FUEL FILLER CAP
The fuel gauge is part of the fuel cap.

Gasoline is
extremely
flammable,
and gaso-
line vapor can explode, causing
serious injury or death. Do not
smoke or allow flames or sparks
in your working
area. KEEP
OUT OF REACH OF CHILDREN.
Over-Rev Limiter
This outboard motor is equipped with
an engine over-rev limiter which limits
the maximum engine rpm. This over-
rev limiter protects the engine from
mechanical damage.
The over-rev limiter may be activated
by putting the propeller in a light load
condition or propeller ventilation.
When the over-rev limiter is activated
the engine rpm will become unstable
or erratic. Should this occur reduce the
throttle opening and wait for the engine
rpm to stabilize then slowly increase the
throttle opening.
On the power trim/tilt type motors lower
the trim angle on high speed turns to re-
duce the possibility of propeller ventila-
tion.
