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.
DANGER
!
BURN HAZARD
Fuel floating on water which is ignited
can cause death or serious injury.
Fuel will float on top of water and can
burn. If the boat is abandoned, swim
upwind, far enough to avoid fuel that
can spread over the surface of the
water.
CAUTION
!
Use only the fuel recommended by the
engine manufacturer. The use of old,
contaminated fuel can cause severe
damage or engine malfunction. Do
not use fuel that contains more than
10% ethanol, harsh additives or meth
-
anol; damage to the engines and fuel
system will result. Fuel system dam
-
age, related to use of alcohol-blended
fuels, is not covered by the Tiara Lim
-
ited Warranty. Refer to the engine
owner’s manual for specific fuel
requirements for your engines.
3.4 Fuel System Maintenance
Spray the valves, fuel tank gauge sender and
ground connections with a metal protector.
Inspect the fuel fill cap o-ring seals frequently
and lubricate with petroleum jelly or silicone
grease. The o-ring seal prevents water from
entering the fuel system through the fuel fill
cap. If the o-ring is damaged, or you suspect
it is damaged, replace it.
Old, degraded gasoline can affect engine
performance and damage the engine and
boat fuel system. Chemical changes occur as
gasoline ages, reducing octane and causing
deposits and varnish in the fuel system.
If your boat is not operated enough to require
at least one full tank of fresh fuel a month, a
fuel stabilizer should be added to the gaso-
line to protect the fuel from degrading. Do not
allow the boat to sit unused for an extended
period with the fuel tank less than 3/4 full.
Changes in temperature and weather con-
ditions can cause condensation in fuel tank.
Your Tiara Yachts dealer or the engine man-
ufacturer can provide additional information
on fuel degrading and fuel stabilizers recom-
mended for your engine.
DANGER
!
FIRE / EXPLOSION HAZARD
Fuels are extremely flammable and
highly explosive under certain con-
ditions. DO NOT smoke or allow
open flames or sparks nearby when
inspecting the fuel system. Check
fuel lines and all system components
(filters, primer bulbs, clamps and con
-
nections) frequently for leaks, damage
or deterioration. If you suspect dam
-
age, replace as necessary. Surface
cracking on a hose indicates wear—
replace it.
