Next to selecting an  outboard, choosing the
right propeller  is one  of the most  important
purchasing  decisions  a  boater  can  make.
The type, size, and  design of your propeller
have  a  direct  impact  on  acceleration,  top
speed, fuel  economy, and even engine  life.
Yamaha designs  and manufactures propel-
lers for  every Yamaha  outboard motor  and
every application.
Your outboard  motor came  with a  Yamaha
propeller  chosen   to  perform  well   over  a
range of applications, but there may be uses
where  a different  propeller would  be  more
appropriate.

Start-in-gear protection
Yamaha  outboard  motors  or   Yamaha-ap-
proved  remote  control  units  are  equipped
with start-in-gear  protection  device(s). This
feature permits the engine to be started only
when it  is in  neutral.  Always select  neutral
before starting the engine.

Engine oil requirements
Recommended engine oil:
YAMALUBE 2-stroke outboard motor
oil
Your Yamaha dealer can help you select the
right propeller for your boating needs. Select
a propeller that will allow the engine to reach
the  middle  or  upper  half  of the  operating
range at full throttle with the maximum boat-
load. Generally, chose a larger pitch propel-
ler for a smaller operating load and a smaller
pitch propeller for a heavier load. If you carry
loads that  vary  widely, chose  the propeller
that lets the  engine run in  the proper range
for your  maximum  load but  remember that
you may need to reduce your throttle setting
to  stay   within   the  recommended   engine
speed range when carrying lighter loads.
If the  recommended engine oil  is not  avail-
able,  another  2-stroke  engine  oil  with  an
NMMA-certified TC-W3 rating may be used.

Gasoline
Use a  good quality gasoline  that meets the
minimum octane rating.  If knocking or ping-
ing occurs, use a different brand of gasoline
or   premium  unleaded   fuel.   Yamaha   re-
