After the Engine has Started

After the engine has started, 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 76° to 90°C (169° to
194°F).
• Normal oil pressure at 3000 min
0.28 to 0.54 MPa (41 to 78 psi).
2. Check for water, fuel or oil leakage
from the engine.
3. Check that the smoke color, engine
vibration and sound are normal.
4. 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.
5. 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.
