REQUIRED EQUIPMENT

The U.S. Coast Guard (USCG) has regulations which describe minimum standards of safety. You must comply with these regulations, which apply to boats like your Sport Boat which are less than 26 feet long.

" Personal Flotation Devices (PFDs):

Type I, II, or III as required for all people on board (see “Operational Requirements” for more information), plus at least one Type IV (throwable type).

" Fire Extinguisher:

At least one B-1 type hand-held portable fire extinguisher.

" Visual Distress Signals:

It is recommended that a USCGapproved pyrotechnic device be stored on your boat. A mirror can also be used as an emergency signal. Contact your Yamaha dealer or the Coast Guard for more information.

" Sound Signalling Device:

Your Sport Boat is equipped with a horn that can be used to signal other boats. See “Rules of the Road” for more infor mation.

" Navigation Lights:

Your Sport Boat is equipped with navigation lights for use between sunset and sunrise, and during periods of reduced visibility, such as fog.Be sure these lights are working and are turned on when necessary (see page 2-13 and 3-9 for more information).

ADDITIONAL EQUIPMENT RECOMMENDATIONS

The following equipment can help make your boating experience safer and more enjoyable:

" Mooring fenders and lines " Anchor with suitable line (a

“Danforth” type anchor and line that is at least 6-times the depth of the water where you will drop anchor are recommended)

" Manual-type bilge pump " First Aid kit " Waterproof flashlight with extra bat-

teries

" Tool kit with assor ted screwdrivers,

pliers, wrenches (including metric sizes), and electrical tape

" Oar or paddle (look for one with a

boat hook on the other end)

" Spare par ts, such as an extra set of

spark plugs and fuses

" Navigation charts for the waters

where you will be boating

" Tow rope

Page 14

CRUISING LIMITATIONS

" Scan constantly for people, objects,

and other watercraft. Be alert for conditions that limit your visibility or block your vision of others.

" Operate defensively at safe speeds

and keep a safe distance from people, objects, and other watercraft.

" Do not follow directly behind other

boats.

" Do not go near others to spray or

splash them with water.

" Avoid shar p turns or other maneu-

vers that make it hard for others to avoid you or understand where you are going.

" Avoid areas with submerged objects

or shallow water.

" Operate within your limits and avoid

aggressive maneuvers to reduce the risk of loss of control, ejection, and collision.

" This is a high-performance boat –

not a toy. Sharp turns or jumping waves or wakes can increase the

risk of back/spinal injury (paralysis), facial injuries, and broken legs, ankles, and other bones. Do not jump waves or wakes.

" Do not operate the boat in rough

water, bad weather, or when visibility is poor; this may lead to an accident causing injury or death. Be alert to the possibility of bad weather. Take note of weather forecasts and the prevailing weather conditions before setting out in your boat.

" Never operate in water that is less

than 3 ft (90 cm) deep, otherwise you increase your chance of hitting a submerged object, which could result in injury.

" Leave a “float plan” with a responsi-

ble person on shore.Tell where you plan to go and when you plan to arrive, and provide a description of your boat.Advise this person if your plans change and also when you arrive to prevent false alarms. A sample float plan is included on page 6-6.

OPERATIONAL REQUIREMENTS

" All riders must wear a Coast Guard

approved personal flotation device (PFD).

" Eye protection is recommended to

keep wind, water , and glare from the sun out of your eyes while you operate your Sport Boat. Restraining straps for eyewear are made which are designed to float should your eyewear fall into the water.

" Footwear and gloves are recom-

mended.

" NEVER operate the boat after con-

suming alcohol or taking drugs.

" For reasons of safety and proper

care of the Sport Boat, always perform the pre-operation checks listed on page 3-4 before operating.

" Passengers must always sit in a

designated seating area, place feet on the deck, and use the handgrips provided when the boat is in motion.

" Always consult your doctor on

whether it is safe for you to r ide in this boat if you are pregnant or in poor health.

" Do not attempt to modify this Spor t

Boat! Modifications to your boat may reduce safety and reliability, and render the boat unsafe or illegal to use.

" Attach the engine shut-off cord (lan-

yard) to PFD and keep it free from steering wheel or other controls so that the engine stops if the operator accidentally leaves the helm.Failure to attach the engine shut-off cord could result in a runaway boat if the operator is ejected.

After operation, remove the engine shut-off cord and the keys to avoid accidental starting or unauthorized use by children or others.

" Scan constantly for swimmers and

stay away from swimming areas. Swimmers are hard to see and you could accidentally hit someone in the water.

" Avoid being hit by another boat! You

should always take responsibility to watch for other traffic; other boaters may not be watching for you. If they do not see you, or you maneuver more quickly than they expect, you risk a collision.

" Maintain a safe distance from other

boats or watercraft, and also watch for boats’ ski ropes or fishing lines. Obey the “Rules of the Road” (see page 1-15), and be sure to check behind you before making a turn.

HAZARD INFORMATION

" Never start the engine or let it run for

any length of time in an enclosed area. Exhaust fumes contain carbon monoxide, a colorless, odorless gas that may cause death within a short time. Always operate the boat in an open area.

SPORT BO AT CHARACTERISTICS

" Jet thrust turns the Sport Boat.

Pulling the throttle levers completely back to idle produces only minimum thrust. If you are traveling at speeds above trolling, you will have rapidly decreasing ability to steer without throttle. You may still have some turning ability immediately after pulling the throttle levers back to idle, but once the engine slows down, the Sport Boat will no longer respond to steering wheel input until you apply throttle again or you reach a trolling speed. Practice turning in an open area without obstructions until you have a good feel for the maneuver.

" Yamaha Sport Boats are water-jet

propelled. The pumps are directly connected to the engines. This means that the jet thrust will pro-

Page 17

SAFETY INFORMATION 1

1-13

duce some movement whene ver the engines are running.The Sport Boat has a “neutral” position, but since the Sport Boat is always producing thrust while the engines are running, some forward or reverse movement may occur.

" Do not use the reverse function to

slow down or stop the boat as it could cause you to lose control, be ejected, or impact the steering wheel or other parts of the boat. This could increase the risk of serious injury. It could also damage the shift mechanism.

" Reverse can be used to slow down

or stop during slow speed maneuvering, such as when docking. Once the engine is idling, shift to reverse and gradually increase engine speed. Make sure that there are no obstacles or people behind you before shifting into reverse.

" Keep away from the intake grates

while the engine is on. Items such as long hair, loose clothing, or PFD straps can become entangled in moving parts resulting in severe injury or drowning.

" Stop the engines and remove the

clip from the engine shut-off switch before removing any debris or weeds, which may have collected around the jet intakes.

" Never insert any object into the jet

thrust nozzle while the engine is running. Severe injury or death could result from coming in contact with the rotating parts of the jet pump.

NIGHT OPERATION

" When using your Sport Boat before

dawn or after dusk, you must have both bow and stern lights operating. When at anchor in the dark, the stern light must be lit. See page 212 for instructions.

WATER-SKIING

You can use the Sport Boat to tow a water skier, using the tow cleat provided.

It is the boat operator’s responsibility to be alert to the safety of the water-skier and others. Know and follow all state and local water-skiing regulations in effect for the w aters in which you will be operating.

The following are some important considerations for minimizing risks while water-skiing.

" The skier should wear an approved

PFD, preferably a brightly colored one so boat operators can see the skier.

