Starting Procedure - Westerbeke 12C-TWO Operators Manual And Installation Manual

STARTING PROCEDURE
Place the transmission in the NEUTRAL position and advance the throttle to its full open position for a
cold engine and partially open for a warm engine.
Turn the Key Switch to the ON position
(2
o'clock).
Depress and hold the PREHEAT switch. Preheat according to the following chart:
Atmospheric Temperature Preheating Time
+ 41° F (+ 5° C) or higher
+ 41° F (+ 5° C) to + 23° F (_5° C)
+23° F (_5° C) or lower
Approx. 05 sec.
Approx. 10 sec.
Approx. 15 sec.
Limit of continuous use
30 seconds before cranking
Proper glow plug function is indicated by a voltmeter drop (voltmeter is on the Admiral Panel only) when
the PREHEAT switch is depressed. This drop will be slight but discernible. If no voltage drop is noted, it
may indicate defective glow plugs or a faulty preheat circuit(check for loose connections).
While holding the PREHEAT button depressed, depress
the START button. The starter motor will run, thereby
cranking the engine. As soon as the engine runs, release
the START button and PREHEAT button. Check your
instrumentation for proper engine operation. Make sure
sea water discharges along with the exhaust discharge.
Should the engine not start when the START switch is
depressed for 10 to 12 seconds, release both switches
and wait 30 seconds; repeat the procedure above. Never
run the starter for more than 30 seconds at a time.

Prolonged cranking intervals without the engine starting can result in filling the engine mounted
exhaust system with sea water coolant. This may happen because the sea water pump is pumping
sea water through the sea water cooling system during cranking. This sea water can enter the
engine's cylinders by way of tbe exhaust manifold once tbe exhaust system fills. Prevent this from
happening by closing the sea water supply througb-bull, drain the exhaust muffler, and correct the
cause of tbe excessive engine cranking needed to obtain a start. Engine damage resulting from this
type of sea water entry is NOT a warrantable issue, the owner/operator should keep this in mind.
Once the engine starts, run it at idle for a few minutes to warm up tbe engine and check instruments for
proper oil pressure and battery cbarging voltage. Never attempt to engage the starter while the engine is
running.
NOTE: Some unstable running may occur in a cold engine, but this condition should smooth out as the
operating temperature of 170 - 190° F is reached.
