Bilge Blower System
1. Check the bilge areas for fuel vapors or leaking fuel. If you see leaking fuel or smell
fuel vapors:
a. Do NOT start the engine, do NOT turn On any electrical devices, extinguish ALL ciga-
rettes, cigars, and other sources of flame or ignition.
b. Get everyone off your boat.
c. Get trained help to find and fix the problem.
2. Run the bilge blower for at least four minutes BEFORE engine starting, electrical system
maintenance, or activation of electrical devices.
• If you smell fuel vapors and the engine is already running;
a. Shut Off the engine and turn Off ALL electrical devices.
b. Extinguish ALL cigarettes, cigars, and other sources of flame or ignition.
c. Get trained help to find and fix the problem.
• NEVER obstruct or change the bilge blower system.
• The bilge blower system removes
explosive fumes from the engine and
bilge areas.
• Fresh air is drawn into the engine and
bilge areas through the vents.
To make sure the engine and bilge
areas are properly ventilated:
• Use the "sniff test" to check the engine
and bilge areas for fuel vapors before
starting the engine.
• Always run the bilge blower for at least
four minutes before starting the engine.
• Continue to run the blower until your
boat has reached cruising speed.
• Always run the blower when running
your boat below cruising speed.
