Fuel Filters; Use And Maintenance; Fuel Standards; Problems With Alcohol In Gasoline - Four winns FREEDOM Owner's Manual

Dealers are equipped with some general figures on con-
sumption which can be used as a guide until specific
information on your boat is determined. Because of boat-
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.
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
3 to 4 gallons of fuel in the tank. See Figure I5.

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.
NOTICE
Canister-type filters should be changed annu-
ally.
G. Use and Maintenance
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 GENERATING
EQUIPMENT. Investigate and correct the situa-
tion immediately! Have all passengers put on
personal flotation devices and keep fire extin-
guishers at hand until the situation is resolved.
Avoid serious injury or death from fire or ex-
plosion resulting from leaking fuel. Inspect sys-
tems for leaks at least once a year.
Freedom™/Horizon™ Owner's Manual
To help guard against damage, avoid the stor-
age or handling of gear near the fuel lines, fit-
tings and tanks.
The warning label below is placed in aft areas of out-
board boats that are large enough to accommodate a
six gallon portable fuel tank.
No ventilation is provided. Fuel vapors are a
fire and explosion hazard. To avoid injury or
death do not store fuel or flammable liquids
here.

FUEL STANDARDS

Be cautious when using gasoline that contains alcohol.
Refer to the section on gasoline requirements in your
engine manual for additional information.
To conform to Federal Air Quality Standards, the
petroleum industry reduced the amount of tetra-
ethyl lead in gasoline. Alcohol is being blended
with gasoline to help restore the octane rating
lost when the lead was removed. While blend-
ing alcohol with gasoline increases the octane
level of the fuel, it can also create certain safety
and performance related problems for boaters.
A. Problems With Alcohol In Gasoline
Below is a list of problems which may be experienced
when using blended gasoline.
1. 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-
age.
2. 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.
