1.3 Engine Lubrication
Four-cycle engines have an oil sump in the
crankcase. Use the oil type, grade, and level
recommended by the engine manufacturer.
It is normal for 4-cycle engines to consume a
small amount of oil. Check the oil level before
each use and change it following the engine
manufacturer’s recommendation.
Two-cycle outboard engines are lubricated
by an oil injection system. Check the oil
level before each use and use only the type
specified by the engine manufacturer. Also
monitor the oil level by checking the gauge
on the helm or visually checking the oil level
in the tank by using the reference marks on
the tanks. Refer to section 3, Fuel Systems,
and the engine owner’s manual for oil speci-
fications and additional information on the oil
injection system.
NOTICE
!
Use only the oil recommended by the
engine manufacturer, and monitor the
oil level. Use of any other type of oil
can cause severe damage or engine
malfunction.
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 the
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 present.
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.
1.5 Propellers
The propellers convert the power of the
engines into thrust. Propellers vary in style,
diameters and pitch. The best set for your
needs will depend on your application and
expected average load. Propeller sizes are
identified by two numbers stamped on the
prop in sequence; the first is the diameter and
the second is the pitch (example 14 x 21).
Pitch is the theoretical distance the propeller
will travel in one rotation.
Repair or replace a propeller immediately if it
has been damaged. A damaged propeller can
cause vibration that can be felt in the boat
and can damage the engine gear case. Refer
to the engine owner’s manual for information
on propeller removal and installation.
1.6 Engine Instrumentation
The hardtop pod in the helm area is equipped
with a single Yamaha multi-function display
(MFD). The MFD allows the operator to mon-
itor all engine functions (including fuel level
and engine trim), operate the engines most
efficiently, and pr event serious costly dam-
age. The instrumentation is unique to the type
