EMU34446

Maintenance chart 1

TIP:

●Refer to the sections in this chapter for explanations of each owner-specific action.

●The maintenance cycle on these charts assume usage of 100 hours per year and regular flushing of the cooling water passages. Maintenance frequency should be adjusted when op- erating 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 in salt water, muddy, other turbid (cloudy), acidic water, the engine should be flushed with clean water after each use.

The “” symbol indicates the check-ups which you may carry out yourself. The “” symbol indicates work to be carried out by your Yamaha dealer.
