be critically affected by your choice of propel-
ler, 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.

CAUTION:
Use only new clean gasoline which has
been stored in clean containers and is not
contaminated with water or foreign mat-
ter.
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 suit-
able as it enables the correct engine speed
to be maintained. Conversely, a larger-pitch
propeller is more suitable for a smaller oper-
ating load.

Gasoline
If knocking or pinging occurs, use a different
brand of gasoline or premium unleaded fuel.
Recommended gasoline:
Regular unleaded gasoline with a min-
imum octane rating of 86 (Pump Oc-
tane Number) = (R+M)/2
Gasohol
Yamaha dealers stock a range of propellers,
and can advise you and install a propeller on
your outboard that is best suited to your ap-
plication.
There are two types of gasohol: gasohol con-
taining ethanol and that containing metha-
nol. 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.
