Fuel System
5.2 Outboard Engine Fuel System
The gasoline fuel system has one fuel tank that
fills from the port gunnel. The starboard engine
is supplied by the starboard fuel line and the port
engine is supplied by the port fuel line. If your
boat is equipped with triple engines, the center
engine will be supplied by a center fuel line. 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 ENGINES BY THE U.S. COAST GUARD
Engine Fuel Filters
On most engine installations, the fuel filter for
each engine is installed in the stern systems
compartment. The filters are accessed through
the hatch at the rear of the cockpit sole. Fuel
filters for Verado engines are mounted on each
engine. The filters are the water separator type
and should be serviced frequently to assure an
adequate supply of clean, dry fuel to the engines.
It is recommended that the filters are inspected
periodically and the elements changed as needed.
There is a primer bulb in each fuel line located in
the systems compartment that is used to prime
the fuel system after service or as required. See
Fuel System Maintenance and the engine owner’s
manual for additional information regarding fuel
filters and the outboard engine fuel system.
Notice:
Clean fuel is especially important in fuel in-
jected engines. The engine manufacturer’s
recommendations for fuel filter maintenance
must be followed exactly.
Yamaha Engine Primer Bulbs in Systems Compartment
Notice:
The procedure to prime the fuel system on
outboard engines is specific to the type and
model of engines on your boat. Not all engine
fuel systems are equipped with primer bulbs.
You should refer to engine manufacturer
owner’s manual for the priming procedure
for your engines.
