Precautions
WARNING
BE CAREFUL while working on fuel system; gasoline is extremely flammable and
highly explosive under certain conditions. Be sure that ignition key is OFF and do
not smoke or allow sources of spark and/or open flames in the area.
WARNING
To prevent a potential fire hazard, be sure that engine compartment is well
ventilated and that there are no gasoline vapors present during starting or fogging
of engine.
CAUTION
DO NOT operate engine without cooling water being supplied to seawater pickup
pump or water pump impeller will be damaged and subsequent overheating
damage to engine may result.
CAUTION
Seawater (Rawwater) section of cooling system MUST BE COMPLETELY drained
for winter storage, or immediately after cold weather use, if the possibility of freez-
ing temperatures exists. Failure to comply may result in trapped water causing
freeze and/or corrosion damage to engine.
CAUTION
If boat is in the water, seacock (water inlet valve), if equipped, must be left closed
until engine is to be started to prevent water from flowing back into cooling system
and/or boat. If boat is not fitted with a seacock, water inlet hose must be left
disconnected and plugged to prevent water from flowing back into cooling system
and/or boat. As a precautionary measure, attach a tag to the ignition switch or
steering wheel of the boat with the warning: Open seacock or reconnect water inlet
hose before starting engine.
CAUTION
Sterndrive unit should be stored in full DOWN position. Universal Joint bellows may
develop a set if unit is stored in raised position and may fail when unit is returned
to service.
