Prior To Winter Storage; Engine Flush Out - Four winns Horizon 210 Owner's Manual

C. Prior to Winter Storage
1. Remove as many cushions as possible. Remove
storage lids or hatches. Open as many locker doors,
as possible. Leave these areas open to improve
ventilation.
2. Spray the weather covers and the boat upholstery
with Lysol Spray Disinfectant™. Enclosed areas
such as storage locker areas should also be sprayed
with Lysol Disinfectant™.
3. Place small dishes of rodent poison such as D-Con™
in a number of areas around the boat. Be sure dishes
are placed near the head and the engines, as ro-
dents will destroy upholstery, water intake and dis-
charge hoses.
4. If the boat will be in outside storage, properly sup-
port a storage cover and secure it over the boat.
DO NOT secure the cover tightly to the boat. This
does not allow adequate ventilation and can lead to
dry rot. DO NOT store the boat in a damp storage
enclosure. Excessive dampness can cause electri-
cal problems, corrosion, and dry rot.
5. DO NOT use the bimini top or camper top as a win-
ter storage cover. The life of these covers may be
significantly shortened if exposed to harsh weather
elements for long periods.
Placing an electric or fuel burning heating unit
in the bilge of the boat during cold weather could
cause fire or explosion and is not recommended.
NOTICE
Boats stored outside in areas with heavy snow
accumulation are more susceptible to damage,
and should be inspected regularly during the win-
ter months
6. Engine should be winterized according to
the engine manufacturers manual.

Make sure that no section of flush hoses are in
contact with moving or hot engine parts or abra-
sive surfaces such as screw threads, sharp
edges, etc., which could damage the hoses.
Damage to the hoses could cause leaks and
possible flooding of the engine compartment.
Periodically check hoses for abrasions.
NOTICE
The flush out kit should only be used with the
boat in the water and the engine OFF.
To flush out the engine, follow the instructions below.
1. Do not run engine during flushing procedure.
2. Remove cap from coupling and attach swivel con-
nector.
3. Attach water supply hose to swivel connector.
4. Turn water on and allow water to flush the engine
and exhaust manifold for five to ten minutes.
5. Turn water off. Disconnect hose; replace and tighten
cap securely.
Reinstall cap onto coupler after flushing. Floo-
ding of the engine compartment will occur if the
cap is not installed and tightened.
