Maintenance
Outline
• To obtain long product life,
Selva
strongly recommends that the specified periodic checks and
maintenance be performed according to the maintenance interval chart.
• If replacement parts are necessary, use only genuine
Selva
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.
Selva
genuine parts and accessories are avail-
able from
Selva
dealers.
• The service intervals provided in the Maintenance Chart are based upon “typical” operating condi-
tions 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 to 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. Consult a
Selva
dealer for additional recommendations.
• The maintenance cycle on these charts assumes usage of 100 hours per year and regular flush-
ing 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.
