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 crankcase
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-
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 Outboard Flushing System
Your boat is equipped with an automatic outboard
flushing system that allows you to flush all four
engines in sequence from one hose connection.
The following is an overview of the flushing process.
Your boat may be slightly different, depending on
the flush system, engine selection and other equip -
ment selected. Always refer to the flush system
operation manual for specific instructions for the
system installed.
To flush the engines:
1. Shutdown the engines.
2. Connect a shore side freshwater hose to the
connection in the cockpit and turn on the water.
3. Press the start button to select the desired flush
time and start the sequential flushing process.
4. The system flushes the first motor for the se -
lected time, then automatically moves to the
next.
5. The system automatically shuts off once all
motors are flushed.
3.6 Propellers
The propellers convert the engine’s power into
thrust. They come in a variety of styles, diam-
eters and pitches. All boats powered by Yamaha
engines are equipped with Yamaha propellers. The
propellers that will best suit the needs of your boat
will depend somewhat on your application and ex-
pected average load. Propeller sizes are identified
