Always avoid using your watercraft in areas
where weed growth is thick. If operating in
weeded areas is unavoidable, alternately
squeeze the throttle lever and relax your grip
on the throttle lever to vary the engine speed.
Weeds tend to become clogged more when
operating at a steady speed and at trolling
speed. If weeds may have clogged the intake area, clean the jet intake. (See page 66 for in-
formation on the jet intake.)
EJU41060After removing the watercraft from the
water

Post-operation care
WARNING
EWJ00320
Always turn the fuel cock knob to “OFF”
when storing the watercraft, otherwise
fuel could leak out into the engine or en-
gine compartment, which would 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 deterioration
of the jet pump and hull. Marine organisms
and corrosion are some of the conditions that
can shorten the life of many watercraft com-
ponents.
EJU33518Flushing the cooling water passages
NOTICE
ECJ01360
