Operation
motor greatly affects the water resistance. If
the mounting height is too high, cavitation
tends to occur, thus reducing the propulsion
and causing the engine to overheat. If the
mounting height is too low, the water resis-
tance will increase and thereby reduce en-
gine efficiency. Mount the outboard motor so
that the anti-cavitation plate is about 130 mm
could result in reduced engine life or
even severe engine damage.
Premix fuel must be used during break-
in in addition to oil in the oil injection
system.
After break-in, use gasoline only. If pre-
mix fuel is used continuously, the oxy-
gen sensor for the Electronic Fuel
Injection system could be damaged.

Procedure for oil injection models
Run the engine under load (in gear with a
propeller installed) as follows.
1.
First 10 minutes:
Run the engine at the lowest possible
speed. A fast idle in neutral is best.
Next 50 minutes:
2.
130mm
( 5 in.)
Do not exceed half throttle (approxi-
mately 3000 r/min). Vary engine speed
occasionally. If you have an easy-plan-
ing boat, accelerate at full throttle onto
plane, then immediately reduce the
throttle to 3000 r/min or less.

NOTE:
q
The optimum mounting height of the out-
board motor is affected by the boat and
motor combination and the desired use.
Test runs at different heights can help de-
termine the optimum mounting height.
Consult your Yamaha dealer or boat man-
ufacturer for further information on deter-
mining the proper mounting height.
3.
Second hour:
Accelerate at full throttle onto plane,
then reduce engine speed to three-quar-
ter throttle (approximately 4000 r/min).
Vary engine speed occasionally. Run at
full throttle for one minute, then allow
about 10 minutes of operation at three-
quarter throttle or less to let the engine
cool.

the outboard motor, see page 33.

Third through tenth hours:
Your new engine requires a period of break-
in to allow mating surfaces of moving parts to
wear in evenly. Correct break-in will help en-
sure proper performance and longer engine
Avoid operating at full throttle for more
than 5 minutes at a time. Let the engine
