if the fumes are not released by opening
the engine compartment and operating
the blower for a minimum of four (4)
minutes before starting the engine (even
if the engine has not been operated for
some time), the accumulated fumes may
explode when the engine is started.
To prevent a possible explosion, operate the
blower for at least four (4) minutes before
starting the engine and always when at idle
or slow-running speed. Explosive gasoline
and/or battery fumes may be present in
the engine compartment. Failure to oper-
ate the blower as instructed may cause
improper ventilation of the boat engine and
bilge areas, and fuel vapors can accumu-
late in this area, causing a fire or explosion
which may result in serious injury or death!
Location:
The blower system is mostly un-
seen by those on-board. A two-position
switch activates the engine box ventila-
tion blower, and it is located on the dash
panel. The engine compartment blower
exhausts fumes through vents located on
the transom of the boat.
Operation:
Turn the switch to the right to turn
the blower ON. Turn the switch to the
left to turn the blower OFF. The blower
will operate without the ignition key in-
serted and turned ON. The engine does
not have to be started and running in
order for the blower to work. Switches
can be left on indenitely to continu-
ously allow removal of fumes. Note
that the blower operation does drain en-
ergy from the battery.
Special Note:
The blower must operate for a mini-
mum of four (4) minutes before starting
the engine at any time. The blower must
also be operated during idle and slow-
speed running, but is not necessary dur-
ing cruising speed.
