PROPELLER SELECTION
The  performance  of  your  outboard  motor
will  be critically  affected  by your  choice  of
propeller,   as   an   incorrect   choice   could
adversely   affect   performance   and  could
also  seriously  damage  the  motor.  Engine
speed  depends  on  the propeller  size  and
boat load. If engine speed  is too high or too
low  for good  engine  performance, this  will
have an adverse effect on the engine.
Yamaha outboard motors are fitted with pro-
pellers chosen to  perform well over a range
of   applications,  but   there  may   be   uses
where  a   propeller   with  a   different  pitch
would  be  more appropriate.  For  a  greater
operating  load, a  smaller-pitch  propeller is
more   suitable  as   it  enables   the   correct
engine speed to be  maintained. Conversely,
a larger-pitch propeller is more suitable for a
smaller operating load.
Yamaha dealers stock a range of propellers,
and can  advise  you and  install a  propeller
on your outboard  that is best  suited to your
application.
NOTE:
At  full throttle  and under  a  maximum boat
load, the  engines rpm should  be within the
upper   half  of   the   full   throttle   operating
range,  as  listed  in SPECIFICATIONS”  on
page  4-1.  Select  a  propeller  which  fulfills
this requirement.
If  operating  under  conditions  which  allow
the  engines  rpm  to  rise  above  the maxi-
mum  recommended  range  (such   as  light
boat  loads),  reduce  the  throttle  setting  to
maintain  the  rpm  in  the  proper  operating
range.
