VIII. ENGINE
Regular maintenance must be carried out in compliance with the engine manufacturer’s
recommendations. Read the engine operating instructions that come with the boat carefully. Do not
hesitate to consult your agent or a qualified professional. In particular, follow the instructions for
wintering.
General precautions
Do not use the sail and engine if the heel angle is more than 10°.
Any engine change must respect the
capacities of the boat and be performed by an engineer
specializing in marine mechanics.
After the first launching and tensioning of rigging, check the alignment of the propeller shaft or the
sail-drive flange ring.
● Ensure that the ventilation openings (vents, engine air intake grating) are clear.
●
Make sure that the water intake seacock for the cooling system is open, and that water is
indeed coming out of the engine exhaust.
● Prevent any deterioration to the fuel supply circuits.
● Do not store equip
ment containing petrol (outboard motor, tank, petrol generator, etc.) in
compartments not designed for this purpose.
Put the throttle in neutral before starting the engine to keep the boat from moving and/or the
propeller from turning.
On subsequent launches, a brief check of propeller fixing can be made. Incorrect operation of the
folding propeller will lead to vibration.
Regularly check the condition of the anodes and ensure that they are suitable for the boat's
environment (fresh water, salt water). Change the anodes every year. The anodes have an
average life of 1–2 years.
These anodes are made of zinc. You must not use magnesium ones. Impressed current cathodic
protection systems should be avoided.
If the anodes are not eroded, you need to check:
- that they have not been painted over,
- that they are correctly attached and in contact with the hull,
- and that they are indeed made of zinc.
Exhaust gas emission
DANGER!
Internal combustion engines produce carbon monoxide. Prolonged exposure to
can have serious consequences, and may even cause death.
Safety
DANGER!
In order to avoid all risk of serious injury from the propeller, the engine must not be started when
there are people swimming near the boat.
Whenever possible, the
engine must be stopped for any engine maintenance or checking
operations. Otherwise, special attention must be paid to moving parts (propeller shafts, belts,
etc.) in order to avoid any risk of injury.
