Outline
• To obtain long product life, Yamaha strongly recommends that the specified periodic checks and
maintenance be performed according to the maintenance interval charts.
• If replacement parts are necessary, use only genuine Yamaha parts of equivalent design and
quality. Any parts of inferior quality may cause a malfunction, and the resulting loss of control
could endanger the operator and passengers. Yamaha genuine parts and accessories are avail-
able from Yamaha dealers.
• The service intervals provided in the maintenance charts are based upon "typical" operating con-
ditions that include speed variations, sufficient time for engine warm up and cool-down, medium to
light load, and an average cruising speed in the 3000–4000 r/min range. If your normal operating
conditions are more intensive, more frequent servicing will be required, especially the engine oil
and gear oil changes. Examples of the intensive operation will be: wide-open-throttle, trolling, or
idling operation for extended periods of time, carrying heavy loads, and frequent starting and stop-
ping or shifting. In most cases, the frequent maintenance pays off in increased engine life and
greater owner satisfaction.
• The maintenance cycle on these charts is based on usage of 100 hours per year and regular
flushing of the cooling water passages. Adjust the maintenance frequency when operating the
engine under adverse conditions, such as extended trolling.
• Disassembly or repairs may be necessary depending on the outcome of maintenance checks.
• Expendable or consumable parts and lubricants will lose their effectiveness over time and through
normal usage regardless of the warranty period.
• When operating the outboard motor in salt water, or in muddy, turbid (cloudy), or acidic water,
flush the engine using clean water after each use.
