EJU31212 Throttle lever

• The throttle lever increases the engine speed when the lever is squeezed.

• The throttle lever returns automatically to its fully closed (idle) position when released.

EJU43342 RiDE lever (VX / VX Deluxe / VX Cruiser / VX Limited)

• When the RiDE lever is squeezed, the reverse gate lowers and the watercraft starts moving in reverse. If the watercraft is moving forward, the watercraft gradually slows down until it stops, and then the watercraft starts moving in reverse.

• When the RiDE lever is released, it automatically returns to its fully closed (idle) position and the reverse gate moves to the neutral position.

EJU31262 Steering system

• By turning the handlebars in the direction you wish to travel, the angle of the jet thrust nozzle is changed, and the direction of the watercraft is changed accordingly.

• Since the strength of the jet thrust determines the speed and degree of a turn, throttle must always be applied when attempting a turn, except at trolling speed.
• This model is equipped with the Yamaha Engine Management System (YEMS) that includes an off-throttle steering (OTS) system. It will activate at planing speeds should you attempt to steer the watercraft after releasing the throttle lever. The OTS system assists in turning by continuing to supply some thrust while the watercraft is decelerating, but you can turn more sharply if you apply throttle while turning the handlebars. The OTS system does not function below planing speeds or when the engine is off. Once the engine slows down, the watercraft will no longer turn in response to handlebar input until you apply throttle again or you reach trolling speed.

EJU35975 Cooling water pilot outlet

• When the engine is running, some of the cooling water that is circulated in the engine is discharged from the cooling water pilot outlet.

• There is a cooling water pilot outlet on the port (left) side of the watercraft. To check for proper operation of the cooling system, make sure that water is being discharged from the cooling water pilot outlet. If water is not being discharged from the outlet, stop the engine and check the jet intake for clogging. (See page 100 for information on the jet intake.)

TIP:

• It will take about 60 seconds for the water to reach the outlet after the engine is started.
• Water discharge may not be constant when the engine is running at idling speed. If this occurs, apply a little throttle to make sure that water discharges properly.

EJU40323 Water separator

• The water separator prevents water from entering the fuel tank by collecting any water that has entered the fuel tank breather hose if the watercraft was capsized.
• If water has collected in the water separator, drain it by loosening the drain screw.

To drain water from the water separator:

1. Place a drain pan or dry cloth under the water separator.
2. Gradually loosen the drain screw to drain the water. Catch the draining water in the drain pan or soak it up with the dry cloth so that it does not spill into the engine compartment. If any water spills into the watercraft, be sure to wipe it up with a dry cloth.
3. Securely tighten the drain screw until it stops.

• Operating your new watercraft can be a very enjoyable activity, providing you with hours of pleasure. However, it is essential to familiarize yourself with the operation of the watercraft to achieve the skill level necessary to enjoy riding safely.
• Before operating this watercraft, read this owner’s/operator’s manual, the Riding Practice Guide, the Riding Instruction card, and all labels on the watercraft. Pay particular attention to the safety information beginning on page 10. Also, watch the WaveRunner Basic Orientation Video linked to the following QR code. yamahawaverunners.com/orientation A DVD is also available your nearest dealer for your convenience.
• These materials should give you an understanding of the watercraft and its operation. Remember: This watercraft is designed to carry the operator and up to 2 passengers. Never exceed the maximum load limit or allow more than 3 persons (or 2 persons if a wakeboarder or water-skier is being pulled) to ride the watercraft at any time.

Learning to operate your watercraft

• Before operating the watercraft, always perform the pre-operation checks listed on page 63. The short time spent checking the watercraft will reward you with added safety and reliability.
• Check state and local laws before operating your watercraft.
• Operate defensively at safe speeds and keep a safe distance away from people, objects, and other watercraft. Select a wide area to learn in, where there is good visibility and light boat traffic.

• Use the buddy system—operate with someone nearby. Scan constantly for people, objects, and other watercraft. Be alert for conditions that limit your visibility or block your vision of others.
• You should grip the handlebars firmly and keep both feet on the floor of the footwell. Do not attempt to ride with passengers until your operating skills are fully developed.

Riding position

• Operator riding position: The operator should grip the handlebars firmly with both hands and sit astride the seat with both feet on the floor of the footwell.

