BLOWER SYSTEM
Models
All
Purpose
The blower system is one of the most critical systems on the boat. A 
natural by-product of operating the engine is the creation of unseen 
fumes. Carbon monoxide is discussed in the Safety section of this 
Owner’s Manual. The engine will also create flammable, ignitable 
gasoline and/or battery fumes. Dispensed into the open air, they are 
quickly diused and pose little to no threat to well-being. However, 
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, the blower will automatically 
run for four (4) minutes when the key switch is turned to the ON 
position. You should always 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 operate the blower 
as instructed may cause improper ventilation of the boat engine 
and bilge areas, and fuel vapors can accumulate in this area, caus-
ing a fire or explosion which may result in serious injury or death!