" The skier should wear protective

clothing.Severe internal injuries can occur if water is forced into body cavities as a result of falling into the water or while reboarding. Normal swimwear does not adequately protect against forceful water entry into rectum or vagina. The skier should wear a wetsuit bottom or clothing that provides equivalent protection. Such clothing includes thick, tightly woven, sturdy and snug fitting

apparel such as denim, but does not include spandex or similar fabrics like those used in bicycle shorts.

" A second person should be on

board as a spotter to watch the skier; in most states it is required by law. Let the skier direct the operator’s control of speed and direction with hand signals. The port-side seat swivels for a backward-facing observer.Be sure the seat is locked in place (pg. 2-13) before getting underway.

" When preparing to pull a skier, oper-

ate the boat at the slowest possible speed until the boat is well away from the skier and slack in the towrope is taken up. Make sure that the rope is not looped around anything.

After checking that the skier is ready and that there is no traffic or other obstacles, apply enough throttle to raise the skier.

" Make smooth, wide turns.The Sport

Boat is capable of very sharp turns, which could exceed the abilities of the skier. Keep the skier at least 50m (150 ft), about twice the distance of a standard towrope, away from any potential hazard.

" Be alert to the hazard of the towrope

handle snapping back at the boat when the skier falls or is unable to get up on the skis.

RULES

OF THE R OAD

Your Yamaha Sport Boat is legally considered a powerboat. Operation of the Sport Boat must be in accordance with the rules and regulations governing the waterway on which it is used.

Just as there are rules that apply when you are driving on streets and highways, there are waterway rules that apply when you are operating 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.

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 this Owner’s/Operator’s Manual are condensed, and have been provided for your convenience only. Consult your local U.S. Coast Guard Auxiliary or Department of Motor Vehicles for a complete set of rules governing the waters in which you will be operating your boat.

STEERING AND SAILING RULES

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 rightof-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 V essel

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 briefly 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 regarding the right-of-way is that if a collision appears unavoidable, neither boat has the right-of-way. Both boats must avoid the collision.

In other words, follow the standard rules except when a collision will occur unless both vessels try to avoid each other. If that is the case, both vessels become give-way vessels.

Page 20

1 SAFETY I

NFORMATION

1-16

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 vessel head-on

Crossing: you are traveling across another 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 rightof-way to any vessels shown in the white area (you are the give-way vessel). Any vessels in the shaded area must yield to you (they are the giv e-wa y 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 does not 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 other on the starboard (right) side must keep out of the way of the other. If the other vessel is on your starboard (right) side, you must keep out of its way; you are the giveway vessel. If the other vessel is on your port (left) side, remember that you should maintain course and direction, provided the other vessel gives you the right-of-way as it should.

Page 21

SAFETY INFORMATION 1

1-17

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.

OTHER SPECIAL SITUATIONS

There are three other rules you should be aware of when operating 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 water vessels, the operator should sound a prolonged blast of four to six seconds on the horn. If another vessel is around the bend, it too should sound the horn. Even if no reply is heard, however, the vessel should still proceed around the bend with caution.

Fishing Vessel Right-of-Way

All vessels fishing with nets, lines or trawls are considered to be “fishing vessels” under the International Rules. Vessels with trolling lines are not considered fishing vessels.Fishing vessels have the right-of-way regardless of position. Fishing vessels cannot, 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 rightof-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 navigating in a particular direction. The mar kings on these buoys are oriented from the perspective of being entered from seaward (the boater is going towards the harbor). Red buoys are passed on your starboard (right) side when proceeding from open water into port, and black buoys are to your port (left) side. An easy way to remember the meaning of the colors is the phrase “red right returning.” When navigating out of the harbor, y our 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 distinctive shapes and colors to show regulatory or advisory information. These markers are white with black letters and orange borders. They signify speed zones, restricted areas, danger areas, and general information.

Remember, markings may v ary by geographic location. Always consult local boating authorities before riding your boat in unfamiliar waters.

ACCIDENT

REPORTING

Boat operators are required by law to file a Boating Accident Report with their state boating law enforcement agency if their boat is involved in any of the following accidents:

1. There is loss of life or probable loss of life.

2. The is personal injury which requires medical attention beyond first aid.

3. There is damage to boats or other property which exceeds $500.00.

4. There is complete loss of a boat. Contact local law enforcement per-

sonnel if a report is necessar y.

ENJO Y YOUR SPORT BOAT RESPONSIBLY

You share the areas you enjoy when operating your boat with others and with nature. So your enjoyment includes a responsibility to treat these other people, and the lands, waters, and wildlife with respect and courtesy.

Whenever and wherever you are boating, think of yourself as the guest of those around you. Remember, for example, that the sound of your boat may be music to you, but it could be just noise to others. And the exciting splash of your wake can make waves others won't enjoy. Avoid riding close to shoreline homes and waterfowl nesting areas or other wildlife areas, and keep a respectful distance from fishermen, other boats, swimmers, and populated beaches. When travel in areas like these is unavoidable, operate slowly and obey all laws.

Remember that pollution can be harmful to the environment. Do not refuel or add oil where a spill could cause damage to nature.And keep your surroundings pleasant for the people and wildlife that share the waterways:don't litter!

When you go boating responsibly, with respect and courtesy for others, you help ensure that our waterways stay open for the enjoyment of a var iety of recreational opportunities.

OPERATION OF

CONTROLS AND

OTHER FUNCTIONS

STEERING

➀ Steer ing wheel

Your Sport Boat can be steered by turning the steering wheel the same direction you wish to travel, to the right or left. When the wheel is turned, the angle of the jet (output) nozzles at the rear of the craft is changed, and the change in direction of the nozzles changes the direction of the boat accordingly. Since the strength of the jet thrust determines the speed and direction of a turn, the throttle must always be opened above idle when attempting a turn, except at trolling speed.

Because boats steer from the stern (rear), the stern of the boat swings out in the opposite direction of your turn. If you turn to the starboard (right), for example, the stern of the boat will swing to the left. Keep this in mind when navigating near a person in the water, such as a down skier, or an obstacle, such as a dock.

ENGINE SHUT-OFF SWITCH

The clip on the end of the engine shutoff cord must be attached to the engine shut-off switch for the engines to run. The cord must be attached to a secure place on the operator’s personal flotation device (PFD). Should the operator fall overboard or leave the helm, the cord will pull out the clip, stopping ignition to both engines. This will prevent the boat from running away under power.

➀ Engine shut-off switch ➁ Clip ➂ Engine shut-off cord (lanyard)

FEATURES & FUNCTIONS 2

Page 32

2-6

" Always attach the engine shut-off

cord to your personal flotation device (PFD) BEFORE starting the engine. Failure to attach the cord could result in a runaway boat if the operator is ejected.

" Do not attach the cord to clothing

that could tear loose. Do not route the cord in such a way that it could become entangled, preventing it from functioning.

" Avoid accidentally pulling the

cord during normal operation. Once the engine has stopped you have no steering control of the boat which could result in an accident. Also, without engine power, the boat could slow rapidly from planing speed. This could cause people and objects in the boat to be thrown forward, which could cause injury.

MAIN SWITCHES

There is a main switch for each engine . The main switches control the ignition and electrical circuits as follows:

1 Port (left) engine 2 Starboard (right) engine

OFF:

Ignition circuits are switched off. The engine cannot be started but other switches will operate. (The key can be removed.)

ON:

Ignition circuits are switched on. (The key cannot be removed).

