Observe these precautions at all times.
Body parts can be crushed between the mo-
Propeller
People can be injured or killed if they come in
contact with the propeller. The propeller can
keep moving even when the motor is in neu-
tral, and sharp edges of the propeller can cut
even when stationary.

ter near you.
 Keep people out of reach of the propeller,
even when the engine is off.

tor and the clamp bracket when the motor is
trimmed or tilted. Keep body parts out of this
area at all times. Be sure no one is in this area
before operating the power tilt mechanism.
The power tilt switches operate even when
the main switch is off. Keep people be away
from the switches whenever working around
the motor.
Never get under the lower unit while it is tilted,
even when the tilt support lever or knob is
locked. Severe injury could occur if the out-
board motor accidentally falls.
Hands, feet, hair, jewelry, clothing, PFD
straps, etc. can become entangled with inter-
nal rotating parts of the engine, resulting in se-
rious injury or death.
Keep the top cowling in place whenever pos-
sible. Do not remove or replace the cowling
with the engine running.
Only operate the engine with the cowling re-
moved according to the specific instructions in
the manual. Keep hands, feet, hair, jewelry,
clothing, PFD straps, etc. away from any ex-
posed moving parts.
Hot parts
Engine shut-off cord (lanyard)
Attach the engine shut-off cord so that the en-
gine stops if the operator falls overboard or
leaves the helm. This prevents the boat from
running away under power and leaving peo-
ple stranded, or running over people or ob-
jects.
Always attach the engine shut-off cord to a
secure place on your clothing or your arm or
leg while operating. Do not remove it to leave
the helm while the boat is moving. Do not at-
tach the cord to clothing that could tear loose,
or route the cord where it could become en-

 Avoid sharp turns or other maneuvers that
make it hard for others to avoid you or un-

Avoid areas with submerged objects or

 Ride within your limits and avoid aggressive
maneuvers to reduce the risk of loss of con-
