Periodic maintenance

EWM01982
WARNING
These procedures require mechanical
skills, tools, and supplies. If you do not
have the proper skills, tools, or supplies to
perform a maintenance procedure, have a
Yamaha dealer or other qualified mechan-
ic do the work.
The procedures involve disassembling the
motor and exposing dangerous parts. To
reduce the risk of injury from moving, hot,
or electrical parts:
 Turn off the engine and keep engine
shut-off cord (lanyard) with you when
you perform maintenance unless other-
wise specified.
 Allow the engine to cool before handling
hot parts or fluids.
 Always completely reassemble the mo-
tor before operation.
Maintenance, replacement, or repair of
the emission control devices and systems
may be performed by any marine engine
repair establishment or individual. All war-
ranty repairs, however, including those to
the emission control system, must be per-
formed by an authorized Yamaha marine
dealership.
A service manual is available for purchase
through your Yamaha dealer for owners who
have the mechanical skills, tools, and other
equipment necessary to perform mainte-
nance not covered by this owner's manual.

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
58
control could endanger the operator and pas-
sengers. Yamaha genuine parts and acces-
sories are available from your Yamaha dealer.

Maintenance interval guidelines

The service intervals provided in the Mainte-
nance Chart were developed based upon
"typical" use that includes operating at varied
speeds, with sufficient time for engine warm
up and cool-down, a medium to light load,
and an average cruising speed near the 3000
to 4000 rpm range. As with any engine, how-
ever, if your normal operating conditions are
different, you should consider service more
often than shown, especially how often you
change your engine oil and gear oil. Exam-
ples might include extended wide-open-
throttle use or long periods of trolling or
idling, carrying heavy loads, or frequent start-
ing and stopping or shifting. More frequent
maintenance will often pay off many times
over in increased engine life and greater own-
er satisfaction. Consult your Yamaha dealer
for additional maintenance recommenda-
tions.
