ENGINE OPERATION

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.
2. Check for water, fuel or oil leakage from
the engine.
3. Check that the exhaust 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
pipe. 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. NOTICE: The engine will
seize if it is operated when cooling
seawater discharge is inadequate or if
load is applied without any warm-up
operation.
