CHECKS

POST-OPERATION CHECKS

These post-operation procedures are
developed to help preserve the long-
term appearance and reliability of your
Sport 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 Sport 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 main-
tenance 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 Sport Boat compo-
nents.
1) After putting the Sport 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 4-1 for
the cooling system flushing proce-
dure.
2) 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.
