SUBMERGED ENGINES

SUBMERGED ENGINES
Once an outboard has been submerged in fresh
or salt water, it must be serviced within three (3)
hours of recovery. Immediate service can mini-
mize the corrosive affect that air has on the pol-
ished surfaces of the crankshaft, connecting rods,
and internal powerhead bearings.
IMPORTANT:
If outboard cannot be started or
serviced immediately, it should be resubmerged in
fresh water to avoid exposure to the atmosphere.
Engine Dropped Overboard
(Not Running)
Disconnect the battery cables at the battery.
Rinse powerhead with clean water.
Remove spark plug leads and spark plugs.
Place outboard in horizontal position (cylinder
heads down). Slowly rotate flywheel in a clock-
wise rotation to work all water out of powerhead.
IMPORTANT:
If sand or silt may have entered
the outboard, DO NOT attempt to start the it. Dis-
assemble and clean.
Disassemble all electrical connectors. Clean con-
nectors and terminals, and treat with water dis-
placing electrical spray. Apply
Electrical Grease to
terminals prior to reassembly. Coat all exposed
solenoid terminals and engine grounds with
Black
Neoprene Dip.
Clean and inspect all electrical components.
Replace damaged or corroded components prior
to returning the outboard to service. Electric start-
ers should be disassembled, cleaned, flushed
with clean water, and treated with water displacing
electrical spray prior to reassembly.
Disconnect fuel supply hose from outboard. Drain
and clean all fuel hoses, filters, and fuel tanks.
Disconnect oil supply hose and oil return hose
from outboard. Drain and clean all oil hoses, fil-
ters, and oil tank assemblies.
Refill fuel tank with fresh fuel and oil tank with rec-
ommended oil.
Prime oil system and fuel system. Refer to
FUEL
AND OIL PRIMING
on p. 51. Make sure all oil
injection hoses are clean and filled with oil.
Make sure high pressure fuel system does not
contain water. Flush as needed.
Inject a small amount of outboard lubricant into
spark plug holes and install new spark plugs.
Refer to Spark Plug
Indexing
on p. 76.
Reinstall all removed or disconnected parts.
Use the Evinrude Diagnostics Software program
to:
•
Initiate Break-in
•
Check fuel pump operation
•
Check injector operation (fuel and oil)
•
Check timing (once outboard is running at full
operating temperature)
Run outboard below 1500 RPM for one-half hour.
Engine Dropped Overboard
(Running)
Follow the same procedures as
Engine Dropped
Overboard (Not Running)
. However, if there is
any binding when the flywheel is rotated, it may
indicate a bent connecting rod and no attempt
should be made to start the outboard. Powerhead
must be disassembled and serviced immediately.
Engine Dropped Overboard
(In Salt Water)
Follow the same procedures used for
Engine
Dropped Overboard (Not Running)
and
Engine
Dropped Overboard (Running)
. Disassemble
and clean outboards that have been submerged in
salt water for prolonged periods of time. Clean or
replace electrical components as necessary.
Prolonged Submersion
(Fresh or Salt Water)
Outboards that have been dropped overboard and
not recovered immediately, must be serviced
within three hours of recovery. Follow the same
procedures used for
Engine Dropped Overboard
(Not Running)
and
Engine Dropped Overboard
(Running)
.
