NEVER use ethylene glycol or Dex-Cool antifreeze coolant. These types of
coolants are not formulated for the requirements of the Malibu Monsoon
engine. NEVER mix the approved propylene glycol coolant with any other
type of coolant, including ethylene glycol or Dex-Cool, even in small amounts.
In fact, these different formulations do NOT mix and will not provide the required cooling protection for
the Malibu Monsoon engine.
Malibu recommends using Sierra Brand, 5-Year, 100,000-mile Marine Grade
Coolant in a 50/50 mix with distilled water to keep the warranty in effect. Sierra is an
environmentally friendly coolant.
While some evaporation occurs naturally, it should not occur at an accelerated rate.
If a closed cooling tank has significantly lost coolant, especially if it is nearly empty,
a potentially serious issue exists. Present the boat to an authorized Malibu dealer for
analysis and correction, prior to starting the engine.
Coolant should be flushed from the system and fully replaced every three
years or 1200 hours on the engine, whichever comes first, and the cooling
system should routinely and carefully be checked for any leaks.
The Exhaust System
Always operate the blower for several minutes (at least four [4] minutes) prior to
starting the engine, running at a low speed or at idle. (Malibu boats are equipped
with an automatic shut-off when the automatic blower system has operated prior
to starting the engine.) This must be done with the engine compartment open.
Failure to perform this necessary function could result in an explosion of the accumulated fumes within the
compartment, resulting in serious injury or death.
Always operate the blower for the required four (4) minutes prior to starting the engine, ensuring the engine
compartment is open. This should also be done when idling or running at low speed. This allows the disbursing
of fumes that otherwise allowed to accumulate could result in an explosion.
The blower is controlled from the command center. (See
Dashes and Video Screens section of this Owner’s
Manual for more detail on how to operate the system.) The blower should come ON automatically when the
system is first powered up . However, operators should always verify that the blower is ON and operating rather
than relying on the automatic ON.
Although the Malibu fuel system works very efficiently, there will always be some gaseous by-product as a result
of operating an internal-combustion engine. These gases, along with the water used to cool the engine (in addition
to the closed cooling system) are routed out of the boat by way of the exhaust manifolds on each side of the engine
to exhaust houses between the deck and hull, and it is expelled out of the system at the transom.
Although much of the exhaust is disbursed into and through the water, fumes still reach the swim platform
and transom area of the boat, including WakeView seating and the sun pads. Therefore, no one should ever be
on the swim platform, transom seating or sun pads when the engine is operating.