START:

The starter motor will turn to star t the engine. (When the key is released, it returns automatically to “ON.”)

NOTE: The engine will not start when the engine shut-off cord clip is removed from the engine stop switch.The starter motor will turn over without the cord attached.

THROTTLE LEVERS

1 Throttle lever, port (left) engine 2 Throttle lev er, starboard (right) engine 3 Idle 4 Full speed

Before starting the engine, always check the operation of each throttle lever. It should move smoothly through its full range of operation. Otherwise, there could be loss of control and an accident.

2 FEATURES

& FUNCTIONS

WARNING

Page 33

2-7

A separate throttle lever controls each engine. In normal operation the throttle levers are moved together. Moving the throttle levers forward increases engine speed. Move both throttles to the idle position before using the shift lever.

SHIFT LEVER

SEVERE INJURY OR DEATH MAY RESULT IF YOU IGNORE ANY OF THE FOLLOWING.

" Check throttle, steering, and shift

lever for proper operation before starting the engines.

" Shift into neutral before starting

engines.

" Put throttle levers in idle position

before shifting.

" Make sure there are no people or

objects behind the boat before starting or shifting into Reverse.

" When operating in Reverse, go

slowly. Do not open the throttle more than half. Otherwise, the boat may become unstable, which could result in loss of control and an accident.

" Do not shift into Reverse while

traveling at planing speeds. Loss of control, boat swamping, or damage to the boat could occur.

Do not use control levers as grab handles because damage can occur.

NOTE: This Sport Boat is equipped

with a mechanical interlock that prevents shift lever movement unless both throttle levers are put in the idle position

first. It also has a star t-in-gear protection neutral switch that prevents the engines from cranking if the shift lever is not in Neutral.

1 Reverse 2 Neutral 3 Forward

The shift lever controls the direction of travel.

The drive line on the Sport Boat is direct drive, so jet thrust is always being produced while the engines are running. The direction of the boat is controlled by jet pump gates which direct the flow of the jet thrust as follows:

Forward

The jet pump gates are lifted all the way up. All jet thrust is to the rear, which moves the boat forward.

FEATURES & FUNCTIONS 2

WARNING

CAUTION:

Page 34

2-8

Neutral

The jet pump gates are dropped down part way over the jet nozzles.Some jet thrust is to the rear and some jet thrust is redirected forward. This balance of thrust acts like “neutral” to keep the boat from moving.

Leave the throttles in the idle position when Neutral is selected. The boat will start moving as if it was in Forward or Reverse if engine speed is increased above idle in Neutral.

Reverse

The jet pump gates are dropped all the way down ov er the jet nozzles .Jet thrust is redirected toward the bow of the boat, which moves the boat backward.

Choke Knobs

➀ Choke knob (Starboard) ➁ Choke knob (Port)

Pulling these knobs supplies a rich fuel-air mixture required to start the engines.

NOTE: Refer to Starting The Engines on pages 3-13 to 3-15 for proper operation.

FUEL TANK FILLER CAP

To remov e the fuel tank filler cap, turn it counterclockwise.

➀ Fuel tank filler cap ➁ Fuel tank vent

Be sure to tighten the cap securely before operating.

GAUGES

1. Speedometer

This meter shows the boat speed in miles per hour (mph).

2. Tachometer s

The Sport Boat has two tachometers which display engine rpm. The one on the left is for the port engine. The one on the right is for the starboard engine. For cruising, adjust the throttle levers so both engines are running at the same rpm.

NOTE: Because of the mechanical throttle linkage, the throttle levers may not be exactly even with one another when the engines are running at the same rpm.

3. Fuel Level Gauge

The fuel level gauge shows the amount of fuel in the fuel tank. The ignition switch must be in the “ON” position to activate the gauge.

Always consider the distance you are travelling and the amount of available fuel you have. Be sure you have enough fuel to reach the next fuel stop. Be sure to begin returning to the port before you have consumed a half a tank of fuel.

4. Warning Indicators

The warning indicator panel has lights to alert you about certain conditions on your Sport Boat.

Low Oil - If the oil tank is too low to continue normal operation for much longer , this warning light 2 will come on. Refill the oil tank as soon as possible (see “Filling the Oil Tank,” page 3-3).

If the oil level warning indicator comes on, refill with engine oil as soon as possible. The engines will be severely damaged if they are run without oil.

OVERHEAT WARNING SYSTEM

The engine has an overheat warning device. If either engine star ts to overheat, the engine speed of the affected engine will be limited to about 3,500 rpm.

Each engine is equipped with coolingwater pilot outlets on the starboard side of the hull. Check that water comes out of the outlet while the engine is running, particularly while applying throttle. If you do not see any water at the outlet, cooling water may not be circulating in the engine.

NOTE: If water cooling passages on the engines are dry , it will take about 20 seconds for water to reach the pilot outlets after starting.

FUEL AND OIL

GASOLINE

Use regular unleaded 87 octane (R+M ÷ 2) gasoline.

GASOLINE AND ITS VAPORS ARE HIGHLY FLAMMABLE AND EXPLOSIVE!

Do not smoke when refueling, and keep away from sparks, flames, or other sources of ignition.

Stop engines and turn ignition keys to Off before refueling.

Refuel in a well-ventilated area. If the Sport Boat is in the water, be sure it is securely moored to the fueling dock. All passengers must be out of the boat during refueling.

Take care not to spill gasoline . If gasoline spills, wipe it up immediately with dry rags. Always properly dispose of gasolinesoaked rags.

Avoid overfilling the fuel tank. Stop filling when the fuel level just reaches the bottom of the filler tube. Do not fill up the filler tube because fuel expands as it warms up and could overflow.

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.

Use only fresh gasoline that has been stored in clean containers.

Gasohol

There are two types of gasohol: gasohol containing ethanol and that containing methanol. Gasohol containing ethanol can be used if ethanol content does not exceed 10% and the fuel meets minimum octane ratings. Gasohol containing methanol is not recommended by Yamaha because it can cause fuel system damage or engine performance problems.

Ring Free Fuel Additive

Gasoline is a precise blend of many different substances, each chosen to giv e certain characteristics. Gasoline blends have been changing in recent years in response to concerns about pollution and resulting emissions regulations. One of the most obvious changes has been the elimination of lead from fuels.

As gasoline has changed, the amount of additives such as aromatics and oxygenates has increased. These additives are important for the engines in passenger cars, but they can have detrimental effects in marine engines, particularly 2-stroke engines, because

WARNING

CAUTION:

Page 45

3-2

of increased deposits in the combustion chamber. When enough deposits collect, piston rings begin sticking. Performance drops and engine wear increases dramatically.

While many additives available may reduce deposits, Yamaha recommends the use of Ring Free Fuel Additive, available from your Yamaha dealer. Ring Free has repeatedly proven its ability to clean combustion deposits from inside the engine, notably in the critical piston-ring-land area, and fuel system components. Follow product labeling for use instructions.

ENGINE OIL

Recommended oil: YAMALUBE 2-W. If YAMALUBE 2-W is not available, another 2-cycle engine oil with a NMMA®-certified TC-W3™rating may be used.

OIL INJECTION

SYSTEM

These engines use Yamaha's oil injection system, which provides superior lubrication by ensuring the proper oil ratio for all operating conditions. No fuel premixing is necessary (except during break-in). Simply pour gasoline into the fuel tank and oil into the oil tank.

