Frequently check the colour of exhaust fumes:
- clear or light grey: correct combustion;
- dark grey or black: incomplete combus-
tion (dirty air filters, turbo malfunction,
inefficient injectors, valve or head gasket
problems);
- light blue: oil in exhaust fumes (excessive
level, piston ring or valve guide malfunc-
tions);
- whitish: incorrect combustion (low engine
temperature, water in fuel, head gasket
leak, malfunction with injectors, malfunc-
tion with water jacket or supercharger air
radiator).
C.2 TRANSMISSION
Specific instruction manuals compiled by the
manufacturers are supplied separately.
The saildrive propulsion system is an extremely
robust and relatively simple mechanism,
requiring only a minimum of attention to
ensure that it gives an extended period of
service. In particular, its reliability depends
on a few regular checks and the avoidance of
sudden strains while it is being used.
CHANGES OF DIRECTION FROM AHEAD
TO ASTERN AND VICE VERSA SHOULD
ALWAYS BE MADE SLOWLY AND WITH
THE ENGINE AT MINIMUM SPEED. THIS
WILL AVOID CAUSING DAMAGE TO
ENGINE AND MARINE GEAR.
The saildrive has a dipstick for oil level. Periodic
checks (every 200 hours or at least once every
season) must be made on the tightness of
nuts and bolts on the various transmission
components of the propulsion system.
Particular attention must be given to regular
and periodic checks on the surrounding seal
of the of the saildrive transmission. Follow the
instructions provided by the manufacturer,
and carry out all recommended maintenance
and component replacement operations at
the intervals indicated.
THE ZINC ANODES MUST NOT BE
PAINTED OVER, AS THIS PREVENTS
THEM FROM FUNCTIONING CORRECT-
LY. THE ANODES MUST BE REPLACED
WHEN HALF THEIR ORIGINAL WEIGHT
HAS BEEN LOST.
In case of impacts with a submerged object
and damage to the saildrive or propeller, make
immediately for a harbour with the engine
at minimum speed, to prevent vibration
from causing more serious damage to the
propulsion system or other parts of the boat.
With the passage of time, the flexible engine
supports will inevitably settle and lose some
of their elasticity and capacity to absorb
vibrations.
The hull will also settle, and can be subject to
slight deformations, above all when the boat
is laid up for the winter and is not correctly
supported.
All these factors can lead to an increase in
vibrations from season to season.

CAUTION
C.3 PROPELLER
The propeller can be eroded by cavitation or
galvanic corrosion, or damaged by contact
with submerged objects, and should therefore
be inspected regularly.
The propeller can be changed by an expert
technician even with the boat in the water.
All submerged metallic components of the
boat can be subject to galvanic corrosion.
The rapidity of galvanic corrosion is difficult
to predict, as it depends on the overall mass
of metal in the surrounding water, including
chains, jetties and other boats with steel or
aluminium hulls.
The boat is fitted with a Pro Save-C protection
system that operates when the shore power
supply (230 V AC) is connected and powered,
avoiding the excessive erosion of the protective
zinc fittings of the boat.
Check the remaining weight of the protective
zinc fittings regularly, and replace them when
they reach half of their original weight.
