CAUTION
!
DO NOT use copper-based coatings
or any coatings not approved for use
with aluminum. Some paint manufac-
turers claim their paints are safe for
aluminum. Copper components and
copper-based paints can cause severe
corrosion to aluminum. DO NOT use
copper-based paints. Mercury or mer-
cury-based compounds that come
into contact with aluminum will result
in severe corrosion.
1.3 Engine Lubrication
4-cycle engines have an oil sump in the
crankcase. The oil type, grade and level must
be followed in accordance with the engine
manufacturer’s recommendation. It is nor-
mal for 4-cycle engines to consume a small
amount of oil. Check the oil level before each
use and change it following the engine man-
ufacturer’s recommendation.
2-cycle outboard engines are lubricated by
an oil injection system. Check the oil level
before each use and use only type specified
by the engine manufacturer. Also monitor the
oil level by checking the gauge in the helm
or visually checking the oil level in the tank
by using the reference marks on the tanks.
Refer to the engine owner’s manual for oil
specifications and additional information on
the oil injection system. Refer to the Fuel
System Section.
NOTICE
!
Use only the oil recommended by the
engine manufacturer, and monitor the
oil level. Use of any other type of oil
can cause the engine to malfunction
or severe damage.
1.4 Engine Cooling System
Outboard engines are raw water (sea water)
cooled. Water is pumped through the water
inlets, circulated through the engine block,
and expelled with the exhaust through
exhaust port, water port and the propeller
hub. The water pump uses a small impeller
made of synthetic rubber. The impeller and
water pump cannot run dry for more than
a few seconds. In most outboard engines,
some cooling water is diverted through ports
below the engine cowling. This allows the
operator to visually check the operation of the
cooling system. When the engine is started,
make sure a steady stream of water is pres-
ent.
CAUTION
!
DO NOT operate an engine out of the
water, even momentarily. Water must
be supplied to the cooling system
of the power head and water pump,
or serious damage will result. If it is
necessary to run the engine out of
the water, connect it to a engine flush
attachment design for your specific
engine.
If the boat is used in salt or badly polluted
water, flush the engines after each use to
reduce corrosion. Refer to the engine own-
er’s manual for the proper engine flushing
procedure.
