Operation of the engine
During operation
RPM speed of the engine
Refer to the chapter «Technical specifications» for informa-
tions about the rated rpm speed of your engine.
Do not operate the engine at a too low rpm speed for a
long period as it could lead to increased oil consumption
among other things. At a low speed, the fuel combustion is
not complete and deposits may form in the engine and in
its exhaust system. Run the engine at full throttle for 4 to 5
hours per year in order to burn off any possible deposits.
Cruising spee d
Set your cruising speed to 200 rpm below the maximum
speed at full throttle for the best sailing conditions.
Forward / reverse speed
I
Danger! :
Never reverse the gear when the boat is at full
speed. Gear changes made at too high speed can damage
the engine and the transmission.
Carry out the following operations for forward / reverse
manoeuvres:
1.
Lower the engine down to idling and wait for the boat
to lose as much speed as possible.
2.
Bring the throttle to the neutral position and wait a few
seconds.
3.
Push the control lever to the reverse direction and
change gear.
Running in
Operate your engine with care for the
fi
rst 50 hours of op-
eration.
Do not accelerate immediately after starting the engine
without giving the engine the time to warm up by idling for
several minutes and only run at full speed for short periods
of time.
Stopping the engine
Let the engine run at idle in the neutral position for few min-
utes before turning it off, particularly if the engine has been
running at high speeds and high throttle settings.
Turn the key counter-clockwise. The engine stops and all
the indicators will be extinguished.
For button panels, depress the ON/STOP button and then
release it.
Emergency stop
You can stop the engine manually if the standard shut-
down procedure is not working or in an emergency by cut-
ting the fuel supply.
I
Danger! :
Working on a running motor is extremely
dangerous.
After the engine has stopped
Open the circuit breaker (battery supply off), close the sea-
water intake valve (if
fi
tted) and the fuel feed valve. Check
the condition of the compartment in order to identify any
leaks.
I
Danger! :
Even after your engine has stopped, ele-
ments remain hot and pressurised for several minutes. As
far as possible, limit work on the engine immediately after
stopping it.
I
Attention! :
If the craft is being towed, stop the engine
and always close the seawater intake valve to prevent the
engine from accidentally
fi
lling with seawater.
TWIN-ENGINE BOATS:
If sailing with a single engine,
close the seawater intake valve of the stopped engine. Do
not forget to open it again before restarting the engine.
