ENGINE OPERATION
8LV Series Operation Manual
29
If the Engine Fails to Start
Before pressing the Start switch again, confirm that
the engine has stopped completely. If the starter
motor is operated before the engine has completely
stopped, the starter motor pinion gear will be
damaged.
The starter will run continuously for 15 seconds and
then stop.
If the engine does not start the first time, wait for
about 15 seconds before trying again.
If the vessel is equipped with a water lift (water
lock) muffler, excessive cranking could cause
seawater to enter the cylinders and damage the
engine. If the engine does not start after cranking
15 seconds, close the thru-hull water intake valve to
avoid filling the muffler with water. Crank for 15
seconds or until the engine starts. When the engine
does start, stop the engine immediately and press
the stop switch. Be sure to re-open the seacock
and restart the engine. Operate the engine
normally.
After the Engine has Started
After the engine has started, check the following
items at a low engine speed:
1. Check that the indicators on the display and the
control head are normal.
2. Check for water or oil leakage from the engine.
3. Check that exhaust color, engine vibrations,
and sound are normal.
4. When there are no problems, keep the engine
at low speed to send engine oil to all parts of
the engine.
5. Check that sufficient seawater is discharged
from the seawater outlet pipe. Operation with
inadequate seawater discharge will damage the
impeller of the seawater pump. If seawater
discharge is too small, stop the engine
immediately. Identify the cause and repair.
• Is the seacock open?
• Is the inlet of the seacock on the hull bottom
clogged?
• Is the seawater suction hose broken, or does
the hose suck in air due to a loose joint?
The engine will seize if it is operated when
seawater discharge is too small or if load is
applied without any warming up operation.
