When allowed to sit for extended periods of time, fuel components
can begin to separate or deteriorate. Any water that has intruded
into the fueling system will separate, and because it is heavier than
gasoline, will settle to the bottom of the tank. The current fuel system,
which includes a spring-loaded gas cap, should not allow significant
amounts of water into the system, but operators should always verify
that the fuel filler cap is closed anytime the boat engine is on.
enter into the fuel system. Such intrusion could result in
damage to the engine and is not covered under warranty.
Any time the boat is not going to be used for a period in excess of
two (2) weeks, Malibu recommends adding STA-BIL
the fuel tank. Although there are other anti-degrading stabilizers on the
market, Malibu has found that STA-BIL, when used properly, protects
engines and fueling systems from the harmful effects of storage in
most instances. Note, however, that even stabilized fuel can cause
an engine to idle poorly and run less effectively until the older fuel has
been used up. This kind of damage is not covered under warranty.
of two (2) weeks. Even with the use of STA-BIL, long-
term storage with fuel in the tank and fueling system
can result in degradation of the fuel. This can cause the
engine to perform poorly until the fuel is used, but in
some instances can cause permanent damage to the fuel
system and/or engine. Such damage is not covered under
warranty.
If the boat will be stored for a significant period of time, such as
an entire off-season, Malibu recommends filling the fuel tank full and
adding STA-BIL. Because STA-BIL will eventually degrade, boat
owners should follow the instructions provided by STA-BIL regarding
storage period, temperatures, amount of mix, and any other
information provided by the manufacturer of STA-BIL.
Electrical System
It is important that operators/owners review the Electrical
Components information in the Dashes and Video Screens
section of this Owner's Manual prior to using the boat.
Recommendations and requirements explained in that section
can prevent unexpected issues from arising that will cause
abbreviated outings or premature degrading of components.

Alarms
Note: Audible alarms are functional through the instrument
panel, EXCEPT the Surf Gate transfer alarm, which sounds
through stereo system. However, if the stereo is turned OFF
persons on-board will not be able to hear an alarm.
Tower lights will also flash. Boats without tower stereo
speakers or tower lights do not have this functionality. The alarm
system is equipped on all boats regardless of optional equipment,
and alarm information, including the Surf Gate transfer alarm
information, and it will be available through the video screen.
The boat is equipped with several alarm systems. In general, an
alarm sound is an indication that a potentially serious issue exists.
The low-voltage alarm functions when the battery system charge
has fallen to a level that could result in the boat becoming unable to
continue the outing. The low-voltage alarm will be accompanied by
an indication on the dash. Follow directions as they appear.
Sensors will also alert the boat operator when the oil pressure,
engine and/or transmission temperatures are outside acceptable
parameters. All alarms should be taken seriously, and boaters should
return to shore as soon as possible. Seek assistance from your
authorized Malibu dealer to determine the cause and solution to any
problems that have been indicated.
Cooling System
Malibu utilizes a closed cooling system. This is particularly critical
for operation in salt water or brackish/dirty water. Without the need
for a radiator such as used in land-based engines, the functionality of
cooling system is dependent upon operation within a body of water
or maintaining the appropriate level of coolant/water (in the closed
system). Reducing operational heat from the engine is critical to
ensuring the engine continues to perform.
As Malibu Monsoon engines are configured, temperatures in
excess of 200
F (93
C) are considered to be overheating situations.

external water is used in the cooling process. Without
water to circulate in the system, the engine will quickly
overheat and can do permanent damage that is not
covered under warranty!
