Maintenance

TIP:
The use of “Yamalube Fuel Stabilizer & Con-
ditioner Plus” eliminates the need to drain the
fuel system. Consult your Yamaha dealer or
other qualified mechanic if the fuel system is
to be drained instead.
3.
Remove the top cowling and propeller.
4.
Install the flushing attachment over the
cooling water inlet.
NOTICE:
Do not run
the engine without supplying it with
cooling water. Either the engine water
pump will be damaged or the engine
will be damaged from overheating.
Before starting the engine, be sure to
supply water to the cooling water pas-
sages. Avoid running the outboard
motor at high speed while on the
flushing attachment, otherwise over-
heating could occur.

5.
Cooling system flushing is essential to
prevent the cooling system from clog-
ging up with salt, sand, or dirt. In addi-
tion, fogging/lubricating of the engine is
mandatory to prevent excessive engine
damage due to rust. Perform the flushing
and fogging at the same time.
WARNING! Do not touch or remove
electrical parts when starting or dur-
ing operation. Keep hands, hair, and
clothes away from the flywheel and
other rotating parts while the engine is
running.
[EWM00092]
TIP:
When using the flushing attachment, main-
tain adequate water pressure so that there
is a steady flow of water from the cooling
water pilot hole.
If the overheat alert device is activated, turn
the engine off, and consult your Yamaha
dealer.
6.
Run the engine at a fast idle for a few
minutes in neutral position while supply-
ing fresh water.
7.
Just prior to turning off the engine, quick-
ly spray “Yamaha Stor-Rite Engine Fog-
ging Oil” alternately into the intake
silencer or the fogging hole of the silenc-
er cover, if equipped. When properly do-
ne, the engine will smoke excessively
and almost stall.
8.
Remove the flushing attachment and
wipe off any excess water.
9.
Install the top cowling and propeller.
10. Drain the cooling water completely out of
the motor. Clean the body thoroughly.
TIP:
A flushing attachment is available from your
Yamaha dealer.
