Overheating Indicator Light Comes On And Engine Speed Is Limited - Honda Marine BF15D Owner's Manual

TAKING CARE OF UNEXPECTED PROBLEMS
OVERHEATING INDICATOR
LIGHT COMES ON AND
ENGINE SPEED IS LIMITED
If the engine overheats, the red
indicator light will come on, and the
engine protection system will limit
engine speed. If you are at cruising
speed, engine speed will decrease
automatically.
Remote-control types are equipped
with a buzzer that sounds when the
red indicator light comes on.

Engine overheating may be the result
of clogged 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
(RED) 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.
If water is flowing from the cooling
system indicator, continue idling for
30 seconds. If the cooling system is
OK, the red indicator light should go
off within 30 seconds, and the engine
will respond normally to throttle grip
or 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 clogged, 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 Honda
marine dealer.
