WARNING
The outboard motor can be seriously dam-
aged by a collision while operating or
trailering. Damage could make the out-
board motor unsafe to operate.
Trouble Recovery
If the outboard motor hits an object in the wa-
ter, follow the procedure below.
1. Stop the engine immediately.
2. Inspect the control system and all compo-
nents for damage. Also inspect the boat
for damage.
3. Whether damage is found or not, return
to the nearest harbor slowly and careful-
ly.
4. Have a Yamaha dealer inspect the out-
board motor before operating it again.

Running in an emergency (twin en-
gines or triple engines)
Normally use all outboard motors together for
cruising. When using only one or two engines
in an emergency, be sure to keep the unused
engine(s) tilted up and operate the other en-
gine(s) at low speed.
ECM01730
NOTICE
If the boat is operated with only one or two
engines, be sure to tilt the unused en-
gine(s) up. Otherwise water could enter
the exhaust pipe due to the wave action,
causing engine trouble.
TIP:
When maneuvering at low speed, such as
near a dock, it is recommended to tilt the un-
used engine(s) down and to operate the un-
used engine(s) in neutral gear if possible.
