ENGINE OPERATION
6
Before driving the boat, let the engine
run at low speed to let it warm and
allow the oil to circulate through the
engine. If the engine is not warmed
up beforehand, the engine life will
shorten greatly.
This outboard engine automatically
controls warm-up operation, namely,
it runs at a speed slightly higher
than idling just after it is started,
and it reverts to the normal running
at a preset speed after warm-up is
complete.
During the war m-up operation,
c o n f i r m t h a t c o o l i n g w a t e r i s
discharged from the check port and
idle port.
■
Engine speed
Proper idle speed after warm-up
operation.
Do not exceed the full-throttle engine
speed.
2. Warming up the engine
Be sure to stop engine immediately
if cooling water check port is not
discharging water, and check if cooling
water intake is blocked. Operating
engine could lead to overheating
potentially leading to engine damage.
Consult an authorized dealer if the
cause cannot be found.
!
CAUTION
If cooling water is not discharged
and engine operation is continued,
the engine will overheat and damage
occur.
