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
o
F (93
o
C) are considered to be
overheating situations.
NEVER run the boat engine with the boat out of a body of water! Even in
closed cooling systems, some 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!
Be certain to read the Care and Maintenance section of this Owner’s
Manual for important information regarding routine and regular functions
that must be performed. Some of these tasks overlap engine and boat
component attention and should never be skipped. Failure to perform care and maintenance can result in
damage to the boat and engine that is not covered under warranty.
Regularly review the engine temperature information provided on gauges
or video screen. Warning lights and alarms also are part of the system to
provide early warning when engine temperatures begin to exceed acceptable
levels. Continuing to operate a boat that is overheating the engine and drive
train will result in engine failure eventually. Ignoring or failing to take proper steps to reduce the engine
temperature, resulting in damage, is not covered under the warranty.
If an engine overheats, consider several factors before shutting down.
(Turning off the engine when it is
overheated may not provide immediate relief, and in some instances can actually cause additional harm.)
If the boat has been idling for a prolonged period of time and the engine became overheated, attempt to
reduce the temperature by operating the boat at a higher speed, preferably at normal running speed. This will
increase the speed of water flowing through the cooling system, assuming there is sufficient fluid.
If the boat has been running at a higher rate of speed for a prolonged period of time and overheats, reduce
speed for a few minutes to see if the temperature reduces. Running at wide-open-throttle (WOT) for too long
can challenge the cooling system.
If there is no immediately discernible cause for overheating, or if the temperature does not begin to descend
back to the normal range, turn off the engine and carefully open the engine compartment
(but never if there is
an odor of fuel).
Ambient air should eventually cool the engine, but if there is resulting damage to the engine from
overheating, it may not restart and the boat may need to be towed to shore.
Never directly touch an overheated engine. Temperatures can exceed 200
degrees Fahrenheit (93 degrees Celsius), which would cause instant and
serious burns, even through gloves or clothing.
The water pumps on the engine that circulate water and coolant throughout the engine during operation
are essentially inaccessible to the consumer. The circulation pump, which circulates coolant, is located on the
bottom of the front-end accessory drive. If it requires attention, that should be done by a service technician at an
authorized Malibu dealership.
Another pump, the raw water intake pump, is utilized to bring in water from the body of water. The raw-water
pump is located on the top of the front-end accessory drive, adjacent to the alternator. Its purpose is to draw
