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.
