Restarting After Starting Failure; Starting At Low Temperatures - Yanmar 2YM15 Operation Manual

5. Turn key switch to ON (Figure 1, (3)).
Ensure that the instrument panel
indicators light and the alarm sounds.
This indicates that indicators and alarm
are working correctly.
Note: The coolant high
temperature alarm indicator and
water in Sail-Drive indicator should
not come on during start-up.
6. Turn key switch to START
(Figure 1, (4)). Release the key switch
when the engine has started. NOTICE:
NEVER hold the key in the START
position for longer than 15 seconds
or the starter motor will overheat.
7. The alarm should stop and the
indicators should go out. NOTICE: If
any indicator fails to illuminate
when the key switch is in the ON
position, see your authorized
Yanmar Marine dealer or distributor
for service before operating the
engine.
Note: When the engine has not been used
for a long period of time, check that the key
moves smoothly from the START position to
the ON position.

Restarting After Starting Failure

Before turning the key switch again, be sure
the engine has stopped completely. NEVER
attempt to restart the engine while the
engine is running. The pinion gear on the
starter motor will be damaged. NOTICE:
NEVER hold the key in the START
position for longer than 15 seconds or
the starter motor will overheat.
NOTICE: NEVER attempt to restart the
engine if the engine has not stopped
completely. Pinion gear and starter
motor damage will occur.
YM Series Operation Manual
Air Bleeding the Fuel System After
Starting Failure
If the engine does not start after several
attempts, there may be air in the fuel system.
If air is in the fuel system, fuel cannot reach
the fuel injection pump. Bleed the air out of
the system. See Bleeding the Fuel System
on page 25.

Starting at Low Temperatures

Comply with local environmental
requirements. Use engine heaters to avoid
starting problems and white smoke.
NOTICE: NEVER use an engine starting
aid such as ether. Engine damage will
result. Using a starting aid may void the
warranty.
To limit white smoke, run the engine at low
speed and under moderate load until the
engine reaches normal operating
temperature. A light load on a cold engine
provides better combustion and faster
engine warm-up than no-load.
Avoid running the engine at idling speed any
longer than necessary.