Do not allow the oil tank to empty completely. The oil injection pump must be bled to ensure proper oil flow after the tank empties. Otherwise, engine damage may occur. Refer to page 4-13, “Bleeding the Oil Injection Pump,” for correct procedure.

FILLING

FILLING THE GASOLINE TANK

Open the fuel tank filler cap, and slowly add fuel to the fuel tank. Be careful not to spill fuel or overfill the tank.

Stop filling when the fuel just becomes visible in the bottom of the filler tube. Do not “top off” the tank, because gasoline could spill out. Be sure to tighten the cap securely.

Be careful when refueling. Avoid getting water or other contaminants in the fuel tank. Contaminated fuel can cause poor running or engine damage.

Fuel tank capacity: 41 US gal (155.2 lit)

FILLING THE OIL TANK

Open the engine hood, then open the oil tank filler cap. Very slowly add engine oil to the oil tank. Stop pouring when the oil just reaches the bottom of the filler neck. Be sure to tighten the cap securely.

● Oil in the bilge is a serious fire

hazard. Wipe up any spilled oil immediately and properly dispose oil soaked rags.

● Do not add gasoline to the oil

tank. Fire or explosion could result.

Oil tank capacity: 3.0 US gal (11.4 lit)

NOTE: Pre-operation checks should be made each time the boat is used. This procedure can be accomplished thoroughly in a short time.The added safety and reliability the checks assure is worth the time involved.

CHECK POINTS

Steering

Make sure the wheel is not loose.There should not be any free play, either inand-out or in rotation.Turn the steering wheel full-right and full-left to make sure operation is smooth and unrestricted throughout the whole range.

Make sure both jet nozzles change directions as the steering wheel is turned. The jet nozzles should point to starboard (right) when the wheel is turned right. The jet nozzles should point to port (left) when the wheel is turned left. There should not be free play between the steering wheel and the jet nozzles.

Throttle

Operate the throttle levers several times to make sure there is no hesitation in their travel.Operation should be smooth over the complete range of motion, and each lever should return completely to the idle position.

Shifting

Before launching, make sure both jet pump gates drop down over the jet nozzles to their stopper positions when the shift lever is moved to the “Reverse” position. Also make sure both jet pump gates return to the full up stopper position when the shift lever is mo v ed to the “Forward” position.

Shift only with the engine idling. Do not shift when applying throttle.

Fire Extinguisher

Make sure the fire extinguisher is aboard and full. See the instructions supplied by the fire extinguisher manufacturer to determine proper indication of condition.

The fire extinguisher canister is located inside the driver-side console storage compartment. Open the windshield cover, and then unscrew the canister to reach the fire extinguisher.

Always carry a fire extinguisher on board.

This Sport Boat is an inboard boat less than 26’ long. A boat of this type MUST carry a fire extinguisher of a B-1 classification, with a capacity of two pounds or more, when navigating in waters controlled by the U.S. Coast Guard. In addition, most state and local boating laws also require that the craft carry a USCG-approved fire extinguisher whenever the boat is operated.

A fire extinguisher is not standard equipment with this boat. If you do not have one, contact your local Yamaha Sport Boat dealer or a fire extinguisher dealer to obtain one meeting the proper specifications.

Access Port Caps

Lift the hatch on the rear platform. Pull up forcefully on the T-handle of each cap. If the cap will move, it is not installed properly. Refer to “Jet Pump Clean-Out Procedure” on page 5-5 for proper installation instructions.

Jet Intakes

Before launching the Sport Boat, carefully check the jet intakes under the boat for weeds, debris, or an ything else that might restrict the intake of water. If the intakes are clogged, cavitation could occur, reducing jet thrust, and possibly damaging jet pump parts. In some cases, the engine may overheat because of lack of cooling water, and damage could result. Engine cooling water is fed to the engine by the jet pumps (see pages 2-10).

Refer to Jet Pump Clean-Out procedures on page 5-5 before attempting to remove weeds or debris from the jet intake or impeller areas.

Rotating parts could cause severe injury or death. Before attempting to remove weeds or debris from the jet intake or impeller areas; shut off the engines, remove ignition key, then remove the engine shut-off switch cord from the shut-off switch.

Fuel System

Refer to page 4-11, “FUEL SYSTEM INSPECTION,” for correct procedure.

Fuel and Engine Oil Levels

1) Turn the main switch key to ON.Wait for the fuel gauge needle to stop moving, then note the fuel lev el.Add fuel if necessary.

NOTE: The fuel level is most accurate when the boat is sitting level on the trailer or in the water.

2) Open the engine hatch, remove the center storage tray, then check oil level in the tank.Add as necessary.

Battery

The Sport Boat uses one battery. Check the battery condition and the battery electrolyte level. Make sure connections are tight and that battery is properly secured.

The battery must always be fully charged and in good condition.Loss of battery power may leave you stranded. Never operate the Sport Boat if the battery does not have sufficient power to start the engine or if it shows any other signs of decreased power.

Drainage System

through the large drain hole in the deck. A one-way check valve in the drain prevents water from traveling back to the deck during mooring or while moving in reverse.

Bilge Pump –

Your Sport Boat is equipped with a drainage system that channels water that enters the boat from the storage compartments to the bilge under the engine compartment. When the bilge pump is turned on (see page 2-11), the pump will sense when there is excessive water in the bilge and will automatically drain most of it. For normal operation, turn the bilge pump switch on during boat use and turn it off when leaving the boat.

If the Sport Boat is to be left in the water after use, leave the bilge pump switch in the ON position.The pump will activate if needed to drain any water which accumulates in the bilge.

Drain Plug –

A drain plug is located at the center of the stern to allow more complete draining when the boat is removed from the water.

Engine Compartment and Fuel Compartment Drain Plug –

Water will not normally enter the engine compartment or fuel compartment areas during operation. If it does, open the drain plugs and allow water to drain. Also open the engine compartment plug when flushing the engine area with fresh water after salt water operation.

● Excessive water in the engine

compartment bilge can splash into the carburetor and engine. This could cause engine damage.

● Be sure all drain plugs are tight-

ened before operating your Sport Boat.

Gasoline and its vapors are highly flammable and explosive. If a fuel or a fuel/water mix drains from the fuel tank compartment drain or is found in the engine compartment, wipe it up immediately with dry rags. Do not operate the boat until the source of the fuel leak is found and corrected.

ST ARTING THE ENGINES

SEVERE INJURY OR DEATH MAY RESULT IF YOU IGNORE ANY OF THE FOLLOWING:

Before operating your Sport Boat, become familiar with all controls. Consult your Yamaha dealer about any control or function you do not fully understand.

Attach the engine shut-off switch cord to your personal flotation device before operating. Failure to attach cord could result in a runaway boat if operator is ejected.

Check throttle, steering and shift lever for proper operation before starting the engine.

Shift into Neutral before starting engines. Put throttle levers in idle position before shifting.

Never start the engine or let it run any length of time in an enclosed area. Exhaust fumes contain carbon monoxide, a colorless, odorless gas that may cause loss of consciousness and death within a short time. Always operate the boat in an open area.

1) Always make sure the boat is launched and used in waters that are free from weeds and debris, and at least 3 ft (90 cm) deep.

Never operate in water that is less than 3 ft (90 cm) deep.You increase your chance of hitting an underwater obstacle. You could be injured. Pebbles or sand can also be sucked into the jet (water) intake, damaging the impeller.

