ENGINE

The boat is fitted with 2 tanks (1 in each hull).
They are both filled independently.
They both have a fuel gauge on the engine panel.
• FILLING
Take the general precautions stated in chapter 7 about the water
tank filling.
Fill the tanks using the 2 fuel fillers.
In order to protect the deck from possible fuel splash, wet the area
around the filler with sea water before you remove the filler cap.
In case of splashes, rinse the deck thoroughly (after fitting back the
filler cap).
• MAINTENANCE
- Regularly check the O ring of the filler for good condition (in order
to prevent water entries).
- Do not turn off the fuel tap after each use (except in case the boat
is unattended for long).
- Keep the fuel tank as full as possible (to avoid condensation).
- Every 5 years clean the tank to remove possible sludge deposi-
tion.
- Every year check the fuel system for condition (hose, valves, etc.).
NOTE: The capacity of the fuel tank or tanks indicated in the page
"Specifications" cannot be completely used according to the trim
and load of the boat.
Always keep 20 % fuel as a reserve.

DANGER
