Section 02 MAINTENANCE
Subsection 03 (WATER-FLOODED ENGINE)
If it was submerged in salt water, spray bilge and
all components with fresh water using a garden
hose to stop the salt corroding effect.
CAUTION: Never try to crank or start the en-
gine. Water trapped in the intake manifold
would enter the combustion chamber through
the intake valves and may cause damage to
the engine.
Whenever the engine is stopped, all the valves
close thus preventing water from being ingested
in the engine.
Supercharged 4-TEC Engines
Inlet duct should be disconnected from super-
charger inlet tube to validate presence of water.

1. Inlet duct
2. Inlet hose
3. Outlet hose
If water is suspected to be in the supercharger,
remove its outlet hose and siphon water out. En-
sure that siphon tube is inserted to the lowest
point in the supercharger.
NOTE: Keep outlet hose disconnected and contin-
ue procedures below. This way, when engine will
be started, possible water trapped in supercharger
will be pushed out. Then, the hose can be recon-
nected.
If necessary, remove supercharger housing.
All 4-TEC Engines
If water is suspected to be in the intake and the
exhaust system, it must be drained as follows:
Remove the intake manifold and drain it. Then
suck out the water from the intake valve ports.
Refer to subsection INTAKE SYSTEM.
Remove the water from oil/air separator breather
hose.
Remove the exhaust pipe and drain it. Then either
remove the mufflers to drain them or siphon the
water out of them. Refer to subsection EXHAUST
SYSTEM.
If water gets in the oil (oil will be milky), change
the engine oil and filter as follows.
Oil Change Procedure
(water-contaminated oil)
– Using the oil VAC (P/N 529 035 880), siphon oil
from reservoir through dipstick hole.
CAUTION: Never crank or start engine when
siphon tube is in dipstick hole. Never start en-
gine when there is no oil in engine.
– Remove the oil vac tool from the dipstick hole.
– While in drowned engine mode, crank the en-
gine for 5 seconds.
– Remove the oil filter cap and the oil filter.
– Again, siphon oil from the reservoir.
– Put a rag under the scavenge oil pump cover.
– Remove the scavenge oil pump cover drain plug
and install a fitting (P/N 293 710 037).
