or raw sewage. This will be any material from the hold-
ing tank.
Your toilet pumps the material to your holding tank, then
when you are in legal waters to dispose of the materials,
you can remove the materials from your holding tank
with the macerator pump. Refer to the Operations and
Maintenance subject in this section to learn how to oper-
ate the macerator safely.

The macerator pump acts as a garbage disposal in your
home. The pump contains "chopping wheels" that chop
and grind the solid waste into pieces small enough to
pass through the discharge hoses and the overboard
discharge valve.
Important: U.S. Coast Guard regulations require that boats
have a sanitation system on board to control pollution. Waste
is to be stored in a holding tank or other device so it can be
properly disposed of at a shore facility. Discharging this waste
overboard in U.S. lakes, rivers, bays, and sounds and within 3
miles of shore in international waters is prohibited. Check with
the Coast Guard regarding regulations in your area.

10.3 Other Waste Related Equipment
10.3.1 Engine / Generator Exhaust
The subject here will be discussed in the Engine &
Transmission Section. The motivation for placing this
subject in the Sanitation System Section is due to the
fact that exhaust is discharged from your boat. We will
have an entire subject concerning engine and generator
exhaust in the Engines and Transmissions Section. Here
we will simply mention that the exhaust is a gas, Carbon
Monoxide and is very dangerous. Be sure to follow all
guidelines concerning Carbon Monoxide.
10.3.2 Holding Tank
The holding tank on your boat is installed to hold black
water waste until you can safely dispose or pump it
overboard. Refer to the Arrangement Illustrations in the
Boating Safety section or at the end of this section for
location information about the holding tank. Refer to the
Operations and Maintenance subject of this section to
learn how to perform maintenance on your holding tank,
or to learn how to pump it out.
Remember: You must make sure it is legal to empty your hold-
ing tank in the waters you occupy. Some areas have restric-
tions on pumping out black water waste!

10.4 Head System

All vessels with fixed toilets that are operated on the
waterways of the United States and some foreign coun-
tries are required to be equipped with an operable Marine
Sanitation Device (MSD). The Marine Sanitation System
aboard your boat is a waste tank system defined by the
United States Coast Guard as a Type III System. Type
III systems permit operation of the toilet without direct
discharge of untreated waste after every flush. Type III
systems can be discharged at a Marina, Dockside Pump-
out stations or, if in coastal waters, at least three miles
offshore.
Note: Overboard discharge capabilities must remain inoperative
while within the 3 mile limit. This is accomplished by closing the
macerator discharge through hull valve. Refer to the Mechanical
Arrangement illustration in the Boating Safety Section or the
Sanitation Arrangement illustration at the end of this section.
