Generator
Over time, water can condense inside the fuel tanks, especially in areas with high
humidity. This water can then react with the fuel in the tanks to create a mixture that
can corrode the tanks from the inside. To avoid this:
• Use the fuel in the fuel tanks as often and as completely as possible.
• Keep the tanks full of fuel when the boat is stored and when it is used infrequently.
• Do not put alcohol-based fuels in the tanks without checking with the engine
manufacturer.
Fuel Shut-Off Valves
Fuel supply shut-off valves are located on the top of the fuel tanks near the
aft inboard corner. These valves must be open when operating the engines.
Fuel Tank Vents
Each fuel tank is vented overboard. As the fuel tanks are filled during
fueling, air is displaced from inside the tanks and escapes through the vents.
Conversely, when the engines are running, air enters the fuel tanks through
the vents to displace the fuel being used.
