POST-OPERATION CHECKS

These post-operation procedures are
developed to help preserve the long-
term appearance and reliability of your
boat. Perform these procedures as
soon as possible after the boat is
loaded back on the trailer after the
day's use.
Some owners plan to moor their boat
seasonally, rather than keeping it on
the trailer between uses. The proce-
dures described in this section may not
be possible if your boat is moored in
the water. Boats which are moored will
require periodic removal from the water
to clean the hull and jet pump area. The
frequency of this maintenance will
depend upon whether the water is salt
or fresh, as well as other local water
conditions.
CAUTION:
Leaving the boat in the water for
extended periods will accelerate the
rate of normal deterioration of the
jet pump components and hull fin-
ish. Stray electrical voltage in the
water, marine organisms, and salt-
water corrosion are a few of the con-
ditions that can adversely affect the
life of many boat components.
1) After putting the boat on the trailer,
flush cooling system on each
engine to prevent the cooling sys-
tem from clogging up with salt,
sand, or dirt. Refer to page 4-2 for
the cooling system flushing proce-
dure.
2) Drain residual water from the
exhaust system by starting the
engine then alternately pushing the
throttle lever up to half throttle and
back for 10 to 15 seconds.
CAUTION:
Never run the engine at full throttle
or for more than 15 seconds while
the boat is out of the water. The
engine may overheat and/or seize.
3) Wash down the hull, helm, and both
jet drive units with fresh water.
4) Open the rear platform hatch, and
check for any water pooled on top of
the clean-out port caps. If water is
found, remove the caps, let water
drain, then reinstall the caps. See
Page 5-5 for more information.
