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 the rocker switch located in the aft cabin.
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.

with sea water and could possibly flood the boat.

empty), immediately switch the MACERATOR breaker to
OFF.
