Backfire flame arrestors are designed to prevent the ignition of gasoline vapors in case the engine backfires.

All powerboats (except outboards) that are fueled with gasoline must have a U.S. Coast Guard–approved backfire flame arrestor on each carburetor.

Periodically clean the flame arrestor and check for damage.
