EMU29433

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.

EMU29462

Replacing fuse

If the fuse has blown on an electric start
model, open the fuse holder and replace the
fuse with a new one of the proper amperage.

WARNING

EWM00630

Be sure to use the specified fuse. An in-
correct fuse or a piece of wire could allow
excessive current flow. This could cause

electric system damage and a fire hazard.
