you and others, and the use of inferior components may result in 
serious injury or death. Resulting damage may void the warranty. 
All MasterCraft models are equipped with a fuel fill cap such as 
shown in this section. These caps are hinged, and they snap open or 
closed to seal with an audible click. This is important for the system 
on these boats to operate correctly. Be sure to fully snap shut the 
cap after each fill.
As part of the Annual Maintenance, the fuel filter must be changed.
Due to the pressurized fuel lines, this maintenance can be done 
only by authorized MasterCraft dealers.
Fire Extinguisher And Suppression Units
MasterCraft recommends that boat owners include a check of the 
fire suppression and extinguisher units during the annual main-
tenance to be sure that they are always ready for use. Some units 
may not require annual checks; refer to the signage and labeling on 
the individual units for further guidance.
Other Maintenance
Boat owners are required to perform routine regular maintenance 
as well as annual requirements, as outlined in the engine owner’s 
manual. Some standard or optional equipment on boats may come 
with their own printed information that includes maintenance 
required to keep such components in excellent long-term operating 
condition. Always follow these instructions.
Step 2
Run the bilge blower for at least four (4) minutes to ventilate the 
bilge area each time before starting the engine.
Gasoline is explosive. If a gasoline odor is present or gasoline is vi-
sually observed in the bilge area during inspection, DO NOT START 
YOUR ENGINE! Remove the ignition key from the ignition switch 
and call an authorized MasterCraft dealer for service.
NOTE: If there is evidence of loose fuel fittings, deteriorated lines 
or other problems associated with the fuel system, call an autho-
rized MasterCraft dealer. Fuel system service on later-model Mas-
terCraft boats requires special service tools and special training. 
Due to the potential for serious consequences when errors occur 
in servicing the fuel system, MasterCraft strongly encourages all 
boat owners and operators to seek professional assistance from 
an authorized MasterCraft dealer’s service department whenever 
any service or perceived problems occur within the fuel system.
All replaced fuel components must meet United States Coast 
Guard (“USCG”) and American Boat & Yacht Council, Inc. (“ABYC”) 
standards, and must be Underwriter’s Laboratory (“UL”)-ap-
proved. Inferior quality components pose a serious safety threat to
