorrect choice could adversely affect performance and could also seriously damage the motor. Engine speed depends on the propeller size and boat load. If engine speed is too high or too low for good engine performance, this will have an adverse effect on the engine.
63B-9-19-1 (E) 4/18/01 11:36 AM Page 19 E NOTE: At full throttle and under a maximum boat load, the engine’s rpm should be within the upper half of the full throttle operating range, as listed in “SPECIFICATIONS” on page 4-1. Select a propeller which fulfills this requirement. If operating under conditions which allow the engine’s rpm to rise above the maximum recommended range (such as light boat loads), reduce the throttle setting to maintain the rpm in the proper operating range.

EMF44010 OPERATION AFTER A LONG PERIOD OF STORAGE (for Precision blend system model) When operating the engine after a long period (12 months) of storage, proceed as follows: 1) Use a 50 : 1 gasoline-oil mixture to start the engine.
63B-9-19-3A (E) 4/18/01 11:38 AM Page 12 E EMF50112 BREAKING IN (RUNNING IN) ENGINE Your new engine requires a period of break-in (running-in) to allow mating surfaces of moving parts to wear-in evenly. Correct break-in (running-in) will help ensure proper performance and longer engine life. cC 8 Failure to follow the break-in (runningin) procedure may result in reduced engine life or even severe engine damage.
63B-9-19-3A (E) 4/18/01 11:38 AM Page 13 E EMU00227 Run the engine under load (in gear with a propeller installed) as follows. 1) First 10 minutes: Run the engine at the lowest possible-speed. A fast idle in neutral is best. 2) Next 50 minutes: Do not exceed half throttle (approximately 3,000 r/min). Vary engine speed occasionally. If you have an easy-planing boat, accelerate at full throttle onto plane, then immediately reduce the throttle to 3,000 r/min or less.
63B-9-19-3A (E) 4/18/01 11:38 AM Page 14 E EMU01147 STARTING ENGINE w 902053 304034 8 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. 8 When the air vent screw is loosened, gasoline (petrol) vapor will be released. Gasoline (petrol) is highly flammable, and its vapors are flammable and explosive.

63B-9-19-3B (E) 4/18/01 11:39 AM Page 6 E EMU01412 TRIMMING OUTBOARD MOTOR The trim angle of the outboard motor helps determine the position of the bow of the boat in the water. The correct trim angle will help improve performance and fuel economy while reducing strain on the engine. The correct trim angle depends upon the combination of boat, engine, and propeller. Correct trim is also affected by variables such as the load in the boat, sea conditions, and running speed.

Increase speed gradually and watch for any signs of instability or control problems.
63B-9-19-3B (E) 4/18/01 11:39 AM Page 9 E EMG62010 Bow up When the boat is on plane, a bow-up attitude result in less drag, greater stability and efficiency. This is generally when the keel line of the boat is up about 3 to 5 degrees. When trimmed out, the boat may have more tendency to steer to one side or the other. Compensate for this as you steer. The trim tab can also be adjusted to help offset this effect. q 105011 w Too much trim-out puts the bow of the boat too high in the water.
63B-9-19-3B (E) 4/18/01 11:39 AM Page 10 E EMH10110 TILTING UP/DOWN If the engine will be stopped for some time, or if the boat is moored in shallows, the engine should be tilted up to protect the propeller and casing from damage by collision with obstructions, and also to reduce salt corrosion. 000817 cC 8 Before tilting the motor, follow the procedures under “STOPPING ENGINE”. Never tilt the motor while the engine is running. Severe damage from overheating can result.

When transporting and storing the outboard motor, close the air vent screw and fuel cock to prevent fuel from leaking. TRAILERING OUTBOARD MOTOR The motor should be trailered and stored in the normal running position. If there is insufficient road clearance in this position, then trailer the motor in the tilt position using a motor support device such as a transom saver bar.
63B-9-19-4 (E) 4/18/01 11:40 AM Page 5 E EMK16010 STORING OUTBOARD MOTOR When storing your Yamaha outboard for prolonged periods of time, (2 months or longer), several important procedures must be performed to prevent expensive damage. This is especially important for your Precision Blend equipped outboard due to the lean oil ratios used at idle prior to shutting the engine off for the season. It is advisable to have your outboard serviced by an authorized Yamaha dealer prior to storage.
63B-9-19-4 (E) 4/18/01 11:40 AM Page 6 E EMK22511 Flushing Cooling System and Fogging Engine Cooling system flushing is essential to prevent the cooling system from clogging up with salt, sand, or dirt. In addition, fogging of the engine is mandatory to prevent expensive engine damage due to rust. Perform the flushing and fogging at the same time. q w 605024 8 Flushing in a water tank 1) Remove the engine top cowling and silencer cover.
63B-9-19-4 (E) 4/18/01 11:40 AM Page 7 E 4) Just prior to turning off the engine, quickly spray “Yamaha Stor-Rite Engine Fogging Oil” (Part No. LUBSTRRT-12-00) alternately into each carburetor. When properly done, the engine will smoke excessively and almost stall. 8 Flushing with the flushing attachment 1) Remove the top cowling and silencer cover. Remove the propeller. 2) Install a flushing attachment to the lower unit. (Flushing attachment available from your Yamaha dealer).
63B-9-19-4 (E) 4/18/01 11:40 AM Page 8 E EMK26112 Lubrication 1) Remove the spark plugs, and spray a 10 second spray of “Yamaha StorRite Engine Fogging Oil” into each cylinder. Grease the spark plug threads and reinstall the spark plugs and torque to proper specification.

The condition of the spark plug can indicate something about the condition of the engine.
63B-9-19-4 (E) 4/18/01 11:40 AM Page 15 E When fitting the plug, always clean the gasket surface and use a new gasket. Wipe off any dirt from the threads and screw in the spark plug to the correct torque. Spark plug torque: Refer to “SPECIFICATIONS”, page 4-1. NOTE: If a torque-wrench is not available when you are fitting a spark plug, a good estimate of the correct torque is 1/4 to 1/2 a turn past finger-tight. Have the spark plug adjusted to the correct torque as soon as possible with a torque-wrench.
