Draining Instructions - PCM 2006 5.0L MPI Owner's Operation And Maintenance Manual

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.
RAW-WATER COOLED MODELS
1. Remove all the drain plugs from the following
locations:
• Cylinder Block - one on each side (5.0/5.7L
engines, remove the knock sensor on the
port side). When installing the knock sensor,
torque to 20 N . m (15 lb ft).
• 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.
2. Remove the hose from the inlet side of the sea-
water pump.
3. Remove the large hose from the engine
circulating pump, or drain plug (if equipped).
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 the drain plugs with PerfectSeal (or
equivalent), and reinstall in the proper locations.
Reinstall all the hoses and tighten the clamps
securely.

6. Loosen the engine alternator and raw water
pump drive belt(s).
NOTICE: For additional protection against freezing and
corrosion, you may wish to fi ll the engine with antifreeze.
If ethylene glycol based antifreeze is used, check with
local environmental agencies about the proper disposal
of antifreeze. It may be necessary to drain the system
prior to re-commissioning the boat.
7. Remove the hoses which connect to the exhaust
manifolds from the thermostat housing.
