Warning System - TOHATSU 40B2 Owner's Manual

6. Warning system

When there is something abnormal
with the engine, the warning lamp
flashes and/or the buzzer sounds.
If a trouble occurs, deal with it as
mentioned below.
■ 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:6,000rpm approx.
Note
● If the propeller is damaged such
as worn, broken, bent propeller
blade(s) or slipping propeller,
rubber, replace the 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.
