Over-rev Limiter
Running the engine without water
can cause serious engine damage
due to overheating. Be sure that
water flows from the cooling water
check hole while the engine is
running. If not, stop the engine and
determine the cause of the problem.
OPERATION
WATER CHECK HOLE
When the overheat warning system
operated (red indicator light turned
on):
If water is flowing, continue idling
(within 30 seconds).
The warning system is normal if it
stops.
If the warning system is still
operating, return to the pier at low
speed and service the system.
Return the shift lever to the N
(neutral) position (idle speed)
immediately, and check whether
water is flowing out of the cooling
water check hole.
BF8D/BF10D/BF15D/BF20D
outboard motor is equipped with the
over-rev limiter which operates when
the engine speed increases
excessively for some reasons while
cruising or when the propeller races
while tilting up the outboard motor or
changing the cruising course.
When the over-rev limiter operated:
Slow down the engine speed
immediately and check the tilt
angle.
If the tilt angle is proper but the
engine speed is too high, stop the
engine and check the outboard
motor and propeller for installation
condition and damage. Correct or
service if necessary.
