2011 Four Winns F-Series Boat Owners Manual

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 I-5.
To help guard against damage, avoid the
storage or handling of gear near the fuel lines,
fittings and tanks.

Be cautious when using gasoline that contains alco-
hol. The fuel system components on the plastic fuel
tanks used by Four Winns® will withstand up to 10%
alcohol content in the gasoline. Refer to the section
on gasoline requirements in your engine manual for
additional information.

F.   Fuel Filters
To conform to Federal Air Quality Standards,
the petroleum industry reduced the amount
of tetraethyl lead in gasoline. Alcohol is be-
ing blended with gasoline to help restore the
octane rating lost when the lead was removed.
While blending alcohol with gasoline increases
the octane level of the fuel, it can also create
certain safety and performance related
problems for boaters.
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 ad-
ditional information. The engine manual is included in
the owner’s information packet.
Canister-type filters should be changed
A.   Problems with Alcohol in Gasoline
G.   Use and Maintenance
Below is a list of problems which may be experienced
when using blended gasoline.
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
correct the situation immediately!  Have all
passengers put on personal flotation devices
and keep fire extinguishers at hand until the
situation is resolved.
Premature deterioration of fuel system compo-
nents may occur. Alcohol will attack rubber fuel
hoses, fuel tanks, fuel filters, fuel pumps and
rubber gaskets. This deterioration will lead to fuel
system leakage.
Phase separation of fuel will cause contamination.
Water which accumulates in the tank through
contamination 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.
Avoid serious injury or death from fire or
explosion resulting from leaking fuel. Inspect
systems for leaks at least once a year.
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
