STORAGE/WINTERIZATION
until antifreeze solution comes out
exhaust stack or until bucket is
empty. Attach the raw water pickup
hose to the raw water pump. Tighten
all clamps. NOTE: This procedure
bypasses the sea strainer to pre-
vent antifreeze from crystallizing
in sea strainer, which warranty
will not cover.
5. Loosen water pump and alternator
belts to lessen tension on belts dur-
ing winter.
6. For engines equipped with a hand
crank: pull compression release lev-
ers and turn engine slowly with the
hand crank. Slowly pour about 2
ounces of engine oil into the intake
pipe or manifold while hand cranking
the engine. This will allow for a thin
coat of oil on the valves and upper
cylinder. DO NOT USE starter to turn
engine or serious engine damage
may result.
7. Tape the openings of the intake
and exhaust manifolds with duct tape
to help prevent corrosion of the up-
per cylinder during layup.
8. Scrape all rust or corrosion from
exposed metal parts and surfaces.
Scrub all metal surfaces with deter-
gent and rinse thoroughly. Paint any
bare metal.
9. Place a dust cover over engine.
Do not leave the engine exposed to
rain and sea breeze.
10. Disconnect the battery cables;
remove the battery from the boat.
Clean the terminal ends and battery
with a solution of baking soda and
water, and then rinse thoroughly with
clean water. Apply a light coat of
grease on the terminal end of the
battery and cables. Store the battery
in a cool dry place. Use a trickle
charger to keep battery charged. Do
not charge battery near any open
flame or a confined area.
CAUTION: Wear safety goggles
and rubber gloves to protect your
skin.
Winterizing Raw Water Cooled
Diesel Engines
1. Drain crankcase and transmission
and refill with fresh oil as specified in
the engine manual. Change oil fil-
ters.
2. Close seacock, remove raw water
pickup hose from water pump, attach
4-foot (1.2m) length of hose to water
pump and immerse in a 5 gal-
lon(19L) bucket of anti freeze solu-
tion. Remove hose from engine or
manifold that leads to exhaust elbow.
Attach about a 4-foot length of hose
and immerse one end in the bucket
of antifreeze solution. Start engine
and run until water begins to warm
up (about 3-5 min.) and the thermo-
stat opens. Stop engine. Replace
hose that leads to exhaust elbow.
Star engine and let run till water
comes out exhaust pipe. Stop en-
gine, remove hose from water pump
to bucket, attach hose from seacock
to water pump and tighten all hose
clamps. NOTE: this procedure by-
passes the sea strainer to prevent
antifreeze from crystallizing sea
strainer, which warranty will not
cover.
3. Loosen water pump and alternator
to lessen tensions on belts during
winter.
4. Drain and clean all fuel filters and
change elements, gaskets and seals.
Bleed all air from fuel systems.
5.Pull compression release lever and
turn engine slowly with hand crank.
Slowly pour about 2 ounces of
