Submerged Engines
Once an outboard has been submerged it must be
serviced within three (3) hours of recovery. Imme-
diate service can minimize the corrosive affect
that air has on the polished surfaces of the crank-
shaft, 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 Submerged (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 it. Disas-
semble and clean.
Disassemble all electrical connectors. Clean con-
nectors and terminals, and treat with water dis-
placing electrical spray. Apply
Dielectric Grease ,
P/N 503243, 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
System Priming on p. 143 and Oil Supply Prim-
ing on p. 171. 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 Plugs on p. 43.
Reinstall all removed or disconnected parts.
Use Evinrude Diagnostics software to:
•
Start break-in oiling
•
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 Submerged (Running)
Follow the same procedures as Engine Sub-
merged (Not Running) . However, if there is any
binding when the flywheel is rotated, it may indi-
cate a bent connecting rod and no attempt should
be made to start the outboard. Powerhead must
be disassembled and serviced immediately.
Engine Submerged (In Salt Water)
Follow the same procedures used for Engine
Submerged (Not Running) and Engine Sub-
merged (Running) . Disassemble and clean out-
boards that have been submerged in salt water for
prolonged periods of time. Clean or replace elec-
trical 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 Submerged (Not
Running) and Engine Submerged (Running) .
