more information about the Shower Sump can be found 
in  that  section.    However,  the  circuit  protection  for  the 
Shower Sump can be found on the 12 Volt DC Panel.
Fuel fumes in the engine compartment can explode.  
Before working on electrical wiring, ventilate  
engine room and disconnect battery cables to  
prevent sparks. 
7.3.7  Ventilation
Ventilation is a very important issue with your boat, with 
the potential for Carbon Monoxide buildup (See Boating 
Safety  Section),  along  with  the  simple  comfort  of  fresh 
air or  air conditioning, ventilation  is a standard  that is a 
necessity.
On your boat, there are essentially three types of ventila-
tion, the air conditioning system (AC system), the blower, 
and  the  Bomar  hatches,  which  supply  you  with  fresh 
air  when  opened.    Since  the  air  conditioning  system  is 
AC powered  (see AC  Electric  Section)  and the  hatches 
require no power, we will detail the blower (or fans), and 
their function, here.
For blower location, consult your Mechanical Arrangement 
illustration in the Boating Safety Section, or the Ventilation 
illustration in the same section.
The  engine  room  blower  is  an  exhaust  fan  which  will 
remove any exhaust fumes from the engine room, as well 
as, removing heated air. 
7.3.7.1  To operate the engine compartment  blower: 
Power up the DC system as discussed in this section.
Turn on engine panel.
7.3.8  Stereo System
The breaker  marked  “Stereo”,  on  the  12 Volt DC Panel 
supplies power to the stereo on your boat. For more infor-
mation about the controls of your stereo consult product 
manual in your owner’s packet.
Do not place facial tissue, paper towels, or sanitary 
napkins in head.  Such materials can damage waste 
disposal systems and the environment.
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 the U.S. lakes, rivers, bays, and sounds and with-
in 3 miles of shore in international waters is prohibited.  Check 
with the Coast Guard regarding regulations in your area.
If the seacock is not closed, the holding tank will fill 
with sea water and could possibly flood the boat. 
7.3.9  Macerator (Not Available)
The breaker marked “Macerator”, on the 12 Volt DC 
Panel supplies power to the macerator pump on your 
boat.
7.3.9.1  To operate the macerator pump:
1. Power up the DC panel as described in this section.
2.  Open  the  seacock  valve  located  under  the  steps  to 
salon.
3. Switch the MACERATOR breaker at the DC main elec-
trical control panel to ON.
4. Turn the  macerator  switch to  the  “on”  position at  the 
Nav Station. This is a momentary switch, you must hold 
the switch to operate.
5.  Allow  the  macerator  to  run  until  the  holding  tank  is 
empty, but no longer.  Running the macerator when the 
tank  is  empty  will  damage  the  pump.    When  full,  the 
macerator will have a low pitch grind.  When empty, this 
changes to a high pitch grind.
6. When you hear the pump speed up (indicates tank is 
empty), immediately switch the MACERATOR breaker to 
OFF.
7. Close the seacock.
7.3.10  VHF Radio
The VHF radio is fuse protected and has power when 
the DC main is turned on. For more information about 
the controls of your radio consult product manual in your 
owner’s packet.
7.3.11  Windlass (optional)
The reset breaker marked “Windlass”, located above bat-
