Filling engine oil
The outboard motor is shipped from the facto-
ry 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 en-
gine oil before operating the outboard mo-
tor for the first time. Otherwise, the engine
could be damaged severely.

The following sticker, which is affixed to the
outboard motor when it is shipped from the
factory, 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 50.

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 ar-
eas.
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.
