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 qual-
ity. 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 available
from Yamaha dealers.
• The service intervals provided in the maintenance interval charts are based upon "typical" operat-
ing conditions 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 start-
ing and stopping 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.
