Exercise 2: Starting and stopping engine
Objective:
This exercise teaches you about how the engine starts and stops and how the watercraft
behaves after starting and while idling.
Skills:
Identifying and performing engine starting and stopping controls and procedures.
Directions:
Launch the watercraft and practice this exercise while standing next to it in water free
from weeds or debris and at least 60 cm (2 ft) deep from the bottom of the watercraft.
Never operate in water that is less than 60 cm (2 ft) deep, otherwise pebbles or sand
could be sucked into the jet intake, causing impeller damage or engine overheating.

Exercise 2: Starting and stopping engine
Drill 1: Starting the engine
1. Press the unlock button 1 on the remote control transmitter to deactivate the security
system. (See the “Yamaha Security System” section in the owner’s/operator’s manual
for more information.)
2. Attach the engine shut-off cord 2 to your wrist. Insert the clip 3, under the engine
shut-off switch 4. Make sure to keep the engine shut-off cord free from the handlebars
so the engine stops if the operator falls off. The clip may not pull free if the cord is
wrapped around the handlebars.
3. Push the start switch 5 (green button).
(Do not squeeze either the throttle lever or RiDE lever. Otherwise, the engine will not
start.)
4. Release the start switch as soon as the engine starts to run.

Exercise 2: Starting and stopping engine
Drill 2: Stopping the engine
1. Release the throttle lever and let the engine slow to idle.
2. Push the engine stop switch 1 (red button). The ignition circuit opens and stops the
engine immediately.
3. Practice pulling the engine shut-off cord to remove the clip from the engine shut-off
switch.
Tips:
1. Attach the engine shut-off cord to your left wrist before starting the engine. To prevent
accidental starting, always remove the clip from the engine shut-off switch when the
engine is not running.
2. Do not operate the start switch for more than 5 seconds at a time. Never push the start
switch while the engine is running.
3. If the engine does not start in 5 seconds, release the start switch and try again after
15 seconds. Continuous cranking for more than 5 seconds will discharge the battery
and the engine will not start.
4. When the engine starts, thrust from the jet unit will move the watercraft. Squeezing the
throttle lever produces more thrust. Apply only enough throttle to keep the engine run-
ning.

Exercise 3: Boarding and balancing
Objective:
This exercise trains you to board the watercraft in deep water after falling off, and to upright
a capsized watercraft. Repeat these exercises until you can perform them without difficulty.
Skills:
Boarding in deep water and balancing at a standstill.
Directions:
Practice this exercise near shore before going out into open water.
The heavier the weight of an operator, the more difficult it will be to balance the watercraft.
These exercises should be done without starting the engine.
Attach the engine shut-off cord to your wrist and keep the watercraft afloat in water that
is at least chest deep.
Drill 1: Boarding the watercraft
1. Swim to the rear of the watercraft, lower the reboarding step with one hand and hold it
in place.
2. Put one foot on the step, and then grasp the reboarding grip with your other hand.

Exercise 3: Boarding and balancing
3. Pull yourself up onto the boarding platform and grasp the handgrip, and then move to the
seat and sit astride.
4. With the engine shut-off cord attached to your wrist, install the clip to the engine shut-
off switch.
5. Grip the handlebars firmly with both hands and place both feet in the footwell.
6. Practice boarding and balancing several times until you can maintain good balance of
the watercraft during the entire process.

Exercise 3: Boarding and balancing
Drill 2: Uprighting a capsized watercraft
Do not leave the watercraft capsized longer than necessary to upright it again. More
water may enter the engine compartment the longer the watercraft is capsized.
1. To practice uprighting, first purposely capsize the watercraft.
2. Remove the clip from the engine shut-off switch.
3. Swim to the rear of the watercraft. Turn the watercraft over by pulling on the ride plate
with one hand while pushing down on the gunwale with your other hand or your foot.
4. Start the engine and operate the watercraft above planing speed as straight as possible
for at least 2 minutes to discharge any water remaining in the engine compartment.
(See the “Capsized watercraft” section in the owner’s/operator’s manual for more infor-
mation.)

Exercise 4: Trolling speed maneuvering
Objective:
This exercise familiarizes you with the watercraft’s handling characteristics at trolling
speed. It teaches techniques you will use when beaching, docking, or approaching
objects.
Skills:
Starting and turning at trolling speed.
Directions:
Drill 1: Moving straight and turning at trolling speed
1. Board the watercraft, and check for people, objects and other watercraft.
2. Start the engine and go straight ahead.
3. Begin to turn, making a large figure eight about 15–21 m (50–70 ft) long. Do not apply
throttle.
Drill 2: Making full-lock turns at trolling speed
1. Turn the handlebars as far as possible in either direction. Allow the watercraft to turn
360°.
2. Practice turning both clockwise and counterclockwise to get a feel for how the water-
craft responds to handlebar movement.

Exercise 5: Sub-planing speed maneuvering
Objective:
This exercise shows you how to move ahead, turn in small circles, and combine the two
maneuvers to make a figure eight.
Skills:
Throttle control and slow to medium speed turning.
Directions:
Steering
Your watercraft is steered by a combination of applying throttle and turning the
handlebars1. When the handlebars are turned, the angle of the jet thrust nozzle 2 at the
stern is changed, which changes the direction of the watercraft.
Since the strength of the jet thrust determines the speed and direction of a turn, the
throttle must always be open when attempting a turn, except at trolling speed.

Exercise 5: Sub-planing speed maneuvering
Stopping
The watercraft is not equipped with a separate braking system. The watercraft slows
down by water resistance or, when operating in reverse, by the water jet. The watercraft
slows down as soon as the throttle lever is released, 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.
From full speed, the watercraft comes to a complete stop due to water resistance in
approximately 110 m (360 ft) after the throttle lever is released or the engine is stopped,
although this distance will vary depending on many factors, including gross weight, water
surface conditions, and wind direction.
If the RiDE lever is squeezed to slow down, the stopping distance is approximately 30%
shorter than when the RiDE lever is not used. However, this distance will vary depending
on many factors, including gross weight, water surface conditions, and wind direction.
Drill 1: Moving forward and turning in large ovals
1. Gradually accelerate forward to sub-planing speed, and then make a gradual right turn
while maintaining your speed.
2. Repeat the drill, making a gradual left turn.
3. Repeat the drill, traveling forward and turning to make a complete oval.

Exercise 5: Sub-planing speed maneuvering
Drill 2: Turning in circles
1. Make large circles, turning to the right. Gradually decrease the size of the circles while
keeping your speed constant.
2. Repeat the drill, turning to the left.
Drill 3: Making a figure eight
1. Combine the above drills to make a large figure eight.
2. Repeat the drill, making the figure eight smaller each time.
Drill 4: Understanding how throttle affects turns
1. Gradually accelerate to sub-planing speed while traveling in a straight line. Release the
throttle lever and then turn the handlebars as far as possible to the right or left.
2. Notice that you have rapidly decreasing ability to turn the watercraft and that the water-
craft does not respond to handlebar input once the engine slows down after the throttle
lever is released.
3. Gradually re-apply throttle to see how the watercraft responds with throttle again.
Tips:
To make tight turns at these speeds you must apply more throttle while you are turning
the handlebars.
