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 pressure gauges or indicators, if applicable, should read in
the operable range. There should be no obvious physical damage, rust, corrosion, leak-
age 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 extinguisher 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. (There is no longer a pull pin at the bottle.)
Fire Suppression and Extinguishing (All V-Drives)
All MasterCraft V-drives are equipped
with an automatic fire suppression 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 both domes-
tically and internationally this is the HFC-227
system.
It is also possible to activate the system
manually on the domestic boats only. Pull the pin
with the red tag (shown), and then pull the red
fire handle to set the system in operation. (Inter-
national boats are automatic only.)
In case of an engine compartment fire, shut down the engine and blowers be-
fore manual discharge, or immediately following the automatic discharge. Boats are
equipped with a discharge indication light at the instrument panel or on the video dis-
play gauge at the helm.
After the suppression system has been used, the fire extinguisher canister will be
empty. The boat owner/operator should have the canister replaced as soon as possible.
V-drive boats have also been specified to carry a hand-held 2.5 lb. monoammo-
nium phosphate expellant (dry chemical) unit, which is rated Class A (trash, wood and
paper), Class B (UL Approved) and Class C (energized electrical equipment). These
units should be used in situations other than engine compartment fires.
All V-drives are specified for one (1) dry chemical, hand-held extinguisher. This is
in addition to the suppression system in the engine compartment.
Hand-held units should be replaced or recharged as soon as possible after use.
Chemical discharge should be cleaned from all surfaces as soon as possible and prior to
running the boat again, unless operation is necessary to return to shore.
The boat should never be operated following a fire until after a determination has
been made whether operation may result in another fire. If any danger of an additional
fire exists, the boat should be towed to shore or dock rather than running the engine(s).
Consumers who choose to purchase fire control equipment from resources other
than MasterCraft must follow the instructions and requirements as listed within the en-
gine compartment regarding suitability for the compartment volume. These standards
are established by the ABYC.
Following the activation of the automatic
fire suppression system or a hand-held fire
extinguisher, a careful determination should
be made as to whether the boat can safely
be operated. If there is any doubt or concern
whatsoever, the boat should be towed to shore
and/or dock for service by an authorized MasterCraft dealer prior to operat-
ing again. Failure to follow these instructions could result in death or serious
injury/illness.
