Basic
Electrical Components
All major boat circuits are protected from shorting and overload
by resettable circuit breakers. If a problem develops with one of the
circuits, switch OFF the circuit and wait about one (1) minute. Then
push the appropriate breaker button fully and switch ON the circuit.
If the circuit continues to trip, there is a problem somewhere in the
system. Take your boat to an authorized Malibu dealer to locate and
safely correct the issue.
Circuit Breakers
circuit. See an authorized Malibu dealer immediately to
locate and correct the issue before operating the boat.
The circuit breaker panel is located on the driver's helm shifter panel.
The M235 has a control panel with circuit breakers in the walk-through.
Circuit breakers are resettable, unlike fuses that require replacement.
Fuse Box
In addition to the circuit breakers that control the majority of
electrical activity on the boat, Malibu engines also have a fuse box on
the engine. See photo.
This fuse box aids in controlling various electronic functionality
within the engine. Its purpose is to prevent electrical overload to
various key electronic elements. If the fuse "kicks" off, it tends to be
a signal that certain vital operations have experienced an electrical
surge that could have caused significant damage to the system if the
fuse had not blown.
The fuse box can be opened to replace the fuse. (Unlike circuit
breakers that "trip," a fuse must be replaced.) When possible, have
this function serviced by an authorized Malibu dealer, who can check

the entire system in
an effort to determine
the source or cause of
the fuse malfunction. If
the fuse blows during
an outing, never pry
or force open the box.
The top should pop
off the housing with
minimal effort. Inside
the housing will be
several fuses, the size
is denoted on the top of
the fuse. There is also a Primary and Secondary fuse box under the
dash that contains fuses. Each box has a labeled/detailed picture of
location, fuse size, and which circuit it protects.
There are also one or two fuse boxes under the dash, depending
on the model.
If a fuse blows repeatedly, it is symptomatic of a recurring issue
that must be addressed. Such repair should be undertaken by your
authorized Malibu dealer.
Electrical Harnesses and Wiring
Your Malibu boat is equipped with several electrical harnesses
providing power within the drive train and to various ancillary func-
tions of the boat. Due to the complexity of the boats wiring, much of
which is inaccessible inside the hull and under the deck, any time an
issue is suspected involving the wiring or any of the harnesses, the
boat owner is strongly encouraged to have the boat serviced by an
authorized Malibu dealer.
Malibu dealer. Alteration of wiring from the original
Malibu design could result in shock hazard, potential
spark that could lead to fire, or other dangerous
situations. Any disruption of the wiring from its original
plan and resultant damage to components or the boat is
not covered under warranty. Individuals could also be
injured by such error.
Batteries
Malibu offers batteries as an option. If the boat owner chooses
to equip the boat with batteries of his/her own choosing, there are
certain requirements for starting and the operation of the boat, which
is addressed later in this section. Please review that information
