Battery Storage - PCM 2007 5.0L MPI Owner's Operation And Maintenance Manual

8. Remove the large circulating pump hose from
the thermostat housing. Pour the mixture of
antifreeze and water, properly mixed to protect
the engine to the lowest temperatures that it
will be exposed to, into the circulating pump
hose and fi ll the engine block. Pour additional
antifreeze solution into the hoses connected to
the exhaust manifolds.
9. Reinstall the hoses into the thermostat housing
and tighten the hose clamps securely.
After draining is completed, perform the additional
required maintenance as outlined in the MAINTENANCE
SCHEDULE under ONCE EACH YEAR.
DRAINING INSTRUCTIONS
CAUTION
If the boat is to remain in the water during or after
draining, close the seacock to prevent a siphoning
action that may occur, allowing sea water to fl ow from
drain holes or removed hoses.
IMPORTANT: When removing the drain plugs, insert a
wire into the hole to remove any obstruction which would
prevent water from draining completely.
FRESH-WATER COOLED MODELS
IMPORTANT: The fresh-water section of the cooling
system must be kept fi lled year around with
recommended coolant. Make certain that the cooling
system is protected with an ethylene glycol antifreeze
mixture properly mixed to protect the engine to the
lowest temperature that it will be exposed to.
See the ENGINE MAINTENANCE section for testing
alkalinity, draining and refi lling procedures of the Fresh
Water Cooling System, as required.
IMPORTANT: Drain the sea-water section of the cooling
system only.
1. Remove all the drain plugs from the following
locations:
• Heat Exchanger - one on outboard side
• Exhaust Manifolds - remove hoses and/or
drain plugs, one on each side
• Transmission Cooler - one drain plug
• (If Equipped) PCM V-Drive Transmission
- one drain plug.
OUT-OF-SEASON STORAGE - 13
2. Remove the hose from the inlet side of the sea-
water pump.
3. Remove the hose from the outlet side of the sea-
water pump.
NOTICE: It may be necessary to bend or lift the hoses
to allow water to drain completely.
4. Remove the raw water pump impeller. (See
ENGINE MAINTENANCE) If inspection proves
the impeller to be in good condition, store it in
an accessible spot for re-installation at the end
of the storage period. A damaged or badly worn
impeller should be discarded and a new one
installed at the end of the storage period.
NOTE: Removal of the impeller during storage will
prevent the impeller vanes from drying and taking a
permanent "set".
5. After the water has completely drained, coat
the threads of drain plugs with PerfectSeal (or
equivalent), and reinstall in the proper locations.
Reinstall the hoses and tighten all the clamps
securely.
6. Loosen the engine alternator and raw water
pump drive belt(s).
After draining is completed, perform the additional
required maintenance as outlined in the MAINTENANCE
SCHEDULE under ONCE EACH YEAR.

BATTERY STORAGE

Follow the battery manufacturer's instructions for
storage. If not available, use the following instructions:
• Remove the battery from the boat and clean,
removing dirt and grease from the top of the
battery.
• Fill the battery with distilled water to the
manufacturer's specifi cations.
• Store the battery in a cool, dry place. Do not
store on a concrete surface.
• Periodically (every 30 to 45 days), check the
water level and recharge the battery to the
manufacturer's specifi cations. Do not fast
charge.
A discharged battery can be damaged by freezing.
