PROPELLER SELECTION
The performance of your outboard motor
will be critically affected by your choice of
propeller, for an incorrect one could
adversely affect performance and could
seriously damage the motor. The engine
speed depends on the propeller size and
the boat load. If the engine speed is too
high or too low for good engine perfor-
mance, 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 better.

GASOLINE
If knocking or pinging occurs, use a differ-
ent brand of gasoline or premium unlead-
ed fuel.
Recommended gasoline:
Regular unleaded gasoline with a
minimum octane rating of 90
(Research Octane Number)
