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, howev-
er, if your normal operating conditions are dif-
ferent, you should consider service more

often than shown, especially how often you
change your engine and gear oil. Examples
might include extended wide-open-throttle
use or long periods of trolling or idling, carry-
ing heavy loads, or frequent starting and stop-
ping or shifting. More frequent maintenance
will often pay off many times over in increased
engine life and greater owner satisfaction.
Consult your Yamaha dealer for additional
maintenance recommendations.
