3 First commissioning
10 Checking the coolant level
Once the engine has reached operating tem-
perature, check the coolant level in the expan-
sion tank.
• Vary the revolutions between idling and
2000 rev/min.
• Add coolant if necessary.
With a warm engine, the level will be slightly
higher as indicated.
• Check the coolant temperature.
11 Sea trial
• Check the operation of the remote control.
- Carry out a sea trial
At full load (when the vessel is in motion), the
maximum RPM must correspond to the value
specified in the technical data. The engine
can become overloaded if it doesn’t reach this
RPM! In this case, check the propeller for irre-
gularities and the correct choice of speed and
diameter.
