Yamaha RPM Chart
For most modern Yamaha outboard motors, the recommended Wide-Open
Throttle (WOT) RPM range is 5000-6000 rpm. The ideal target is the upper end of
this range, around 5700-6000 rpm, to ensure optimal performance and engine
health.
The specific Yamaha RPM range can vary by engine model and year.
The following table provides typical Wide-Open Throttle (WOT) RPM ranges for
various Yamaha outboard and stern drive models based on information from
sources like Rubex Props and manufacturer data.
Important Considerations:
Propeller Pitch
Reaching the proper WOT RPM is crucial for
engine longevity. If your engine's WOT RPM is too low (lugging the engine), you
need to decrease propeller pitch. If it's too high (hitting the rev limiter),
you need to increase pitch. Changing pitch by one inch typically changes WOT
RPM by about 200 RPM.
Optimal Cruise RPM
For most gasoline outboards, a good fast cruise RPM is around 75% of max output (e.g., 4000-4500 RPM for an engine rated at 6000 RPM). This provides good speed while reducing engine strain and improving fuel economy.
Consult the Manual
These Yamaha propeller charts are for reference; always consult your specific engine's owner's manual for the precise recommended RPM range and maintenance schedule.