• Passenger riding position: The passenger(s) should hold on firmly, either to the person in front of them or to the handgrip provided, and sit astride the seat with their feet on the floor of the footwell. Never allow a passenger to ride in front of the operator. (See page 18 for information on the riding position when pulling a wakeboarder or water-skier.)

Launching the watercraft

• When launching the watercraft, make sure that there are no obstacles around you. If the watercraft is launched from a trailer, someone should make sure that waves do not push the watercraft into the trailer.

Starting the engine on water

WARNING: Do not apply throttle when anyone is at the rear of the watercraft. Turn the engine off or keep it at idle. Water and debris exiting the jet thrust nozzle can cause severe injury.

To start the engine:

(1) VX Deluxe / VX Cruiser / VX Limited: If the lock mode is selected for the Yamaha Security System setting, select the unlock mode. (See page 32 for Yamaha Security System setting procedures.)

(2) Move the watercraft to an area that is free from weeds and debris, and has a water depth of at least 60 cm (2 ft) from the bottom of the watercraft. NOTICE: Never run the engine in water that is less than 60 cm (2 ft) deep from the bottom of the watercraft, otherwise pebbles or sand could be sucked into the jet intake, causing impeller damage and engine overheating. [ECJ00473]

(3) Attach the engine shut-off cord (lanyard) to your left wrist, and then attach the clip to the engine shut-off switch. (See page 33 for information on operating the engine shut-off switch.) WARNING! Check that the engine shut-off cord (lanyard) is attached correctly. If the engine shut-off cord (lanyard) is not attached correctly, it may not pull free when the operator falls off, allowing the watercraft to continue to run and cause an accident. [EWJ00582]

(4) With the throttle lever released, push the start switch (green button) to start the engine. (See page 33 for information on operating the start switch.)

Stopping the engine

• Release the throttle lever, and then push the engine stop switch (red button) to stop the engine. WARNING! You need throttle to steer. Shutting the engine off can cause you to hit an obstacle you are attempting to avoid. A collision could result in severe injury or death. [EWJ00602]

Leaving the watercraft

• If leaving the watercraft, remove the clip from the engine shut-off switch to prevent acci-dental starting or unauthorized operation by children or others.

Operating the watercraft VX-C:

When the engine is running, the watercraft will move forward at trolling speed even if the throttle lever is in the fully closed (idle) position.

VX / VX Deluxe / VX Cruiser / VX Limited: When the throttle lever is squeezed, the “F” (forward) shift indicator will be displayed and the watercraft will move forward. While the “F” (forward) shift indicator is displayed, the watercraft will move forward at trolling speed even if the throttle lever is in the fully closed (idle) position. (See page 37 for shift system operation procedures.)

Turning the watercraft

Steering control depends on the combination of handlebar 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 watercraft. The higher the engine speed, the more thrust produced.

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

A. More throttle produces higher thrust, so the watercraft will turn more sharply.

B. Less throttle produces lower thrust, so the watercraft will turn more gradually

C. Releasing the throttle lever completely 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 releasing the throttle lever, but once the engine slows down, the watercraft will no longer respond to handlebar input until you apply throttle again or you reach trolling speed.

At trolling speed, the watercraft can be turned gradually by handlebar position alone using just the amount of thrust available at idle

D. If the engine is stopped while riding, there is no thrust. The watercraft will go straight even though the handlebars are turned.

E. VX / VX Deluxe / VX Cruiser / VX Limited: If the RiDE lever is squeezed and the handlebars are turned when the watercraft is cruising at planing speed, the watercraft will turn gradually while slowing down.

This model is equipped with the Yamaha Engine Management System (YEMS) that includes an off-throttle steering (OTS) system. It will activate at planing speeds should you attempt to steer the watercraft after releasing the throttle lever (see condition C above). The OTS system assists in turning by continuing to supply some thrust while the watercraft is decelerating, but you can turn more sharply if you apply throttle while turning the handlebars. The OTS system does not function below planing speeds or when the engine is off. Once the engine slows down, the watercraft will no longer turn in response to handlebar input until you apply throttle again or you reach trolling speed.

Care and storage

Post-operation care

• After using the watercraft, always take it out of the water, clean it, and store it. Leaving the watercraft in the water for extended periods will accelerate the rate of normal deterioration of the jet pump and hull. Marine organisms and corrosion are some of the conditions that can shorten the life of many watercraft components.

