Gasoline is explosive. If a gasoline odor is present or gasoline is visually 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 ttings, deteriorated lines or other problems associated
with the fuel system, call an authorized MasterCraft dealer. Fuel system service on later-mod-
el MasterCraft 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 Underwrit-
er’s Laboratory (“UL”)-approved. Inferior quality components pose a serious safety
threat to you and others, and the use of inferior components may result in serious
injury or death. Resulting damage may void the warranty.
