1 SAFETY INFORMATION SAFETY INFORMATION education requirements. Always check state and local boating laws before you operate the Jet Boat. ● The operator is responsible for the safety of his or her passengers as well as his or her own personal safety. WARNING SEVERE INJURY OR DEATH MAY RESULT IF YOU IGNORE ANY OF THE FOLLOWING SAFETY INFORMATION. ● Before operating the Jet Boat, read this entire manual, the Operation Instruction card, and all warning labels on the Jet Boat.
SAFETY INFORMATION REQUIRED EQUIPMENT 1 ADDITIONAL EQUIPMENT RECOMMENDATIONS 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 Jet Boat which are less than 26 feet long.
1 SAFETY INFORMATION APPAREL ● Because of the drowning hazards associated with water sports, the operator and passengers must always wear a U.S. Coast Guardapproved vest-type personal flotation device (PFD). Be sure the PFD is properly fitting and in good condition. ● You might also consider gloves designed for water sports to help protect hands during operation, as well as while launching and docking your boat. ● You may want to consider eye protection.
SAFETY INFORMATION 1 ● Always perform the pre-operation checks on page 3-4 before operating to be sure your equipment is working properly. ● The operator should always attach the engine stop switch lanyard (cable) to his PFD so that the engines will stop if the operator accidentally leaves the helm. Failure to attach the lanyard could result in a runaway boat if the operator is ejected.
1 SAFETY INFORMATION ● Maintain a safe distance from other boats or watercraft, and also watch for boat's 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. ● If you are pregnant or in poor health, ask your doctor's advice on whether it is safe for you to ride this Jet Boat. ● Do not attempt to modify this Jet Boat! Modifications to your boat may reduce safety and reliability, and may make the boat illegal for use.
SAFETY INFORMATION 1 CRUISING LIMITATIONS ● Keep hands, feet, hair, and all other parts of your body and clothing away from jet intakes on the bottom of the hull while engine is running because they could be caught in the intake. Stop the engine and remove the lanyard before removing any debris or weeds which may have collected around the jet intake. Refer to the Jet Pump Clean-Out procedures on page 5-5 for further Information.
1 SAFETY INFORMATION Be alert to the possibility of adverse weather. Take note of marine weather forecasts and the prevailing weather conditions before setting out in your Jet Boat. NIGHT OPERATION ● When using your Jet Boat before dawn and 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 2-13 for instructions. ● Leave a “float plan” with a responsible person on shore.
SAFETY INFORMATION WATERSKIING You can use the Jet Boat to tow a waterskier, using the tow eye provided. Do not attach the tow rope to any other location on the boat. It is the boat operator’s responsibility to be alert to the safety of the waterskier and others. Know and follow all state and local waterskiing regulations in effect for the waters in which you will be operating.
1 SAFETY INFORMATION BASIC BOATING RULES STEERING AND SAILING RULES AND SOUND SIGNALS RULES OF THE ROAD 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 rightof-way, and what each vessel should do. Your Yamaha Jet Boat is legally considered a power boat.
SAFETY INFORMATION RULES WHEN ENCOUNTERING VESSELS There are three main situations which 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 travelling across the other vessel's path) 1 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.
1 SAFETY INFORMATION 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.

1 SAFETY INFORMATION Reading Buoys and Other Markers The waters of the United States are marked for safe navigation by the lateral system of buoys. 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 markings on these buoys are oriented from the perspective of being entered from seaward (the boater is going towards the port).
SAFETY INFORMATION 1 ACCIDENT REPORTING ENJOY YOUR JET BOAT RESPONSIBLY Boat operators are required by law to file a Boating Accident Report with their state boating law enforcement agency if their boat has been involved in any of the following boating accidents: You share the areas you enjoy when operating your Jet Boat with others and with nature. So your enjoyment includes a responsibility to treat other people, and the lands, waters, and wildlife with respect and courtesy. 1.

