The electric fuel valve is wired to the ignition
switch. When the ignition is turned ON the valve
opens, when the ignition is turned OFF the valve
closes. The manual override knob on the side of
the valve should be left in the NORMAL position
at all times.
In the event of an electrical malfunction, the valve
can be opened and closed manually by turning
the manual override knob. The electric fuel valve is
installed in-line on the fuel hose between the fuel
tank and the engine. If your boat is equipped with an
optional generator, an additional electric fuel valve
will be installed on the fuel hose between the fuel
tank and the generator fuel filter.

Sea Ray Sport Cruisers are equipped with a fuel
®
tank vent for each tank which serves as a pressure/
vacuum release and safety overflow. The thru-hull
fitting (diesel option) has a flame arrester, making
it imperative that you keep the screen clean and in
excellent repair. Replace the screen immediately if it
becomes damaged or displaced. Periodically check
the vents to assure that they are not clogged.

The quality of the fuel is very important for satisfactory
engine performance and long engine life. Care
should be taken to select fuels having the octane
rating recommended for the engine, as indicated
in the owner's manual, for proper operation. Fuel
should be clean and free of contamination. Your fuel
tanks should be kept full of fuel whenever possible.
This will reduce the amount of water condensation
and reduce the possibility of contamination.

GASOLINE RECOMMENDATIONS
Minimum octane rating of 87 AkI.
The use of improper gasoline or additives can damage
your fuel system and is considered misuse of the
system. Damage caused by improper gasoline or
additives WILL NOT be covered under warranty.
Ethanol is an oxygenated hydrocarbon compound
that has a high octane rating and therefore is
useful in increasing the octane level of unleaded
gasoline.
The fuel-system components of your Mercury
engine(s) have been tested to perform with the
maximum level of ethanol blended gasoline (10%
ethanol) currently allowed by the EPA in the United
States.
Special precautions should be considered with
the use of fuel containing ethanol in your system.
Fuels with ethanol can attack some fuel-system
components, such as tanks and lines, if they are
not made from acceptable ethanol compatible
materials. This can lead to operational problems
or safety issues such as clogged filters, leaks or
engine damage.
Your boat was manufactured, and shipped from the
factory, with ethanol-compatible materials. Before
introducing gasoline with ethanol into your fuel tank,
ask your dealer if any components have been added
or replaced that are not recommended by Sea Ray
Mercury or may not be ethanol-compatible.