There is a hull drain plug at the bottom of the stern in the center. Be sure it is securely tightened before launching the Sport Boat.

4) Put the throttle levers in the idle position. Shift into Neutral. Tur n the ignition key of one engine to “Start.” When the engine starts, release the key. Repeat for the other engine. If the engine will not start or doesn’t stay running, move the throttle levers forward slightly and tr y again.

Never turn the ignition key to “Start” while the engine is running. Do not keep the starter motor running for more than 5 seconds. If the engine does not start after 5 seconds of cranking, release the starter button. Wait at least 15 seconds before trying to start the engine again. If the starter motor is engaged continuously for more than 5 seconds, the battery will be quickly discharged, and it will be impossible to start the engine. The starter motor may also be damaged if it is engaged continuously for more than 5 seconds.

NOTE:

" Be sure the shift lever is put in the

Neutral position or the starter motor will not operate.

" On this boat, the engines are con-

nected directly to the drive unit. Starting either engine generates some thrust immediately. Only enough throttle should be applied to keep the engine at a fast enough idle to stay running.

5) After the engines are warm, gradually push the choke knobs in fully, back to their original position.

Do not operate the Sport Boat with just one engine running. Severe engine damage could result because water can flood the nonoperating engine through the cooling water intake. If single-engine operation is unavoidable, operate the boat at a “no wake” speed only.

PERATION 3

CAUTION:

Page 59

3-16

STOPPING THE ENGINES

To stop the engine, return the throttle levers to the idle position, then turn the main switches to “Off.”The engines can also be stopped by pulling the engine stop switch lanyard.

Once the engine has stopped, you have NO STEERING CONTROL over the boat. You could collide with another boat, a dock, or other obstacle.

NOTE:

" Remove the ignition keys and the

engine stop switch lanyard if the boat will be left unattended.

" Stopping the engines immediately

after operating at high rpm is not recommended. Let the engines cool off at idle or low speed for a few minutes first.

BREAK-IN PROCEDURE

The engine and other components require a break-in period to allow surfaces of moving parts to wear in evenly. This ensures proper performance and promotes longer engine life.

" Failure to follow the break-in pro-

cedures may result in reduced engine life, or even engine damage.

" During first full tank of fuel, use

50:1 pre-mix fuel (in addition to oil in oil tank).

" After above period, use straight

gasoline for normal operation.

1) Before launching: Fill the fuel tank with 50:1 premix fuel.Fill the oil tank with oil (see page 3-3). Launch the boat and start the engine (see page 3-13).

2) First 5 minutes: Run the engine at the lowest possible idling speed.

3) First tank of fuel:Gradually increase the throttle position during operation, up to a maximum of one-half throttle. Vary engine speed occasionally.

4) Following this tank of premix fuel, use straight gasoline in the fuel tank and oil in the oil tank (see page 3-3). Proceed with normal operation.

DRIVING Y OUR

SPORT BOAT

GETTING TO KNOW Y OUR SPORT BOAT

Operating your Sport Boat requires skills acquired through practice over a period of time. Take the time to learn the basic techniques well before attempting more difficult maneuvers.

Boating with your new Sport Boat can be a very enjoyable activity, providing you with hours of pleasure. But it is essential to familiarize yourself with the operation of the Sport Boat to achieve the skill necessary to enjoy boating safely.Before operating this Sport Boat, read this Owner’s Manual, the Operation Instruction Card, and all Warning and Caution labels on the boat. Pay particular attention to the safety information in Chapter 1. Read all warning and caution labels on your Sport Boat.

This Sport Boat is designed to carry one operator and up to six passengers, as long as the total weight of people and cargo does not exceed 1300 lb (591 kg). Never have more than seven people in the boat.

LEARNING TO OPERATE Y OUR SPORT BOAT

Before boating, always perform the Pre-Operation Checks listed on page 3-4. The shor t time spent checking the machine's condition will reward you with added safety and a more reliable Sport Boat.

Know and follow U.S. Coast Guard, state, and local laws when operating your Sport Boat.

Select a wide area to learn in, where visibility is good and other boat traffic is light. Keep the proper distance from other boats and vehicles. Do not operate where people are swimming.

Always attach the engine stop switch lanyard to your personal flotation device before operating.

You and all other passengers must always wear a U.S. Coast Guardapproved personal flotation device when riding in the Sport Boat. You should consider wearing water shoes, eye protection, gloves, and other protective apparel. Water sports increase your risk of injury from contact with your boat, other vessels, docks, rocks, or coral.

A water-skier should wear protective clothing. Severe internal injuries can occur if water is forced into body cavities as a result of falling into the water or while reboarding. Normal swimwear does not adequately protect against forceful water entry into rectum or vagina.The skier should wear a wetsuit bottom or clothing that provides equivalent protection.Such clothing includes thick, tightly woven, sturdy and snug fitting apparel such as denim, but does not include spandex or similar fabrics like those used in bicycle shorts.

Grip the wheel firmly and keep both feet on the deck when driving the Sport Boat.

PERATION 3

Page 61

3-18

TURNING THE SPORT BOAT

Steering control depends on the combination of steering wheel position and the amount of throttle.

Water sucked in through the intake grate is pressurized by the impeller in the jet pump. As the pressurized water is expelled from the pump through the jet thrust nozzle, it creates thrust to move and steer the Sport Boat. The higher the engine speed, the more thrust is produced.

The amount of jet thrust, in addition to the position of the steering wheel, determines how sharply you turn.

A. More throttle produces high thrust,

so the Sport Boat will turn more sharply.

B. Less throttle produces low thrust, so

the Sport Boat will turn more gradually.

C. Pulling the throttle levers complete-

ly back to idle produces only minimum thrust. If you are traveling at speeds above trolling, you will have rapidly decreasing ability to steer without throttle. You may still have some turning ability immediately after pulling the throttle levers back to idle, but once the engine slows down, the Sport Boat will no longer respond to steering wheel input until you apply throttle again or you reach a trolling speed.

At trolling speed, the Sport Boat can be turned gradually by steering wheel position alone using just the amount of thrust available at engine idle.

D. If the engines are stopped, there is

no thrust. The Sport Boat will go straight even though the steering wheel is turned.

YOU NEED THROTTLE T O STEER.

" Do not pull the throttle levers

back to idle when trying to steer away from objects – you need throttle to steer.

" Be sure passengers are holding

on before making turns. An unprepared passenger could lose balance and fall.

BOATING WITH PASSENGERS

When one or more passengers are on board, the boat may handle differently, so operating it requires a higher degree of skill.

Remember: Your Sport Boat is designed for one operator and up to six passengers only .Never have more than seven people in the Sport Boat. Passengers should sit so the weight in the boat is balanced from side-to-side and bow-to-stern as much as possible. If the passenger seat in front of the helm is used, be sure the operator’s view ahead is not obstructed.

Passengers must sit in one of the seats and hold onto the grips while putting both feet on the deck.

When passengers are on board, make sure they are seated and holding on before you start to accelerate. An unprepared passenger could lose balance and fall.

BOARDING FROM THE WATER

Severe internal injuries can occur if water is forced into body ca vities as a result of being near the jet thrust nozzles.

" Do not board from the rear, use

swim platform, or swim behind boat if engines are running.

" Stay away from the back of the

boat when engines are running.

