In using the toilet:
Step 1: Before each use, with the seat lid closed, pull the ush handle
to open the slide valve, then push to close. This relieves air
pressure that may be created in the lower holding tank due
to changes in temperature or altitude.
Step 2: Pull the ush handle to release waste in the lower tank.
Step 3: Push the ush button to rinse the bowl. Push the ush handle
to close the slide valve.
To empty the holding tank:
Step 1: When the tank level indicator shows “FULL,” or at the end of
an outing, empty the lower tank.
Step 2: Pull up on the rear latch to separate the upper tank from the
lower tank. Carry the lower tank to an authorized waste dis-
posal area or a normal toilet. (DO NOT DISPOSE WASTE
IN ANY LOCATION, INCLUDING NAVIGABLE BODIES OF
WATER, WHERE SUCH DISPOSAL IS ILLEGAL OR CRE-
ATES AN ENVIRONMENTAL HAZARD.)
Step 3: Rotate the discharge spout away from the tank and open the
vent on top of the holding tank. Empty the tank.
Step 4: If water is available, rinse the lower tank before reassembling
the portable toilet.
The head is supplied with in-depth instructions, which will be found
in the head and should be removed and read prior to the rst use of
the system. Store the instructions with this Owner’s Manual and other
important material regarding the boat.
Use only rapid-dissolve toilet paper with these head systems, and
only deodorant specially formulated for this type of head system. See
instructions for details. In the event that anything from the head’s bowl
or holding tank escapes, it should be cleaned as soon as practicable.
Failure to clean any spillage may result in unpleasant odors, mildew,
mold and damage to the deck or other areas of the boat. This is not
covered under warranty.
See the Storage & Winterization section of this Owner’s Manual for im-
portant information regarding the preparation of the head for storage.
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). The center position is OFF. 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 conned 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 car-
bon monoxide danger.
Carbon monoxide is emitted from the engine’s exhaust sys-
tem. Never run the engine without proper ventilation. Do
not run the engine in a conned 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 ngers or other skin as all ladders have some kind of catch to hold
them in position and provide protection for people as they board.
