DASH COMPONENT OPERATION

Below is a description of the main dash switched
components. This includes the helm and DC switch panel
located to the starboard side of the helm seat. Read and
understand their operation. Your dash may not include
some of the discussed control devices. Refer to more in
depth instructions to supplement this information which
can be found in the owner's documentation.

Blower

This switch controls the two bilge blowers. The blowers
must be activated to the "on" position at least 4 minutes
prior to starting the engines. This procedure assists in
evacuating any fumes in the bilge areas. The blowers
should be used below cruising speeds. Besides activating
the blower switch a visual check must be done before
starting the engines by lifting the engine inspection hatch
and "sniffing" for fumes in the bilge. Notice that each
blower uses individual circuit protection as a safety
measure. A red icon located in the center of the switch
lights up when the blower is activated. If the light
activates find the root cause of the problem. Normally
there is a hull or equipment leak causing this condition.
