2. MT-3: Pull out the handle lever
(Figure 3, (4)) and adjust the speed to
no more than 1500 rpm and run the
engine at low speed with no load.
3. MV: Pull out the free throttle button
(Figure 4, (4)) and adjust the speed to
no more than 1500 rpm and run the
engine at low speed with no load.
4. Allow engine to run for approximately 5
minutes.
Check the following items at a low engine
speed:
1- Check that the gauges, indicators
and alarm are normal.
• Normal coolant operating temperature
is approximately 70° to 90°C (158° to
194°F).
• Normal oil pressure at 3000 min
-1
is
0.34 to 0.54 MPa (48 to 78 psi).
1- Check for water, fuel or oil leakage
from the engine.
2- Check that the smoke color, engine
vibration and sound are normal.
3- When there are no problems, keep
the engine at low speed with the boat
still stopped to distribute engine oil to
all parts of the engine.
4- Check that sufficient cooling water is
discharged from the seawater outlet.
Operation with inadequate seawater
discharge will damage the impeller
of the seawater pump. If seawater
discharge is too low, stop the engine
immediately. Identify the cause and
repair.
The engine will seize if it is operated when
seawater discharge is too small or if load is
applied without any warming up operation.
