able containers
and
dispose
of
it according
to local regulations. Make sure to wipe up
any spills
and
cover any containers
of
anti-
freeze. Keep antifreeze out
of
the reach
of
children
and
animals.
3. Open the drain on the underside
of
the exhaust mani-
fold
(Figure
1).
4. Open the drain on the engine block
(Figure
2, typical).
5. Allow the freshwater section to drain completely.
6. On models equipped with a remote reservoir, discon-
nect the hose to the engine and drain the coolant from the
reservoir. Reconnect the hose.
7. Close the drain plugs.
8.
If
refilling the freshwater section, refer to Chapter
Three for the filling procedure.
Seawater cooling section
Refer to the following procedure to drain the seawater
section.
1. Place a suitable containerunder the drain,
if
space per-
mits. This will preventwaterfrom draining into the bilge.
NOTE
If
no waterflows from the drain, check the
drain to make sure it is not obstructed or
plugged.
2. Open the drain on the underside
of
the exhaust mani-
fold end cap
(Figure
2).
3. Allow the water to drain completely, then close the
drain.
4. Loosen the cover screws on the seawater
pump
(Fig-
ure
3) and drain any water in the pump.
If
the gasket is
damaged, remove the cover and install a new gasket and
the cover.
5. Remove the lower end
of
the cooling system hoses
from the pump and exhaust manifold. Lower the hoses
and allow them to completely drain. Then reconnect the
hoses and clamp securely.
NOTE
It is possible that undrained water may re-
main. Protect the seawater cooling section
byfilling it with an antifreeze solution.
FITTING
OUT
Preparing the boat for use after storage is easier
if
the
engine was properly prepared before storage. Refer to the
list
of
needed work that was to be performed before re-
turning the engine to service.
If
there is other work to be
CHAPTER

done, determine
if
the work is easier, and possibly more
economical,
if
performed before returning the engine to
service.
1. Remove all covers placedoverengine openings during
lay-up.
2.
If
the seawater cooling system is filled with an anti-
freeze solution, drain the antifreeze from the system using
the draining procedure described for the seawatercooling
system or the procedure for the seawater section
if
equipped with a freshwater (closed) cooling system.
3.
If
left loose during lay-up, tighten the seawater pump
cover screws
(Figure
3).
4. Adjust belt tension for the water pump and alternator
drive belts as described in Chapter Three.
5. Replace all fuel filters.
6.
If
equipped with a fuel tank drain valve, open the drain
valve and remove any water that may have accumulated in
the tank.
WARNING
Be sure to have a Coast Guard-approved
fire extinguisher on hand whenever working
aroundfuel.
NOTE
If
the
fuel
in the
fuel
tank is dirty, old or con-
taminated with water, drain or
pump
out the
fuel. Clean the tank and refill with fresh,
clean fuel. Although
fuel
filters will remove
most contaminants, excessively dirty
fuel
may clog the filters or enter the engine,
causing damage.
7. Bleed the fuel system as described in Chapter Seven.
8. Checkthe battery electrolyte level and fill
if
necessary.
Make certain the battery has a full charge; recharge
if
nec-
essary. Clean the battery terminals and install the battery,
making sure the cables are connected properly. Cover the
battery terminals with a light coat
of
petroleum jelly.
9. Check the crankcase oil level. Add oil,
if
necessary.
If
the oil was not changed at time
of
lay-up or
if
the engine
has been in storage for an extended period
oftime,
change
the oil and oil filter.
10. Move the engine control to the STOP position. Posi-
tion the decompression lever in the ON position. Engage
the starter and crank the engine for 30 seconds. This pro-
cedure will pump engine oil to the engine bearings and
other engine parts.
11. On engines equipped with a freshwater cooling sys-
tem, check the coolant.
If
the coolant is contaminated or
has reached its scheduled replacement time, drain, flush
and refill the freshwater cooling system.
