ENGINE RELUCTANT TO START
If a water lift (water lock) muffler is installed on the
exhaust line, excessive cranking could cause seawater
to enter the cylinders and damage the engine. To start
engine, reduce starting attempts to three and if not OK,
undertake to do this :
1.
Close the seacock to avoid filling the muffler with
water.
2. Try to start the engine by following the regular
starting procedure.
3. When the engine does start, stop the engine
immediately and turn off the switch.
4. Re-open the seacock and restart the engine.
IDLING ENGINE
Avoid excessive engine idling as it may cause the coolant
temperature to fall below its normal range. This, in turn,
causes crankcase oil dilution, due to incomplete fuel
combustion, and permits formation of gummy deposits
on valves, pistons, and piston rings. It also promotes
rapid accumulation of engine sludge and unburned fuel
in the exhaust system.
Once an engine is warmed to normal operating
temperatures, engine should be idled at slow idle speed.
Slow idle speed for engine is set at the factory. If an
engine is left idling for more than 5 minutes, stop and
restart later.
Above : temperature and pressure on classic gauges.
NORMAL ENGINE OPERATION
Check engine coolant temperature and oil pressure.
Temperatures and pressures will vary between engines
and with changing operating conditions, temperatures,
and lIf coolant temperature rises above the maximum
coolant temperature, reduce load on engine. Unless
temperature drops quickly, stop engine and determine
cause before resuming operation.
Operate the engine under a lighter load and at slower
than normal speed for first 15 minutes after start-up.
DO NOT run engine at slow idle unless necessary for
maneuvering out of dock and harbor.
Stop engine as soon as possible if there are any signs of
part failure. Symptoms that may be early signs of engine
problems are :
• Sudden drop in oil pressure
• Abnormal coolant temperatures
• High marine gear oil temperature
• Unusual noise or vibration
• Sudden loss of power
• Excessive black exhaust
• Excessive fuel consumption
• Excessive oil consumption
• Fluid leaks
