MAINTENANCE WHEN THE ENGINE IS LEFT IDLE
If the boat where the engine is installed
is left idle for a long time, it is necessary
to carry out some maintenance work to
preserve the engine’s maximum efciency
conditions.
If the engine is not used for short periods
of time, carry out the following interven-
tions:
1 -Make sure the electric contacts are
working properly and, if necessary, pro-
tect them with an anti-oxidant spray.
2 -Check the charge of the battery and
the liquid level.
3 -If necessary, carry out the scheduled
maintenance work (see “Engine mainte-
nance”).
It is advisable to start the engine brin-
ging it to the operating temperature
(70÷80°C) at least once per month.
The engine must be started once per
month if it is installed for emergency
purposes.
If the engine is left idle for prolonged
periods, carry out the engine protecti-
ve treatment to guarantee its efciency
for 6 months and to avoid continuous
control and maintenance interventions.
If the engine is not used for a further
period of time, check the need to re-
peat the protective treatment for other
6 months (see “Engine Storage”).
