fallen below ¼ of a tank. It has also been determined that
continuous operation with ballast significantly loaded either
port or starboard (rather than evenly distributed) can result
in damage to the fuel pump as it attempts to compensate.
Even with the best of care, some water may get into the fuel
tank or separate from the fuel that is pumped into it. If there
is water present, it will settle on the bottom of the tank. If the
pump begins to reach any water, it may cause malfunctioning in
the engine.
When pumping fuel, do not leave the nozzle unattended in
the fuel fill. Although the fuel system has been manufactured
to avoid sit-back of fuel, and most gasoline dispensers will shut
off if removed from fuel fill, it is always a wise consideration to
provide full attention to the process.
Fuel Information
Whenever possible, use 93 octane gasoline! Admittedly,
there are locations where only lower-grade fuel is available, but
to ensure long-term, high performance, the use of 93 octane is
strongly recommended. Boats equipped with LT4 engines should
use 91 octane fuel at a minimum. For other engines, in such
instances where the highest-grade gas is not available, boaters
may use 87, 89, or 91 octane fuel, but no lower grade. (Boaters
outside the U.S. and Canada should confer with their authorized
Malibu dealer to determine the correct fuel grading, as it is often
graded differently in other countries.)
Malibu strongly recommends the use of the above-mentioned
fuel grades. With continued use over a period of time, the lower
octane fuel could damage the engine, and such damage is not
covered under warranty. Again, if the customer chooses to use a
lower octane fuel than recommended, and it causes damage or
failure, then warranty claims may be denied. Malibu reserves the
right to have the fuel tested.
One of the first signs of improper fueling is a knocking noise
resulting from misfire. Knock misfire will damage the engine
over time. Because the engine is equipped with a knock sensor,
operators will be alerted when the sensor triggers a warning
through the video screen. Do not ignore such warnings!
The engines are engineered to run smoothly. If there are any
symptoms of misfire, hesitation, poor idling, or if the engine
becomes hard to start, such indications should not be ignored.
If the gasoline has been in the boat’s tank for an extended
period (in excess of two weeks), particularly without a stabilizer,
the issue sometimes may be addressed by properly replacing the
fuel with new gasoline.
Never add diesel fuel to the fuel tank. Diesel fuel and
regular gasoline do not mix. Diesel fuel will cause permanent
damage to the engine, and such damage is not covered under
warranty. If diesel fuel is accidentally pumped into the Malibu
system, all contents of the fuel tank must be properly disposed
of on shore, and the engine should not be started until the
system is thoroughly cleared and the correct fuel pumped into
the fuel tank.
When Fueling
When pumping fuel,
do not leave the nozzle
unattended in the fuel fill.
Although the fuel system
has been manufactured to
avoid spit-back of fuel, and
most gasoline dispensers
will shut off if removed from
fuel fill, it is always a wise
consideration to provide full
attention to the process.
Malibu strongly recommends use 93 octane top tier detergent
gasoline. The additives and detergents in these fuels can reduce
the amount of buildup in the engine that adversely affects
performance and shortens the life of an engine. Retailers
selling top tier gasoline can be found at www.toptier.com. (This
information points to a palletizing company so needs to be
removed or replaced with new recommendations.)
Never use E-85 or other E-fuels higher than e-10. This
type of fuel does not contain sufficient additives to protect the
engine nor perform to expected standards.
Never use leaded fuel. Malibu engines are designed to run
properly ONLY with unleaded gasoline. If finding unleaded
gasoline is an issue for a boat owner, check with your authorized
Malibu dealer for assistance.
Never use gasoline containing higher than 10% ethanol.
Some fuel contains methyl tert-butyl ether (MBTE) as a blend
to enhance octane. Blended fuel is permissible as long as it is
CAUTION
!
Do not over-fill the fuel tank. Doing so can cause spillage, which is an
environmental hazard. Fuel tanks also expand and contract slightly to
adjust to ambient air temperature. Over-filling can reduce the ability
of the tank to respond, which can cause damage to the fuel system
and/or boat, which is not covered under warranty.
NOTICE
Review the Care and Maintenance section of this Owner’s Manual
for important information regarding the proper fuel to use, how to
maintain the fuel if the boat will not be used for a period of time, and
other important information regarding the safe use of gasoline in the
boat. Always include a pre- and post-outing inspection of the fuel
system.
NOTICE
Use of incorrect fuel can result in damage to the engine that is not
covered by Malibu. Failure to follow maintenance requirements may
also void the warranties.
DANGER
!
Always dispose of unused fuel properly on shore. Check with local
authorities to determine the proper way fuel can be off loaded from
a boat. Never dump fuel into the water. It is illegal to do so as well
as environmentally damaging. Allowing fumes to be vented can also
cause a situation in which a spark or open flame could cause a fire,
which is extremely dangerous and could result in in serious injury or
death.
