Overheat And Engine Speed Is Limited - Honda Marine BF9.9D Owner's Manual

OVERHEAT AND ENGINE
SPEED IS LIMITED
(RED)
(R type)
If the engine overheats, the red
indicator light will come on and the
buzzer will sound a continuous tone
as the engine speed is reduced to
1,800 rpm. If the condition persists
for another 20 seconds, the engine
will shut off.
TAKING CARE OF UNEXPECTED PROBLEMS
(H type)
If the engine overheats, the engine
speed will be reduced to 1,800 rpm.
If the condition persists for another
20 seconds, the engine will shut off.
(all types)
If you are at cruising speed when the
overheat protection system is
activated, the engine speed will
decrease automatically. When normal
engine temperature is restored, the
engine speed will gradually rise to
normal engine speed.
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.
COOLING SYSTEM INDICATOR
If overheating activates the engine
protection system, idle the engine in
neutral, and check the cooling system
indicator.
