fact that exhaust is discharged from your boat. We will
have an entire subject concerning engine exhaust in the
Engines and Transmissions Section. Here we will simply
mention that the exhaust is a gas, Carbon Monoxide (see
Boating Safety Section) 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 holding
tank in the waters you occupy. Some areas have restrictions
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 countries
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 Pumpout
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.
! CAUTION !
Do not use chlorine-based or caustic cleaning
agents, or chemicals such as a drain opening product
in your head systems. Use of these products
may cause serious damage to the system’s seals
and hoses.
10.5 Operations and Maintenance
This section details the system’s operation and maintenance
on the components or systems if applicable.
10.5.1 Bilge Pumps
As we previously discussed in this section and in the
DC Electric Systems Section, your boat has a total of
two bilge pumps. The Emergency, or High Water Pump
(optional), and the standard bilge pump. We detailed the
operations of these pumps in the DC Electric Section
(Section 7).
Here are the steps mentioned in that subject:
10.5.1.1 To manually operate your bilge pumps:
Note: The power to the MDP does not need to be energized in
order to manually operate your bilge pumps.
1. Locate the bilge pump switches at the MDP and switch
them to the manual position.
2. Another procedure to be used in extreme circumstances
involves locating the float switch and manually rotating
the float handle on the side of the float switch to simulate
the float switch being underwater. This will energize the
pump and the pump will operate.
10.5.1.2 Maintenance on Bilge Pumps
No maintenance is required other than ensuring that the
float switches are operational and that there is no debris
clogging the pump intakes.
10.5.2 Holding Tank
The holding tank must be cleaned or pumped out when it
becomes nearly full. There are two methods for removing
waste from the holding tank, either by pumping overboard
in coastal waters, or by dockside pump-out at a waste
facility.
10.5.2.1 Dockside Waste Removal
To remove waste from the holding tank at a dockside
waste facility, insert the hose from the pump-out facility
into the waste access on the coaming (Fig. 10.7) of your
boat and follow instructions at the facility. Instructions
from one facility to another may vary.
