CAUTION
CAUTION
Galvanic corrosion is the corrosion process oc-
curring when different metals are submerged in
an electrolyte. Seawater is an electrolyte and
submerged engine components must be prop-
erly protected. Outboard motors are equipped
with sacrificial anodes to prevent galvanic corro-
sion problems. The anodes must be monitored
and replaced as necessary. For locations and
maintenance, please refer to the engine owner’s
manual.
When leaving the boat in the water, tilt the mo-
tors as high as possible. This will decrease the
risk of marine growth around the cooling inlets,
propeller and exhaust ports and damage from
galvanic corrosion.
DO NOT PAINT AN OUTBOARD MOTOR WITH ANTIFOULING
PAINTS DESIGNED FOR BOAT HULLS. MANY OF THESE PAINTS
CAN CAUSE SEVERE DAMAGE TO THE ENGINE. CONTACT
YOUR SCOUT DEALER OR ENGINE MANUFACTURER FOR
INFORMATION ON THE PROPER PAINTING PROCEDURES.
1.3 Engine Lubrication
2-cycle outboard motors are lubricated by a vari-
able ratio oil injection system. The oil tank is
mounted below the cockpit floor near the transom.
Always monitor the oil level before each cruise
by checking the gauge or indicator lights in the
helm (not available on all engine installations) or
visually checking the oil level using the reference
marks on the tank.
When additional oil is needed, use only the type
of oil specified by the engine manufacturer. Refer
to the engine owner’s manual for oil specifications
and additional information on the oil injection
system.
Notice:
Always monitor the oil level in the tank and
only use the type of oil specified by the en -
gine manufacturer. Yamaha engines specify
Yamalube engine oil.
4-cycle outboard engines have an oil sump in the
crankcase that must be kept full of the type and
grade of oil recommended by the engine manufac-
turer. It is normal for 4-cycle engines to consume
a small amount of oil. Therefore, the oil must be
checked before each use and changed at regular
intervals as instructed by the engine owner’s
manual. As with 2-cycle engines, use only the
type of oil specified by the engine manufacturer.
1.4 Engine Cooling System
Outboard engines are raw water (seawater)
cooled. Water is pumped through the water
inlets, circulated through the engine block, and
relinquished with the exhaust gases through 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 motors, some
cooling water is diverted through ports below the
engine cowling. This allows the operator to visu-
ally check the operation of the cooling system.
When the engine is started, always check for a
steady stream of water coming out of those ports.
NEVER RUN AN OUTBOARD MOTOR WITHOUT WATER
FLOWING TO THE WATER PUMP. SERIOUS DAMAGE TO THE
WATER IMPELLER OR ENGINE COULD RESULT.
Notice:
If the boat is used in salt or badly polluted
water, the engines should be flushed after
each use. Refer to the engine owner’s man-
ual for the proper engine flushing procedure.
