Star labels 
Your outboard motor is labeled with a Cali-

bel. See below for a description of yourparticular label. 
EMU25280 
One Star—Low Emission 
The one-star label identifies engines that
meet the Air Resources Board’s 2001 ex-
haust emission standards. Engines meeting
these standards have 75% lower emissions
than conventional carbureted two-stroke en-
gines. These engines are equivalent to the
U.S. EPA’s 2006 standards for marine en-
gines. 
EMU25290 
Two Stars—Very Low Emission 
The two-star label identifies engines that
meet the Air Resources Board’s 2004 ex-
haust emission standards. Engines meeting
these standards have 20% lower emissions
than One Star-Low-Emission engines.

 Safety information 
 
Before mounting or operating the outboard
motor, read this entire manual. Reading it
should give you an understanding of the
motor and its operation. 
 
Before operating the boat, read any own-
er’s or operator’s manuals supplied with it
and all labels. Be sure you understand
each item before operating. 
 
Do not overpower the boat with this out-
board motor. Overpowering the boat could
result in loss of control. The rated power ofthe outboard should be equal to or less
than the rated horsepower capacity of the
boat. If the rated horsepower capacity of
the boat is unknown, consult the dealer or
boat manufacturer. 
 
Do not modify the outboard. Modifications
could make the motor unfit or unsafe to
use. 
 
Incorrect propeller selection and incorrect
use may not only cause engine damage,
but also adversely affect fuel consumption.
Consult your dealer for correct use. 
 
Never operate after drinking alcohol or tak-
ing drugs. About 50% of all boating fatali-
ties involve intoxication. 
 
Have an approved personal flotation de-
vice (PFD) on board for every occupant. It
is a good idea to wear a PFD whenever
boating. At a minimum, children and non-
swimmers should always wear PFDs, and
everyone should wear PFDs when there
are potentially hazardous boating condi-
tions. 
 
Gasoline is highly flammable, and its va-
pors are flammable and explosive. Handle
and store gasoline carefully. Make sure
there are no gas fumes or leaking fuel be-
fore starting the engine. 
 
This product emits exhaust gases which
contain carbon monoxide, a colorless,
odorless gas which may cause brain dam-
age or death when inhaled. Symptoms in-
clude nausea, dizziness, and drowsiness.
Keep cockpit and cabin areas well ventilat-
ed. Avoid blocking exhaust outlets. 
 
Check throttle, shift, and steering for prop-
er operation before starting the engine. 
 
Attach the engine stop switch lanyard cord
to a secure place on your clothing, or your
arm or leg while operating. If you acciden-
tally leave the helm, the cord will pull from

the switch, stopping the engine. 
 
Know the marine laws and regulations
where you will be boating—and obey
them. For basic boating rules, see “Rules
of the road” on page 5. 
 
Stay informed about the weather. Check
weather forecasts before boating. Avoid
boating in hazardous weather. 
 
Tell someone where you are going: leave
a Float Plan with a responsible person. Be
sure to cancel the Float Plan when you re-
turn. 
 
Use common sense and good judgment
when boating. Know your abilities, and be
sure you understand how your boat han-
dles under the different boating conditions
you may encounter. Operate within your
limits, and the limits of your boat. Always
operate at safe speeds, and keep a careful
watch for obstacles and other traffic. 
 
Always watch carefully for swimmers dur-
ing the engine operation. 
 
Stay away from swimming areas. 
 
When a swimmer is in the water near you
shift into neutral and shut off the engine. 
 
Do not illegally discard empty containers
used to replace or replenish oil. For the
correct processing of empty containers,
consult the dealer where you purchased
the oil. 
 
When replacing oils used to lubricate the
product (engine or gear oil), be sure to
wipe away any spilt oil. Never pour oil with-
out using a funnel or similar device. If nec-
essary, verify the necessary replacement
procedure with the dealer. 
 
Never illegally discard (dump) the product.
Yamaha recommends consulting the deal-
er on discarding the product.