CAUTION:

Page 64

3-21

STOPPING

The Sport Boat is not equipped with a separate braking system. It is stopped by water resistance after the throttle levers are moved back to idle.From full speed, the Sport Boat stops in approximately 400 ft (122 m) after the throttle is moved back to idle .The stopping distance varies depending on gross weight, water surface conditions, and wind direction. The stated straightlinestopping distance should be used for a reference .The boat slows down as soon as the throttle levers are returned to idle but will coast for a distance before fully stopping.If you are not sure you can stop in time before hitting an obstacle, apply throttle and turn in another direction.

You will lose steering control if you completely pull the throttle levers back to idle.

DOCKING

1) Make sure no obstructions, boats or swimmers are close to the Sport Boat. Come to a stop before you reach the dock.

2) Notice how wind and water currents are affecting boat movement as you attach your mooring lines and fenders.

3) Approach the dock at idle speed. Use reverse as necessary during slow speed maneuvering to help control speed and direction.Position the boat according to wind and water conditions.

Do not use your hand, arm, or other part of your body to try to keep the boat from hitting the dock.You could be injured if the boat pushes against the dock.

Wind or current pushing boat away from dock:

Slowly approach the dock at about a 45° angle. Secure the bow to the dock, then use engine thrust or a boat hook to gently move the stern to the dock.

Wind or current pushing boat toward dock:

Slowly maneuver to a shallow angle and allow the boat to move toward the dock.

No wind or current:

Approach the dock at a shallow angle. Secure the bow to the dock, then use engine thrust or a boat hook to gently move the stern to the dock.

LEAVING A DOCK

Because boats steer from the stern, the stern first moves in the direction opposite your desired turn. It is especially important to understand this characteristic when leaving a dock. If you simply turn the wheel to steer the bow away from the dock, as you would when driving a car out of a parking space, you will drive the stern of the boat into the dock. Following is a basic maneuvering technique which can be used in most circumstances.

1) With engines idling and the bow still moored to the dock turn the steering wheel toward the dock. This will start to move the stern of the boat away from the dock.

2) When the stern is out a few feet, release the bow mooring then steer in the direction you want the bow to move. Open the throttle slightly and begin to move away from the dock.

BEACHING

1) Make sure no obstructions, boats or swimmers are near the beach.

2) Approach the beach slowly and stop the engines when the water is about 3 ft (90 cm) deep. Remember: tur ning is impossible with the engine stopped.

3) Get out of the boat and pull the bow up on the beach.

4) When leaving the beach, push the boat out into water that is at least 3 ft (90 cm) deep before starting the engines.

● Small pebbles, sand, seaweed, and other debris can be ingested into the jet intake and impair or damage the impeller.Always stop the engines before beaching the boat. Be sure the boat is in water 3 ft (90 cm) deep before starting the engines again.

● Do not beach the boat on rocky beaches. The hull gelcoat and exposed pump housings can be damaged.

● Pay attention to shifts in tides. Beaching at high tide may make it impossible to re-launch the boat if the tide recedes.

3 OPERATION

WIND OR CURRENT

CAUTION:

Page 66

ANCHORING

Always anchor from the bow. Anchoring from the stern will make the boat unsteady. A strong current can pull a stern-anchored boat underwater.

Select an anchor appropriate for your boat and water conditions. A “danforth” (or fluke) type anchor is suitable for most applications; your dealer can help you choose an anchor.

1) Make sure the anchor line is securely tied to the anchor and to the bow eye.

2) Move the boat to the spot where y ou want to lower the anchor, heading the boat into the wind or current. Stop the boat, then lower the anchor until it hits bottom.

3) While keeping tension on the line, slowly back up the boat until you have let out line that is 4 to 6 times the depth of the water.For example, if you are anchoring in 10 feet of water, let out 40 to 60 feet of line. Secure the line.

4) Pull on the line to be sure the anchor is holding. Also, periodically check your boat's position against the shoreline to make sure it is not drifting and dragging the anchor. Reset it if necessary.

5) To pull in (“weigh”) the anchor, start the engines and move forward, keeping tension on the line as you pull it in. When the anchor line is straight up and down, pull hard to lift the anchor from the bottom material.

6) If the anchor is stuck on the bottom, try this: Let out a few feet of anchor line and secure the line to the boat again. Slowly maneuver the boat around the anchor until the anchor pulls loose.Keep the line taut during this procedure.

CROSSING WAKES AND SWELLS

You will not always have flat, smooth water.There will be swells, wakes from other boats, etc.

The best way to cross wakes and swells is with the least jolt to you and the boat. Small swells are not as difficult to cross as larger swells or wakes. Crossing a sharp wake gives more of a jolt than a broad swell.

To cross a wake or swell, change your speed and choose the angle at which you cross the wake or swell. Usually, a slower speed and “quartering” the wake (crossing at an angle) will reduce the jolt.

Two other things you may notice. The first is that crossing a group of wakes or swells is not as easy or smooth as crossing just one wake.The second is that when you quarter the wake or swell the boat will try to steer away from the wake or swell. When crossing at a 45° angle, you may not notice this, but at a smaller angle, say10°, it can be very strong. Be prepared to steer and balance as necessary.

POST-OPERATION

CHECKS

POST-OPERATION CHECKS

These post-operation procedures are developed to help preserve the longterm appearance and reliability of your Sport Boat. Perfor m these procedures as soon as possible after the boat is loaded back on the trailer after the day’s use.

Some owners plan to moor their boat seasonally, rather than keeping it on the trailer between uses. The procedures described in this section may not be possible if your Sport Boat is moored in the water. Boats which are moored will require periodic removal from the water to clean the hull and jet pump area.The frequency of this maintenance will depend upon whether the water is salt or fresh, as well as other local water conditions.

Leaving the boat in the water for extended periods will accelerate the rate of normal deterioration of the jet pump components and hull finish. Stray electrical voltage in the water, marine organisms, and saltwater corrosion are a few of the conditions that can adversely affect the life of many Sport Boat components.

1) After putting the Sport Boat on the trailer, flush cooling system on each engine to prevent the cooling system from clogging up with salt, sand, or dirt. Refer to page 4-2 for the cooling system flushing procedure.

2) Drain residual water from the exhaust system by starting the engine then alternately pushing the throttle lever up to half throttle and back for 10 to 15 seconds.

Never run the engine at full throttle or for more than 15 seconds while the boat is out of the water. The engine may overheat and/or seize.

3) Wash down the hull, helm, and both jet drive units with fresh water.

4) Open the rear platform hatch, and check for any w ater pooled on top of the clean-out port caps. If water is found, remove the caps, let water drain, then reinstall the caps. See Page 5-5 for more information.

PERATION 3

CAUTION:

Page 69

5) Remove hull drain plug and the engine compartment drain plugs. Rinse the engine compartment with a small amount of fresh water. Be careful not to get water on the carburetor or electrical components. Allow any water in the bilge to drain out. After the water has drained, wipe the engine compartment and bilge with dry rags.Reinstall all drain plugs.

NOTE: This boat is equipped with an electric bilge pump that automatically removes excess water from the bilge while you are underway. However, some residual water remains that must be drained by removing the drain plug.

Tighten the hull drain plug securely before launching the Sport Boat. Clean any foreign material, such as dirt or sand, from the threads before installing the drain plug.

6) Spray a rust inhibitor, such as Yamaha Silicone Protectant and Lubricant, on metallic parts to minimize corrosion.

TRAILERING

Avoid accident and injury from improper trailering:

" The trailer must be matched for

the Sport Boat’s weight and hull.

