Wintering
Read carefully the engine operating manual supplied with the boat, particularly the instructions on
wintering.
In the absence of instructions, proceed as follows:
- Close the engine water inlet seacock,
- Disconnect the pipe from the engine water inlet seacock,
- Drain the seawater circuit,
- Place the pipe into a drum of coolant –25° C,
- Turn the engine until you see the coolant coming out of the exhaust,
- When the operation has been completed, reconnect the pipe to the seacock,
- Attach a notice to the electrical panel and the battery switches indicating that the engine water
inlet seacock is closed.
IX. FUEL INSTALLATION
Any damaged fuel hoses must be replaced with hoses bearing the same markings. Do the same
for all fuel pipes.
CAUTION!
● Depending on the boat’s load and trim, it may not be possible to use the full amount of the
nominal fuel capacity. As a precaution, always maintain a 20% safety reserve.
● Avoid flammable products coming into contact with hot engine parts.
● Clean up any fuel spillages in the boat while filling the tanks.
Never:
● Store flammable materials (especially petrol) in unventilated spaces.
● Smoke while filling the fuel tanks.
● Obstruct ventilation ports (vent, engine ventilation grille): make sure they are kept clear at all
times.
● Modify the installation unless this is performed by a technician with the appropriate marine
engineering qualifications.
