electric bilge draining system. The electric
bilge draining system is operated when the
engine is running. When excess water reach-
es the water inlet of the electric bilge pump,
the water is discharged via the exhaust pas-
sage from the jet thrust nozzle.
A small quantity of water will remain in the
bilge and should be drained manually. To
drain any residual water, beach the watercraft
and perform the following procedure.
To drain water from the bilge:
(1) Remove the stern drain plugs.
(2) Raise the bow of the watercraft until the
water drains.
(3) After the water has drained, wipe the
bilge with dry rags to make sure that it is
thoroughly dry.
(4) Install the stern drain plugs.
CAUTION:
ECJ00360

Before installing the stern drain plugs,
clean the drain plug threads to remove
any foreign materials, such as dirt or
sand. Otherwise, the stern drain plugs
could be damaged, allowing water to en-
ter the engine compartment.

Make sure that the stern drain plugs are
tightened securely before launching the
watercraft. Otherwise, water may flood
the engine compartment and cause the
watercraft to submerge.

(3) Check that the QSTS selector turns
smoothly when the lever is squeezed and
held in place.
(4) Check that the angle of the jet thrust noz-
zle changes when the QSTS selector is
shifted from neutral to bow up or bow
down.
If the mechanism does not work properly,
have a Yamaha dealer service it.
EJU32650Jet 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 76 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
may have collected around the jet in-
take.
