WINTERIZATION CHECKLIST FOR
BOATS STORED ON LAND
Proper winterization of your boat in regions where
temperatures fall below freezing is necessary.
Failure to do so will seriously damage its compo-
nents and systems. They include, but are not limited
to: generator, mufflers, air conditioner, strainers,
water heater, sump pump, head, holding tank, water
tank, sewer system, and water systems. As a result
of not being able to completely drain the water sys-
tems with a water heater installed, it is recommend-
ed that potable water system antifreeze be run
through the entire system at the time of winteriza-
tion. This needs to be COMPLETELY flushed before
using in the following spring.
Note: Chaparral strongly recommends having a
qualified dealer perform winterization proce-
dures for your boat.
Boat Storage
• Store boat in a bow high attitude.
• Remove hull drain plug.
• Pour one (1) pint (half liter) of 50% water and
antifreeze mixture in each bilge pump sump.
Engines
Important: In regions where temperatures fall
below freezing, winterizing your engine is nec-
essary. Failure to do so will seriously damage
the engine. Refer to the instructions in your
engine owner’s manual.
• Flush engines with fresh water.
• Remove engine drain plugs.
Refer to your Engine Operator’s Manual for detailed
information on preparing the engines for storage

tinuously while battery is stored.

remove excess grease from the terminals,
recharge as necessary and reinstall in the boat.

water.

back bottom half of the water valve on the head.
