Helm Switch Panel-Typical Stern Drive

Typical Switch Panel Shown
The helm switch panel controls various vessel
electrical components. The main battery switch
must be activated for most of the switch functions
to work except for the automatic side of the aft bilge
pump. When a particular component is activated
the blue icon portion of the switch lights up. This
feature is great for night cruising, too. Below is a
brief description of each switch. Note that select
switches may represent optional equipment that is
not installed on your vessel.

Bilge Blower

One of the most important components on board
is the bilge blower. The blower switch controls the
powered ventilation system (blower). Read and
understand the following warning label.
WARNING
GASOLINE VAPORS CAN EXPLODE
CAUSING INJURY OR DEATH!
BEFORE STARTING ENGINE, CHECK
ENGINE COMPARTMENT
FOR GASOLINE OR VAPORS.
OPERATE BLOWER 4 MINUTES.
RUN BLOWER BELOW CRUISING SPEEDS.
Typical Ventilation Blower with Hose
The powered ventilation system (blower) aids
in removing any gas fumes from the engine
compartment and any joined compartments.
Also, the blower removes any polluted air.
Never obstruct or modify ventilation system!
Periodically check the black "4" hoses con-
nected to the blower for tightness. In addition,
ensure there are no holes or tears in the hose
since effi ciency may be compromised. Also,
make sure the attached hose extends into the
lower third of the bilge. This is important since
gasoline fumes are heavier than air and tend to
gather in the lower bilge.
When the blower is activated any fumes will be
drawn up the hose and dispersed overboard
through the aft vent system.
Note that there are other black hoses attached
to the aft vents that may only extend a short dis-
tance from the vent not like the longer extending
exhaust hoses. These shorter hoses bring fresh
air into the engine compartment and allow the
engine to "breathe" so it can run more effi ciently.
They comprise the "natural " ventilation system.
