BLOWER SYSTEM
One of most critical elements of the boat is the blower system. There are important things to remember when operating the boat:
Always operate the blower for several 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 an ON-OFF switch on the 7” Malibu Touch Command (MTC) screen. (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 from the ON-OFF power button. However, operators should always verify that the blower is ON and
operating rather than relying on the automatic ON.
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. 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.
The blower system vents carbon monoxide, a naturally occurring by-product of the engine and drive train operation, through
the exhaust manifold, muffler, exhaust lines and flap, which combine to remove dangerous carbon monoxide and other naturally
occurring toxic by-products from the engine and drive train operation. The emissions primarily are eliminated through the exhaust
flap(s) located beneath the swim platform. 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.
Never allow anyone to be on the swim platform, transom seating or sun pads when the engine is running. Carbon
monoxide fumes are colorless and odorless. Illness and death can result from breathing fumes, even before a person
is aware of breathing them. See the Safety section of this Owner’s Manual for more information regarding this
critical matter.
