First-time operation

Breaking in engine

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
life. 

NOTICE:

 Failure to follow the break-in

procedure could result in reduced engine
life or even severe engine damage.

Gasoline and engine oil mixing chart (25:1)

NOTICE

ECM00151

Be sure to mix gasoline and oil completely,
otherwise the engine may be damaged.

EMU27075

Procedure for pre-mixed models

Run the engine under load (in gear with a pro-
peller installed) for 10 hours as follows.
1.

First 10 minutes:
Run the engine at the lowest possible
speed. A fast idle in neutral is best.

2.

Next 50 minutes:
Do not exceed half throttle (approxi-
mately 3000 r/min). Vary engine speed
occasionally. If you have an easy-planing
boat, accelerate at full throttle onto
plane, then immediately reduce the
throttle to 3000 r/min or less.

3.

Next two hours:
Accelerate at full throttle onto plane, then
reduce engine speed to three-quarter
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.

4.

Remaining seven hours:
Run the engine at any speed. However,
avoid operating at full throttle for more
than 5 minutes at a time.

5.

After the first 10 hours:
Operate the engine normally. Use the
standard premix ratio of gasoline and oil.
For details on mixing fuel and oil, see
page 21.

EMU36402

Getting to know your boat

All boats have unique handling characteris-
tics. Operate cautiously while you learn how
your boat handles under different conditions
and various trim angles (see page 27).

EMU36414

Checks before starting engine

WARNING

EWM01922

If any item in “Checks before starting en-
gine” is not working properly, have it in-
spected and repaired before operating the
outboard motor. Otherwise, an accident
could occur.

NOTICE

ECM00121

Do not start the engine out of water. Over-
heating and serious engine damage can
occur.

EMU37142

Fuel level

Be sure you have plenty of fuel for your trip. A
good rule is to use 1/3 of your fuel to get to
the destination, 1/3 to return, and to keep 1/3

: Gasoline

2.

: Engine oil
