TAKING CARE OF UNEXPECTED PROBLEMS
If the engine overheats, the overheat
indicator will come on, and the
engine will stop in 20 seconds after
the engine protection system limits
engine speed. If you are at cruising
speed, engine speed will decrease
automatically.
All types are equipped with a buzzer
that sounds when the overheat
indicator comes on.
Engine overheating may be the result
of restricted water intake screens, or
there may be a problem with the
cooling system thermostat or water
pump.
If the engine is stopped after running
at full throttle, and then restarted soon
afterward, that could activate the
engine protection system
momentarily.
If overheating activates the engine
protection system, idle the engine in
neutral, and check the cooling system
indicator.
If water is flowing from the cooling
system indicator, continue idling for
30 seconds. If the cooling system is
OK, the overheat indicator should go
off within 30 seconds, and the engine
will respond normally to throttle
control lever operation.
If there is no water flowing from the
cooling system indicator, stop the
engine, and tilt the outboard motor to
inspect the water intake screens. If
restricted, clean the water intake
screens, return the outboard motor to
the running position, restart the
engine, and check the cooling system
indicator again.
If there is still no water flowing from
the cooling system indicator, or if the
engine protection system remains
activated after 30 seconds, return to
the nearest boat landing, and have the
outboard motor inspected by an
authorized TOHATSU dealer.
