CHAPTER 3
Blower
Always operate the bilge blower (if installed) prior to starting
the engines or generator. Gasoline vapors can explode,
resulting in death or serious injury. Before starting the engines
or generator, perform the following:
• Sniff the engine room for fuel vapors.
• Operate the bilge blower for a minimum of 4 minutes.
• Verify the bilge blowers are operating properly.
Always run the bilge blower when the vessel is operating below
cruising speed.
This switch controls the bilge ventilation blowers. The blower's function
is to evacuate any fumes and engine exhaust gases that have accumulated
in the lower bilge. The blower must be activated at least 4 minutes prior
to starting the engine. Check the ventilation ducts and black bilge hose
to ensure they are not obstructed. Be careful not to step on the blower
hoses when doing bilge maintenance. Always run the blower when the
vessel is operating below cruising speed.
Horn
This momentary switch controls the audible electric bow horn located
at the starboard bow area. It is protected by a stainless grill cover.
Make sure the horn is tested before each outing, as it can be valuable
in navigation situations and can be used for bridge communications.
Normally there is an adjustment screw on the horn top to alter the
horn tone. Periodically inspect the horn hardware for tightness and
polish the horn grill located on the outer hull side.
