Fuel System
by attempts to force additional fuel into the tank.
After fueling, close and latch the fill cap. Then
wash spilled fuel from the areas around the fuel
fill if necessary. Residual fuel left on the deck and
hull sides can be dangerous and will yellow the
fiberglass or damage the striping.
5.2 Outboard Engine Fuel System
The gasoline fuel system has one fuel tank that
fills from the port or starboard gunnel. Each
engine is supplied by an independent withdrawal
tube and fuel line. Quad engine fuel tanks have
four withdrawal tubes and fuel lines. There is an
on/off valve for each supply line located on the
fuel tank near each withdrawal tube. The valves
provide a means to turn off the fuel supply to
service the fuel system.
Fuel withdrawal lines are equipped with anti-
siphon valves where the lines attach to the fuel
tanks. These valves prevent gasoline from siphon-
ing out of the fuel tank should a line rupture.

WARNING
DO NOT REMOVE THE ANTI-SIPHON VALVES FROM THE
SYSTEM. SHOULD AN ANTI-SIPHON VALVE BECOME
CLOGGED, CLEAN AND REINSTALL OR REPLACE. IF A
FUEL LINE SHOULD LEAK, ANTI-SIPHON VALVES PREVENT
A SUBSTANTIAL AMOUNT OF FUEL FROM FLOWING INTO
THE BILGE. ANTI-SIPHON VALVES ARE REQUIRED TO BE
INSTALLED IN ALL BOATS EQUIPPED WITH GASOLINE

Engine Fuel Filters
On most engine installations, the fuel filter for
each engine is installed in the aft systems com-
partment. The filters are accessed through the
hatch at the rear of the cockpit sole. The filters
are the water separator type and should be ser-
viced frequently to assure an adequate supply of
clean, dry fuel to the engines. It is recommended
that the filters be inspected periodically and the
elements changed as needed.
