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.
