C. PROPULSION SYSTEM
This chapter describes the propulsion system
of your Grand Soleil 39, and in particular the
engine and the marine gear.
The propulsion system is installed in “saildrive”
configuration.
We advise you to acquire at least a basic
working knowledge of the basic operating
features of the propulsion system before
sailing, and to seek the help and advice of an
expert if necessary.
In particular, you should become familiar
with the use of this type of propulsion system
for manoeuvring the boat. When movement
ahead or astern is selected, in addition to
generating a longitudinal thrust (from the
stern to the bows or vice versa), the propeller
also tends to move the stern sideways, in
one direction when moving astern and in
the other when moving astern, and also
facilitating or contrasting the effect of the
rudder. This feature, if understood and
applied practically, facilitates manoeuvres for
mooring or in tight spaces, and can counteract
a wind blowing from abeam when the boat is
at a standstill or moving only very slowly.
C.1 ENGINE
The standard engine installed on your boat is
a VOLVO D1-30 3-cylinder model rated at 20.9
kW (28.4 MHP = Metric Horse Power) at 3,200
RPM. Cruising speed must be kept beneath
2,600 RPM, and in these conditions the hourly
fuel consumption will remain below 4 litres /
hour, which may however vary according to
displacement, the condition of the hull and
the cleanliness of the engine filters.
As an alternative, a VOLVO D2-40 4-cylinder
engine can be installed, rated at 29.1 kW
(39.6 MHP) at 3,200 RPM. The hourly fuel
consumption of this engine beneath 2,600
RPM (cruising speed) is below 5 litres/hour.
The engine has a 115 A alternator to charge
the batteries. The engine monitoring panel is
located to the starboard side of the starboard
helm station in the cockpit.
Instruction manuals compiled by the engine
manufacturer are provided separately. We
advise you to read them carefully and to
follow the indications given.
The engine is covered by the manufacturer’s
guarantee. Only technicians authorized by the
manufacturer should be allowed to work on
them. Failure to comply with this requirement
will lead to the invalidation of the guarantee.
We strongly advise you to learn to recognize
the main engine components by consulting
the explanatory diagrams in the instruction
manual (various types of filter, fuel injectors,
manual pump for priming fuel injection
circuit, drive belt, manual stopping, throttle
control) and to become familiar with some of
the most frequent operations (checks on oil
and freshwater levels, manual stopping, oil
and filter changes, correct tension of drive
belt, etc).
The engine is cooled by a sealed freshwater
circuit, which is in turn cooled by seawater.
The seawater system has a filter that can be
opened for cleaning.
The cooling seawater is discharged together
with the exhaust gases. When sailing under
engine power, constant checks should be
made on the correct flow of cooling seawater
from the discharge outlet at the stern.
The freshwater level in the sealed cooling
circuit (tank in the engine compartment) must
be checked before starting the engine.
THE ENGINE COOLING FRESHWATER
IN THE TANK CAN REACH VERY HIGH
TEMPERATURES AND CAN CAUSE
SCALDING. OPEN THE CAP WITH
GREAT CARE.
For winter use, the sealed cooling circuit
must contain an antifreeze product like that
normally used in motor vehicles. When your
boat is delivered, the cooling circuit already
contains an antifreeze additive.