Emergency procedures

Cleaning the jet intake and impeller

WARNING: Before attempting to remove weeds or debris from the jet intake or impeller area, shut the engine off and remove the clip from the engine shut-off switch. Severe injury or death could result from coming in contact with the rotating parts of the jet pump.

• If weeds or debris gets caught in the jet intake or impeller, cavitation can occur, causing jet thrust to decrease even though engine speed rises. If this condition is allowed to continue, the engine will overheat and may seize.

NOTICE: If weeds or debris gets caught in the jet intake, do not operate the watercraft above trolling speed until they have been removed. [ECJ00654]

• If there is any sign that the jet intake or impeller is clogged with weeds or debris, return to shore and check the intake and impeller. Always stop the engine before beaching the watercraft.

(1) Place a suitable clean cloth or carpeting underneath the watercraft to protect it from abrasions and scratches. Turn the watercraft on its side as shown. NOTICE: When turning the watercraft on its side, support the bow so that the handlebars are not bent or damaged. [ECJ02690]

(2) Remove any weeds or debris from around the jet intake, drive shaft, impeller, jet pump housing, and jet thrust nozzle. If debris is difficult to remove, consult a Yamaha dealer.

Raising the reverse gate (VX / VX Deluxe / VX Cruiser / VX Limited)

• If the RiDE system malfunctions and the reverse gate remains in the lowered position, the watercraft will not be able to move forward.
• After raising the reverse gate so that the watercraft can move forward, immediately return to shore and have a Yamaha dealer service the watercraft.

To raise the reverse gate:

(1) Stop the engine and remove the clip from the engine shut-off switch.

(2) Enter the water and move to the rear of the watercraft.

(3) Slide the shift rod joint toward the bow, and then disconnect the shift rod joint from the ball joint.

(4) Raise the reverse gate to the forward position.

TIP:

• While the shift rod is disconnected, the reverse gate will not move to the neutral position or reverse position even if the RiDE lever is squeezed.
• If the RiDE lever is squeezed while the shift rod is disconnected, the watercraft will move forward.

Jumping the battery

If the watercraft battery has run down, the engine can be started using a 12-volt booster battery and jumper cables.

Connecting the jumper cables

WARNING: To avoid battery explosion and serious damage to the electrical system:

• Do not reverse the polarity of the jumper cables when connecting to the batteries.
• Do not connect the negative (–) jumper cable to the negative (–) terminal of the watercraft battery.
• Do not touch the positive (+) jumper cable to the negative (–) jumper cable.

(1) Connect the positive (+) jumper cable to the positive (+) battery terminals of both batteries.

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

(3) Connect the other end of the negative (–) jumper cable to an engine hanger

4) Start the engine, and then disconnect the jumper cables by reversing the steps above. (See page 33 for information on starting the engine.)

Towing the watercraft

WARNING

• The operator of the towing boat must keep speed to a minimum and avoid traffic or obstacles which could be a hazard to the operator on the watercraft.
• The towline should be long enough so that the watercraft will not collide with the towing boat when slowing down.

If the watercraft becomes inoperative in the water, it can be towed to shore.

To tow the watercraft:

Use a towline that is three times the combined length of the towing boat and the watercraft.

(1) Securely attach the towline to the bow eye of the watercraft being towed.

(2) Sit astride the seat and hold on to the handlebars in order to balance the watercraft. NOTICE: The bow must be kept up out of the water during towing, otherwise water could flood the engine compartment or water could flow back into the engine, causing severe engine damage. [ECJ01331]

Tow the watercraft at 8 km/h (5 mph) or less.

NOTICE: Tow the watercraft at 8 km/h (5 mph) or less, otherwise water could flood the engine compartment or water could flow back into the engine, causing severe engine damage. [ECJ01322]

Submerged watercraft

If the watercraft is submerged or flooded with water, drain the bilge water from the engine compartment. Then, have a Yamaha dealer service the watercraft as soon as possible.

If the watercraft was submerged:

(1) Remove the watercraft from the water and drain the water from the storage compartments. (See page 52 for information on draining the storage compartments.)

(2) Drain the bilge water from the engine compartment. (See page 60 for information on draining the bilge water.)

(3) Have the watercraft serviced by a Yamaha dealer as soon as possible.

NOTICE: Be sure to have a Yamaha dealer inspect the watercraft. Otherwise, serious engine damage could result. [ECJ00792]
