CAUTION

Do not leave the engine's old lubricating oil in the sump over the lay-up period. Lubricating

oil and combustion deposits combine to produce harmful chemicals which can reduce the

life

your engine's internal parts.

Fuel

System

Top off your fuel tanks with

No.2

diesel fuel. Fuel additives should be added

this time to control algae

and condition the fuel. Care should be taken that the additives used are compatible with the primary fil-

ter/water separator used in the system. Change the element in your primary fuel filter/Water separator, if the

fuel system contains one, and clean the separator sediment bowl.

Change the fuel filter elements on the engine and bleed the fuel system, as needed.

Start the engine and

allow it

run for 5 -

minutes

ensure that no air is left

the fuel system. Check

for

any leaks that may

have been created in the fuel system during this servicing, correcting them as needed.

Sea Water

Circuit

Close the through-hull sea cock. Remove the sea water intake hose from the sea cock. Place the end

this hose into a 5-gallon bucket

clean fresh water. Before starting the engine, check the zinc anode found

in the primary heat exchanger on the engine and clean

replace it as required. Clean the sea strainer,

one

installed in the inside

the hull.

Start the engine and allow the sea water pump to draw fresh water through the system. When the bucket

empty, stop the engine and refill the bucket with

antifreeze solution slightly stronger than needed for winter

freeze protection in

your

area.

Start the engine and allow all of this mixture to be drawn through the sea water system. Once the bucket

empty, stop the engine. This antifreeze mixture should protect the sea water circuit from freezing during the

winter lay-up, as well as providing corrosion protection.

Remove the Impeller from your sea water pump (some antifreeze mixture will accompany

it,

so catch it in a

bUCket).

Examine the impeller. Acquire a replacement,

needed, along with a cover gasket. Do not replace

the impeller (into the pump) until recommissioning, but replace the cover and gasket.

Intake

Manifold

and

Through-Hull

Exhaust

Place a clean cloth, lightly soaked

lubricating oil, in the opening

the intake manifold

block the open-

ing. Do not shove the cloth out

sight. (If it is not visible at recommissioning, and an attempt

made

start the engine, you may need the assistance

a servicing dealer.) Make a note

remove the cloth prior

to start-up. The through-hull exhaust part can be blocked in the same manner.

Starter

Motor

Lubrication and cleaning

the starter drive pinion is advisable, if access

the starter permits its easy

removal. Ensure that the battery connections are shut off before attempting

remove the starter. Take care

in properly replacing any electrical connections removed from the starter.
