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
propellers 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   main-
tained.   Conversely,   a  larger-pitch   pro-
peller is more suitable  for a smaller oper-
ating load.
Yamaha  dealers   stock  a  range  of   pro-
pellers, and  can advise  you and  install a
propeller  on  your  outboard  that  is best
suited to your application.
