Use only new clean gasoline which has
been stored in clean containers and is not
contaminated with water or foreign matter.
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 main-
tained. 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 appli-
cation.

Gasoline
If knocking or pinging occurs, use a different
brand of gasoline or premium unleaded fuel.
Recommended gasoline:
Regular unleaded gasoline with a
minimum octane rating of 86 (Pump
Octane Number) = (R+M)/2
Gasohol
There are two types of gasohol: gasohol con-
taining ethanol and that containing methanol.
Gasohol containing ethanol can be used if
ethanol content does not exceed 10% and the
fuel meets minimum octane ratings. Yamaha
does not recommended gasohol containing
methanol because it can cause fuel system
damage or engine performance problems.
