Fuel Systems
3-2
43 LS
The outboard engines draw fuel from a single
fuel tank. Both fuel fills, on the port and star
-
board gunwale, may be used to fill the tank.
All boats equipped with gasoline engines are
required by the U.S. Coast Guard to have
anti-siphon valves. The fuel delivery lines are
equipped with anti-siphon valves where the
lines attach to the fuel tank. These valves
help prevent gasoline from siphoning out of
the fuel tank should a line rupture.
DO NOT remove the anti-siphon valves from
the system. Anti-siphon valves prevent fuel
from flowing into the bilge should a fuel hose
or fitting leak. If the valve becomes clogged,
clean and reinstall or replace it.
Fuel Tank
The fuel tank holds approximately 400 gal-
lons (1,514 liters) of fuel. Fuel pick-up tubes
are positioned in the tank to achieve optimum
fuel usage, fuel line routing, etc. At certain
speeds and hull trim angles, the fuel sup-
ply at the withdrawal tube can increase or
decrease accordingly. Be extremely careful
when attempting to operate the boat when
low on fuel. Though some fuel may be in the
tank, the trim angle of the boat may cause the
fuel to flow away from the pickup tubes.
Fuel Gauge Senders
The fuel gauge senders are more accu-
rate when the boat is stationary and level.
Because of the change in attitude when the
boat is underway, variations in gauge read-
ings can occur. This system is a relative indi-
cation of the available fuel supply and not a
calibrated instrument.
Fuel Fills
Gasoline fuel fills are located on each gun
-
wale and are marked with a gasoline pump
icon. Both the starboard and port fuel fills
feed the boat’s single tank.

WARNING
!
Fuel is flammable. Do not smoke. Nev
-
er fill the tank while the engines, blow
-
ers, generator, or other equipment is
operating. Do not fill near open flames.
Fueling Instructions
1. Turn off all breakers on the AC and DC
distribution panels, located in the star-
board cabin upper electrical cabinet.
Make sure the generator is OFF.
2. Make sure your boat is securely moored.
3. Close all port lights, hatches, and doors.
4. Estimate how much fuel will be needed
to fill the tank.
DANGER
!
FIRE/EXPLOSION HAZARD
Gasoline vapors are highly explosive
when exposed to open flame or spark,
resulting in death or serious injury.
• Stop engines before fueling.
•
DO NOT smoke or allow open
flames or sparks nearby, within 50
ft (15 m) of the fueling area.
• Maintain contact between fuel
nozzle and fuel tank fill to prevent
electrostatic spark. DO NOT use a
plastic funnel.
• Fill in an open area.
