NOTICE: Excessive water in the engine
compartment can splash into the engine,
which can result in severe damage.
[ECJ00341]
This watercraft is equipped with a convention-
al jet vacuum bilge draining system and an
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 from the electric bilge
pilot outlet at the stern.
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. NOTICE:
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
enter 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.

EJU32651Jet 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, clean
it. (See page 95 for jet intake cleaning proce-
dures.)
If the watercraft is operated while the jet in-
take is clogged, cavitation could occur, reduc-
ing jet thrust, and possibly damaging the jet
pump. In some cases, the engine may over-
heat because of lack of cooling water, and
damage to the engine could result. Cooling
water is fed to the engine by the jet pump.
