discharged, then you may purchase a replacement 2.5-pound dry 
chemical fire extinguisher that is rated for Type A, B and C fires from 
an authorized MasterCraft dealer or from another source.
Fire extinguishers require periodic maintenance. Monthly, each fire 
extinguisher on your boat should be examined to be sure that the 
seals and tamper indicators are not broken or missing. The pres-
sure gauges or indicators, if applicable, should read in the operable 
range. There should be no obvious physical damage, rust, corrosion, 
leakage or clogged nozzles. Additionally, if the extinguisher has 
not been used, it should be weighed annually to assure that the 
minimum weight as stated on the label still exists. Any fire extin-
guisher that has been partially emptied must be replaced or taken 
to a qualified fire extinguisher servicing company for recharging as 
soon as possible.
In an automatic/manual system, ensure the pin inserted to protect 
the system at the helm during transit from the factory has been 
pulled to activate the system. This is part of dealer preparation, but 
it is the responsibility of the boat owner to ensure that the system is 
functional. 
FIRE SUPPRESSION  
AND EXTINGUISHING 
 
All MasterCraft boats are equipped with an automatic fire suppres-
sion system. The automatic system operates from sensors in the 
engine room and will automatically release a clean-agent, gaseous 
chemical that does not leave residue behind. In boats sold domesti-
cally and some internationally, this is the HFC-227 system. 
It is also possible to activate the system manually on the domes-
tic boats only. Pull the pin with the red tag, and then pull the red 
fire handle to set the system in operation. (International boats are 
automatic only.)
In case of an engine compartment fire, shut down the engine and 
blowers before manual discharge, or immediately following the 
automatic discharge. Boats are equipped with a discharge indica-
tion light at the instrument panel or on the video display gauge at 
the helm.
