Maintenance

77

 The power trim and tilt switches oper-

ate even when the ignition key is off.

Keep people away from the switches

whenever working around the motor.

When the motor is tilted, keep away

from the area under it or between it and

the clamp bracket. Be sure no one is in

this area before operating the power

trim and tilt mechanism.

 Allow the engine to cool before han-

dling hot parts or fluids.

 Always completely reassemble the mo-

tor before operation.

Maintenance, replacement, or repair of

the emission control devices and sys-

tems may be performed by any marine

engine repair establishment or individual.

All warranty repairs, however, including

those to the emission control system,

must be performed 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

control could endanger the operator and

passengers. Yamaha genuine parts and ac-

cessories 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,

however, 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. Ex-

amples might include extended wide-open-

throttle use or long periods of trolling or

idling, carrying heavy loads, or frequent

starting and stopping or shifting. More fre-

quent maintenance will often pay off many

times over in increased engine life and great-

er owner satisfaction. Consult your Yamaha

dealer for additional maintenance recom-

mendations.
