ESG (A device preventing over
revolution)
ESG is a device to prevent over revolution
of the engine.
If the load to the engine becomes light for
some reason, it runs at a higher speed
than the usual. In such the case, the
buzzer sounds and the ESG is activated
not to ignite the spark plug, therefore, the
engine speed varies.
Remedy:
Immediately turn the throttle grip or the
control lever to the intermediate or lower
speed and move the boat to a safe place.
Then, shift the control lever or shift lever to
the Neutral (N) position and stop the
engine.
Engine speed to activate ESG: 6000 rpm approx.

propeller.
 If the pitch of the propeller is small and
the engine runs at a high speed (rpm),
replace the propeller with another proper
within the full-throttle speed range.
