Replacement parts
If replacement parts are necessary, use only
genuine Yamaha parts or parts of equivalent
design and quality. Any part of inferior quality
may malfunction, and the resulting loss of
control could endanger the operator and pas-
sengers. Yamaha genuine parts and acces-
sories are available from your Yamaha
dealer.

Severe operating conditions
Severe operating conditions involve one or
more of the following types of operation on a
regular basis:
● Operating continuously at or near maxi-
mum engine speed (rpm) for many hours
● Operating continuously at a low engine
speed (rpm) for many hours
● Operating without sufficient time for engine
to warm up and cool down
● Frequent quick acceleration and decelera-
tion
● Frequent shifting
● Frequently starting and stopping the en-
gine(s)
● Operation that fluctuates often between
light and heavy cargo loads
Outboard motors operating under any of
these above conditions require more frequent
maintenance. Yamaha recommends that you
do this service twice as often as specified in
the maintenance chart. For example, if a par-
ticular service should be done at 50 hours, do
it instead at 25 hours. This will help prevent
more rapid deterioration of engine compo-
nents.