OPERATION FUEL REQUIREMENTS 3 gasoline (petrol) in your eyes, get immediate medical attention. GASOLINE (PETROL) ● If any gasoline (petrol) spills onto your skin, immediately wash with soap and water. Change clothing if gasoline (petrol) spills on it. Use regular unleaded 87 octane (R+M ÷ 2) gasoline (petrol). WARNING GASOLINE (PETROL) AND ITS VAPORS ARE HIGHLY FLAMMABLE AND EXPLOSIVE! CAUTION: Use only fresh gasoline (petrol) that has been stored in clean containers.
3 OPERATION OIL INJECTION SYSTEM of increased deposits in the combustion chamber. When enough deposits collect, piston rings begin sticking. Performance drops and engine wear increases dramatically. 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 (petrol) into the fuel tank and oil into the oil tank.
OPERATION GASOLINE (PETROL) AND ENGINE OIL FILLING 3 FILLING THE OIL TANK FILLING THE GASOLINE (PETROL) 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. Open the fuel tank filler cap, and slowly add fuel to the fuel tank. Be careful not to spill fuel or overfill the tank. WARNING ● Oil in the bilge is a serious fire hazard.
3 OPERATION PRE-OPERATION CHECKS WARNING If any item in the Pre-Operation check is not working properly, have it inspected and repaired before operating the Jet Boat. Otherwise an accident could occur. CHECK LIST Before Operating this Jet Boat, perform the following checks: ITEM PAGE REF. CHECK BEFORE LAUNCH OR OPERATION: STEERING Check for proper steering operation. 3-5 THROTTLE Check for proper throttle operation. 3-5 SHIFTING Check for proper shift operation.
OPERATION 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. 3 Throttle CHECK POINTS Steering 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.
3 OPERATION This Jet Boat is included in the Class 1 inboard boat classification of the U.S. Coast Guard. 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 under Coast Guard jurisdiction. In addition, most state and local boating laws also require that the craft carry a USCG-approved fire extinguisher wherever the boat is operated. A fire extinguisher is not standard equipment with this boat.
OPERATION Jet Intakes 3 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 level. Add fuel if necessary. NOTE: The fuel level is most accurate when the boat is sitting level on the trailer or in the water.
3 OPERATION 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. A drain plug is located at the center of the stern to allow more complete draining when the boat is removed from the water.
OPERATION 3 Engine Compartment Lights Operate the bilge blower for at least 4 minutes before starting the engines. Open engine hood and check to be sure no gasoline vapors are present. Check for fuel leaks or loose electrical connection. Check for proper operation of the bow, stern, and instrument lights by pressing the switch on the control panel. 1 ➀ Blower motor WARNING Gasoline vapors can explode.
3 OPERATION Horn Press the horn switch to be sure the horn operates. Cooling-Water Pilot Outlets Check that water comes out from the pilot outlets while engine is running in the water. Refer to page 2-11 for correct operation of the device. Engine Stop Switch NOTE: It may take up to 20 seconds for water to reach the pilot outlets when first launching the boat. The amount and force of the exiting water will vary with engine rpm.
OPERATION BIMINI TOP Raising from the fully collapsed storage position. 3 4) Unfold the top by pulling to the bow of the Jet Boat. 1) Release the Velcro strap securing the rear support poles. 5) Check that the rear support poles are at the highest position. 2) With an assistant, raise the top and secure the rear support poles to the rear support pole mounts with the lock pins. 6) Attach the snap hooks to the strap eyes. 7) Lower the rear support poles to the lower position.
3 OPERATION Storing In The Upright Position 1) Raise the rear support poles to the highest position. 2) Unhook the front straps and pull the top to the back. 3) Roll the fabric around the frames and zip the storage cover in place. CAUTION: Do not trailer the boat with the Bimini top in the fully extended or upright storage positions. Put the cover in the fully collapsed position to avoid damage. Trailering With The Bimini Top The Bimini top must be secured to the boat when it is being trailered.
