PRE-SEASON SERVICE
PRE-SEASON SERVICE
If outboard was removed from boat for storage,
make certain it has been reinstalled with factory
specified hardware. Refer to
INSTALLATION
AND PREDELIVERY section for proper set-up
procedures.
Clamp Screws and Mounting
Bolts
Check clamp screws and mounting bolts fre-
quently. Grease or replace components as
needed. High use applications require more fre-
quent checks.
Gearcase Lubricant
•
Check the lubricant level.
•
Inspect gearcase for leaks. If leak is apparent,
pressure and vacuum test gearcase.
•
Repair gearcase as needed.
Battery(s)
•
Replace batteries that cannot be properly
charged.
Operational Checks
•
Steering
•
Throttle and shift
•
SystemCheck gauge
•
All other accessories and instrumentation
Fuel System
•
Inspect entire fuel system for leaks prior to start-
ing outboard. Repair all leaks.
•
Start outboard and reinspect.
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 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.
WARNING
Failure to check for fuel leakage could
allow a leak to go undetected, resulting in
fire or explosion.
