NOTICE : DANGER/WARNING/CAUTION/Note
Before installing, operating or otherwise handling your outboard motor, be sure to thor-
oughly read and understand thisOwner'sManual and carefully follow all of the instruc-
tions. Of particular importance isinformation preceded by the words"DANGER,"
"WARNING," "CAUTION," and "Note." Alwayspay special attention to such information to
ensure safe operation of the outboard motor at all times.
Failure to observe will result in severe personal injury or death, and possibly property dam-
age.
Failure to observe could result in severe personal injury or death, or property damage.
Failure to observe could result in personal injury or property damage.
Note
Thisinstruction providesspecial information to facilitate the use or maintenance of the outboard
motor or to clarify important points.
EMERGENCY STOP SWITCH
The Emergency Stop Switch will stall the outboard motor when the stop switch tether is
pulled off. Thisstop switch tether can be attached to the operator of the outboard motor
to minimize or prevent injuriesfrom the propeller in case the operator fallsoverboard.
We highly recommend use of the Emergency Stop Switch tether.
Accidental activation of the Emergency Stop Switch (such as the tether being pulled out in
heavy seas) could cause passengers to lose their balance and even fall overboard, or it
could result in loss of power in heavy seas, strong currents, or high winds. Loss of control
while mooring is another potential hazard.
To minimize accidental activation of the Emergency Stop Switch, the 500 mm (20 inch.) stop
switch tether is coiled and can extended to a full 1,300 mm (51 inch.).
