Operation

WARNING

EWJ00490

Before starting the engine, always check
the operation of the throttle lever.

EJU32600

Steering system 

Check the handlebars for looseness.
Turn the handlebars as far as possible to the
right and left to make sure that operation is
smooth and unrestricted throughout the
whole range. Also, make sure that the jet
thrust nozzle moves as the handlebars are
turned, and that there is no free play between
the handlebars and the jet thrust nozzle.

EJU32620

Steering pole 

Check the steering pole for looseness.
Move the steering pole up and down to make
sure that operation is smooth and unrestricted
throughout the whole range. Also, make sure
that the steering pole does not have any side
play.

EJU32650

Jet intake 

Carefully check the jet intake for weeds, de-
bris, or anything else that might restrict the in-
take of water. If the jet intake is clogged,
cavitation could occur, reducing jet thrust, and
possibly damaging the jet pump.
In some cases, the engine may overheat be-
cause of lack of cooling water, and damage to
the engine could result. Cooling water is fed to
the engine by the jet pump. (See page 71 for
jet intake cleaning procedures.)

WARNING

EWJ00470

●

Keep away from the intake grate while
the engine is on. Items such as long hair,
loose clothing, or PFD straps can be-
come entangled in moving parts, result-
ing in severe injury or drowning.

●

Stop the engine and remove the clip
from the engine shut-off switch before
removing any debris or weeds, which
