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”).