" The towing vehicle must have the

capacity of pulling the load. Pulling a load that exceeds the towing capacity may cause loss of control.

" Be sure the boat is secured to the

trailer and the trailer is properly hitched to the towing vehicle before towing.

A trailer is provided as standard equipment with your Sport Boat. If you need to obtain another trailer, choose one that is manufactured to carry a boat of the size and weight of your Sport Boat. Check the certification label on the left forward side of the trailer. This label is required to show the Gross Vehicle Weight Rating (GVWR), which is the load carrying capacity of the trailer plus the trailer’s weight. Be sure that the total weight of your boat, any cargo, and the trailer weight itself does not exceed the GVWR.

HITCH

The trailer hitch ball must match the size of the socket on the trailer hitch coupler.Hitches are divided into classes that specify the gross trailer weight (GTW) and the maximum tongue weight.Always use a hitch rated for the same or higher class. Use a bolted-on or welded-on hitch; clamp-on bumper hitches are not recommended. Be sure the trailer hitch’s release handle is latched with the lock pin installed before towing.

Use safety chains between the towing vehicle and the trailer so the trailer will not detach completely from the towing vehicle if it accidentally comes loose from the hitch ball. Crisscross the chains under the trailer tongue so the tongue will not hit the road surface if it falls loose. Rig the chains as tightly as possible while allowing just enough slack to permit tight turns.

Be sure the tongue weight (vertical weight on the hitch point) is correct. Generally, 5% to 10% of the combined weight of the boat and trailer should be on the tongue. Too much or too little weight can cause difficult steering or trailer swaying.

TRAILERING CHECKLIST

" Check your state laws to be sure

your trailer meets all regulations, such as proper licensing, brake, axle load, and safety chain requirements.

" Check trailer for any loose f asteners

or damaged parts.

" Check tires for proper inflation.

OPERATION 3

WARNING

Page 71

3-28

" Check wheel bearings and wheel

lug nuts before each trip.

" Check tail, brake, and turn signal

lights for proper operation.

" Secure the bow of the boat to the

trailer with the winch line and also with a separate bow tie-down to the winch stand and frame crossmember. Secure the stern cleats to the trailer with tie-downs.

" Take down and store the bimini top,

if used. The top is not designed to stay unsecured on the Sport Boat at highway speeds.See page 3-12.

" Carry a spare tire for the trailer,

along with sufficient tools to change the tire.

" While traveling, check the wheel

hubs on the trailer whenever you park.If the hub feels abnormally hot, have the bearing inspected before

continuing your trip. On longer trips, it is a good idea to carry a set of spare wheel bearings, seals, and races.

" When making a turn, do not cut cor-

ners. The trailer has a smaller turning circle so it turns more sharply around the corner than the towing vehicle.

" Before backing your trailer into the

water, disconnect the light plug from the towing vehicle. This will reduce the likelihood of the lights blowing out when submerged.

BACKING Y OUR TRAILER

It takes practice to back a trailer successfully. If you are not familiar backing up with a trailer, pr actice first in an open area away from obstacles.

Keep the following points in mind: " Back slowly. Make steering adjust-

ments in small steps.

OPERATION 3

LAUNCHING

As a courtesy to other boaters, prepare your Sport Boat for launching before using the ramp.

Each launch may hav e particular differences, such as ramp angle, prevailing wind, waves, and water currents. If possible, watch a couple of boaters launch their boats first to notice any problems.While every boater develops a preferred launch procedure, here is a recommended general procedure:

1) Perform the Pre-Operation Checks shown on page 3-4 that can be performed on land, including operating the blower for at least 4 minutes.

2) Remove all trailering tie-down lines from the boat and attach your docking lines and fenders, if used.

3) Disconnect the trailer lights from the towing vehicle.

4) Back the trailer down the ramp as close to 90° to the shoreline as you can. If possible, have a second person stand aside as an observer. Stop when the wheels are at least halfway submerged.Set the parking brake.

5) Remove the bow line from the bow eye.

6) Back the trailer f arther into the water until just the tops of the fenders show, then reset the par king brake. Board the boat and start it. If possible, remain on the trailer until the engines are warm and are responding to throttle.

7) Back the boat out into the water, watching carefully for people, other boats, or obstacles.

1) Disconnect the trailer lights from the towing vehicle.

2) Back the trailer down the ramp as close to 90° to the shoreline as you can. If possible, have a second person act as an observer while standing to the side of the boat. Stop when the tops of the trailer’s f enders are about 3 inches above the waterline.

3) With the boat moving at the slowest idle speed, guide the boat onto the support rails. Use throttle only if necessary for steering ability.

Using too much throttle can cause the boat to jump over the front of the trailer which can result in injury to the boat operator and bystanders. Use only enough throttle to maneuver the boat into the correct position.

WARNING

Page 73

4) Make sure the boat is centered on the support rails and is headed straight for the bow stop (bumper board). Ease the boat forward until the bow rests against the bow stop.

5) Attach and tighten the winch line.

" The winch line is not designed to

pull the boat onto the trailer.

" The winch line should not be the

only line securing the bow during trailering. Use a separate bow tiedown line along with the winch to secure the boat to the trailer.

6) Pull the trailer up the ramp out of the way of other boaters.Attach the bo w and stern tie-downs. Reconnect the trailer lights.

7) Follow the Post-Operation Checks on page 3-25.

LIFTING

Do not attach lifting cables to the bow eye, cleats, water-ski tow eye, or grab handles. Serious damage to the boat can occur. Use only a sling designed specifically for lifting boats.

If you need to remove the Sport Boat from the water without a trailer, use these guidelines:

" Use a sling-type lifting mechanism

designed for lifting boats. The sling should be covered with a protective material to prevent damage to the hull gelcoat.

" Use spreader bars to avoid side

stress to the hull that may cause cracks in the gelcoat and fiberglass.

" Attach guidelines to the bow eye

and stern tie-down cleats to control movement of the boat during lifting.

" Remove all people and all cargo

from the boat. Drain any excess water from the bilge using the bilge pump.

" Be sure all people are standing

clear, then lift boat slowly and just far enough to verify that the boat is securely held and properly balanced. If necessar y, lower the boat again and adjust the slings.

" When ready, lift the boat slowly and

carefully.

STORAGE

Storing your Sport Boat for prolonged periods of time, such as winter storage, requires preventative maintenance to ensure against deterioration.It is advisable to have the Sport Boat serviced by an authorized Yamaha Sport Boat dealer before storage. However, the following procedures can be performed by the owner with a minimum of tools.

FUEL SYSTEM

Top off the fuel tank with fresh fuel, adding one ounce of Yamaha Fuel Conditioner and Stabilizer or an equivalent to each gallon of fuel. A full fuel tank is less likely to allow condensation to collect in the tank, reducing the chance of contaminated fuel. Running the engines with treated fuel during cooling system flushing will also help protect carburetors and fuel lines.

NOTE: Use of Yamaha Fuel Conditioner and Stabilizer eliminates the need to drain the fuel system. Consult your Yamaha dealer or other qualified mechanic if the fuel system is to be drained instead.

FUEL SHUT-OFF PROCEDURE

Your Sport Boat is equipped with fuel supply shut-off valves. When storing your boat for more than 30 days, it is recommended that you turn off the fuel supply valves. This isolates fuel in the fuel tank and helps prevent contamination of the fuel system during storage.

