Fuel System
The shuto valves will not allow additional fuel to
be added after they close and could be damaged
by attempts to force additional fuel into the tank.
After fueling, close and latch the ll cap. Then
wash spilled fuel from the areas around the fuel
ll if necessary. Residual fuel left on the deck and
hull sides can be dangerous and will yellow the
berglass gelcoat or damage the striping.
5.2 Outboard Fuel System
The fuel system has one fuel tank located in the
center of the bilge below the cockpit sole. The Fuel
withdrawal line is equipped with an anti-siphon
valve where the line attaches to the fuel tank.
This valve prevents gasoline from siphoning out
of the fuel tank should a line rupture.
DO NOT REMOVE THE ANTI-SIPHON VALVES FROM THE
SYSTEM. SHOULD THE VALVE BECOME CLOGGED, CLEAN
AND REINSTALL OR REPLACE.
Typical Yamaha Fuel Filter & Primer Bulb
The engine fuel lter is installed in the aft sys-
tems compartment bilge. The lter is accessed by
raising the aft bench seat. The lter is the water
separator type and should be serviced frequently
to assure an adequate supply of clean, dry fuel
to the engine.
It is recommended that the lter be inspected
periodically and the element changed as needed.
A valve located near the fuel withdrawal tube
provides a means to turn o the fuel supply
while servicing the fuel lter or any fuel system
component.
There is a primer bulb in the fuel line located near
the fuel lter 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 on the fuel lter and the
outboard engine fuel system.
Notice:
The procedure to prime the fuel system on
outboard engines is specic to the type and
model of engine on your boat. You should re-
fer to engine manufacturer owner’s manual
for the priming procedure for your engine.