OPERATION OPERATION 3 WARNING STARTING THE ENGINES WARNING SEVERE INJURY OR DEATH MAY RESULT IF YOU IGNORE ANY OF THE FOLLOWING: 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. ● Before operating your Jet Boat, become familiar with all controls.
3 OPERATION 1 2 NOTE: Before the first start-up, remove the fuel tank filler cap to release any built-up pressure in the tank because of fuel expansion. ➀ Engine stop switch ➁ Lock-plate with lanyard NOTE: It is not possible to start the engine with the lock-plate removed from the engine stop switch. However, the starter motor will turn the engine over. 4) Pull the choke knob all the way out. 3) Attach the lanyard clip to your PFD.
OPERATION 3 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 connected 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) Put the throttle levers in the idle position. Shift into Neutral. Turn the ignition key of one engine to “Start.” When the engine starts, release the key.
3 OPERATION STOPPING THE ENGINES BREAK-IN (RUNNING-IN) PROCEDURE The engine and other components require a break-in (running in) period to allow surfaces of moving parts to wear in evenly. This ensures proper performance and promotes longer engine life. CAUTION: 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.
OPERATION DRIVING YOUR JET BOAT GETTING TO KNOW YOUR JET BOAT Operating your Jet 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 Jet 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 Jet Boat to achieve the skill necessary to enjoy boating safely.
3 OPERATION 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 Jet Boat is designed for one operator and up to six passengers only. Never have more than seven people in the Jet Boat. Passengers should sit so the weight in the boat is balanced from side to side and bow to stern as much as possible.
OPERATION BOARDING FROM A DOCK OR LANDING JETTY 1) Board the boat from the side. One person should board at a time by stepping into the boat. Never jump in. Avoid stepping on slick gelcoat surfaces on the boat’s gunwales, especially if wet. As you make turns, remember that boats steer from the stern. As you make a turn to the right, for example, the stern of the boat swings to the left. This characteristic is particularly important to understand when maneuvering near obstacles such as docks or buoys.
3 OPERATION STOPPING 400 FT (122 m) 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. WARNING The Jet Boat is not equipped with a separate braking system. It is stopped by water resistance after the throttle levers are moved back to idle.
OPERATION Wind or current pushing boat toward dock: WIND OR CURRENT 3 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. 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.
3 OPERATION ANCHORING WARNING 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.
OPERATION 3 CROSSING WAVES You won't always have flat, smooth water. There will be waves, wakes from other boats, etc. SHARP WAVES The best way to cross waves or wakes is with the least "jolt" to you and the boat. Small waves are not as difficult to cross as larger waves. Crossing a sharp wave gives more of a jolt than a broad wave. BROAD WAVES To cross a wave, change your speed and the angle that you cross the wave. Usually, a slower speed and "quartering" the wave at an angle will reduce the "jolt.
3 OPERATION POST-OPERATION CHECKS POST-OPERATION CHECKS These post-operation procedures are developed to help preserve the longterm appearance and reliability of your Jet Boat. Perform 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 Jet Boat is moored in the water.
OPERATION 4) 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. 3 NOTE: This boat is equipped with an electric bilge pump that automatically removes excess water from the bilge while you are underway.
3 OPERATION TRAILERING HITCH WARNING Avoid accident and injury from improper trailering: ● The trailer must be matched for the Jet Boat’s weight and hull. ● The towing vehicle must have the capacity of pulling the load. Pulling a load that exceeds the Jet Boat’s 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.
OPERATION ● 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. 3 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 corners.
3 OPERATION LAUNCHING 5) Remove the bow line from the bow eye. 6) Back the trailer farther into the water until just the tops of the fenders show, then reset the parking brake. Board the boat and start it. If possible, remain on the trailer until the engines are warm and are responding to throttle. As a courtesy to other boaters, prepare your Jet Boat for launching before using the ramp. Each launch may have particular differences, such as ramp angle, prevailing wind, waves, and water currents.
OPERATION 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. CAUTION: ● 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.
