GENERAL MAINTENANCE

O - 1

WINTERIZATION

A. Prior to Lifting for Winter Layup
1. Pump out the head (dockside discharge), and be
sure the holding tank is empty. Flush the head hold-
ing tank with soap, water and a deodorizer (e.g., Lysol
Liquid). Add more water if necessary. Have the
cleaning solution pumped out.
2. Have the fuel tank either 75%-80% full (to allow for
expansion) or completely empty. See the Engine
Owners manual for recommendations. Also, check
with the dry dock operators for recommendations.
If winter storing with a full fuel tank, gasoline
winterizer such as Sta-bil® fuel conditioner will re-
duce varnishing, condensation, etc.
NOTICE
If the fuel has been treated with winterizer, run
engines for ten minutes to make sure the treated
fuel is present in all lines and parts of the en-
gine.
3. Drain water from the fresh water system and the hot
water heater.
4. Winterize the engine and drive systems as recom-
mended in the Engine Owners manual. Portions of
this winterization procedure may require that the boat
be lifted.
5. Lift the boat only at the designated "sling" labels.
See Section M-7 Hull Support in this manual for addi-
tional details.
B. After Lifting
1. Remove the drain plug.
2. Thoroughly wash the fiberglass exterior, especially
the hull bottom. Remove as much marine growth
as possible.
3. Lower boat onto cradle properly or place boat on
trailer. Be sure boat is adequately supported. The
boat should be raised slightly under the forward sup-
ports or trailer tongue to improve drainage to the
transom drain.

4. Be sure all the water is completely drained from the
fresh water system. Disconnect all hoses, check
valves, etc. and blow all the water from the system
using very low air pressure. The use of non-toxic,
fresh water system anti-freeze is recommended as
an alternative to disassembling the water system.
Refer to Section G-7 System Maintenance in this
manual for information on winterizing the water sys-
tem.
5. Winterize the head as recommended by the head
manufacturer. If the boat is equipped with a holding
tank, mix some anti-freeze solution and pour it into
the head. Transfer some of the anti-freeze to the
holding tank by flushing the head. Also, refer to Sec-
tion G-8 System Maintenance for additional informa-
tion.
6. Drain or winterize the air conditioning and generator
system (278 model only). Follow the appropriate
manufacturer's directions. Be sure all water intake
filters are drained thoroughly.
7. Ensure that all water is removed from the sump
pump, bilge pump and bilge pump lines. Dry the
hull bilge, and self-bailing cockpit drain troughs.
Water freezing in these areas could cause damage.
See Section H-3 Hull Drainage Systems.
8. Remove the battery(s) and store in a cool place.
Clean the battery using clear, clean water. Be sure
the battery has sufficient water and clean terminals.
Keep the battery charged throughout the storage
period. DO NOT store the battery on a concrete
floor or other damp or conductive surface.
9. Drain the alcohol out of the stove (if applicable) and
store alcohol in a cool, dry place away from heat or
spark.
10. Clean the boat interior thoroughly. Vacuum carpets,
and dry clean drapes and upholstery jackets as nec-
essary.
11. Scrub the hull bottom and wash exterior fiberglass
components, wax lightly.
12. Clean exterior upholstery with hand dishwashing
soap and water, rinse, and dry thoroughly.
