Filling engine oil

The outboard motor is shipped from the fac-
tory without engine oil. If your Yamaha dealer
did not fill the engine with engine oil, you
must fill the engine before starting it.
NOTICE: Make sure that the engine is filled
with engine oil before operating the out-
board motor for the first time. Otherwise,
the engine could be damaged severely.
[ECM02241]
The following tag, which is fitted on the out-
board motor when it is shipped from the fac-
tory, should be removed after the engine is
filled with engine oil for the first time. For
more information on checking the engine oil
level, see page 52.

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.

Procedure for breaking in engine
Your new engine requires a period of 10
hours break-in so that mating surfaces of
moving parts wear in evenly.
Operate the engine in the water under load (in
gear with a propeller installed) for 10 hours as
follows. When breaking in the engine, avoid
extended idling, rough water, and crowded
areas.
1. For the 1st hour of operation:
Operate the engine at varying speeds up
to 2000 r/min or approximately 1/2 throt-
tle.
2. For the 2nd hour of operation:
Increase the engine speed until the boat
is on plane (but avoid full-throttle opera-
tion), and then back off on the throttle
while keeping the boat at a planing
speed.
3. For the remaining 8 hours of operation:
Operate the engine at any speed. How-
ever, avoid operating at full throttle for
more than 5 minutes at a time.
4. After the 1st 10 hours of operation:
Operate the engine normally.
