Care and storage
Post-operation care
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 adversely affect the life of many water-
craft components.
Flushing the cooling water passages
Do not run the engine for more than 15
seconds on land without supplying water,
otherwise the engine could overheat.
Flush the cooling water passages to prevent
them from clogging with salt, sand, or dirt.
Use the Yamaha Watercraft Flush Kit to make
flushing easier.
See the instructions included with the flush kit
for proper installation.
(1) Place the watercraft in a horizontal posi-
(2) Remove the hood. (See page 27 for hood
removal and installation procedures.)
(3) Insert the garden hose adapter into the
flushing hose connector.
(4) Connect a garden hose to the garden
hose adapter.
(5) Connect the garden hose to a water tap.
(6) Make sure that the area around the wa-
tercraft is clear, and then start the engine.
Immediately after the engine starts, turn
the water supply on gradually until water
flows out continually from the cooling wa-
ter pilot outlet.
(7) Run the engine at idling speed for about
3 minutes watching the engine condition.
If the engine stops while flushing, turn the
water supply off immediately and perform
