Engine Flush Out - Four winns 338 Vista Owner's Manual

C. Prior to Winter Storage
1. Remove as many cushions as possible. Re move
storage lids or hatches. Open as many locker
doors, as possible. Open the refrigerator door.
Leave these areas open to improve ventilation.
2. Spray the weather covers and the boat uphol stery
with Lysol Spray Disinfectant™. En closed areas
such as the refrigerator, shower basin, storage
locker areas, etc. 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 rodents will destroy uphol stery, water
intake and discharge hoses.
4. 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.
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.
5. DO NOT use the bimini top or camper top as a
winter storage cover. The life of these covers may
be signifi cantly shortened if ex posed to harsh
weather elements for long periods.
NOTICE
Boats stored outside in areas with heavy snow
accumulation are more susceptible to damage,
and should be inspected regularly during the
winter months.

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,
flush out the system for about ten minutes.
General Maintenance - Section R
A. Volvo Penta Engine Flush Out
®
(Four Winns Installation)
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. Dam age to the hoses could cause
leaks and possible flooding of the engine
compartment. Periodically check hoses for
abrasions.
NOTICE
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.
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
operator's manual only.
To flush out the engine with Four Winns installed
flush out kit, follow the instructions below:
1. Do not run engine during flushing procedure.
2. Remove cap from coupling and attach water
supply hose.
3. Turn water on and allow water to flush the engine
and exhaust manifold for about ten minutes.
4. Turn water off. Disconnect hose; replace and
tighten cap securely.
Rein stall cap onto cou pler after fl ush ing 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.
