antifreeze solution. Start engine and
run 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
prevent antifreeze
crystallizing in sea strainer, which
warranty will not cover.
5. Loosen water pump and alternator
belts to lessen tension on belts
during winter.
6. For engines equipped with a hand
crank: pull compression
levers 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
upper cylinder during layup.
8. Scrape all rust or corrosion from
exposed metal parts and surfaces.
Scrub all metal
detergent 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
from
release
surfaces with
not charge battery near any open
flame or a confined area.
CAUTION: Wear safety goggles
and rubber gloves to protect your
skin.

2. Close seacock, remove raw water
pickup hose from water pump, attach
4-foot (1.2m) length of hose to water
pump and immerse

solution. 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
thermostat opens.
Replace hose that leads to exhaust
elbow. Star engine and let run till
water comes out exhaust pipe. Stop
engine, remove hose from water
pump to bucket, attach hose from
seacock to water pump and tighten
all hose clamps.
