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. This extended
mooring is not recommended. Proper
flushing of the cooling system on each
engine is not possible with the boat in
the water. In addition, long-term moor-
ing can increase the need for mainte-
nance as well as accelerate the rate of
deterioration of sacrificial anodes and
other components. If you do decide
to moor your boat, be sure to remove
it periodically to clean the hull and jet
pump area. The frequency of mainte-
nance will depend upon whether the
water is salt or fresh and 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 system from
clogging up with salt, sand, or dirt.
Refer to page 4-1 for the cooling
system flushing procedure.
2) Drain residual water from the exhaust
system by starting the engine, then
alternately pushing the control lever
up to half throttle and back to idle 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.