To turn the fuel supply off, lift the center passenger seat base cushion. Remove the fuel shut-off valve access cover by unscrewing it. Once the cover is off, turn both fuel valve levers clockwise 90° until they are perpendicular to the fuel lines 1.

To turn the fuel supply on, turn each lever counter clockwise to the in line position 2.Remember that both valves must be on for both engines to receive fuel from the fuel tank.

Cooling system flushing is essential to prevent the cooling system from clogging up with salt, sand, or dirt.

1) Open the cap for the engine y ou are going to flush. Press the flush kit garden hose adapter into the flush hose connector and turn until they are securely connected.

2) Start the engine, then immediately turn on the water supply fully.

" Never turn on the water before

starting the engine. The water could flow back through the muffler into the crankcase causing severe engine damage.

" Be sure to turn on the water

immediately after starting the engine to prevent engine overheating.

3) Run the engine at a fast idle for 10~15 minutes.

4) Turn off the water supply, then drain residual water from the exhaust system by alternately pushing the throttle lever up to half throttle and back for 10 to 15 seconds. Shut off engine.

Never have the water on when the engine is not running. The water could flow back through the muffler into the crankcase causing severe engine damage. Do not run the engine for more than 15 seconds after the water supply has been turned off to avoid engine overheating.

5) After stopping the engine, remove the garden hose adapter.

6) Replace the cap securely.

7) Repeat the flushing procedure for the other engine.

LUBRICATION

To reduce the risk of fire or explosion: Never pour or spray gasoline, or any other substance except engine fogging oil through the hole in the carburetor silencer cover.

" Do not attempt to run the engine

at full throttle or for more than 15 seconds while the boat is out of the water. The engine may overheat and/or seize.

SPARK PLUG CLEANING AND ADJUSTMENT

The spark plug is an important engine component and is easy to inspect.The condition of the spark plug can indicate something about the condition of the engine.For example, if the center electrode porcelain is very white, this could indicate an intake air leak or carburetion problem in that cylinder.

Do not attempt to diagnose any problems yourself. Instead, take the Sport Boat to a Yamaha Sport Boat dealer. You should periodically remove and inspect the spark plug because heat and deposits will cause the spark plug to slowly break down and erode. If electrode erosion becomes excessive, or if carbon and other deposits are excessive, you should replace the spark plug with another of the correct type.

Before installing the spark plug, measure the electrode gap with a wire thickness gauge; adjust the gap to specification if necessary.

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.

NOTE: Before installing the spark plug cap, be sure to wipe off any water on the spark plug or inside the cap. Push the spark plug cap down until it clicks.

NOTE: If a torque-wrench is not available when you are fitting a spark plug, a good estimate of the correct torque (with a new gasket) is 1/4 to 1/2 turn past finger-tight. Have the spark plug adjusted to the correct torque as soon as possible with a torque wrench.

When removing or installing a spark plug, be careful not to damage the insulator.A damaged insulator could allow external sparks, which could lead to explosion or fire.

Standard spark plug: BR8HS

Spark plug gap: 0.6~0.7mm (0.024~0.028 in)

Spark plug torque: 25 Nm (2.5 m-kg, 18 ft-lb)

& SPECIAL PROCEDURES

EMERGENCY

PROCEDURES

TOWING THE SPORT BOAT

➀

Bow eye

The Sport Boat should be towed only if it becomes inoperative.

The towing rope should be long enough so that the Sport Boat will not collide with the towing boat when slowing down. A good rule of thumb is a tow rope which is three times the combined length of the towing boat and the Sport Boat.

Tow the Spor t Boat using the bow eye only .Tow the boat at a “no wake”speed.

Do not tow the Sport Boat at speed fast enough to leave a wake. Severe engine damage could result because water can flood the nonoperating engines through the cooling water intake.

The operator of the towing boat must keep speed to a minimum and avoid traffic or obstacles which could be a hazard to the driver on the Sport Boat.

RUNNING ON ONE ENGINE

If one engine becomes inoperative, the properly running engine can be used to return to shore. Operate at a “no wake” speed to prevent water from flooding the non-operating engine through the cooling water intake.

Do not operate the Sport Boat above a “no wake” speed with just one engine. Severe engine damage could result because water can flood the non-operating engines through the cooling water intake.

JUMP STARTING

➀

Negative (–) jumper cable

➁ Positive (+) jumper cable

If the boat battery runs down, the engines can be started in an emergency using a 12-volt battery and jumper cables.

SEVERE INJURY OR DEATH MAY RESULT IF YOU IGNORE ANY OF THE FOLLOWING:

● If blower will not operate, venti-

late engine compartment by opening engine compartment hatch for several minutes before attempting jump starting.

● Do not connect the negative (–)

jumper cable to the negative (–) terminal of the dead battery. Sparks could ignite battery or fuel vapors, which could cause an explosion.

To connect the jumper cables:

1) Connect the positive (+) terminal of the dead battery to the positive terminal (+)of the booster battery with the positive jumper cable.

2) Connect one end of the negative (–) jumper cable to the negative (–) terminal of the booster battery.

3) Connect the other end of the negative (–) cable to an unpainted bolt on the cylinder head.

Be sure all connections are secure and correct before attempting to start the engine. Any wrong connection may damage the electrical system.

4) Start the engine, then disconnect the cables by reversing the above steps.

Do not turn the starter motor for more than 5 seconds. If the engine does not start in 5 seconds, release the starter switch and try again after 15 seconds. Continuous cranking for more than 5 seconds will discharge the battery and the engine will not start. The starter motor may also be damaged if it is engaged continuously for more than five seconds.

JET PUMP CLEAN-OUT PROCEDURE

SEVERE INJURY OR DEATH MAY RESULT IF YOU IGNORE ANY OF THE FOLLOWING:

● Turn off and remove both ignition

keys,remove lany ard,and wait f or all movement to stop before removing access port caps.

● Never override interlocks to run

engine with hatch open.

● The impeller has sharp edges. Be

careful when reaching into jet pump area.

If weeds or debris get caught in the intake or impeller, cavitation can occur, and though the engine speed rises, forward thrust will decrease. If this condition is allowed to continue, pump damage can occur and the engines may overheat and seize. If there is any sign that the jet intake or impeller is clogged with weeds or debris, follow this cleanout procedure.

1) Turn off and remove ignition keys, remove lanyard, and wait for all movement to stop.

2) Lift the hatch on the rear platform.

3) Check that the retaining cord is securely attached to the cap and retaining strap. Press the release button and lift the cap up out of the port. Set the cap where it cannot be accidentally knocked overboard.

4) Remove any weeds or debris from the drive shaft, impeller, pump housing, and steering nozzle. If you cannot remove the debris, consult your Yamaha Sport Boat Dealer.

5) To reinstall the access port cap, first clean off any sand or other foreign matter from the cap or port surfaces. Insert the cap so that its projection faces the bow and lines up with the slot in the access port wall.

6) Press the T-handle down firmly to lock the cap in place. Pull up forcefully on the handle to be sure it is locked.If a strong pull will move the handle, it is not locked securely – the cap could be forced out by water pressure during operation.

● Be sure the caps are locked

securely in place. Otherwise the cap could be forced out of the access ports by water pressure, causing loss of performance and possible damage.

● The hatch cover has interlocks to

shut off the engines should the hatch be accidentally opened during operation. The engines will not restart unless the hatch is closed and latched.
