Dealers are equipped with some general figures on con-
sumption which can be used as a guide until specific
ing conditions, speed, weight and other factors common
to your situation, fuel consumption will vary between your
boat and consumption figures developed by Four Winns.
To help guard against damage, avoid the stor-
age or handling of gear near the fuel lines, fit-
tings and tanks.
When the fuel gauge begins to register below the “full”
mark, the gauge readings will drop much faster until it
reads” empty”. When this occurs, the trim angle has
affected the sender reading. When the gauge registers
“empty”, the sender has bottomed out and there may be

to 4 gallons of fuel in the tank. See Figure I5.
To conform to Federal Air Quality Standards,
the petroleum industry reduced the amount of
tetraethyl lead in gasoline. Alcohol is being
blended with gasoline to help restore the oc-
tane rating lost when the lead was removed.
While blending alcohol with gasoline increases
the octane level of the fuel, it can also create

F. Fuel Filters
Fuel filters are installed on each engine. Filters should
changed frequently to assure an adequate supply of fuel
to the engine. Refer to the engine manual for additional
information. The engine manual is included in the
owner’s information packet.
A. Problems With Alcohol In Gasoline
Below is a list of problems which may be experienced
when using blended gasoline.
Premature deterioration of fuel system components
may occur. Alcohol will attack rubber fuel hoses,
fuel tanks, fuel filters, fuel pumps and rubber gas-
kets. This deterioration will lead to fuel system leak-
Canister-type filters should be changed annu-
G. Use and Maintenance
Phase separation of fuel will cause contamination.
Water which accumulates in the tank through con-
tamination or condensation will be absorbed by the
alcohol. This water-heavy alcohol will settle at the
bottom of the tank. This phase separation will lead
to fuel tank corrosion. This may also result in a lean
mixture to the carburetor and cause engine stalling
or possible engine damage.
DO NOT let the odor of gasoline go unchecked.
If the odor of gasoline is noted, DO NOT START
ENGINE. If engine is running, SHUT OFF EN-
GINE, ELECTRICAL AND HEAT GEN-
ERATING EQUIPMENT. Investigate and cor-
rect the situation immediately! Have all passen-
gers put on personal flotation devices and keep
fire extinguishers at hand until the situation is
The use of alcohol additives in gasoline has become
more widespread. Regulations on public notification of
the existence of additives is currently controlled by the
Environmental Protection Agency (EPA). Some states
do require that gasoline pumps display information on
additives (especially alcohol). If alcohol content is not
posted, ask and avoid using fuel containing alcohol if
Avoid serious injury or death from fire or ex-
plosion resulting from leaking fuel. Inspect sys-
tems for leaks at least once a year.
