Starting/Stopping Procedure - Westerbeke 44A FOUR-35 C THREE Operator's Manual

STARTING/STOPPING PROCEDURE
THE STARTING SYSTEM
The 44N35Cdiesel engine has a 12V DC electric starter.
The start circuitry is designed so that the PREHEAT button
must be depressed for the time specified in the preheat chart.
Then, while keeping the PREHEAT button engaged, the
START button is depressed to crank the engine.
Starting Procedure
1.
Place the transmission in neutral and advance the throttle
control to slightly open.
A
CAUTION:
Make certain the transmission is
in neutral. Starting in gear could result in serious
damage to your transmission, your boat, and
vessels nearby.
2. Tum the KEY SWITCH to the ON position (2 o'clock).
3. Depress the PREHEAT switch. The voltrrieter, panel
lights, gauges, meters and fuel solenoid will be activated.
The PREHEAT switch should be depressed in accor-
dance with the following chart:
TemperatureJPreheat
Atmospheric Temperature Preheating Time
41°F(5°C) or higher Approx. 10 seconds
41°F(5°C) to 23°F (-5°C) Approx. 15 seconds
23°F(-5°C) or lower Approx. 20 seconds
Limit of continuous use 30 seconds before cranking
NOTE:
The START button will not energize unless the PRE-
HEAT button is depressed. Depressing the PREHEAT button
activates the glow plugs in the cylinder head so use the PRE-
HEAT intermittently to avoid overheating the glow plugs.
4. While still depressing the PREHEAT button, depress the
START button. This will engage the starter solenoid.
Upon engine starting, release the START switch. Do not
release the PREHEAT switch until the oil pressure reaches
5 - 10 psi. Then as long as the high water temperature and
low oil pressure protective circuits do not activate, the engine
will remain energized and continue to run.
NOTE:
When starting:
A voltage drop will occur
when the preheat button
is depressed.
5. Should the engine not start when the START button is
depressed for 10 to 20 seconds, release both buttons and
wait 30 seconds; repeat the procedure above and preheat
longer. Never run the starter for more than 30 seconds.
A
CAUTION:
Prolonged cranking intervals without
the engine starting can result in the engine exhaust
system filling with raw water. This may happen because
the pump is pumping raw water through the raw water
cooling system during cranking. This raw water can
enter the engine's cylinders by way of the exhaust
manifold once the exhaust system fills. Prevent this
from happening by closing the raw water supply
through-hull shutoff, draining the exhaust muffler, and
correcting the cause of the excessive engine cranking.
Engine damage resulting from raw water entry is not a
warrantable issue; the owner/operator should keep this
in mind.
6. Once the engine starts, check the instruments for proper
oil pressure and battery charging voltage.
NOTE:
Never attempt to engage the starter while the
engine is running.
NOTE:
Some unstable running may occur in a cold
engine. Depressing the PREHEAT button for 10- 15
second intervals will help stabilize the engine rpm until
the engine operating temperature reaches 170 -190°F
(77 - 88°C) and a propeller load is applied to the engine.
When the engine is running and the PREHEAT button is
depressed, a charging load on the DC alternator will be
discernible.
Starting Under Cold Conditions
Make sure the lubricating oil is appropriate for the prevailing
temperature. Use oil with an API Specification of CF or CG-4,
SAE 30, lOW-30, or 15W-40.
The battery should be fully charged to minimize voltage drop.
Use a sufficient amount of preheat to aid in starting. See the
Temperature/Preheat chart elsewhere in this section.
Stopping Procedure
To stop the engine, bring the throttle to an idle position and
place the transmission in neutral. Allow the engine to idle for
a few moments to stabilize temperatures. Turn the engine off
using the stop control cable. If your engine is equipped with
an optional fuel shut off solenoid, turn off the key switch at
the control panel.
NOTE:
Make certain this key switch is in the OFF position
( 12 o'clock).
If
the key switch is left ON, the battery will
discharge. An engine alarm buzzer is provided to warn the
operator of this condition (key switch ON). The best method
of preventing the battery from discharging is to remove the
key from the key switch after stopping the engine.
