EMU29432

Temporary action in

emergency

EMU29440

Impact damage

WARNING

EWM00870

The outboard motor can be seriously

damaged by a collision while operating or
trailering. Damage could make the out-

board motor unsafe to operate.

If the outboard motor hits an object in the wa-
ter, follow the procedure below.

Stop the engine immediately.

Inspect the control system and all com-
ponents for damage. Also inspect the
boat for damage.

Whether damage is found or not, return
to the nearest harbor slowly and careful-
ly.

Have a Yamaha dealer inspect the out-
board motor before operating it again.

EMU29450

Running single engine

When using only engine in an emergency, be
sure to keep the unused one tilted up and op-
erate the other engine at low speed.

CAUTION:

ECM00370

If the boat is operated with one engine in
the water but not running, water may run
into the exhaust pipe due to wave action,

causing engine trouble.

NOTE:

When you are maneuvering at low speed,
such as near a dock, it is recommended that
both engines be running with one in neutral

gear if possible.
