Heater
All MasterCraft models oer a
heater option. The heater’s three-
position switch is turned up for
ON (LOW), or turned down for ON
(HIGH).ThecenterpositionisOFF.
Warmed air from an electrically
powered heater box will be blown
from vents within the boat deck. In
regular use, the heater should not
require any routine maintenance.
However, it is advisable to avoid
placing items in front of the vents,
particularly when the heater is in use. The heated air coming out could cause damage.
Never run the heater in a confined space, such as a garage or shop. Fumes from the
engine can have deadly consequences. See also the Common Sense Approach section
of this Owner’s Manual regarding carbon monoxide danger.
Carbon monoxide is emitted from the en-
gine’s exhaust system. Never run the en-
gine without proper ventilation. Do not run
the engine in a confined space or where
fumes may be trapped.
Ladders
Some models are equipped with ladders, which may be
located at the bow or under the swim platform aft. All ladders
have stowable position and operational position. Be sure to
stow ladders prior to operation of the boat. Undue pressure
from the water while underway could potentially damage the
ladder. When opening or closing the ladder, be careful not
to pinch fingers or other skin as all ladders have some kind
of catch to hold them in position and provide protection for
people as they board.
Lighting
Some models may be equipped with incandescent
bulbs in the head, storage areas or in some instances
in the forward and aft-facing lights. These lights are
replaceable as would be any incandescent light bulb.
Other lighting that is L.E.D. will require replacement
along with the housing in which they are contained.
This includes the underwater lights, courtesy lights
and other auxiliary lighting. These lights will need to be
replaced by an authorized MasterCraft dealer.
Also note that the underwater lights should never
be operated unless the boat is in the water. Even
though these are L.E.D. lights, they generate some heat and require the cooling ef-
fect of the water to avoid premature burn-out of the bulb.
Refrigeration
Some models oer optional refrigeration. Note that the refrigerator functions o the
boat’s electrical system. Attention should be paid to the Voltmeter(s) to be certain that
these systems do not over-drain the electrical system.
The refrigerator is suitable for cooling food. If you wish to cool medicine, please check
to determine whether the cooling capacity is sucient for the medicine in question.
