Propulsion System
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.
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.
CAUTION
NEVER RUN AN OUTBOARD MOTOR WITHOUT WATER
FLOWING TO THE WATER PUMP. SERIOUS DAMAGE TO THE
WATER IMPELLER OR ENGINE COULD RESULT.
3.5 Propellers
Propellers convert the engine’s power into thrust.
They come in a variety of styles, diameters and
pitches. All boats powered by Yamaha engines are
equipped with Yamaha propellers. The one that
will best suit the needs of your boat will depend
somewhat on your application and expected av-
erage load. Propeller sizes are identified by two
numbers stamped on the prop in sequence. The
1st number in the sequence (example 14” x 21”) is
the diameter of the propeller and the 2nd number
is the pitch. Pitch is the theoretical distance trav-
eled by the propeller in each revolution.
Always repair or replace a propeller immediately if
it has been damaged. A damaged and therefore
out of balance propeller can cause vibration that
can be felt in the boat and could damage the en-
gine gear assembly. Refer to the engine owner’s
manual for information on propeller removal and
installation.
3.6 Performance Issues and Propellers
It is extremely important that the boat is propped
to run at or very near the recommended top RPM
with an average load. If the top RPM is above or
below the recommend range, the propeller must
be changed to prevent loss of performance and
possible engine damage.
protected. Outboard motors are equipped with
sacrificial anodes to prevent galvanic corrosion
problems. The anodes must be monitored and
replaced as necessary. For locations and mainte-
nance, 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.
CAUTION
DO NOT PAINT THE OUTBOARD MOTOR WITH ANTIFOULING
PAINTS DESIGNED FOR BOAT HULLS. MANY OF THESE PAINTS
CAN CAUSE SEVERE DAMAGE TO THE ENGINE. CONTACT
YOUR EVERGLADES DEALER OR ENGINE MANUFACTURER
FOR INFORMATION ON THE PROPER PAINTING PROCEDURES.
3.3 Engine Lubrication
4-cycle outboard engines incorporate a pressure-
type lubrication system with an oil sump in the
crankcase that must be kept full of the type and
grade of oil recommended by the engine manu-
facturer. It is normal for 4-cycle engines to con-
sume 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.
Notice:
Always monitor the oil level in the crank-
case and only use the type of oil specified by
the engine manufacturer. Yamaha engines
specify Yamalube engine oil.
3.4 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-
