Wintering
Read the operating and maintenance instructions for the engine that goes with your boat and the
instructions for wintering carefully.
In the absence of other instructions, proceed as follows:
- Close the engine water intake seacock,
- Disconnect the hose from the engine water intake seacock,
- Drain the sea-water circuit,
- Place the pipe into a drum of –25° anti-freeze coolant,
- Run the engine until the fluid comes out of the exhaust,
- At the end of this operation, re-connect the pipe to the seacock,
- Attach a notice to the electrical panel and the battery isolator stating that the engine water intake
seacock is closed.
IX. FUEL INSTALLATION
In the event of deterioration, flexible fuel pipes must be replaced by pipes bearing the same
markings. Do the same for all fuel lines.
CAUTION!
● Depending on
the trim and loading of your boat, not all of the nominal fuel capacity may be
used. Always maintain a 20% reserve for safety.
● Avoid contact between flammable materials and hot parts of the engine.
● Clean up any overflow of fuel that may occur when filling the tanks.
You must never:
● Store flammable materials in unventilated spaces.
● Smoke while filling tanks.
● Obstruct ventilation openings (vents, engine air intake grating): make sure they are clear.
● Modify the installation except by a qualified technician.
X. HELM SYSTEM
The steering system plays a vital role in the safety and comfort of your boat.
Helm
The DUFOUR 430 is fitted with a dual wheel with a system of rudder cables and chains as well as
with an emergency tiller.
Checks to be carried out periodically: check the play in the various elements (rudder
stock/bearings, tension and wear in mechanical components) and grease the sprocket and chain if
necessary.
Your system is designed with 6mm stainless steel cable, twisted 7x19. These cables may be
replaced due to wear and fatigue.
The frequency of the change depends on the type of use and the tension and maintenance
conditions that might affect their lifespan.
