EJU33083Starting off
WARNING
EWJ00712
To avoid collisions:
Scan constantly for people, objects, and
other watercraft. Be alert for conditions
that limit your visibility or block your vi-
sion of others.
Operate defensively at safe speeds and
keep a safe distance away from people,
objects, and other watercraft.
Do not follow directly behind watercraft
or other boats. Do not go near others to
spray or splash them with water. Avoid
sharp turns or other maneuvers that
make it hard for others to avoid you or
understand where you are going. Avoid
areas with submerged objects or shal-
low water.
Take early action to avoid collisions. Re-
member, watercraft and other boats do
not have brakes. Do not release the
throttle lever when trying to steer away
from objects—you need throttle to
steer.

Post-operation care
WARNING
EWJ00331
Always place the watercraft upright in a
horizontal position when storing it, other-
wise fuel could leak out into the engine or
engine compartment, which could create
a fire hazard.
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 deteriora-
tion of the jet pump and hull. Marine organ-
isms and corrosion are some of the
conditions that can shorten the life of many
watercraft components.
