C. Prior to Winter Storage
A. Volvo Penta Engine Flush Out
(Four Winns Installation)
Remove as many cushions as possible. Remove
storage lids or hatches. Open as many locker
doors, as possible. Open the refrigerator door.
Leave these areas open to improve ventilation.
Make sure that no section of ﬂush hoses is in
contact with moving or hot engine parts or
abrasive 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
Spray the weather covers and the boat upholstery
with Lysol Spray Disinfectant™. Enclosed areas
such as the refrigerator, shower basin, storage
locker areas, etc. should also be sprayed with
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 rodents will destroy upholstery, water
intake and discharge hoses.
The Four Winns installed ﬂush out kit for Volvo
Penta engines is identiﬁed by a transom deck
mounted coupler & cap. This type of ﬂush out
may be used with the boat in or out of the
water and the engine OFF.
If the boat will be in outside storage, properly
support 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 damp-
ness can cause electrical problems, corrosion,
and dry rot.
Volvo Penta’s engine ﬂush out is directly
attached to the engine itself and is identiﬁed
by a blue cap. If the engine comes with this
type of ﬂush out kit installed from Volvo Penta,
follow the procedure included in the engine

Remove cap from coupling and attach water
DO NOT use the bimini top or camper top as a
winter storage cover. The life of these covers may
be signiﬁcantly shortened if exposed to harsh
weather elements for long periods.
Turn water on and allow water to ﬂush the engine
and exhaust manifold for about ten minutes.
Turn water off. Disconnect hose; replace and
tighten cap securely.
Boats stored outside in areas with heavy snow
accumulation are more susceptible to damage,
and should be inspected regularly during the
Reinstall cap onto coupler after ﬂushing for
both types of ﬂush outs. The cap must be
secured after ﬂushing of engine to prevent air
from entering the system and resulting in
possible engine damage.
R - 2 ENGINE FLUSH OUT
The optional engine ﬂush out (if applicable) should be
used to clean the engine of unwanted salt, mud,
sludge, etc. which may have accumulated in the
engine cooling system. Before winterizing the engine,
