Battery check

Make sure that the battery terminals are not
damaged and that the battery leads are con-
nected properly. WARNING! The battery
must always be fully charged and in good
condition. Loss of battery power may
leave you stranded. Never operate the
boat if the battery does not have sufficient
power to start the engine or if it shows any
other signs of decreased power.

Bilge water check

Make sure that no bilge water has collected in
the engine compartment and the fuel tank
compartment. If bilge water has collected in
the engine compartment and the fuel tank
compartment, drain it. (See page 77 for infor-
mation on draining the bilge water.)

Drain plug check

Loosen the drain plugs and remove them, and
then make sure that the plugs and the O-rings
on the hull drain plugs are not damaged and
that there is no foreign material on the threads
or the O-rings on the hull drain plugs.
NOTICE: Before installing the drain plugs,
clean the drain plug threads and the
O-rings on the hull drain plugs to remove
any foreign materials, such as dirt or sand.
Otherwise, the drain plugs could be dam-
1
aged, allowing water to enter the engine
compartment or the fuel tank compart-
ment. Make sure that the drain plugs are
tightened securely before launching the
boat. Otherwise, water may flood the boat
and cause it to submerge.

Securely install the drain plugs by tightening
